i see some guys are having problems. it is really dependant of what class or motor you are running. i am using the serpent 84T spur and a 19-20 T pinion, as i am running 3.5T Mod. everything is just easy. 2 motor screws can be accessed easily, and motor is out inseconds with out removing anything else.
i also run speed passion, so a motor change doesnt incurr any soldering either.
i just love how everything is. i wouldnt have it any other way.
but stock....... different story. remove spur, and top deck, ouch........
