That's true Larry. Plus my servo will be square to the spar. Then I can
make an easy bracket attaching it to the spar. Thanks guys

This might be a silly question but I can't decide. Should I cut the trim tab
out square with the spar? Or square with the trailing edge? and whatever I
decide I know my ray allen trim tabs servo would have to be square to the tab.?

Hi everyone,
For the longest time I couldn't figure out what? was making my trim indicator
light flicker when I keyed the mike. I did use shielded wire on everything but
noticed I didn't ground it to the panel.

Another source of trim tab installation photos is

perfectly. If you built the horizontal stab per plans to be only 5/8"
thick, I'm not sure if the MAC servo will fit inside either h/s or elevator.

How did you run the wiring through the elevator? Along the back edge of the

Any photos of this?
Also on your site you said you made the tab 3' x 6' instead of 4' x 10',

counteract the nose down pitching moment. It doesn't really bother me, an
Question:
I am installing my trim tab in my Elevator on the Left side so I can open the
