I finshed the trimtab tonight. I wasn’t missing much, only had to matchdrill the hinges and rivet it all together.

After matchdrilling the hinges, I had to modify one of my bucking bars to reach the rivets. After that, riveting the hinge to the trimtab was easy.

Then I continued with the elevator part…

And after installing some blindrivets in the ends, the trimtab is done!!
Only need to roll the leading edges and install the trimtab servo now.
