RE: F-15 aileron setup
I fly mine with the same set up, powered with a Jet Central Super Eagle, fly the piss out of it and have about 100 flights on it so far with great results. You will be surprised that even though the ailerons are small...it does not take much deflection to roll it around.
Also, mine is pretty fast for what it is (150 MPH) so it ain't that slow.
