Does anyone know the best way to fix this?
I know the problem. I have used some thin CA to thicken the elevator carbon tube joiner when it wears and get wobbly. This is maybe not enough if you plane has a fault in the aluminum bearing.
One possibility is using Xolorer large elevator. Bearing works just perfect if you cut a length from Aspire joiner tube and sand the opening just a little bit. Then lightly glue the carbot bit to elevator fin bearing (you may have to replace this when it wears out). Xplorer elevator needs some dremelling to fit around Aspire fin, but this is just a 20 min job.
I like to use Xplorer elevator on Aspire because it gives more accurate trimming and very positive elevator response with smaller movements (Aspire elevator has way too thick profile). I also firmly believe that original Aspire elevator has more drag.
