I've upgraded my Raptor G2 with a brushless motor and esc. plus a new receiver. However, when I hook the battery up and try to program the esc, the helo does not do a thing. Even the gyro does not come on. The receiver is FM along with the original tx that came with the Raptor. The crystals are new, so I don't know what's wrong. Any advice??? Could the new receiver be bad?
