I'm tired of failing servos, it must be my error at this point but I'm not sure how riding in an open field with no jumps or anything but 5 have failed. Two broke teeth two more just lost power and and one big savox died as well so what is your thoughts for overkill and doing two S9020 for my Mt pro? What all will be needed for the upgrade? I have the killer bee battery comming and a Bec for my receiver.
