Hi Jim,
Well that didnt start out too well. The drill ran off & out through the covering on the top aileron (on the wingtip hinge). Do you know if those drilling alignment jigs work? I might have to get one before I go any further. Seems the drill hits something inside the control surface. It seems the hinges are way too long to me. They only go through a plate about 6-8mm thick, the rest is void. Can they be shortened up a bit so I dont have to drill so deep? I'm using 310's.
Mick
