I’m a bit disappointed in the company I bought it from though. The instructions for gluing support structures onto wing surfaces say that when you are cutting away the plastic film on the wing surface so you have a clean place to glue to, you have to be careful not to cut through the plastic film and into the wood underneath because it’s extrememly then and cutting it seriously decreases the structural strength of the wood. Well, as I’m working on the aileron servo mount problem, I remove the reinforcing bracket they glued into place on the underside of the wing for me to mount the servo to, and I find out as I’m cutting away plastic film to increase the size of the support bracket that THEY cut through the wing surface when they originally cut back on the film to put their original bracket in place. So, that explains why the servo broke loose from the mount. Well, I fixed it by gluing support brackets on the bottom and top sides of the wing surface skin, with both sides larger than the original support bracket size so they encompass unbroken wood all around the outer edges (which is all that really matters when it comes to shear strength of the bracket area, the cut and broken portion inside the wood sandwich is effectively rendered moot by the larger bracket size).

Anyway, that’s why my next plane isn’t going to be a mostly pre-built plane, it’s a build it from scratch, we give you the wood and the plans, type affair. I take care to build things right. Someone making $6/hour and not flying the plane when it’s done doesn’t.
