YES! TE = Trailing Edge, LE = Leading Edge

Hinge points (made by Robart and Great Planes... I prefer Robart) see the pic for the best description. To install them, simply drill the correct size hole in both parts and glue in (epoxy, hinge glue)

Yes, mini-servos should work but I'd go with something similar to a HS-81 (by Hitec)... the very small HS-55's will probably be too weak. I used standard Futaba servos because I had many available.

You'll want to mix in some 'down' elevator when you drop the flaps - not a lot. I experimented and used about 10 - 15%, I think.

Good luck!
