By 9 o'clock, I mean that the trim control handle, when looking at it from the center of the cockpit, is in the 9 o'clock position, i.e., handle extending aft. I'm not certain if that is the result of the factory instructions or a previous owner's adjustments. The result, in our case, is that this is full nose up trim and yields about 70 mph with power set for straight and level flight. The only disadvantage I see in this is that you can't trim it to slower flight for final approach, but as I said before, the control forces are so light that you don't notice the need for slight back pressure to slow it down to flare and touch down speed. The advantage is that you can't trim it to stall speed with a load factor of 1. In an emergency situation, if the trim is set in this position, then relaxing the elevator will give you a safe AOA which is very close to Vy. On the other end of the speed range, 75% cruise power in our 80 hp Allegro, the trim control handle is set to about 5-5:30 o'clock. There is plenty of trim control range and it easy to set precisely the trimmed AOA for any speed above 70 mph. If you want the full nose up trim to be slower, that is your choice, of course.
