Flaperon Bracket

This assembly, at the top middle of the bulkhead behind the seats, mounts the two pieces of tubing that extend left and right into the wing roots, to work the flaperons. It looks simple--just four bolts. But it has to be installed correctly, or one tube will stick out farther than the other. We shouldn't have to bear asymmetry, should we?

It's not as easy as it looks. It mounts off center so you have to try both pieces of tubing to get it where it needs to be.  It's not particularly easy to drill the holes but fortunately I'd bought a long drill bit in the appropriate size--5 mm.

The two openings in the gray bulkhead are for levers attached to the ends of the two tubes. The levers connect rather ingeniously to control linkages that come from the dual control sticks and from the flap lever between the seats. The bolt between the two tubes also goes through the hole in the flaperon bracket.
