It would work, though I don't know how well. I would be very interested in hearing test results. When I get more money I'm going to buy a few props to try. There is a Bolly 3-blade 14x5 that I want to try though I think it will be too much of a load on the .82, even with 30%.
Got some pics of your modded Extra?
