But the authorities of this countries will not share any details. Landing weight will stay at 765kg. My rate of climb is more than good. At 10.000ft I still see 1000ft/min. Stallspeed does not have to be the required 61kt in austria. I = actually have 62kt in my handbook. But I did not test to a full stall 1 or 2 kt lower would be the real stall speed... The plane is certified to CS/VLA (prior JAR/VLA) I hope this details help. I will make some more flights with 0=B0 , -5=B0 and -7=B0 to see the = difference in speed. I will also check the position of my elevator. My incidence of the horizontal is -0.6=B0 and I discovered that my = elevator is not in trail during cruise. I just can't remember if up or = down... As soon as I get this data, I will post it here. After this I can play with more reflex to find out if there is a = difference.

Christian,
Does= your aviation authority have any specific requirements for landing = gear, climb rates, or stall speed?  The airframe was designed with = margins, but would take a good understanding of your local regulations = to know how to advise you on increasing gross = weight.

As to flaps, it would be interesting to = see what you get if you were to sweep through flap settings beyond -7 = degrees.  The lower your lift coefficient is, the more it will = favor additional reflex.
