Maiden Flight
I finished assembling the plane over the weekend and took it to training night on Tuesday. We ended up making several servo adjustments before cranking it up, and this just reinforced to me the wisdom of getting someone with a lot of experience to help you with the plane. I thought the servos were all set properly, but they showed me several things that needed adjustment. We did have trouble with the throttle linkage but finally got it where it would come back to idle.
One of the instructors took it up, and if flew just great. A couple of clicks of down elevator was all it needed for hands free at mid-throttle. When he landed the plane came back to idle, but wouldn''t shut down. Turns out there is a small amount of interference between the push rod and the engine mount, enough the the servo shifted a bit at zero throttle, and the trim would not close off the barrel. The servo had moved enough back and forth to strip the threads on the wood, and the screws will not tighten. Much to my disappointment we weren''t able to fly it again, so I didn''t get any time on the box.
I''m going to epoxy some thin wood under the servo mounting holes and remount the servo with slightly larger mounting screws. As a beginner I didn''t know to CA the holes before using them and the manual didn''t mention it. So......while I''m at it I''m going to pull all the servos and CA all the holes. I''ve also got to add a bit more offset to the pushrod between the firewall and engine to remeove the interference. Should have it ready to go again this weekend, but it looks like the weather probably won''t cooperate.
It was a kick to see it flying, though. It''s not like I built it from a kit, but I did put it together.
