As per last year, I issue a challenge to anyone with a CS prop to do likewise just to compare numbers.
OK, I took the challenge today. Clouds finally cleared enough for me to do a crosswind runway takeoff and straight-ahead climbout to 10,000'. Preferred runway would have put me into the clouds at about 2500'.
I had about 21 gal of fuel on board for a flying weight of about 1,350#.
Home Airport: Arlington KAWO
Airport Altitude: 144'
OAT at 144': 67F
Aircraft: RV-7, CS Hartzell, IO-360 with LSE / Slick ign

Average Climb rate was 1625 fpm from 144' to 10,000'. I lost just a little climb rate from 5000' to 6000' due to inattention to my airspeed. I tried to maintain exactly 100mph for the entire climb, but I let it drift up to 120mph momentarily. I'm sure that I could have been under 6 minutes if I had maintained airspeed.
Maybe I'll figure out how to load my plane up to gross weight (1,800#) and try it again to see what numbers I get.
Man, I love these planes!
