Flight Report:
The Qhor-Bipe flies very slow and predictable. It does a nice tight loop. Rolls are descent but a bit in barrel form due to the fact that there are only ailerons on the bottom wing, so the top wing does not want to roll along the same axis. Glides are descent on engine outs due to the double wing area, but you still have to make sure the nose is pointed down and flare out close to the ground. The plane can also fly very slow with its nose high at a good angle of attack, almost pizza box style.
