Thanks for the replies

I suppose for 3D'ing it'd be better for the plane to be overpowered than underpowered... What size prop would best suit the saito 100 for what i want it to do...? No one at my club does 3D flying but i saw people doing it when i was over in england during the summer. It's so cool. I'm gonna have to learn it the hard way tho (at a nice height of course) cause there's no one to show me how it's done. This is why i dunno what prop would be best for 3D'ing...
