Set ups!

[Danny McGee]

Seeing as i was bored of always seeing the subject (software issues) on the losi forum i thought id start this one that i'll try and keep updated.

Its basically the setup thats i have been using and the ones that i will be trying out.

Im thinking to start with i'll put up my Worksop setup that has worked really well for the last 12 months. The second will be what i ran last season outside. I'd also like to see other people with losi to put up theres so we can all have a look and discuss! I think it will help us all, myself included obviously. Just copy and paste mine and fill in your bits instead.

Danny what tyres would you run with those setups for the 2wd?

Does your motor choice and gearing vary much on the 2wd?

Ride heights?

I've just bought myself a CR and hit the comeback trail after a few years away from racing so I'm trying to soak up as much advice as possible for the 'new' car.
The last 2wd I owned was a BK2 hybrid but I didn't run that one much. Before that I'd run every Losi 2wd since the XX was released - oh the joy of filling hydra drives with fluid :lol:

[Southwell]

6.5 almost all the time, my gearing is dependant on type of track/ track conditions, generally it will stay the same until places with longer straight etc.

Ride heights?

Level front wishbones and level rear driveshafts is always the right starting point, unless it's flat carpet then you can run lower.

All of last year i was running a 6.5 - 23/78 i think. Although this year im thinking that for the majority of the tracks ill be running a Losi 7.5, purly as the losi motors are faster in my opinion and a bit easier to drive.

Ride height, hmmm well usually i run the front just below level and the rear level. I may tweak that every now and then just to see if theres a difference but generally it stays the same, thats for both indoors and outside.

Good to see ur back with losi. Im sure if we all keep this up to date then it will be a great help to us all. Once i get my lipo stuff i'm going to be hitting the tracks hard to find what i think is a decent set up. Ive got some things i wanna try to this year seeing as i have the ability to machine stuff at work. But i'll be keeping everyone up to date.

p.s i remember hydra drives. Only ever used it a handful of times though, far to meesy!

[Southwell]

Losi motors are better than most ive found, i ran a 6.5 in 4wd since the winter and it's more than enough for most tracks, although the new 5.5 is also very good, nice and smooth with good top end. Ive seen an 8.5 run and was still impressed by the speed of it, ill have 7.5 std setup in 2wd with 6.5 if i need it and probably 6.5 in 4wd but may run 5.5 at some tracks.
I think my choices will be slower motors when i get my lipos to try.

[ashleyb4]

Yea ive had my losi motor in since last winter and it hasnt been out of my car its super smooth super motors and the money makes it even better.

[Reevsey]

Ran my CR today at stotfold and seem to really like the following

Front

Spring - Silver
Oil - 30w
Piston - 56
Shock Tower Position - 3
Wishbone Position - Middle
VLA - Long
Camber Link - 2 B 3 washers under link
30 degree caster as std
30g on top of bulk head
Front Losi standard wing
Thin losi front roll bar - Stops so much body roll in corner

Rear

Spring - white
Oil - 25
Piston - 56
Shock Tower Position - 2
Wishbone Position - Middle
VLA - SHORT
2 degree anti squat
Camber Link - 2 E 3 washers under link on hub
Wheelbase - Medium
losi steel drive shafts
Wide losi wing 2cm gurney

Others
battery's - forwards but not up against servo in std position
Motor 6.5t Losi 25/78
Tyres - Sch Mini spike yellow & stagger rib up front when track dry

Car is forgiving to drive with this set up and well balanced

[Danny McGee]

I dont suppose you tried taking the roll bar off and running the VLA as short did you si? Why did you add the roll bar in the first place? i know you said it stopped the front diving in, but was that just the front end folding over? If so, when that happens i shortern the vla, seems to work for me.

Just a thought.

Cheers for sticking that up though, it'll certainly be one to try out. :)

Also were you running lipos? have you tried putting more weight on the front of the battery strap to move the weight forwards a bit. That really helped at worksop last time i was there.

[Reevsey]

last time i ran the car i tried short and long LVA but i find on short that although the front end does stand up much better in a corner i do loose steering, by running long with the roll bar i found a happy medium, i did try the stiffer roll bar today and it was worse in that it took to much steering away so it does do something although the bars themselves are so thin i did start to wounder if they where doing anything but they do!

No not running lipo still on cells, with all my 1/8th racing my 1/10 gear is getting out of date :p

Weight - i have alot of weight in the car, 25g down both sides on the battery tray in the chassis. I am also running the short KO servo with 40g behind that and 15g under the servo horn so in total including the 30g on the front bulkhead i am running 145g in the car as well as cells!

The weight has made a massive difference, car less prone to wheelie, and on power steering greatly improved

Si

[Danny McGee]

Holy Moly, thats lots of weight!

Cheers for the info Si, i'll give it all a bash at the next meet. Got some of those servos on order so will give the weight bit a try and report back

[tyreman]

Are you coming to Kidderminster this weekend?

[Danny McGee]

Are you coming to Kidderminster this weekend?

Been thinking about it more. What tyres will i be needing? Im asuming BB green spikes? or schumacher greens? What time do i need to be there? What kinda time you rekon it'll be finishing etc

Dont think i have any which is a bit of a pain, but ill see what i can do

What diffrence will a front and rear anti roll bar make to the car? The back end of my car seems to roll alot indoors at oz and was wondering if an anti roll bar would help?

Ash, a job a sainsburys might help to stop the rear of your car rolling around

[DCM]

thats as classic as a panatella cigar (bought at Sainsbury's :woot:)

[ashleyb4]

Anyone got a realy answer:blush::rolleyes:

[ashleyb4]

Solved my own problem now.

A

[Chris Doughty]

Solved my own problem now.

A

how much are you on now?

[ashleyb4]

:p

£4.53 an hour yea!!!!!

Because im under 18

Found out some of the things an anti roll bar can do....

Front anti roll bar reduces low speed steering a little

Rear anti roll bar gives more steering but makes the rear end roll less meaning less traction out of the corner.

So im going to try a rear one.

A

[Reevsey]

Hi Ash

Yes you have figured it out.

Basically if you fit a roll bar it stops the car generating body roll in a corner and keeps the chassis flatter in a turn, this then means the end of the car where the roll bar is fitted is stiffer in a corner which = less grip

So if you fit a rear roll bar the rear will be stiffer in the turn reducing rear grip = more steering

If you fit a front roll bar the front will be stiffer in the turn reducing steering and therefor the car will fell like you have more rear traction.

Thicker the bar the bigger the impact

If you use a thin bar you can get a happy medium like i have been running on the front of my CR. I do not loose much steering but the front is a little stiffer and not wanting to dive into a turn as much.

Hope that helps

[ashleyb4]

Cheers si thats a big help i wanted to confirm it as what i put was what i figured out from reading a guide.

[Danny McGee]

Danny what about the weight of the 2wd?

No idea what the overall weight is. i have 30g's in the battery strap, 15 in the rear bulkhead, the brass bulkhead and then an addition 10 g's up front.

So add those all up and thats pretty much your answer.

I am going to try more weight for the next nat, as it seemed to work for the x factory guys!

[Southwell]

Thats about it, cheers. Only my rear link was different.

[ashleyb4]

Few questions

What setup changes are people making when running lipo i ran my cr for the first time tonight with lipo and it was gash tried it with lots of weight tried it with a bit of weight and tried it with no weigh and it was crap.

Anyone got a good lipo grass setup for somewhere like hinkcley.

My setup above works fine, try laying the shocks down two on the towers though . Unless it's got lots of slow corners.

Weight wise well that's anyones guess, were still playing with that

[ashleyb4]

Cheers danny ill give it a go.

A

[Southwell]

I think weight wise mine is pretty much spot on, although it's very heavy (1750g) it jumps very flat and still has a lot of turn in and high speed steering. I may lighten it at some point but it feels pretty good at the moment. I have my big battery strap, two 5's in the front quarters, two tens in the speedo/receiver area and some lead behind the cells. It seems to have taken away some of the excessive rear end i get and adding it to the front.

[ashleyb4]

Mine was about 17ish might put it back to something around that it did feel better than with the other weight. I added about 70 grams which took it to just over 1800 i then dumped it down to 1500 and both where crap.

A

[Southwell]

Then your weight displacement is possibly in the wrong place. The setups we are using are different too.

Hi Ash, I have had similar difficulties with my lipo set up and have yet to find a set up that feels 'right'. At Kiddy it was understeer one minute then hooking up the next (my excuse for you beating me in the final!:D). I have not tried weighting up to the levels that Ian and Danny have as was hoping i could find a balance without adding a load of ballast. I tweaked a few things at Kiddy after a chat with Danny which helped matters but was still not right. I have found running the front shocks a bit flatter works well as Danny suggested to smooth things out if it's hooking up but can suffer a bit with understeer in places. I'm going to have another play before Sunday and see how it goes this time. The problem is finding a set up that suits your driving style as much as the car itself IMO.

That last bit is VERy true. My set ups are a bit wierd, purely because i have changed how i drive to suit them. Its the only way that i can get enough steering and balance for me. What can i say im strange :)

Ill have a look at the track at the weekend and then change the shock positions to suit. Im fairly sure i'll leave the internals the same as well as the positions of everything else bar the shocks. Like i say, if there are loads of "stop - start" corners then ill leave it as the set up i run is great for them, it basically straighterns up the car quickly and gives me oodles of drive. If its all about corner speed i'd be F()()ked.

We shall see what happens :)

[Ckapp]

Hi Dan
I got a Losi xxx B2K off my bro cos he gave it up, ( yeah :D )

I was was asking if u had any set ups for that or the xxx cr is the same ?
I got a meeting at Oswestry coming up so a set up for there would be a great help.

Thanks Chris

Hi guys,

after running the aero , I took back my losi xx-4, now I've been running it for a few meetings, it's the best car ever :)! But I am still driving with a standard xx-4 WE.
Now, the changes to the car you make like the cr rear end, and the steering rack (I saw it on the report from the national at Talywain), what does it really do to the car handling? I've got some cr wishbones and a set of cr hubs, is that all I need? And do you have to change a lot to your set-up?

@Danny McGee: if you put the lipo behind the motor. How do you attach it? And what does it do to the car handling?

Thanks
Simon

To be hoenst i didnt change anything of my setup again from the rear hub holes. Im sure i posted a setup somewhere on here :S maybe not though.

Im attaching the cells using servo tape at the moment. Ive had NO problems at all in doing that. Just a pain when you run a different back of cells. I found that it give a bit more steering on power when running the diff. I would say it is worth the try, then you can decide if you like it or not :)

Hope it helps

The BK and the CR are two VERY differnt cars when it comesa to handling. TO be hoenst i never really found a setup that i liked on it. ALthough i have a feeling the setup i can on the CR would be better than what i had. I seem to remember that putting in a fair amount of weight made the BK lots better on grass so that may help you.

Sorry i cant be much more help

What made a lot of xx4 drivers shift from the "old" red an silverspring setup to the CR rear end with white and green springs? What are the benefits? More steering, traction?

We are about to get the XX4 out for a try at RHR, hasn't been run for some time. What gearing for a losi 6.5 brushless with cells. I assume the set up will be as of old. I see Danny and others are using XXCR wishbones and hubs. What are the handling benefits over the XX4we ones.

Hi guys,

What could be your setup suggestion for a saddle LiPo equiped XX4 on half carpet half gym floor indoor track?

Thanks for your help ;)

[Randall34]

I have just got hold of a XX4 WE and i was wondering if anyone has a set up or a track like EPR, or tight bumpy astro. I have to run it with a stick pack lipo as i run 2wd too with the same cells. So its a tight squeeze behind the motor.
It has a purple spur (84t i think) so what pinion? (6.5t motor) and no diff at the front just a one way. Is there any advice on adding weight to balance the car? It weighs 1530g at the moment, and is 740g/790g side to side and 670g/860g front to back.
Any advice is appreciated as i haven't driven 4WD since i had a Cat XLS 18 years ago.
Thanks

[magnus]

Been a while since anyone wrote here so, what's your current xx4 setup? cr rear end, white/ green springs, flipped rear pivot?...

hey guys i was wondering if i could get some setup help on the sealed gear diffs. I want to put the origonal gear diff back in my losi xxxsct and was wondering what a good starting point for oil. I was thinking 3k. Have tried using shock oil but it is too light, tried all the way to 100wt. I have in my possesion 1k, 3k, 5k, and 7k diff oil to try. Any help would be awsome. I run in the us on a hardpack clay track, with med grip.
