Most of my experience is solo at sea level or no more than 600MSL. Book numbers say the aircraft is fully controllable at 46mph. As we know, book numbers are always supposed to be at max gross weight.
I have never run out of elevator while airborne in my airplane. Perhaps the difference is your larger and heavier engine if you are running a 180hp. My prop is also likely lighter, producing a smaller forward moment. I am using a fixed-pitch prop.
Lastly, although my airspeed indicator MAY need calibration, I don't think so, because all of the other numbers are consistent with what one would expect for liftoff, cruise, etc, and I don't have any cover over my pitot tube. I have been very satisfied with my little Cruisair's performance.
I'll talk to you again on the phone soon, Randy, unless I hear from you by e-mail concerning the electric gear components.
