2wd Proto - CR2

[OldTimer]

As the losi guys have been missing out on the mid motor fun, it was time they got in on the action :lol: so we will be testing the CR2 at the Oz national this weekend and seeing how it goes.

Sorry about the yellow wheels ;)

[Southwell]

Sexy time. :thumbsup:

[jimmy]

OOOH ! now then. This looks like a proper job, I'll make sure to snipe some pics:thumbsup:

[OldTimer]

No problem jimmy :D

[GRIFF55]

Don't be sorry about the wheels, they make the car:drool::drool:
Very nice once again from you Mr Atomic

[jono83]

that looks awesome

[OldTimer]

We will see if you can break the new front tower on Saturday Mr Griff :lol:

[ashleyb4]

Thats a very nice car Jonathen. But not keep on the front tower sorry.

Have been wanting to play with the idea of mid motored.

A

[GRIFF55]

ooooo i'll strength test it for you:woot:, i'm sure you said you had a spare.

[freud]

Oohh Oohh Nice Job Super J
You the best!!! :thumbsup:






I like Wheels Yellow :thumbsup:

[DCM]

That has actually made me think.... mmmm, Losi..... slap me now!!

[nitrokillah]

oulala Jonathan . it's looking good .

will there be futur plans to make the atomic trademark TUB CHASSIS ??? :drool::drool:

[DaveG28]

Looking nice, want one!!

[Darren Boyle]

JC I knew all those CR spares you were getting werent for a standard car.....now I know what !!! Nice work mate..

[peetbee]

:wub:wub

would a stick pack lipo fit in there?

[Garry Driffill]

J,

Is it all the origional gearbox, Or is it cusutom? Looks fabulous!

[OldTimer]

J,

Is it all the origional gearbox, Or is it cusutom? Looks fabulous!

Its all original gearbox, no dremeling needed, just two holes need drilling one for the layshaft coming out the other side of the gearbox, and one for the motor plate.

[maxoo]

nice!!!!

[MK Racing]

Looking Good :thumbsup:

You must have been busy yesterday, as you only got the XXX-CR in the morning:woot:

[Belsten]

deffo needs white wheels :thumbsup:

[RSharpy]

Looking good Jonathan :thumbsup:

If you ever fancy converting an RB5 I've got 2 spare cars, your welcome to have 1 to have a play with :D

[J_WOODY]

that looks great :thumbsup:, if testing goes well, will you making it available as a conversion kit?

[Alex H]

Nice work! One doesn't need to get separate losi shocks on the side either!
@Jonathan, no 4speed gearbox planed?

Looks very promising. A great companion to my Durango I attend to get:thumbsup:

[charles08]

Wow that looks nice ! :thumbsup:

Very curious about the handling .

Let us know !

Sorry about the yellow wheels ;)[

Manolis has already made one and tested at the euros in italy i think. Pics are on oople somewhere and his had a nice carbon fibre chassis.

[GRIFF55]

those yellow wheels did the trick mate! Car went really well and responded well to setup changes (not many made as it felt goooood!)
Can't wait to get my own now:thumbsup:

[OldTimer]

I think getting the car to 7th in the B final, your best 2wd national result is a good start:lol: and 11th in the 1st round and i think 14 in the last round is not to bad with a bit of guess work on the setups lol.

I guess it did not help i only got to the track 10 minutes before you went on for practice :D

[GRIFF55]

and the driveshaft builder:lol::p

[Garry Driffill]

Thats a great result!

[Twister]

S2 was superb and now this? you are a wizard Jonathan.. :thumbsup: I´m biding my time to get my hands on this sweet thing:drool:

[Alex H]

This reversed gearbox thing and the motor mounted the way it is. Is it a considerable difference between having the motor mounted that way it is now or like on the S2 and X6? If so, are you Mr C going to make an 4speed version as well for this machine? Otherwise it going to be a lot cheaper than the S2 I suppose:).

[Thomas P]

A source tells me that as we know the Losi have less steering then the B4, so the opp mount of the Gearbox wount affect so much..

If so, are you Mr C going to make an 4speed version as well for this machine? Otherwise it going to be a lot cheaper than the S2 I suppose:).

Hi Alex, As per Thomas's post, my thoughts when designing the car were that the B4 has a load of steering, when you move the motor to the mid position and move the cells forward due to the motor now being in front of the diff, you lose a lot of rear end grip, as we found with the 3 gear S2, with the 4 gear S2 it helps redress the balance and generates more rear end grip again similar to a rear motor B4. Remember both the S2 & X6 use the B4 front end.

Now with the xxx-cr its a car that has not got a lot of front end grip / steering, but has a great rear end based around the xx4, so running the factory 3 gear gbox reduces the rear end grip but balances the car out with more front end grip / steering which it lacks. If we used a 4 gearbox on the CR i think we would be back to square one with a understeering car due to the extra grip generated by the 4 gear gbox.

How it runs on low grip nobody knows, but as your not hacking the car / gearbox to bits, its a very simple job to fit the front and rear ends back onto the standard chassis if the cr2 struggles on low grip, but having said that on saturday for the 1st practise when the track was damp with dew, it did not seem to have any real problems, but a true low grip track would be a better test.

And cost wise i think it will be in the region of about half the price of the s2 conversion kit.

[Dunc]

Does this mean its definitely going into production at some point? - I want one! :thumbsup:

And cost wise i think it will be in the region of about half the price of the s2 conversion kit.

[GRIFF55]

In that first practice it also had yellow minispikes all round and wasn't that bad. If it had bliks on it would have had plenty of grip in the wet too i think. It had plenty of steering and was a very forgiving car to drive:thumbsup: nice one JC

[Thomas P]

I like it a lot...more Mid motor cars to the market..personaly i like thin cars more :D


EDIT Jonathan @ the race http://www.oople.com/forums/showthread.php?goto=newpost&t=24939 any CR2 here :P?

[Alex H]

Thanks Jonathan and Thomas! I am definitely interested in one:thumbsup:

Send it here. I'll test it on low grip tracks for you. :thumbsup:

[Thomas P]

Yes Jonathan, send a copy over to Swedens Loooose,sand tracks :D i can asure you will have a fullblood test on it =)

[Danny McGee]

Yes Jonathan, send a copy over to Swedens Loooose,sand tracks :D i can asure you will have a fullblood test on it =)

So what can we say about this weekend running the new car then :)

Lets put it this way, im really happy with the way the car now feels, so much so that i was able to keep up and beat some 4wd's this weekend at Robin Hood.

Any questions about it feel free to fire them at myself, Brian Preddy or the main man himself ;)

Danny

[OldTimer]

It was a tad surprising that you could keep up with the 4wd's, forecast at the moment is dry for ERP so will be another interesting run for the CR2's :thumbsup:

[GRIFF55]

Where did you go, rhr was it? Jon did you do kiddy?

[OldTimer]

Went to RHR instead of Kiddy Griff.

[GRIFF55]

Was the setup changed much from Oz? Bet the car was amazing on high grip astro:D

[OldTimer]

Same setup as Oz:thumbsup: i think Brian ran the same and just changed the front camber link, and danny was similar but was playing with various things to see what effect they had on the car. Both Danny & Brian were running the newer spec car.

Yes was good in the high and lower grip areas as well. Felt safe to drive and jumped very well, but was a little over motored with the 6.5R in it. I found the S2 was very similar handling but a little easier to drive for me with the 7.5L in it.

[GRIFF55]

Where's mine then!!!! Got some building to before epr unless you want to bring me one at 8 in the morn again:lol:

[Danny McGee]

Where's mine then!!!! Got some building to before epr unless you want to bring me one at 8 in the morn again:lol:

And there was me thinking that my 2wd was slow with a 6.5 in. :lol:

I'll happily let folks know my set up at the weekend if your wanting to try it. Seemed to work really well at RHR, may have to tweak it a little for the layout that EPR will do though. But that will have to wait until after the first practice

[Robfo]

Right i'm having a look at building my new CR2, Why does the slipperclutch have to be on the righthand side of the car? Is it simply because it will loosen itself?
It seems like alot of messing about if thats the only reason, surely another solution would be better?
I'm probably missing the point......

Any help would be appreciated

[GRIFF55]

When i ran the first version at Oswestry, the slipper was on the opposite side, but it needed a spacer between the gearbox and a hole drilled in the opposite casing for the layshaft. This enables a std speedo to be used(non reversible). But at epr i ran the slipper on the std side.
Thanks again for the loan of the car Jonathan. Cracking tool that helped me to get into the C final.

Ran it for one round in the 4wd class too as my 4wd was in pieces on the table. Put a faster time in too;)


Correct me if what i have said re. slipper is wrong JC?

[Robfo]

Ah so i don't have to hack the gearbox if i use the Losi speedo in reverse, thats going to made it alot easier.

While i'm thinking about it, is there any way of using the standard Losi front end rather than the NT part, i've got the NT part on order but i don't think it will be here any time soon. Whats the difference between the std part and the NT?

[peetbee]

It's not that difficult to fit the motorplate on the right hand side, but yes a lot easier if you can reverse rotation via the esc!

Because the NT has a flat alloy chassis the nose is designed to fit that, the CR nose has different moulding to fit the plastic chassis and associated bracing to stop it flexing.

[DaveG28]

Sounds like the car is still running awesome! Any update on when joe public can get one?? I assume it'll be the "new" version that's released?

Also, what are the details behind the "NT" stuff?

[Belsten]

Cant wait to get home and start building mine

[tyreman]

The cars will be the versions that the Horizon team ran at the EPR national.

I think the aim is to have them available after Jonathan gets back from the Belguim GP.

To complete the kit you will need the XXXnt lower kick plate, B4 servo posts and B44 battery posts.

still going great Dave, the parts needed are the ones that brian has stated above. Send oldtimer a pm to see when he can sort you out a kit.
Oh and you need a xxx cr of course, you wont regret it!!!!

[Chris Doughty]

could you not use JRX-S posts for battery posts and JRX-S servo mounts? keep it all Losi?

[Darren Boyle]

I was told it was "all Losi" at the weekend (apart from the Atomic Carbon parts of course)

[GRIFF55]

Not sure on those parts guys as i have had no experience with them. But if they are similar, i don't see why not.
I'm sure mr Preddy can answer this.

You have the LHD version of the CR2, which means no hacking of the gearbox, simply unbolt off the xxx-cr and bolt onto the CR2 chassis, and simply tick the box in the losi speedo software to reverse the rotation of the rotor.

There will be a RHD version at some point for speedos which you cannot reverse the rotor direction.

Atomic-Carbon battery posts will be included in the production version of the kits, we have used B4 servo mounts at the moment just down to most people being able to get them quickly if there not in there pitbox.

The current plan is to start production of the CR2 LHD when i get back from the belguim GP, and at a later date the RHD version.

Hope that clears up the questions :D

[Robfo]

Thanks for that, just waiting for the NT part and the car should be running at this weekends regional! Not by me though :cry:

Just to point out that if you run the motor in the opposite direction, you will be running negative timing..............

[lochness42]

Just to point out that if you run the motor in the opposite direction, you will be running negative timing..............

Nope if he'll run it sensorless.

[Fabs]

Something his speedo isn't capable of.

[DCM]

ah, yes, some motors come 'pre-timed' if they don't have adjustable timing, and those that do, sometimes can only go as low as 0'.

[OldTimer]

We have used Novak & Losi motors with the Xcelorin S speedo with zero problems. I have only seen Danny's CR2 at RHR and it was very rapid and that had the rotor reversed. And i think all the CR2's that ran at the weekend at EPR also were running reversed rotor as well.

I do wonder if there is something built into software to compensate the timing if the rotor is reversed, as you can adjust timing in the speedo software.

[Southwell]

Mine was perfect with the rotation reversed on a Losi speedo and motor. :thumbsup:

[Stu]

[GRIFF55]

novak motor and losi speedo in mine (well jonathans) car at epr. Worked a treat:D

[Fabs]

All I'm saying is if you have timing on the motor you'll have negative timing if you run it in reverse... So you better off running "min" timing on the motor.

I thought though that it was decided a 4 gears gearbox wasn't a good idea because you lose steering... But what's been done now is exactly the same, any reasons for that ? Why not just make a 4 gears gearbox ?

[Chris Doughty]

not exactly, 3 gears very much determins that the 'kick' of the motor will be the oposite way to the wheels.

it just depends which end of the motor the shaft sticks out

a normal running motor runs in the same direction as a 180 degree flipped motor running 'backwards'

[Fabs]

Yeah that's exactly what I mean... Why run the motor the wrong way round instead of having 4 gears ?

[Chris Doughty]

Yeah that's exactly what I mean... Why run the motor the wrong way round instead of having 4 gears ?

but when the motor is running 'backwards' its installed in the car 'backwards' (180 degree flipped) - so it actually 'kicks' kicks in the same direction.

with a 3 gear gearbox the car would have to actually drive backwards to get the kick of the motor to be the same as a 4 gear

with 3 gears, the spur turns the same way as the wheels, its a physical impossibility to get the kick of the motor the same way as the wheels.

[Fabs]

We agree on that...

It's now similar to having a 4 gears gearbox, but with 3 gears and a motor that goes backwards.

But I was told at Oz they didn't wanna do that to get more steering, the car I saw back then had the motor spinning normally, with modified gearbox to get the shaft out the other side.

[OldTimer]

See post 33 ;), and you don't need to design a new gearbox to have the 4 gear effect.

[Fabs]

So you concluded that you had too much steering with the original design ?

[DaveG28]

Can't quite make out from the above pics, is it possible to use a full size servo and still fit the excelorin in, or only low profile?

[Chris Doughty]

We agree on that...

NO, its absolutely nothing like having a 4-gear gearbox.

if you hold the motor it will kick in one direction
if you turn the motor 180 degrees so the shaft is facing the other side - it will kick in the OTHER direction
now make the motor run backwards - it will kick in the ORIGINAL direction

[Southwell]

Can't quite make out from the above pics, is it possible to use a full size servo and still fit the excelorin in, or only low profile?

I have a standard servo in.

The gearbox hasn't been modified, just turned around.

[Fabs]

I see what you mean chris, sorry my bad... So you CAN'T get the same effect as a 4 gear without one...

[Chris Doughty]

indeed, its physically impossible unless you have an even number of gears.. (or an idler gear between spur and pinion X-5 proto stylee)

[Fabs]

Yeah my brain just wasn't working this morning... Wait... That's normal it never works :woot:

[bondy]

that would be right ! get some work done !

[Fabs]

Shut up you I don't talk to traitors :p

[DaveG28]

Is the front shock tower standard or is there an Atomic one people are running on it?

[Southwell]

The team are running the standard shock towers.

[GRIFF55]

i run an atomic one. there are two types, a single or two piece one:drool:.
The two piece has taken some nasty abuse too:D

[chemax92]

About running backwards sensored speedo:
If you exchange at the same time two powerwires and two sensor wires, would work OK?

[lochness42]

About running backwards sensored speedo:

I don't think so - you'll get probably quite high negative timing on motor no matter what you'll do.

[Danny McGee]

The team are running the standard shock towers.

Untill my new ones come to test that is dude :) will prob be for next weekend, wherever that will be I'm not sure

[DaveG28]

Is the excelorin system that works the 1/10th sensored one? I assume so bug just checking!

[Southwell]

Yep.

[OldTimer]

I have just uploaded a new page on the website here (http://www.atomic-carbon.co.uk/cr2) with more info on the CR2 plus a base setup and a list of speedos which i understand are reverse rotor capable.

Hopefully over time more setups will be added ;)

[mendocino]

That's a really nice work Jonathan, as always I should say.

I wanted to add that every sensorless bruschless esc is also reverse rotating capable. (You just have to invert 2 motor wires) so you can add the Tekin R1, Mamba max and the others that I don't know. :D

[Belsten]

just finished building mine and cant wait to try it tomorrow :D

[DCM]

where you racing, Mr B?

[Belsten]

with you, cobra mate

I can't friggin race tomorrow, got all the kids, pop down though, grope the car and what not....

[Belsten]

bummer, make sure you wash your hands first then before you grope :woot:

[GRIFF55]

use the setup jonathan has posted for there mate, should be a goodun for that track.:D

[DCM]

warm them first too?

[Belsten]

if you dont mind

[DCM]

not sweaty warm, like Jacko's when he visits a nursery..... just warm

[strobe]

Good luck with the new car Belsten:p

[Kusal]

Can you also use a XXX BK2 for this conversion?

[tyreman]

Yes as the screw holes are in the same place.

[DaveG28]

Random question, if it comes with the battery posts but not thmb screws, will the thumb screws needed be the same size (well, I mean the gub screw really I guess) as the B44 ones or are they off another car??

[Belsten]

I dont think it comes with battery posts mate

[_sleigh_]

Yes as the screw holes are in the same place.

Does the lower gearbox of the BK2 fit ok?

[OldTimer]

Random question, if it comes with the battery posts but not thmb screws, will the thumb screws needed be the same size (well, I mean the gub screw really I guess) as the B44 ones or are they off another car??

The final production kits will be supplied with custom made brass battery posts with a 4-40 thread. I could do thumbscrews but they work out very expensive and push the cost of the kit up a lot.

You have various options for thumbscrews the ae ones, the trishbits version, or just use a csk washer super glued to a csk screw ;)

The thing i like about the car is you can just nail the throttle out of a corner and it will just straighten itself up, no understeer, no drama. If you can do that with an X6 then no wonder i couldn't stay near them with a rear motored XXX. :thumbsup:

Is it slippery clay tracks or is it a killer there to?

[caciqueconnection]

Hi Jonathan,

After reading all I find about this kit, I'd like to buy one ¿Would you send it to Spain?

I'm so interested so that it won't be any problem travelling to UK to get it...but I'd preffer the cheaper way (more unpersonal I know) :D

In other point, one trivial thing -but important- is how you achieve all that efficiency on the track while remaining or increasing beauty from the original donor kit. Nor that ugly designs forgetting that.

[Danny McGee]

If anyone does try a different setup to what ive been running (i think thats the setup thats being used by everyone?) then can you post them on here. The moew information we have the sooner the car will get better. At present i havnt tried anything too dis-similar. But over the coming weeks ill get the setup posted.

Cheers

Danny

[Migs]

Danny, congrats on the results with the car, i'll be ordering the conversion kit shortly, how does it compare to drive vs the standard cr

thanks

[OldTimer]

@ Justme - no problem shipping to the USA.

@ Joelwhite - i need to put some miles on the RHD gearbox which is suitable for standard speedo's so at the moment i would guess towards the end of August.

@ bbq - We have not run the car on dirt or clay, so a unknown sorry.

@ caciqueconnection - No problem shipping to Spain ;)

The website has now been updated and there is now a blank editable setup sheet online kindly created by Arno at Petit RC.

[caciqueconnection]

An order from the sunny Spain will be placed soon then.

Now I have to think where to place a "parental advisory explicit carbon" sticker :D

Danny, congrats on the results with the car, i'll be ordering the conversion kit shortly, how does it compare to drive vs the standard cr

Well, from the testing we have done the car stays much flatter under acceleration (the rear) due to this is does not power understeer as the CR has been know to on various track. It also feels a lot easiler to drive consistantly when your near the edge so to speak (not that im there very often)

It also jumps more consistantly from the little time ive had on bigger jumps.

Think thats about it, although ive probably missed something :)

To jonathon, i might be missing something here, i cant find a way to order the kit on the website.

[snige]

het just wondering when the rhd version of the cr2 will be made available and will it be the same price as the lhd and where does a recevier fit?

[joelwhite]

See post 129 aboud rhd avalibilty. There is enogh room behind the servo for speedo and rx. Dont know about a price difference really shouldnt be probably just a tanny case with the hole on the other side.

[OldTimer]

het just wondering when the rhd version of the cr2 will be made available and will it be the same price as the lhd and where does a recevier fit?

The RHD will cost a bit more due to the extra parts needed, ie layshaft spaces, motor plate spacer and longer screws etc. I would guess at the moment around £20-£25

Time wise i don't have a date yet as i want to get a decent amount of testing on the rhd gearbox to ensure its reliable.

[snige]

thats great lads thanks for the info i will stay posted to await its arrival:)

[DCM]

Is the chassis wide enough to accept a stick pack, across it's girth?

[elvo]

Is the chassis wide enough to accept a stick pack, across it's girth?


Blasphemy!!!

[DCM]

I only have stick packs :(

[caciqueconnection]

And sticks are cheaper, easier to find and you have tons of models/specs to choose.

Because weight distribution and the possibility to use it in both 2WD and 4WD...in other case sticks are the point nowadays.

[peetbee]

Is the chassis wide enough to accept a stick pack, across it's girth?
It doesn't look like it Steve, the extra bracing on the sides would raise the cells too high.

will there be a body for the car?

A stick will fit across (just), but it would as pete says have to sit on top of the braces. So not brilliant, but it wasn't designed for them. Securing them would be difficult. Have a look at daves' car steve and you'll see what i mean.
I believe there is a narrow shell in the making so when you run the car with the side pods off, it ill be a nice snug fit.;)

[DCM]

So, the chassis is wide enough, thats all I am interested in, if I find a XXX CR CHEAP enough, I could well be tempted!!

[Southwell]

Brians got one for sale, it's not cheap cheap but it is practically brand new.

[DCM]

lol, I said CHEAP, I already looked at it, and with the AC2 conversion on top, almost puts it in the X6 price range!!!

[millzy]

I two would get a kit if i could get a cheap xxxcr- im not paying silly money for a 2wd

[GRIFF55]

have a look at belstens car width first mate. the tp lipo sticks i have are exactly the same width as my chassis(proto). Its well worth every penny guys, awesome car!

[DCM]

He is away with you guys this weekend, isn't he? I am sure it could be 'adapted' to take sticks too, as it isn't the same sort of mass that the old 'NiMH' packs.

[Belsten]

yup nationalising this weekend

[millzy]

I had a good look at Daves on friday - and it dose look good
i have a good guess why you want to run sticks - im not usre how much room you will have

[migsy]

if you go mid-motor and try to use a stick pack, you'll need to file the insides of the chassis a little.;)

[CBRDEAN0]

Well, from the testing we have done the car stays much flatter under acceleration (the rear) due to this is does not power understeer as the CR has been know to on various track. It also feels a lot easiler to drive consistantly when your near the edge so to speak (not that im there very often)

It also jumps more consistantly from the little time ive had on bigger jumps.

Think thats about it, although ive probably missed something :)

Having watched your car at Southport National today I would say you are very close with your setup already.

Car looked really stable and quick - deserved TQ in round 4

Cheers.

I must admit, for the 4th round my car was very good. I had changed my car every run during the day to try and make the most of the conditions and for the final round and the final itself the car was ace.

That setup will defo be staying on there for stotfold. Cant wait for it now :)

[Belsten]

got to say I was extremely pleased with mine too, loved driving it more than any 2wd ive had before. Just need to drive better now :blush:

[GRIFF55]

BIG :thumbsup: from me too, it was the best the car has been so far. Just a popped balljoint in round 3 ruined it for me:cry:

[DaveG28]

Guys,

I'm building an XXXCR up from scratch to use (my CR2 arrived today). D I build in the following manner or am I missing anything?

1. Build whole front end, just on NT front kick up rather than CR. No other differences between the kickups? Then attach to CR2 chassis.

2. Same with rear end except use the CR2 rear plate rather than the kit one? Then gearbox/shock tower assembly just drops in backwards? Does anything else need reversing on the assembly other than the wing mounts? Everything else exacty as per XXXCR instructions?

3. Where is the shock tower spacer (very thin small piece of carbon with a single hole) used?

4. Do people keep the stock XXXCR driveshafts on the losi kit, or change them for something a bit more blingy?? Any other hopups on the losi side that are well worth it?

Cheers!

[GRIFF55]

Having not built one from scratch dave i can't gaurantee this is right.

All sounds good to me and the carbon spacer goes under the lowest point on the rear tower/brace assembly touching the chassis. You will see the gap when viewed from the rear. My car has no extras apart from lead and a front wing and its grrrrreat

[lochness42]

Is the chassis wide enough to accept a stick pack, across it's girth?

Check my conversion - I belive that you can do same thing with CR2 after small modifications.

[paul01ews]

Hi All,

Dave, i have been building mine too so it was good to find out where the small peice of c/f goes!

Check out the first piccy posted on this thread as you will need to take the gear box apart and drill some holes to mount the motor plate/ spindle on the other side..

Question for all out there... is there a front brass bulkhead for the cr like the trish bits B4 one?.. if not i will try and get some made up???

Paul.

[Belsten]

yes mate, both trish & ghea do one for the cr:D

[OldTimer]

The website is updated with build info for both the LHD & RHD versions ;)

There's no gearbox mod needed for the lhd one as far as I'm aware, on that one you just mount the whole assembly backwards and reverse the esc??

[OldTimer]

Yep no mod's at all for the LHD version, only for the RHD with details of what to do HERE (http://atomic-carbon.gforceimages.net/cr2/index3.html)

[DaveG28]

Is there more than one page to the lhd build guide? It's says "goto page" at the bottom but my browser doesn't show it as "clickable"?

[OldTimer]

No just that one page, need to remove that bit at the bottom ;)

[joelwhite]

So it looks like a rhd version is avalible now for us with non super cool speedos. Is that correct.

Only have 2 Times' to test the car befor the euros in spain

Im running the set up that i thinks been posted already. Only change is, ive laid the rear shocks in on the tower. Simples! :)

[bbq]

sweet! but just so i dont get it wrong its the same one as on
AC web page?

And you didnt say if you were going to the Euros :D

[bbq]

First test today and it is fast. What strikes me is how much
more controled the car feels, and it is so much more controled
from apex to exit and you can attack harder and erlier.
I am thinking of puting on a front wing as i had some hard work
to level the car in the long jumps were you cary alot of speed

I used the set up from the AC sits with the only differans in
shock oil 37.5 front red piston #56, Green spring, Location
3-middle on the arm and tower. Unscrewed 2 turns for more droop

rear 30wt red piston no limiters and unscrewed 2 turns, pink
springs. Location 2- midle

used à GHEA brass bulkhead (40g)

What should make the car faster is when i get the GHEA
pistons in, as that just calms tha car down à bit more in the
bumpy sections. they are the chill pill.

Jonathan and all other guys involved.
Awsome job dude's

Track was my home track massive grip and all Astro many jumps more then in this picture

When is the RHD version going to be released? Also will the car have its own shell or do you use the xxxcr shell?

[bbq]

I forgot to put in My set up report that i was running the RHD

[OldTimer]

When is the RHD version going to be released? Also will the car have its own shell or do you use the xxxcr shell?

I will hopefully have ready towards the end of next week a batch of LHD & RHD CR2 kits.

Part of the range of option parts does include a slim shell to be used with revised narrow side pods, also there will be XD front slim towers as well along with some other parts.

[Junior Z]

If you reverse two motor wire and if you change the position of sensor wire on the plug in a side of the cable.

You must be able to use all ESC like LRP and Speed passion ESC on the CR2 conversion kit LHD version? I'm wrong?

[Patryk Rybarczyk]

Hi, I am from Poland, i am driving xxxCR, and i am thinking about this carbon conversion. What is the difference about left motor side and right?

I dont know where i can buy it, I found it only here http://atomic-carbon.gforceimages.net/cr2/index.html but £145.00 is to much for me :(
Maybe somebody of U, have it used for sell?

Thanks.

[GRIFF55]

it has only just been released mate, so i very much doubt you will find a second hand one.... You will not regret getting the kit as it is so forgiving and easy to drive fast.

bbq, get yourself some extra droop towers, these save unscrewing the shock bottoms and give plenty of droop;)

[tjf]

So with the LHD and reversed speedo do the motors have any change in characteristics running the opposite way?

[Danny McGee]

Nope :). well not from the CR anyway. Im going to be testing this after the nats so will report back if i see any differences

[fastinfastout]

I am assuming the tekin esc with adjustable timing will have no affect on the reversed motor rotation in sensored mode?

[millzy]

no- it will be fine- if you have downloaded the new softwear it has the option to reverse the motors rotation

[fastinfastout]

I know the latest tekin 200 firmware has reverse option but

what I meant was......

does advanced speed control timing(timing boost on tekin rs) work with a motor that runs in reverse rotation?

Cos the last I heard, it will run in negative timing.

the timing boost on the tekin speed controls are a huge benefit to control spec motor class's ie. 17.5 BL

[discostu]

i would have thought it would run as if it was in normal mode.

[fastinfastout]

I hope so, I will find out in a couple of weeks.

[ravens]

Are you using ballast under the saddles?

Set the timing on the endbell to 0. Then any timing you will add either in sensorless or sensored mode will be added to zero and will be positive.

However in buggy we don't run in sensoed mode but dual mode only, unless you're racing with a 9.5 or higher turn motor I advise you to run dual mode.

[CBRDEAN0]

I might have missed it on the AC web site but how do I order a CR2 RHD ?

The kits arn't showing in the store

[GRIFF55]

drop oldtimer a pm on here mate. As for ballast under cells, some use a sheet of lead the same as the cells but i just use enough to get it up to the legal weight limit:D Hope this helps

[OldTimer]

I have a limited amount of both LHD & RHD kits in stock at the moment, so drop me a email or a pm and i can sort you out ;) i am away on business tue-thur so i will not add them to the online store until i am back.

Also the CR2 XD front towers are now in stock.

Back from the Euros!
The car is a amazing machine! i did my best euros, did a 17 in round 4 with three mistakes
and was looking goood until my speedo burned in round 5.
Otto from sweden did his first euros and his first run with the car at the euros and
ended up i the B-final with the cr2.

We had alot of help from Brian Preddy and he had alot of help from us i hope =)
i wish i had the chance at the Euros to try out the LHD with the idelgear that Otto
was running in his car. you can sse it in the Oople report

Now this weekend we will have the swedish championship on a clay track and i will
see how it performs there, i think it will do good

I saw this - nice idea. Only question is how would you change ratios ?

Unless I'm looking at it wrong - the centres between the pinion and the idler are fixed ( idler uses motor mount screw as fixing ) - will that not mean that the gearing is also fixed ?

[rc_penguin]

changing spurs

[CBRDEAN0]

changing spurs

That will give small changes in ratio but i've seen some guys need to change by a couple of pinions depending on track & tyre size

[V-Rossi]

I'm using 22-27T pinions, not easy to adjust this precise by only changing the spur gears. Pinion adjustment comes in handy when grip levels are for instance extremely low. So maybe you could compensate the 'loss of tuning options' with the ESC settings besides changing spurs?

[bbq]

Any news??? how did the race go and how did the car perform on clay.

wouter.z

well we were 3 CR2 in the final but we all strugled with rear traction beond the
apex piont on the exit of the corner. it lacked drive and you hade to be soo
smooth in the begining untill you got some speed.
it was wery good going in to the turn and sliding it in, it was like driving a 4wd
but i was struggling with it on exit.

Trackconditions were super dusty bone dry, wery poor traction.
in the morning when it was damp the car was ACE and it was amazing to drive
but as son as the track dried up we strugled.

we need alot more testing on a track like this to find out what does what
and how to improve traction in the rear.

/Daniel

Ps so no one gets it wrong i still love the car and i think it is a big improvment
from the CR but the track this weekend was like driving on ice

[V-Rossi]

I will be running the CR2 as well this winter and next season, will be posting my set-ups for low-grip tracks here. Maybe we could create a set-up topic to compare them?

[wouter.z]

Thanks for the reply. Do you think that the carbon (stiff) chassis has anything to do with the lack of traction? maybe a softer chassis will smooth out the ride on rougher/ lower traction tracks. Thats 1 point im a bit afraid of.

Maybe more toe-in will help. I know a lot of x-factory drivers use 4 degrees instead of the 3 degrees on the cr2 (I think).

wouter

[Thomas P]

outboard toe will affect the car. i run 4 deg on my S2 (3 on block and 1 on rear hub) it helps a little..

[V-Rossi]

Still lots of ways to improve rear traction, after a bit of testing during the following months I'm sure we will have a decent set-up. Besides, BBQ said grip levels were extremely low. For me the S2 was especially good on high grip, but now the car is as good as the X-6, B4 and Losi on low traction surfaces too.
@BBQ: which tyres were you using? For instance a Losi Big Shot Red could be very good in such conditions.

[ravens]

Been using ifmar studs red or bowties M3 on low traction surfaces with good results.
JC double dees green on hard packed surfaces,with high grip, are very good.

Managed to get the perfect under lipo ballast on ebay :) 50gr

Big shot reds was the controlled tire.
I think that what i need is more time to test set ups on a track like this.
the car has so many good parts i dont think it will be an issue.
I was also trying out a new speedo and i had some issues with my motor.

BTW i any one haven't tried the new speed passion ESC it is the thing to
have in youre 2wd for sure.

[fastinfastout]

does anyone have a set up for hard packed twisty clay medium traction track?

I didnt know where to start off, so used the matt chambers starting set up, and its not very good for the cr2. Too much on power steering, and also too much understeering entering turns.

Sounds like it needs less caster

[ashleyb4]

Has anyone got a detailled description of what is required for the idle gear mod and how to do it.

A

[rc_penguin]

Right,
A idler gear, bearings with the screw sized hole in, long enough motor screw to go through idler, washer, motor plate an into the motor, 20 tooth pinion, some varios washers.

Simply, get your idler and bearings and screw. place a bearing on the screw then the idler, then place some washers on the screw to space the bearings out to stop them pinching when tightened, place the other bearing on the screw then another washer to spacer the gear off the motor plate, and mount the assembly where you would the top motor screw normally.

Ok? :lol:

[ashleyb4]

Yes i was just checking as earlier when i looked at it the bearings sat very loosely on the screw.

A

[peetbee]

Any idea what the sizes of the bearings for the extra idler gear would be please?

[rc_penguin]

1/8" X 3/8" Losi Part No. A6909

Thats what ive used anyway, there the same bearings that are used on the idler in the gearbox originally.

[peetbee]

Thanks, that's lucky as I've got some on order!!

[ashleyb4]

Well tried the idler on as per above with a 20 tooth pinion and the pinion idler gear mesh seemed tight.

when you buy idle gears there are two in the bag one small and one big.
make sure you take the right one!

usualy when i order i get 2 idle gears in one bag. one big and ine smaler
its for the BK2 and the CR gearbox

[Danny McGee]

Its the standard CR one that you want. The mesh is "slightly" tighter than normal but it will be fine. Alternativly you could do what im going to do and use a smaller spur and have a play about with ratios too

Thats just some of the things to test before the next set of nats next year

What are people thoughts about trying what the X factory guys have been doing?

i.e. a rear hole bar, the additional toe in, I tried CVD for the last leg at the weekend and thought they were better although i have heard they tend to get "hurt" quite a bit so may end up changing them more often that usual.

Anything else that people think we should be trying?

[bbq]

Danny next on my list is the BK2 rear arms and pivot block =)

i'm using a losi bodypost mounted in the position of the last locknut at the back of the chassis. I think the body post is from the xxx-4 but it comes in a packet with something else, maybe the wingmount?

[ottoswe]

Here is a few things im gonna try before the indoor season starts.

•raising the gearbox, hopfully it makes the car squat more during acceleration (more rear traction)

•cvds

•new motor/gearbox brace.

On low grip tracks you need alot of weight i run 150g under the lipo and abit of lead under motor.
0 degree pivot block helped alot to get more rear grip during acceleration.
Camber link 6-B with two washers, short vla,
shocks: 3-inside, 20wt with orange piston and white springs.

Car is getting better and better, but still needs more on power traction


6-B with 2 washers is my starting point on both low and high traction tracks. It will make the rear end work alot more, and it wont give positive camber throu the corner

try increasing the rear shock oil to 30/35 and run a pink spring and give it some anti squat if you have none on it. it sound like all your weight transfer is being obsorbed with your soft spring oil setting and not pushing the tyres into the race track.

Discostu. I started out with the astroturf setup and it was pink spring, 30wt and alot of anti squat. 30wt and made the car spin out on straight.

I want to try these things to be able to run a harder supension. But it was fast by far the fastest throu the slow corners and chickanes

are you sure its more on power traction you need or is the car generating over steer on power making the rear end break away ive been racing my cr on dusty polished wood floor and on power traction is not a problem maybe you could try a shorter front link inside on bulk head and in side on hub and raise the inner to about 3.5mm it will make the front end roll more but will help the snatch on mid corner and on power.
