Brief Description: Elevator and rudder mounting
|
|
I spent quite a lot of time perfecting the elevator "up" stops today, mostly by filing away the stop material bit by bit, and checking & re-checking the elevator angle as I went. I set the maximum up angle at 27.5 degrees, right in the center of Van's 25-30 specification. The slots I made will be cleaned up later, after the horizontal stab has been removed.
The elevator down-angle will have to be set a bit differently from the plans, since the elevator horns don't even touch the stop at their maximum specified angle. I think I'll end up fastening "stop shims" onto the horns themselves.
With the elevators in trail, I marked the left horn for drilling the pushrod attach hole. (It's the aft-most horn, so it will be the "master" for the hole position.)
Oh, and I mounted the rudder, too. I had to make a slight adjustment of the bottom rod end, but once it was mounted, the rudder moved as smooth as glass. So far, I coulndn't be happier wth the alignment of the tail section components.

The elevator "up" stops. They don't match because the horns don't exactly match.

All the tail feathers, on the airplane for the first time!
