just came across these pictures,
this is a VTOL UAV that seems to be in a pusher setup it order to generate lift.
i think that the controls are with vains located in the propwash, deflection of the vains according to a gyro command will cause stabilized flight.
this is very similar tho the project i am planning.
it seems that there is no special element or feature for cooling the cylinder heads, is it possible to operate the engine is a pusher mode without killing it?
