As I noted in your other thread, I am using micro metal gear servos(in the ailerons) and now have over 40 flights on the plane. No issues whatsoever with the strength. I have been flying the plane hardmy favorite move is a blender into an inverted flat spin, then into a hover. I used a 9" extension on the aileron servos on the top wing, which feed thru the fiberglass wing stanchion. I then use a Y harness to connect both right top & bottom and left top and bottom servos inside the fuse. I use dual aileron mixing just as if there were one wing and the Y connects the top and bottom wing.

BTW, the plane flies very nice "free flight". Yesterday, my battery came loose during flight, and after a few minutes: whoops, there goes the battery out the battery hatch. Since I'm just using the BEC from the speed control, I had no control. Plane was fortunately upright, and landed power off at about a 30 degree angle. Tore the gear off, but didn't even brake the prop! Didn't tear up the fuse much at all; should be able to glue the gear plate right back in. Looking forward to many more flights with this plane!
