Wet or sandy astro can be more slippery than a well-groomed dirt track, but the right tyres like Schumacher silvers or Ballistic greens or pinks make a difference for sure.

Thanks for the reply, lots to learn Most of my problems getting round a track are due to my lack of skill. Having talked to some seasoned racers who have run both gear boxes on the rc10b6 and have chosen the dirt version over the lay down gear box for all surfaces but I guess it comes down to driving style and personal preference. I like the thought of getting the motor back as far as possible to get max gyro effect from the motor for rear wheel traction then using slim light weight lipos to keep weight drown and weights up front to get the front traction right in corners?
The nice thing about the KD or KC is which ever you choose they use the same chassis so you can alway get the alternate gear box if you want to convert it from one to the other.
