The driver was one of our top club members that couldnt get his car to arm, so for him a kit version would be the better choice. After playing with some radio settings we got the steering opened up a bit, its still kinda slow (7950) so I dont know if its the BEC. The esc still has that cogging when trying to finesse at low throttle, but the motors got a ton of power though! Chassis wise it looked like it was performing good and was doing well on very challenging courses. For those just starting the RTR will be just fine until they feel the need to upgrade, for a veteran I'd suggest going the kit route. Its going to remain unchanged till after the Championships, then I'll start swapping electronics and see how much improvement and what each upgrade does.
