I'm working on a Paper Helicopter Experiment in school where I'm looking at the deflection angle of the rotors versus the rotational velocity of the copter. I'm having difficulty forming a relationship between the deflection angle and the torque that the helicopter experiences
But how exactly does the upwards drag force resolve into a horizontal torque? I've been drawing some free body diagrams and the only way that I've seen that torque could have been produced was if the blades pushed back on the air with a force equal to the component of drag force parallel to the slant angle of the wings. Is this the reason or is it something else?
Any help much appreciated
By the way if anybody is wondering what a paper helicopter is:

Looks like a sycamore seed.
Thanks
