I agree, but I didn't want to go into that detail.

I forgot another aspect: Flying such a thing will be much different to flying F3A, and I don't even mean the instrument flying using the control system in the FPV. It has been said as well, a stable airplane is required since even if it can be flown "IFR" it is much workload. And why use an expensive and (a bit) heavy autopilot when a stable plane flies on its own, anyway. Like in the old days, it should be trimmed for a good power-off glide and then the drive set up (downthrust) for best climb.

The plane could even have a polyhedral wing without ailerons. There are such 5 meter rudder-elevator gliders! And there's an idea to place the two halves of the inverted V-tail seperately quite far outbords on booms attached to the wings. This way they have a rudder and aileron effect at the same time. Here are pictures. Not exactly a pusher but you get the idea.
