This was a biplane we built years ago and launched. The motor is powered by a 9v battery and there are vertical balsa supports all the way down the wing to give it the correct shape to allow the Bernoulli Principle to create lift. Unfortunately, the battery was too heavy to allow the plane to launch off the ground.

you need some left rudder to counter-act the torque given by the motor/prop. but it definitely looks air worthy.
