That said. If the wheels are free spinning, then 1lb of thrust should keep it moving forward on the treadmill no matter what the speed is right? As long as there is a counteracting force, no matter how small, the plane would at least stay in place if not move forward. Just a thought.
However much power it takes for a plane to move is what it takes to overcome the conveyor...you've seen the commercials where the full size pickup tows the plane right? OH, or better yet...what about those little propane carts that tow planes you see all over the tarmac at an airport....that's how much power/thrust it takes to move forward on the conveyor.
