My constant speed prop oscillates a little on take off? Why and how to fix?
I put in new engine, rebuilt the prop governor, and when it was all back together and flying I notice my prop speed fluctuates a little on take off. Once I pull it back a little it stops fluctuating. What I mean by fluctuates or oscillates is it speeds up and slows down a little. A little is 50 to 100 RPM. Not a lot. It didn't do this before engine change.
So anybody know about this? I'm thinking I didn't get the prop cable tight enough and the prop may be at top speed on take off and the governor is kicking in to slow it down, or a loose cable is letting the prop change itself.
Any other ideas?
thanks
