I have used the aero-works servo extension connections - very light, easy to use and very secure. Thanks for the input on the servo on the wing. The 'side' mount with just the servo arm extending from the wing surface should be very clean. Yes, when I get home tonight I will send you the products I used. I think it was .75 oz weight cloth and two part finishing epoxy, but can't remember the brand name. Will send it tonight.
