Hi Dave,
As I recall, we get a power off (idle) speed of about 60 knots when our trim is
about centered, as per the LED trim position indicator that came with the kit.
To
the best of my knowledge, we have never flown with the trim on the 'up' (slower
speed) side of the centered trim position. Takeoff position is 2 notches down
on
the trim indicator. With half of our trim range on the (un-explored) slower side
of 60 knots, I have to think there is plenty of range to trim all the way to
stall, if desired.
I'll try to do a little more testing on this hypothesis this weekend.
regards,
Terry Seaver
