After finding a good source on the Matronics listserve for flap actuators, I went ahead and orderered one. I know I'm not going to need it for a while, but I'm trying to stockpile some of the more expensive parts when I find a good deal. The cockpit control buttons will allow me to have 3 positions - no flaps, 1/2, and full. Pretty cool. Now all I have to do is build an airplane to go with it.
