Hi all, I am working on a rubber band plane (something like this: http://www.instructables.com/id/Rubber-Band-Powered-Aeroplane/) and I got a question regarding to the physics on these plane. As there is only one propeller and one rubber band, when the rubber band untwist, why doesn’t it rotate the aircraft in the opposite direction of the propeller? Is it because of the moment of inertia of the plane is much larger than the propeller so the resistant is much greater, hence only a minimal rotation that is not really visible to our eyes? But then why real plane need to counteract this torque but these rubber band plane don’t?
Many thanks in advance
