I think the short Hatori pipe would be an easy installation. I didn't make any stand for the pipe
mounts, just glued a small piece of plywood inside the pipe tunnel sort of like a washer so the screw
wouldn't pull through the balsa.
I used MK control horns on mine but didn't use the screws that go through the control surface. I used
the ones with the triangular nylon base that angles the control horn over the hinge line and screws to
a triangular piece of plywood that is glued to a recess in the control surface. These are the same kind
that OXAI uses on their airplanes. The Central Hobbies part# is MKD0815. I don't think the ones with
the one screw would be strong enough because the composite control surfaces are hollow.
