Elevator Horn

[CHARLES DEBOER]

Mr Bill asked for a couple of pictures of my push rod elevator horn attachment.  I couldn't make it work on the PM reply.  See below.

Thanks, exactly what I was looking for.

if you are using adel clamps on the pushrod you can remove the stop.  also remove the top of the control horn

Hi guys.

Just a word of warning.  It appears the elevator horn has been built the way I did mine.  Drilling the lightening holes weakened the area that is closest to the weld sufficiently that mine cracked with only a little flexing.  I went back and welded another .035" horn on top as a fix.  I would recommend NOT building the elevator control horn the way I originally did mine.  An inflight failure of this item would have dire results.

long passed the question time frame, but a 1/4" flange on the rudder horn has immense strength and flex stopping attributes.

Here's one with a flange, a large welding area, and control cable/rod holes aligned with the hinge line.
