RE: Scratch building 105" W/S Super connie L-1049 G
According to George...the Futaba sailboat servo has worked out perfectly.
These are pretty easily found and mounting the flap using either arrow
shafts or carbon fiber rod with stops to force the flap tilt as the push rod
continues rearward is about as simple as it could get...as you can see in
the posts describing more complex systems.
I view flaps with respect to your project as a cosmetic feature and not so
much an element of control. I'm simply guessing, but 20 degrees on that
wing should have a decent effect on your landing approach.
The fiber glass arrow shafts will slip over an aluminum shaft as well for a
good slip fit that would need minimum lubrication.
