got directed to this link, figure I post my issue here and see what is recommended.
I am running VTA class, using a shaft drive style car (Academy STR4 Pro II).
As the track owners are getting ready for snowbirds I believe, we ran the track in the reverse direction and I noticed then more traction rolling and the rear end being loose. So I am thinking of course don't have my weight balanced on the vehicle.
Anyway, basically when coming around the large sweeper the vehicle if I let off the throttle at all during the turn it would whip around the rear end then traction roll.
Initially I was thinking of stiffening up the front end as I have a lot of steering now for the rest of the track, and I also get chattering in the rear during turns as the car goes around turns.
As a side note, I am running swaybars too.
I can post my setup if that helps, just really need to get rid of the traction rolling
