Default Brushless Rubber TC4 set-up?

I've been running a Sedan with a 4300 brushless for a while now. I had a TC3, I now have a TC4. I've always had rear traction problems coming out of corners. It may be that the brushless just has too much torque at low speeds.

We are running CS-27s on Ozite. What kind of set-ups give the car more traction on exit? Looking for general, like more "rear toe-in", ect.

It's not too bad for the first few minutes, but the last 2 can be a handfull.

Are there any set-up sheets yet for brushless?

Softer rear springs, softer rear sway bar, less front caster, increase rear toe, lengthen wheelbase. Obviously these will do things greater or lesser so try one and see what its like.

Ok, I can lengthen it and go from 2 (total castor) to 0 by changing the front kickup. I'm Using green rear springs and -3 rear-toe.

I'm also using #2 pistions with 30# oil.

Also, the track is very smooth.

I've heard front one-ways are bad for brushless (makes even harder to drive, spin on brake). Confirm?

Thanks

Gordon, assuming your setup was decent with a stock motor, you can make some radio changes that will make the car MUCH easier to drive. When I ran my XXX-S in brushless, it was very loose on power until I turned my throttle expo way down..like -50% at first, and as I got used to the powerband, I gradually turned the expo back up.

Chassis things that will help:
more rear toe in
more front droop
At times if you shorten the rear wheelbase, you'll put more weight over the rear axle which can give you more grip too.

And battery back I assume?

I was playing with my 3PK throttle speed too. I was trying to tone down the full throttle torque.

have the battery forward so under acceleration it transfers more weight rearward, planting the the rear better
