 Posted: Wed Jul 09, 2008 9:27 pm Post subject: Aileron Trim and wing leveler question |
 |
|
RV builders who've installed manual aileron trim (the little lever between
the seats with the springs down to the control stick pushrod heim joint
bolt). I built the airplane with this mechanism but forgot to install it
when I assembled the control column, sticks and pushrod tubes. After
noticing my error and dragging out the parts I noticed that the trim lever
relys on the clamping force of a plastic block around the trim lever shaft.
This got me to wondering if the drag from the trim system would adversely
affect the operation of the autopilot (EZ Pilot). Anyone have experience
with manual aileron trim interfering with the operation of your wing
leveler? Or...is this a non issue? Thanks.

It's a non-issue. The system only puts a little pre-load on the aileron controls via the springs. You won't feel it in the stick and the A/P won't care. In fact, I find the my wing leveler (Naviad) works just a little better when it has to fight the trim a little bit. Not sure about the Trio, but I'd love to swap out the Navaid and find out!
I did replace the stock springs with much longer ones that ran most of the length beteen the trim arm and the control stick, attached by very short pieces of safety wire at the ends.

I don't know about the EZ Pilot but mine works just fine with my Navaid and works perfectly when hand flying to relieve aileron stick force due to fuel burn or passenger weight. I did find that I had to set the friction pretty high to prevent creeping but once that was adjusted it has worked just fine.
