Don, what about split ailerons/flaps, like on the hangar9 utlrastick? Split the flaps down, the ailerons up, and use that for braking? Would you have to worry about a noise increase on going to a larger prop under accelleration? (the new IMAC sound judging)

Also, are there any people using variable pitch prop/hub combos on the large scale planes? I would be concerned that the stresses on the prop and hub would cause it to throw a blade, which would be a very very bad thing. It's something that a couple of fliers and I have batted around the feasibility of. Imagine the AA or freestyle routine you could do with the ability to feather the prop, or even get a little bit if negative pitch. Pull a 45 upline, head into a lomchevack, kill the pitch, and let the plane move on the 45 upline backwards a few feet (aka Wayne Handley sp? and the turbo raven). Using smoke to enhance the effect. Or take it to the total extreme, and go from an upright to inverted hover(tail high). Could lead to a whole new set of maneuvers, like the spinner touch .Amazing what you think of at 3:30 in the morning when you cant sleep.

BTW, how is your new focus doing, with the dual sets of wing panels?
