Most MonoPhan units have a stall problem at low attack angles due to lack of lift. The purpose of this test is to come up with a design which will reduce the stall angle and raise the center of lateral resistance to be able to do some acrobatics. I had units with this kind of small wings in the past. This is a revisit of the same concept with a new unit. The purpose is not support horizontal flight, as these wings are too small to do that. It is to improve the aerodynamics of the unit.
Wing 1: Simple "duh" design just to see how the unit will respond. Vertical flight is good and she transitions to forward flight nicely but completely loses it transitioning back to hover, with Center of lateral resistance too high, the unit gets slammed with air due to high speed and quick transition.
Wing 2 (2min mark): My super creative and smart friend Jamie Griffin's design. It is well balanced in transitioning back to hover. Definitely a better balance. However, due to me forgetting some old lessons and not taking precautions for managing the tilt angle she lost it and crashed. Thankfully no major damage. Will make necessary adjustments and re-try.
