AGR,


That is the whole caboodle of troubles.

First, a swept wing does not work very well at low subsonic speeds and the swept-back control surfaces are less effective.
As Dr1 wrote, when static; i.e. not flying at full speed, cooling for the engine is marginal at most, since the prop doesn't draw the air straight back, through the engine's cooling fins. A tractor prop will blow the air that way in a 'conventional' plane.

The tank is reversed and mounting it with the clunk at the back will lead to looong fuel lines... Or, if you prefer, mounting it with the clunk forward and have intermittent fuel feed... And the engine goes rich when you pick up the nose and lean, when you pitch it down.

And since the prop blows the air behind all the control surfaces, the amount of control you have at low speed is nil, like in a jet powered (or ducted fan jet) plane. Only at speed do your plane's control surfaces do anything.
With a conventional plane, you got yaw, pitch and (with strip ailerons, some) roll control, even when the plane is standing still (as most 3-D planes fly).


This model would not be my choice, unless I wanted to use a turbine in it and to fly it very briskly.
