I added the trim tab to s/n 752 back in 2002 at the insistence of my A&P/IA who said it was required because of the engine that had been installed (I don't have the exact note at hand from the Type Data Certificate).
In any event I purchased the kit from SkyPort and did the work under the watchful eye of my A&P/IA (he make no money telling me I had to do this). Using the instructions with the kit I added the trim tab to my existing elevator (an exercise in aluminum working), and added the trim cable and control. The elevator work was easy compared to adding the trim cable. I had to remove the horizontal stabilizer in order to properly run the cable within it. It was several months of weekend work, but it was worth it (in my opinion) as I noticed much better trim control than with the down load from a spring on the elevator.

However, I do not have the elevator with the trim tab, and would have to also add the cable and control for the trim tab. Costs for all that would be about $1300 for the increase. I am questioning if it is actually worth that much to me. I have two questions: One, someone said once that a trim tab could be added to my elevator, has anyone done this recently or has an old elevator that the tab has been added to on their plane? Second, how much weight does that add to my plane? Obviously I would not gain the entire 60 lbs, since the hinge, tab, and control would eat up some of the 60 lbs.
