Thanks for all the replies, I have decided to mount a servo in each wing. Now the nearest one to the size I think I need is a Futaba S3107 the dimensions are .9"X.4"X.8" the total width of my wing is 7 3/4" and the width of the aileron is
2 1/4w X 9 1/2 L my wing at the thickest point is 1 1/16" so the distance from servo to the control horn on the aileron would be some where between 2 1/2 to 3". I've seen a lot of guys just glue the servo in flat ways and drop the control arm out the bottom of the wing. Now this brings another question to mind. Will a standard control arm be long enough to drop out the bottom of the wing? And thanks again for everyone's replies and consideration.Raymond
