Randy, Can you provide some more details on the flap modification? That might explain some of the dirty stall speed differences. I am curious about the wing trailing edge and flap leading edge interface. All, Just for reference, given an indicated stall of 61 KIAS at 1,600 lb: KIAS, Load factor 61 1.0 70 1.3 80 1.7 90 2.2 100 2.7 weight, stall speed (KIAS) 1600 61.0 1800 64.7 2000 72.3 If your indicated stall speed is higher, everything scales up for stall at 72 KIAS KIAS, load factor 72 1.0 80 1.2 90 1.6 100 1.9 Notes that
stall speed varies by quite a bit from super-light (1 person, low fuel, no baggage) to heavy (2 people, full gas, lots of bags) Chris Zavatson N91CZ 360std On Tuesday, October 22, 2013 8:17 AM, George Shattuck <gws37@plantationcable.net> wrote:
Over the years I have made it a practice to turn
base with half flap and 100 kts. or so, then turning final at roughly 90 to
95 kts. When I have the runway made down comes full flap, ease the power
and start the flair so that at 1/8 inch off the runway the airplane stops flying
and squeeks on. My stall speed with gear and half flap is in the low 60's
but I don't like to get near that speed. I suppose it is my old Navy
habits but I keep it close in on the downwind and base. There is no sense
to being wide abeam and strung out on a long final.
On take off I keep the nose down and cleaned up I'm
near 135 to 140 kts by the end of the runway (5000"), the up and off I
go.

The only stall speed I know for my airplane is 61kias in the
landing config, power off. That's the only stall I've performed or intended to
perform. Not sure why mine is 6-7kts lower than yours, unless you're using
KCAS?
Small tail, 40 flaps here.
