RV-9 Electric trim tab question

[Jrskygod]

I need to find out what the dimensions are to set the linkage on my elevator trim tab or where I might find them. The numbers in degrees deflection or probably easier yet in inches at the rear edge of the tab would be awesome. Thanks

If you have an electric trim motor, set its position to mid travel using a 12 volt supply. You can confirm its mid position by measuring the resistance of the position wire pair or your indicator if installed. Then set the trim tab to the neutral position and play with the linkage length until the trim tab control horn and rod end hole line up. You will find that you use a very small amount of trim tab movement in flight and the indicated position means a lot less than what the stick is telling you.

That's how I set mine. I connected all the parts and used a little 9V battery. It worked great and felt good to see something work!
