i started it with the starter...... spinning it clockwise. taxied around, took off!!!!!!for it to push a LOT of air forward (enough to push the plane in reverse) it would also have to be a reverse pitched prop.

If you look at a prop, spin it slowly backwards, you will see ( at least on a 7.5" pitch) that it still screws into the air.


i dont have the answers, just the experiences.
