A workmate of mine has decided to build an aircraft with the following description:-

28" wingspan
36" chord
6" camber.
The airfoil is flat bottomed.
Weight is expected to be 2.2 lbs.
It has a semicircular cutout at the trailing edge effectively making it twin boom, with 2 vertical fins and a high tailplane and elevator on top, the main lifting surface at the tips is angled about 45 degrees downward and inward.
Construction will be completely of polystyrene ( except for engine bearers etc )
It will be powered by an OS LA 25. Covering will most likely be coloured parcel tape or similar.
He intends to use rudder/elevator only, and expects that it will be able to fly slowly, and be able to hover at low throttle settings with an extremely high angle of attack.

I'm not so sure about all this, so I would appreciate any comments (or advice) regarding this project.
