Well said Mike. I have been travelling a lot and have followed this
discussion but have not been able to offer my input. I have done
several stalls. Clean, dirty, power on, power off. All at high
altitude. Never have I had anything but a very gentle break preceded by
a slight buffet. I have had very small loss of altitude and easy
recovery. I have practiced landings at 85 kts, 80 kts, 75 kts, 70 kts.
No flaps, 1/2 flaps, full flaps. For me, my ES, does best with 82 kts
over the fence and 75 kts at flare, Full Flaps. Touch down is almost
unnoticable at 68-65 kts. My stall speed in this configuration is 58
kts.
On takeoff I rotate at 72 kts. Accelerate to 90 kts climb 200 ft
accelerate to 140 kts and continue my climb at 900 fpm to altitude.
I have wings that had 2.0 plus degrees difference in incidence. We must
remember that the tools we have to measure this are crude at best.
Basically a blueprint that is transferred to a template (1/2" plywood)
that is cut with a jig saw. After placing the template on the wing at
the appropriate BL and comparing the two wings. The airplane is leveled
using any variety of means. Mine was using a transit. Who's to say
what the real difference is other than that they are different. My
airplane rolled to the right at 10/sec. After installing the banana
bracket eccentrics (I raised the right wing incidence and lowered the
left wing incidence) the roll was eliminated.
I feel Tim Ong did a great job in supporting this problem.
As a note, at the same time that I was having this problem Mark Manke
had just solved the identical problem on a IV P (Turbine I think). He
used the eccentric solution as well.
