Cat K1 Aero

[mikeyscott]

New updated K1 coming - http://www.racing-cars.com/pp/Car%20Showroom/CAT%20K1%20Aero.html#

A nice evolution

Carbon chassis
Hex wheel fitment
gear diffs
big bores.

I've got the K1 and like it and ironically have done 3 out the 4 upgrades..

[stegger]

Does it come in Mint or Orange flavour Mikey ? :p

[mikeyscott]

Does it come in Mint or Orange flavour Mikey ? :p

WT? :confused:

I like neither so irrelevant...

[stegger]

Aero !!! :lol:

[mikeyscott]

Aero !!! :lol:

Very funny.... I still like neither...

[johnboy]

Not long had my k1 great car. Do hope schumacher bring an update kit out for currant k1 owners to make into aero spec.

[wrighty]

Theres a few diffrences ..chassis , top deck , layshaft carriers , body wing , shocks , diffs and nut protecters

[Fernandez]

can it carry a shorty lipo ?

[Origineelreclamebord]

can it carry a shorty lipo ?

I doubt it: It has a belt running through the middle, and the bulkheads of the center transmission don't allow a battery to run alongside of it I believe.

Anyway, it was 'clear' it was coming, but I guess I'm surprised by the amount and nature of the updates :o It's looks like a really nice bit of kit, though I'm happy I bought an 'old' K1 last week: I think the ball diffs will work better for me :)

Edit: Just wondering, what's the thickness of the new carbon chassis plates?

[discostu]

IMO This is what the car should have been from day one typical schumacher behind everybody else yet again

[Big G]

can it carry a shorty lipo ?

Given that this car shares the same rear bulkheads as the Cougar KF U4463/4 and there's a shorty conversion for the KF (U4456) you would assume with this conversion fitted you could run a shorty laterally... :confused:

[johnboy]

In what way are schumacher behind everyone else?

[Dodgy Guy]

Any idea how a Carbon chassis will perform compared to the aluminium chassis?
Like the wing. Looks like it's been stole from Batman's car!

[badger5]

I think you'd have to consider the new top deck and the way it's mounted and how the carbon is laid, I don't think we will know for sure how the chassis flex will compare between the two.
I know Schuey are saying the flex has been optimised and for me the K1 has quite a rigid chassis set up so who knows till we get to build the car. Perhaps someone who has seen the car can comment?

[CARB]

Running Carbon or an alloy type of chassis is the racers preference, how many others give you the choice. it seems that no matter on what type of track you race on then having the choice of chassis, differentials, size of shock absorber etc can only be a good thing is it not.

I have changed my SV2 alloy chassis to the composite version and found it gave a softer response to the handling.

I expect in the summer when the grip comes back, I shall return to the alloy version to see if it is better for me under different conditions.

[spud31]

TBH bit gutted, but have most of upgrades already, knew top deck would change as people have been breaking them including me.
I think the chassis and big bores is to satisfy the US guys who were bending the alloy chassis (dunno how) .

[mark christopher]

most of the top uk team run big bores, so logical move to allow set ups to be copied easier

Ive bent 2 in the last year but never broken a topdeck ..the aero top deck isnt a straight swap afaik due to the new mountings

[Origineelreclamebord]

Since I'm new to the K1 (running one, that is)... Where does the chassis tend to bend, and the top decks crack? :confused:

[discostu]

In what way are schumacher behind everyone else?

They realease a 4wd buggy with no big bores no gear diffs all the things the rc drivers are wanting from a £300 kit 6 months later they now decide these things are needed. Like I said IMO behind the the rest

Durango
Kyosho
Xray
Yokomo
Etc

I think this new aero looks the business. Been toying with a change for ages.

The wing will have to do for now.

not forgetting 1 of the main selling points was small bore with big bore spring which THEY found was the best setup...

Odd had my k1 for 12 months.

[Dave Dodd]

So looking forward to Christams, its going to be "MINT" :D

[Dodgy Guy]

The original K1 is a great buggy which goes great (not that great by me mind) and is very nicely built.
The new Aero has a few nice new features.
I'll be ordering one.

[mark christopher]

Double post

[discostu]

Ok you lot

The aero is what the k1 should have been IN MY OPINION I don't give a toss if the small bores where the best setup according to schumacher

I'm not saying the k1 is a bad car far from it I quiet like it but if they had put big bores and gear diffs maybe they would have sold more well at least one more.

Stu.

[CARB]

Or one less ,if someone does not like the way gear diiffs and bopig bores work.

ps do you know the lottery numbers for saturday

[madmulc]

Stu.

I Agree with what you are saying Stu, But in all fairness it comes down to personal choice.

I personally do not like the geared diff but I doo like the small bore shocks?

If schumacher had sold the K1 with geared diffs when it first came out then I probably would not have bought one lol

BUT hay ho lets all just have fun and enjoy racing with loads of banter lol

[Dave Dodd]

personally i like gear diffs especially in 4wd, had them in all nitro vehicles i have used and once you've the oils sorted you cant really go wrong, fair enough that they have the adjust-ability of a chieftain tank but they have worked in all forms of vehicles so why not tenth off road. :D

big bores are a pain but thats prob just me not setting them up. :lol::blush:

it will be my 1st new new electric off road car ever :wub

[brooksy]

What manufacturers should do is supply all cars with big bores and small bores,and ball and gear diffs.......everyone's a winner then!.:thumbsup:

[corsair]

Honestly, I'm abit underwhelmed by this update.

Whether small bore or big bore, ball diff or gear diffs, they can be tuned to whatever anyone desires with the option parts.

As I run mainly on dirt tracks, these are two factors that I will not get it:

1. The flex on the original K1 is rather rigid. It is hard to get it right for the car to be fast on tight infields. Schumacher did not state exactly what the new top deck exactly improve. The arms do come in medium flex as standard now.

2. The new CF chassis seems to be designed exclusively for carpet/astro. The holes under the spur and motor mount will only allow small rocks and fine dust to get in and kill some part of the transmisson...probably the spur first. And no, I don't believe in sticking small pieces of lexan to cover it, or use an undertray.

[mark christopher]

k1 has always had med flex wishbones. there is the option of a carbon or s1 chassis option

those holes can also let stones out!

[corsair]

Using the option carbon and S1 chassis, won't I have to use back the original K1 top decks?

[Origineelreclamebord]

Using the option carbon and S1 chassis, won't I have to use back the original K1 top decks?

By the looks of it, the Aero uses the same bottom mounts for the center bulkheads - also, the alu chassis from the K1 is listed as an option chassis for the Aero.

[MattW]

From what I'm told, the chassis are all a straight fit.

[sime46]

When's it out anyway?

[mikeyscott]

When's it out anyway?

Mid December apparently, which would be next week. A load of the aero parts are listed in stock, so doubt it'll be long.

[dMITIj]

20th of december :)

So should
The b44.2 shold have been the b44
410v3 should have been 410
Xb4 14 should have been. Xb4

You never heard of development?

[discostu]

the b44 was about before big bores.
The Durango had gear diffs but was also about before big bores
The xb4 14 is a revision of a car that already has what the majority of drivers want gear diffs and big bores.

Like I said it's my opinion, schumacher have now released a more appealing car to the current market and what I think drivers want from a £300+ kit.

Stu

[discostu]

Mark you are clearly missing the point lets spell it out IMO IF THE CAR CAME WITH ALL THESE UPDATES FROM DAY ONE THEY WOULD HAVE SOLD MORE AFTERALL THE DHOCKS SND DIFFS WERE ALREADY AVAILIBLE. is this clear.

[mark christopher]

nope diffs were not out when k1 was first released!

?

[badger5]

nope diffs were not out when k1 was first released!

?

+1

And who else gives you the tuning options of ball or gear diffs?

I can understand some comments about how quick the K1 has been updated as it is a bit unlike Schumacher, but it is 1 year since the K1 came out and that was a revolution from the SX series and it seems that Schumacher are developing a lot with this platform. After all X Ray always seem to bring out a new car in pretty much every platform every year yet no one bats an eyelid. But it can look like some have come on here just to knock Schumacher.

The K1 Aero looks like an awesome car and builds from a very good platform. The change to 12mm wheel hexes is a big plus and should make it easier for people to convert to Schumacher, which hopefully will result in more sales for this British company.

Out of interest will the K1 option S1 chassis fit the new Aero? If so this has no cut out for the spur gear and should help the guys who run on dirt/clay.

Hi Sam,

Updae towers
New wing
New centre mountings
New steering pivot
Nut guards for the towers
?

When are you running yours at TORCH?

[mark christopher]

Plastic steering parts same numbers as k1 but new hex nuts bearing holders
New body?
Top deck

[mikeyscott]

Sorry, yes very true, I classed the top deck update as part of the chassis update.

Do like the look of the new body

[DanB4]

Hoping to get an Aero and paint it a la Masami 1987....decals too

[Moss Models]

Picked mine up yesterday and built it today.

I have to say the build quality is superb. This year I have built 3 AE cars, 4 Durango's, 1 Losi and 4 Schumacher's. The Schumacher kits are the best by far. They all have good points and bad points but the Schumacher has the best instructions with all the parts easy to locate due to the bag per step. Can't fault them at all.

New body and wing look great!

[Samspeed1]

I wasn't counting the body and wing, only chassis changes.

Soon Mikey soon

[cryer-evo]

hi all dose any one no if the cat sx3 diff will fit in this car ?

[mark christopher]

no you need the K1 ball diff

[cryer-evo]

dam it . going to order my aero tomorrow

[badger5]

hi all dose any one no if the cat sx3 diff will fit in this car ?

If you have SX3 ball diffs then all you would need is the pulleys to convert them.

My Aero is on it's way (to importer) so hopefully I'll have mine Monday !! :thumbsup:
Getting FAB too...
Q: I would like to know how neccissary the alloy upper shock tower housing were on the K1 ? (I will get them as soon as the budget allows anyway)
But wondered if it was an upgrade that should be done immediately - especially if you consider it may prevent snapping a shock tower too.
How many of you broke the stock housing before upgrading ? I wonder if the Aero's nut guards work to add overall integrity & durability to this area .... thoughts ?

A worth while upgrade for the front, although the front nut guard should stop the shock mounting bolts from digging into the racing surface.

Front but guard should be a massive improvement especially if you race anywhere like southport!
I was for ever replacing nuts if it rolled on the Tarmac or cobbles!
Definetly a good upgrade depending on how it wears obviously a but is cheaper than one of those protectors!

[cryer-evo]

Orderd mine today 😃

[traffman]

I really quite like this kit.

Looks like a well rounded model.

[cryer-evo]

Has any one had a chance to play with there aero yet as looking at wot diff oil to start with ?

[shaungooner]

Tom C's setup from the worlds http://www.petitrc.com/setup/schumacher/setupcatk1/K1_TomCockerill_Chico2013092629/

7K front

10K rear

[sime46]

I've built mine 12.5 fr 7k rear as recommended by a team driver. We'll see how she goes.

[cryer-evo]

Cool seams very odd that they are running thicker oil in the rear :confused:but can't ???? The pros

[cryer-evo]

Also shox oils as I believe it comes with 3 hole pistons

[Dave Dodd]

Cool seams very odd that they are running thicker oil in the rear :confused:but can't ???? The pros
I believe It would aid steering imho. I used to do this with my savage truck cos that hated turning lol.

[mikeyscott]

I ran 10/5k in my K1 and loved it's first run. Will get a 3rd diff to test further.

Will be interested to hear people's views re aero vs original K1. Admittedly I went to big bores from day one.

Need to get some 3 hole pistons, drill and test etc

[Mossy]

i've been running 20k front and back all year and most of the team has now started to move towards that. At the worlds we changed diff oil but on a very different surface to what we run in the UK.

I run 20k in the KF aswell.

When filling, put oil in each of the 4 corners, then rotate the gears and add more oil until its level with the centre spindle.

I've been filling mine like this all year and it seems to be the best starting point.

Si

[cryer-evo]

Will be run mostly on hi grip astro so 20k front and rear is a good starting point yes moss ?

[cryer-evo]

is there a under tray for this car as would be a shame to scratch the carbon chassis or are people just putting a film over it like dinoc 3m carbon vinall ?
got mine all built just got to get it painted up:thumbsup:

[Dave Dodd]

Got mine today :thumbsup:

Need to get some 20k for the diffs
Got some 50wht for the shocks :)

[mikeyscott]

Got mine today :thumbsup:

[cryer-evo]

I take it the standerd k1 shell will fit on the aero ?

[cryer-evo]

Hi all I have got the 3 hole pistons in my aero with 30w rear and 35w losi oil front and it would appear to me there is way to much pack . If I drop my car fully loaded up from say a foot hi it dosnt compres at all ? Is wot is every one running I only have losi oils

[mikeyscott]

I believe most are drilling the rear pistons to 1.65mm

[cryer-evo]

First time out today started with 35 front 30 rear losi oil and it was way to hard swopped out to 30 front 25 rear still to hard I think but much better now put 25 front 20 rear fills better but run out of track time to test but my god this car is so much easyer to drive than my old sx3 flipping loving it 👌

[cryer-evo]

?? For you all when I was coming out onto the straight if I wasn't lined up and got on the gass it would go into a massive tank slapper wot can I change to stop this ? Track was damp astro

[mark christopher]

stiffen the damping

[sime46]

Is the diff oil too thick/thin?

[Dave Dodd]

https://scontent-b-lhr.xx.fbcdn.net/hphotos-frc3/1533863_10203024423594909_194984474_n.jpg

Using rims n tires I already have glued up and getting tested on Friday. :thumbsup:

[cryer-evo]

My diffs have
12500 front
10000 rear

Shox
30w losi front
25w losi rear
Kit pistons

Front camber -2
Rear camber -1

Tyres where ballistic buggy green

Every thing els kit
Felt rilly good apart from it getting the odd tank slapper on but it was very slippery icy astro track

I have now put
25w oil front
20w oil rear
Fills much better on the bench but track time will tell if it's any better

[juergen_jl]

Why are you using more camber in the front as in the rear?

[cryer-evo]

It was very wet out on track so left rears as up right as I could get away with with out it grip rolling and the front added a bit more camber again to stop grip roll but still have as much drive out of the corners this might not work for every one but it worked for me

[RETRO R/C]

Hi guys,

These parts will bring your K1 up to the very latest AERO spec for the 2014 racing season.

Cheers

Darryn Johnson

[johnboy]

Rather expensive to do might as well buy a new kit. The price of every item is £251.87 a kit costs about £320 not a massive difference.

[RETRO R/C]

Absolutely - for sure not the very cheapest way to go - however for those on a tight budget - it still a a significant amount.

People can do the upgrades slowly or all at once. Either way - they will still be running a mighty Schuey!! :)

Cheers

Darryn

[Origineelreclamebord]

Or you could simply update only the things that really matter - I'll admit the carbon chassis, gear diffs and big bores are the most expensive bits, but I doubt the new carbon chassis, top deck and layshaft mounts from the Aero will differ a lot from just buying the 'old' carbon chassis - and for budget conscious K1 owners it may be more interesting sticking with the pin wheels too...

Right? :)

[mark christopher]

List is wrong. Can not upgrade k1 small bore shocks with just bushes and bodies. You would need caps collars shafts and pistons.

Any one els had a chance to race or practise with the k1 aero yet ???

[Hans Wynants]

i raced it this weekend @ MIO Oss indoor. was the first time out with the car buth after a couple of battery's the care was fun to drive . with almost standard setup it responds very good. i only changed my steering turn buckles and bolt with the one from Xray , the original ones always jumps loose with the smallest collision... after the change with the xray parts the problem was fixed.

I actually ran these in my original k1 but would prefer a ball cup to pop off.
I crashed my k1 and damaged a fair few parts because the rose joint didn't pop off.
Thanks though.

[corsair]

Another alternative is to use the pro ball cups U3500.
These almost never pop off, unless the impact is really huge.

I used these on my SX, but tried these recently and found they're binding the suspension up, will be checking ball studs etc.

I'm just on kit options and haven't had a problem thus far

I've already tried the U3500 and the Lunsford one's for the Schumacher CAT K1 but both pop off on little impacts...

[hansie]

Hello all and especially Carlos,

That is a nice option to have.
Did you run the car yet with this conversion?
Where did you get the 125t belt?
there is one on the schumacher site:

U2238Rear Belt; 125Tx4mm - SST Axis

Is this the one you used?

Greetings

Hans

[Carlos69]

Hi Hans,
Haven't tested it yet, .... soon !
The belt is from RobotShop Inc. item # RB-Ftr-38.
I didn't know Schumacher had one too. thanks ! The belt I got feels stiffer, it has a bit more reinforcing.... which does increase resistance. I will try this one for now until I can get the one you mentioned.
Cheers
Carl

[hansie]

Hi Carl,

Thanks for the belt part nr.
I wonder if the belt i found is strong enough, its from an older car.
Let us know how it went!

Hans

[RETRO R/C]

List is wrong. Can not upgrade k1 small bore shocks with just bushes and bodies. You would need caps collars shafts and pistons.

Thanks for your input! ;)

I posted up the items that I received from the factory to upgrade my car to Aero spec, hopefully someone other than the truly awesome will have gotten some benefit from the list I posted.

So yes - not all parts are required or "mandatory".....I simply posted up the items so that people could reference the list - if they wanted to do the whole lot or just pick and choose - the list was there....... as it had not been done previously.... Apologies for the lack of the list to upgrade to big bores.

Live and learn I guess!! :thumbsup::p

Hi all was out with my aero Sunday at worm / Weston super mare mendip track car is sweet but it was snapping out on me mid corner is there anything I can change to stop this ? I notice a lot of the team drivers are running low hi on the rear arm mount wot is this for and conditions ?

[dMITIj]

So how do ppl like this new Aero compared to the K1?

and is anybody using the FAB in this new Aero?

what will be good option/spare parts?

[dMITIj]

No one? :confused:

No one? :confused:
what a shame :thumbsup:

I run the K1 for a while and a lot of updates make sense to me toward a better car, big bores, carbon chassis, stronger top plate, gear diff so yes the Aero is a better, easier car to drive.

The FAB will work of course, never got the chance to try it (but did on SX2/3).
Try the car without, I did not thought it was absolutely required as the car was great as is.

Thanks for the reply :)

how much room is left for the shorty to swell up? before it touches the belt? lets say the shorty gets warm under load.

Hi rear arm pin height changes roll centre and makes rear looser.
If its mid corner and on slippy astro are you running roll bars? also try shocks on rear

[cryer-evo]

No not running roll bars as don't have them will give putting the rear shox behind the tower a go and see if that helps

Get the rear roll bar kit will make a huge difference and support your car on the high grip astro tracks

[cryer-evo]

Might see if I can get the ones of my sx3 to fit on

[Dave Dodd]

Absolute must haves for the Aero?
Anti roll bar kit - front or rear or both
Anti squat kit
Anything else

Cheers

I dont understand why schumacher would bring out a gear diff car aimed purposely for high traction tracks, yet include a carbon chassis. The alu chassis would prove to be a better chassis for astro I would imagine.

I was thinking of buying a k1, but I would rather have ball diffs and the carbon chassis, too bad they dont do that combo as that would be best on dirt.

It depends a lot of the quality of the carbon fibre really, the average RC grade stuff is cheap and flexible because it has little carbon fibre and a lot of resin. A nice example of high grade carbon fibre+resin used in F1 is roughly twice as stiff as 7075-T6 aluminium.

I don't know exactly what Schumacher use for the carbon chassis', but the shock towers are densely packed with layers of carbon and I'm amazed by the slim construction of all the parts - to do this they can't have saved money on bad quality materials.

Combine this with the listing by Schumacher as 'optimized flex' (not 'more' flex) and I think you can't make a conclusion on it's flex characteristics just based on the details you have - for that you'd probably have to compare them side by side.

If you do want to be sure of getting more flex, why not take a K1 with an S1 chassis (which is a glass fibre chassis I believe)? :eh?:

Ive just got my new K1 Aero on Thursday, and completed the build over the weekend, now just awaiting the SP 6.5 motor and ESC arriving to finish it off

This is my first buggy for competing that Ive bought in about 10 years as just returning to the sport. I will be mainly racing on an indoor sports hall surface, which looks very slippery. Anyone got any tips for a novice to get back up to speed?

[Dave Dodd]

Has anyone got a mid - low grip astro base setup ?

cheers
