Did a bit of reconfiguration of the set up, lost the fan and relocated the esc to the lower level, had to resolder just one plug and replace it at an angle (orange wire) also swapped sides with the receiver... some pics below... need to think about the oil used in the diff as the car is coming to a halt to quickly when the radio stick is released to neutral - it's not too sharp a stop but it would be better if the car coasted for a bit longer to make cornering easier - I have checked the pinion and spur and it's not too tight - there is no binding and I have checked the esc config and that seems in order (I have zero drag brake set) so I can only imagine that the diff oil is too thick? I used the oil that came with the kit and it was really thick! Any ideas of what oil to use carpet racing would be welcome...
