Your also going to have to find the appropriate size pusher prop for that rear engine.Both engines will be turning the same direction (C.C.W)when viewed from the front of each engine.Your probably going to have to use a CH type ignition system on these engines and do away with the magneto because like was mentioned already,I don't think your going to have the cowl clearance,unless you set back the firewalls a bit and use a much longer prop hub adapter
.They would have to be custom made no doubt.Any other way would have the cowls so chopped and modified,it would just end up looking dorky.
I'll be using electronic ignition to try and save weight.
I know that you can make a Ryobi run backwards if you just put the hall sensor on the opposite side and flip it backwards. But, thats only because it's a reed induction through the backplate. I don't think you can reverse the operation of a piston ported engine--I could be wrong.
I really don't see a need to run 1 engine reversed on this plane. With both engines running in the normal direction--torque will be canceled out. Thats the beauty of an inline twin.
I'm checking into the threads that discuss gas/glow fuel combination--where the engine is run on a glow plug and no magneto or coil. Thats would be light, and no magneto to interfere with the cowls. I'd prefer C&H and run regular gas 40:1 mix--but I'll do a gas/glow hybrid if I have too.
