For use with the Morphis Kit, 16mm & 19mm electric motor set outs have been allowed for. The on board generator position is designed to be in constant drive even when the engine is at idle. Generator position design does not interfere with either the top start or the bottom pull start. The mounting plate is part of your top engine mount within the kit. No parasitic losses to momentum during autorotations.The design position is in line with the CG line (center of gravity) for future heavier starter gearing & electric starter motor option for scale builders.
