I have an MVVS .91 with BCM Pitts on a 66" Extra. The ability of this engine to swing a rather large prop (APC15x8) with ease makes me think it would absolutley rock with a lower pitch prop on a 3D airplane. I'm going to move the engine into something more 3D-able and am trying to figure out which airplane to get, the SIG 3D mayhem looks promising.
