I'm a beginner at 3D. Ive been flying an ultra stick 40 but does not 3d well. I want to get either a MOJO 40 ARF, Funtana X 50, Showtime 50, or 3d foamy. I have a O.S. .46 AX and was thinking of either buying a O.S. .55 AX, Saito .72, Saito .82, Saito .56 or another engine if I need one. What do you think, if any of these, is the easiest to learn on and durable enough to survive a slow speed crash from a low altitude.

Thanks
