there is a plane on ama's plans list called a "joe cat" may 92 i think. this is simular to a bob violet king cat except it is for a .18 ducted fan.
it would be easy to kit bash this into a rear mounted (tractor or forward facing ) engine with a slot for the prop to rotate in simular to a northstar.mount the motor so a conventional starter works. elongate the wings with whatever airfoil floats your boat and go kick some butt.
