I am considering the Savage 25 for my first off-road car and i have a few questions about the roto start system. There have been problems mentioned about there been too much torque when starting up, and the result broken parts. Do the benefits outweight the problems associated with the roto start? Also what equipment is needed to get the roto start going (that is not included in the RTR version) e.g batterys, starters ???? :read:
