what size battery you using 7.2 or nimh and stick with the stock pinion gear i use the stock pinion gear with a 5.5turn brushless motor and a 78 spur gear and slipper pads off a rb5 and there no heat problems at all there a nice truck but diffrent to the madrat the chassis longer but a very good truck i got 1 myself

did any of you do anything with the diff apart from putting bearings in

put b4 diff balls in the diff and put grease init and it will run smooth as hell. and change the spur gear and slipper pads to rb5 koysho . the spur gear are shaped like a egg on the macnum. and get a carbon tplate and and some alloy rear pin holders
