I did that one time. It did not work out so good. the 1st thing is that you have to lock down the prop hub so it will not spin off. A pusher prop does not seem to work as well. I do not know why but the power is not the same on the pusher. I ran a twin like that for about 8 flights. I swiched it back and did not see much in the way the plane proformed. So in a way It is a lot of work to not get much out of it. But that is just the way i see it.
