Yes it will take off. Planes gain lift from air speed not ground speed. The prop would still move the plane forward due to the thrust produced by the prop. The speed of the convayor would only make the wheels thurn faster. If this were to be a real life situation i would hate to be the pilot tring it due to the fact of trying to control the plane until it gained enough speed to gian flight. Too much brake on either pedal would end up in a bad situation.
