I have a pretty small trim tab, maybe 3"x6", with about 25 degrees of
deflection in each direction. It's way more than I need for normal flight
throughout the weight range, but when the flaps are down, it's not enough to
counteract the nose down pitching moment. It doesn't really bother me, an
Last night I was working on my elevator trim tab. It is the stock size
and location and looks like I will get between 20 & 25 degrees of
deflection each way. Is this enough?
Thanks in advance,

If your CG is correct, th
Your trim indicator signal is either at a D C level, or at a low audio
frequency. The radio frequency is much higher, and is being rectified to a D C
signal at the input of the indicator.
I would suggest that you put a 0.01 microfarad disc capacitor across the input
wires. It will bypass th

tab. With the manual lever you can tell by the position of the handle.
The sensor/indicator will be the tricky part!
