what kind of trim control does a KR have? Some KR
folks have installed various trim devices and even auto-pilots with some
success, so not sure where this discussion should go.
I don't recall anyone addressing your question. These are the types of
things learned at a KR Gathering with a chance to actually look at
options live and in person. Every builder should attend.
I'm using the "Ray Allen" servo or whatever it is called now. I started
with a cable system to a tab on the elevator but didn't like amount of
free play in the tab. I bit the bullet and ordered the "Ray Allen" unit
and installed it in the elevator with a very short push rod. I ran the
wires to the instrument panel for the rocker switch. The indicator
burned out in a very short time but I never repaired it as I don't look
at or reference it anyway. My switch is actually mounted below the
panel on the sidewall out of site.
Others use bungees or springs attached to the control system with some
means of changing the tension on the stick. Photos can be seen at
If you look at the center left, past the throttle and below what I once
used for a GPS before switching to IFLY and a 10 inch tablet you can see
my trim switch and indicator. Now you know why I never bothered to fix
the indicator, I can't see it. That is never a problem.
