Hi im running my TRF 416x on a hall/Gym floor with really low grip and my rear end has no grip what so ever could anyone advise

Setup
Standard setup out the manual
with 2 degress camber on Front and rear
and Steering is toeing out 1.5 degress
tyres Schumacer mini pins yellow compound

My front grips no issues

Kind Regards
PS its that bad that when i go round a corner it more or less will donut.

try laying the rear shocks down. (mount on the furthest point towards the wheel on the wishbone, furthest inside on the shock tower).

That should give less steering and generate more rear grip.

Using a differential on the front may also help.

maybe you do not have enough droop at the back, and your suspension or chassis is tweaked.

When is is donutting? when you get on the power? or on the way into the corner?

a quick fix would be to try removing the rear roll bar. If your on kit springs as well, you may want to go softer on the rear. Can also try removing the shims from underneath the rear suspension blocks (remember to re-set your droop).

Just some initial suggestions.

Try .5 camber up front and 2.5 or 3 in the rear. Maybe go white/yellow on your springs front and rear. Run the rear blocks flat on the chassis (take out the .5 shims).

I agree with Syndrome. I would also try taking the toe-out out of the car and either go to zero toe or 1* toe-in.

Make sure your rear diff is not over tightened

I was at a race recently where rear traction was pretty bad, but steering was good. The only thing (at the time) that made the car better was gluing the front sidewalls. I still had enough steering, but the rear grip issue went away. I need to get my hands on some springs harder than the whites, 'cause I think there's something to fixing rear grip by taking traction away from the front. These cars TURN.

Thanks guys I'll give all that ago and let you know but it wont be until 2nd cheers.

TryHard - it's donutting when coming out the corners or about 3 quaters of the way round it's a real pain. Also if my diff was to lose could this cause it. I'm new to RC Racing and this is my first TRF.


Front sticks like clue and goes like stink of the straights.

rebuild your diff and go up in front droop

don't lay your rear shocks down either that gives less rear grip

How much front droop also how does this affect the handling.

Agree with that... shocks in will make the car initially feel like it is softer, but will stiffen up a lot more in roll.... going out on the tower will make it more linear.

Hey guys I did as you said added more front droop and reduced back also removed roll bar and it seems to have fixed most of the issue handled alot better.

Thanks for the help

Ric.

+1, that is correct.
