Well N56GZ has flown through phase I and out of the coral, now the fun phase. I installed dual electric servos on the elevator trim and have found them to be quite nice, effective, and from all indications working extremely well and safely. At least for my style of landings, with two forward occupants, 2/3 full fuel, and a case of oil in the baggage compartment, I have about 1/4" of up trim (trailing edge) on each tab (and yes, they move and stay well in sync) at landing with full flaps. In cruise, the trim tab is neutral. I do not trim out all stick forces on final, I prefer to have some light back pressure on the stick, so I am sure others will or may have more "up" trim in play than I. These are very big trim tabs for a small and light plane and it is no wonder most find them very sensitive. I may look at testing out one trim tab down the road, appears from my flying of the RV10 a very small fraction of the dual trim tab movement is utilized.
I will start to collect some video of the trim tab, with particular interest in the servo attach bracket, looking for any significant flexing as the trim tab is placed in more demanding positions (simulating a runaway trim etc...). Beefing up the attach plate (as done in the RV14) will be a rather easy task, if needed.
