RE: WACO YMF
I got in the shop tonight and was on the phone with damifino, and the next thing I knew we had talked our way through building the actuator for the incidence linkage. There will be a dedicated servo that drives the link, and will be controlled with the flap channel, and use the rotary knob. The end points on the servo will be limited, since I will only need about 4 degrees of total movement. (six at the outside) Here is the setup, made from F-13B and some 1/8" ply and a 90 degree bellcrank. Dirt simple.
