2 Different Wings 1 Airplane Test Flight
In this video I will do an experiment with using two different wings on the same airplane fuselage. This is a 5 ounce foam board flyer. The first wing is a flat, no airfoil, 3/16 inch foam board wing with 0.5 inch dihedral and a slight amount of positive incidence. The model airplane has three channels of control with rudder, elevator and throttle.
The second wing is an airfoil shape, same chord and dihedral. I use rubber bands to keep the wings in place.
Note that with the first iteration of this model, testing out a flat wing with zero dihedral, I used ailerons for roll control. For this version, with rudder control, I added a half inch of dihedral which seemed to work fine.
The plane few quite well with both wings. Interestingly enough, the flat wing seemed to handle a bit better. The model needed no trim and was smooth and responsive during the model airplane test flight. My conclusions are that a flat, no airfoil wing can fly just fine in a lighter weight model.
