I have a 3 CH, 2 axis foam parkflyer which I should like to upgrade to 3 axis by the addition of ailerons. I really need help on almost all of the conversion ie. what size should the ailerons be (I believe about 20% chord)? When I cut out aileron do I need to add stiffen the rear part of wing in which aileron sits? How best do I hinge the ailerons given a 40 " span?. How do I run out the control wires to the servo(s)? (Should I just route out a slot , put in a guide tube and refill).
Should I use 1 servo and long control rods to each aileron or one servo in each wing?
Any other suggestions and guidance would be appreciated
