Pitch trim stiffened

The weather is crappy, not going anywhere any time soon so pulled the canard off to access the paddle board pitch spring that's riveted to the elevator torque tube.

 The pitch trim is okay at 160-ish KTAS but at WOT going 180+, the stick needed my help to stay in level flight otherwise it would climb.    I added two plies of full length UNI and a little 1" BID at the actuator end to keep the spring's UNI from splitting and cracking.

I'll work on some other items while the epoxy cures.


----update ---  The AP can hold altitude at WOT now.   The pitch stick is noticeably stiffer, but I think the only other option than stiffening the spring would be to change the canard incidence.
