E-MAXX Transmision question

[squeeforever]

what i did to reduce weight and rotating mass was take out the 1st speed idler, left the shart, jb welded the shifter engager thingy to the second speed gear, and then shaved off all the teeth and stuff on the 1st speed gear to were its just a couple of bearings and a peice of plastic to hold them in and use it as a spacer, and removed the shifter fork. this takes out ALOT of the slack in there. youll notice what slack i am talking about if you turn the spur while is sitting still. that slack is in the shifter engager thingy and the gear.
