after i install the clutch spring from traxxas 4146x, and using stock clutchbell. the tsunami is very hard to move, seems like very hard to engage. give it almost full throttle, but it only runs like give a little bit throttle. is the spring too hard to engage? or do i have to change clutchbell to hpi 3 piece too? or i can just use stock steel one. something else wrong with my tsunami
sounds to me like your gears are meshed too tightly if i understand what your saying, there should be a little bit of play between the clutch bell and the spur gears.
