Rubber Band Powered CFI Instructional Airplane.
Awesome for demonstrating concrete explanations to students, including Left Turning Tendencies, Flight Maneuvers, and Ground Maneuvers.
The model can even be used to demonstrate CG and Center of Pressure by sliding the wing forward and aft and letting the model fly! (So far the flying record is about 120′ across the ramp!)
Model is approximately 12″ wide (wingspan).
