I said it before and I'll say it again...Jim Bede.....Preston Tucker....the guy who has the commuter plane that is supposed to be in everymans garage.
It won't work just because someone is good with autocad.
BTW- during WWI the engines in most planes spun with the prop. (rotary configuration) Later, they fixed the crankcase to the firewall and then only the prop spun (radial configuration).
Do I get an actuator?
