RE: aileron servo mounting?
With the servo mounted to the hatch as Minnflyer showed, makes things a bit easier. It was particularly nice because you can remove everything with the four screws (one on each corner) to work on the linkage if necessary. Then you can make the adjustments to prevent binds without having to take everything apart to get at the servos. You can do it with everything in your hand before you actually mount the cover with the servo in the wing. Makes things a tad bit easier.
