Time to climb 8500ft
Time to climb from full stop at 900 ft msl to 8500ft msl took 5 minutes and 19 seconds. Oil temp 180deg , CHT 410deg at top of climb. I0360 with hartzel CS prop. Airspeed varied between 105 mph IAS at takeoff to 110 mph TAS at top of climb.

Today I did a straight out climb from my airport to 12.5.
I started counting on the one data row before my airplane lifted off and stopped counting the data after the first row after it broke 8500' (and later 12,500'). From 1083 to 8500' it took me 4 minutes 54 seconds to climb 7418 feet with an average ROC of 1513 FPM. As soon as I took off and cleared the trees, I set the IAS to 103 knots on the autopilot and let it fly. My highest CHT was 410*F, same as Craig. Continuing on to 12,500 it took me a total of 8:21 which worked out to an average ROC of 1367 FPM. Not too bad for a fixed pitch cruise prop. The thing that got me started with this was testing the EIC and some different timing configurations. I dialed the standard P-mag A config Max Advance back one notch (-1.4) and my 8,000' DA all in cruise and leaned for best power was 175 knots. (The SkyView is set to fly slower than that so I had to hand fly it.) My hottest CHT was 379 at those power settings and since I never fly there, I'm pretty happy with what I saw today. |
Nice
Bill, with those performance numbers, you are right there if not better than my CS prop. As a matter of fact, you got me thinking about pulling that heavy CS stuff off and putting that Catto I got hanging on the wall on my -9.
Good grief. I thought I was done with all these changes..... |
Craig, those numbers don't count the acceleration you feel with your CS prop.
I only started counting one data row before the plane lifted off. I should probably go look at the lat/long and figure out how long the roll was. |
