Re: Kitfox Model 7
Guys,
This was the factory standard design when the S7 was first created.
The early S7's had manual trim tabs on the elevator rather than the electric jackscrew on the HS.
The trim control is shown in the cockpit console as a lever and it has a friction lock to establish the correct amount of "hold" on the trim.
On these aircraft, the jackscrew was replaced with a tube which has rod ends on the top and bottom - the rod ends are adjusted for rigging, not trim, and the slot you see is approximately half the depth of the slot on the KF with the electric jackscrew. The HS is fixed/does not move on this version. The slot only serves to slip the tail access plates onto each side. The original build manual shows a filler plate for this slot but most builders left this off.
