help, have 3channel elec. sig rascal and would like to add ailerons. Need Help

Thanks

its going to require a different radio, about 1/4 inch of dihedral out of the wing, a servo or two, and a lot of cutting, and more power. its better to leave it as a 3 channel IMO. i did a similar change to a mini telimaster and the ailerons don't do anything!
