i am running the tm4 with centre gear.im using a 80t spur x 8.5t motor 120a speedo all turned down for indoors mostly carpet but some slippy.i tried using a 25t pinion but the motor was getting on the hot side.
motor seems 55.(i know thats not hot but,shell n chassis was all hot)
or is it a air flow prob???
esc 35
i am using 30k oil in the centre too so is that too light and causing spin up?
i have another car setup
9.5t x80t 26 pinion with 50k centre and this runs nice temps
