    I'm not sure that I've ever seen it quite that low. 500 fpm is probably the lowest I've seen it at gross on a hot day. Keep in mind though that there are not a lot of mountains in southeast Wisconsin where I fly.

    On a cold day when I'm by myself, I've seen well over 1600 fpm.

    Alex (@alexM) and I flew a 912iS powered Kitfox recently in the western Rockies of Colorado. I don't recall exact numbers, but performance was perfectly acceptable climbing out of Montrose with OAT in the mid-40s. We got the plane up to 12,300' MSL before it ran out of steam. This was with two grown men, nearly full fuel and ~30lbs of baggage. The plane has a 3-blade fixed prop; not sure of brand.

    Thanks Eric! I was just a bit concerned as I'm about ready to pull the trigger on the motor for my kf7 and I saw a video from 7Kilofox on youtube where he mentions his STI not being a very good climber when at gross (he mentions something like 300FPM...) He's at sea level but I can see the humidity and temps in Florida where he's at be an issue.
    My Model 7 has the standard wing but similar bushgear landing gear setup as his.

    The airplane we were flying has Shock Monster gear, 29" tires and no wing strut fairings, so pretty much as draggy as a Kitfox gets.

    Keep in mind that 7kilofox also flies a Cessna 210, so his standards for airplane performance may be somewhat skewed.

    Excellent! I'm also on shock monsters and 29's with no fairings yet. This makes me feel much better and confident about the 912iS

    Did the lift strut fairings, covered the gear legs with leading and trailing edges, fairings on the shockmonster shocks.
    Went from 90 to 105 cruise, less map and 7 gallons per hour to 6
