My O-360 powered -9 taildragger spinning a fixed pitch Catto prop will cruise right at 175 knots at 8,000 feet density altitude at 75% power.
On Christmas day I spent some time exploring the lower end of the performance spectrum.
Short field:
Within 900' from the end of a runway on a no wind 60?F day, not my touchdown point, I was able to land and take off again. That was land, stop, raise the flaps, adjust the trim and take off in less than 900 feet. Since I floated past the end of the runway, I absolutely believe Van's numbers.
Optimal cruise:
On that same flight I thought I would see what my optimal extended range speed would be.
It turns out that 40% power gives me 135 knots running while burning 4.8 GPH LoP.
This works out to 28 GPH gives me a range of over 1000 NM.
What numbers are the rest of you seeing?
