[/b] I read somewhere to attach the lower aileron to the upper aileron in such a way that the upper moves the same amount as the lower. If you hook them up one way you get a little differential in the upper. I don't want that. I want equal movement in both.
Requesting the proper way. Somebody good in geometry.

As long as they are both at the centre of the trailing edge of the ail. they will have the same throw.
Tried for my kamikazi pilots licence. Flunked the test.

When you do the first flights keep an eye (ear?) open for any indication of aileron flutter if you are using two servos and connecting rods to the top ailerons.
The best way but not the simplest to avoid any problems is to use a computer radio and four servos to drive the ailerons,if at all possible IMO.

Hi Roger,

I try for trailing edge to trailing edge if at all possible (as Flypaper suggested). If it's not too late, splice a length of basswood into the trailing edge to mount a ball link to the trailing edge. With this setup, you can adjust the links in/out to move the pivot point in or out to accomodate small differences in geometry due to aileron chord or wing sweep while the ball link will accomodate any non-linear movement.

Hope this helps .... what are you building?

If you wish to use the 4 servos and you do not have a computer radio that will do the job you can use the JR Matchbox. This allows independent adjustment for up to 4 servos but control from one channel.
