here's the retract gear setup, all in the wing for ease, so I only have to plug in the servo wire, instead of 2 quick-connects, which have the chance of leaking. you can also see on the aileron lead the number marker, salvaged off of an old electrical panel i de-commisioned. #1 for reciever channel #1, the retract lead is marked #6, but it's blue and harder to see. the little plastic numbers can probably be found at an electrical equipment wholesaler/supplier. the servo and valve are mounted to the supplied lite-ply plate, and a lite ply rail with balsa support is ca'd to the rib. the air cylinder is held down by the plate and firm by soft foam.

the directions for the air-valve recommended a solid piece of push-rod, 2 chunks of inner snake, some fuel tubing and 3 wheel colars. i just used a piece of pushrod, 2 chunks of goldenrod inner, and a length of 2-56 all thread. the pushrod goes to the first piece of goldenrod inner, which is adjusted for length with the servo "down" to push the cylinder just to the edge of the valve body, the all thread is threaded into the first piece of inner, and cut off with 1/2" to spare, the servo is put "up", then the second piece of inner is threaded on to push the valve cylinder to the other side of the valve body. check several times for correct alignment and voila! same function, 1/3 the parts count (and I would guess half of the setup time)
