Sound to me is your car front end is going up during on power ,try reduce the droop ....
kick up work great for bumpy track....if the track is smooth take out the .025 ....or try with the oneway diff

the more caster make the car coming out of the corner faster...but going in slower....

Run a higher roll center in the Rear that you do in the front. I experimented with this over the weekend (1st time out with the car) and it made the biggest difference of all the changes I did to the car. I was running 4 tabs in the rear (f/r) and 2 tabs in the front (f/r). I was running on a medium grip HUGE asphalt track, so fast corner speeds are needed. To get good exit steering on asphalt I also believe you need either a oneway or a spool (the latter being my preference).

-lower front ride height than rear (i.e. 4mm front, 5mm rear)
-tighten rear diff
-softer front springs or harder rear springs
-one way for improved getting out of the turn speed
-let of the throttle sooner

This is the servo Im going to be picking up for my TC4. Im new to racing and RC, my RTR servo went...my shop says this is good.

I have the same problem, I use to run foams and decided to change to rubber so had my first run on rubbers this weekend, with foams I was just as fast as anyone else through the corners but with the rubers (CS27) the car seeemed to scrub too much speed. only got 2 runs and then got rained out so didnt have much time to work on setup. I may be able to try some of the sugestions next weekend.

What made things worse is that I had so much traction on my first run that I would traction roll if I came through the turns just a little too fast. it was better on the second run but still had 2 traction rolls.

let us know how increasing the rear roll centre works out for you

SA Racer:
Raising the roll center should also decrease you traction rolling.

I have found that this car is most sensitive to roll center changes rather than spring tuning. I could not personally tell much change in corner speed changing to stiffer front springs or softer. The car was still very "locked in" It seems like the rear generates a lot more traction than the front. THerefore by decreasing rear grip when raising the rear roll center, it allowed the car to rotate better in 180 degree corners after highspeed short shoots (which at my local track means 60-80 feet).

By going to a softer front spring you might get more initial steering, but not increased corner speed, you also tend to lose exit steering by doing this, which might translate into equal or less corner speed.

Hello, I am not a perfect driver by any means but I have spent a lot of time with the car lately and I can offer my experience. I have been racing on carpet but I think it will apply. I have been back and forth between rubber and foam on this car, and I have had traction rolling problems with each setup. The tracks I have been racing at get very grippy by the end of the day.

1. Don't put traction compund on the outside front of foam tires. Clean them and start over if grip is too high. On rubber I have seen, but not tried, the sidewalls have super glue applied to them. It wont stay on long but it seemed to work.

2. Reduce the camber up front.

3. Raise the roll center. Rubber needs weight transfer to work right but if you're traction rolling you have enough grip. IMO.

4. Try a harder compound tire.

Thanks for the info, ill let you guys know the outcome, what do you guys prefer on asphalt, foam or rubber?

also does anyone here have a good base setup for medium size, medium grip asphalt using rubber.

Thanks
Peter

you guys might not agree but i really like the pro-line v-rage tyres. for carpet , i find them the best comprimise between foam and slicks
and the foam i used was fast tyres and slicks were take-offs 27s
just my 2 cent worth

Thanks BeerBaron, I did find reducing camber helped a bit, im on 1deg al the way round. raising the rollcenter is what ill be trying next.

not sure which Schottky Diode to buy? as in specs? if anyone can help me that would be great thanks
