I'm not responding to the poll at this time, because I have not done the fiberglass gear fairings (legs, wheel pants, or intersections). I'm also still tweaking my full flaps setting, as a compromise between having full flaps available and not having the VP-X call a flaps fault when I go to full flaps and the PH Aviation actuator stops moving before the flaps are measured at the position number I want. But in ~120 hours of flying, I will say the following about trim in my taildragger RV-14:
Just like the RV-14 taildragger factory demonstrator that I got transition training in, there is a big pitch trim change between half and full flaps, to maintain speed. I have also noticed
The last bit of flaps movement appears to be the greatest rate of pitch trim change. I have noticed that my trim position at touchdown is noticeably backed off with the flaps set to stop a little short of full down, compared with where it was when the flaps were going to full down travel.
The trim is quite a ways forward in cruise, but not to the end of travel.
If I notice big changes when I do the fiberglass work, I'll try to remember to report back here. But those are my observations in RV-14 trim behavior so far.
