Correct, that would be so much easier & cheaper. As for the supermaxx, you need to turn the tranny around otherwise it will run backwards like that! The esc motor wires are just long enough to mount the esc right infront the gear cover, but the sensor wires to the motor are a bit shorter, so you have to kinda run them up over the top to reach the esc from the motor:-
Obviously I have a different chassis but thats basically the neatest way to do it- just tie them down to prevent any nasty accidents from loose wires.
