    Ok so I'm going to take a crack at this. I just finished up my private cert last June so its all still pretty fresh in my mind. The yellow mark on the airspeed indicator is NOT maneuvering speed it is for fastest cruise and only to be used during calm stable air. Maneuvering speed is NEVER indicated on an ASI because it changes with weight, reason being (going back to the beginning of this post) if you are flying a light aircraft you have to increase AOA a lot before the wing looses lift (critical AOA) and stalls giving you a lot of time to increase stress and load factors that may tear your aircraft apart, If you are flying a heavier aircraft you are already at such a high AOA that it doesn't take much increase in AOA to stall the wing, thus less time to break something. If your wing is stalled it is no longer creating lift thus it doesn't have stress on it and is completely safe as long as you recover from the stall which we should all be able to do with no problems right!!!
    Hope this helps

    What might be the climb rate on that 780lb 912S powered mod 5

    A 780# 912S powered model 5 may out climb a light (<550#) 582 powered early (1-3) model but there is no way in hell it will land shorter or take off shorter.

    We have a Kitfox 5 (same as 7) with a 0-200 based at Richland. It became a 150 the minute the 0-200 cranked over, started and the plane flew. Not trying to be sarcastic, but the combo is heavy and does not perform very well. Does make a great airport to airport cross country cruiser though.

    We also have a KF 5 with 80 hp 912. Now that is one fine plane, although a 912S would be the bees knees!

    Does anyone have the length dimensions for the various Kitfox models? Particulary interested in comparing KF5 and up with earlier ones.

    Model 7 Kitfox
    There is a Model 7 Kitfox advertized on barnstormers that has a modified for more HPower 0-200 Continental.
    It is nicely done and equiped, weighs 850 pounds and they are asking $75,000.
    How well will this Kitfox perform since it basically has the same wing area as my old model I?
    I am sure the stall speed increases with weight.
    A model 5 owner told me his 780 pound Model 5 with a 912S lands shorter than his early 582 powered Kitfox.
    How does a heavier airplane land shorter?
    What speed do the newer Kitfox's powered by the 912S cruise at and at what fuel burn.
    At what point does a heavy Kitfox with a 0-200 become a Cessna 150?
    The owner says his 0-200 equipped model 7 burns 4.5 gallon per hour at 110 mph.
    Thanks Herman 541 404 6464 Oregon

    I dont know about that. I always find something I can take away from a picture, even if it's only a smile. Plane stuff never gets old.

    I wouldn't worry about it. Just slow down for manuvers and turbulance to the lower speed. 85 is nowhere near your stall speed.

    P.S. I don't think any of us will be doing aerobatics in this type of plane anyway. I went up with a WW2 instructor in a T-34 some years ago, and decided quickly that I was not capable of being a fighter pilot. After only about 3 minutes of twists, turns, etc, I asked him to please fly level back to the airport and let me get out and try to walk, or just sit down and watch the world spin by!

    Not too many, and I think most hang out in the Avid Flyer Yahoo Group. I know jeromiemead just put a 912 on his Avid last year, nice guy willing to help, look him up.

    Yes, I agree regarding the Kitfox(s). But I am confused about the seemingly conflicting info in my Aerotrek POH.

    Don't take much to confuse me. I am going with caution, and mark my ASI with the lower numbers for the yellow arc.
    I think I would lean toward Ed Downs' numbers.

    Ed-
    I also have the KF Pilot's Guide rev. 2004-1. My best guess for the disparities is because my KF 4-1200 POH rev. 7/19/94 was published by Skystar Aircraft Corporation while the KF Pilot's Guide is published by Kitfox Aircraft LLC.


    Yes, I believe that is correct Ed.

    Ex., in the 'Required Placards and markings - Airspeed indicator range markings' section of my Aerotrek SLSA POH, it shows the Green Arc 50-109 mph (IAS) and defines it as: "Normal operation range. The lower limit is the maximum-weight zero thrust stall speed with flaps retracted, and the upper limit is maneuvering speed." The Yellow arc 109-143 mph (IAS) and defines it as: "Caution range - operation must be conducted with extreme caution and only in smooth air." The Red line, or VNE for all operation, is 143 mph (IAS).

    However, the POH is confusing (at least to me) about this. In the 'Overview of speed limits' section, it specifically states that "Maneuvering speed (VA)" is 109 mph (IAS), which does coincide with the airspeed indicator markings. Elsewhere, in the 'Operating Limitations' section, it states "Maximum maneuvering speed (VA)" is 85 mph (IAS). Further, in the 'Emergency Procedures - Extreme turbulence encounter' section, it states "When an area of extreme turbulence is encountered, reduce airspeed to approximately 85 mph. Do not reduce the airspeed to lower values to prevent the aircraft from stalling due to turbulence." For reference, stall speeds at M.TO.W. of 1232 lbs. at zero angle of bank is 43 mph (IAS) Flaps down (VSO) and 49 mph (IAS) Flaps up (VS).

    Is this confusing to anyone else or am I missing something?

    Quoting from "KITFOX PILOT'S GUIDE" by Ed Downs, it looks like the "lighter is slower" holds true here.
    Kitfox Lite = 62 mph Manuvering Speed
    Model 1-532 = 75
    Model 2-582 = 76 Model 3-582 = 76 Model XL-503 = 76
    Model 4-1050-582 = 82 Lite Squared-503 =82
    Classic 4-618 = 85 Lite Squared 912 = 85 912S = 85
    Series 5/1400-912 =88
    Series 5/1400-912S = 92 Series 5/6-0-200 = 92 Series 5/6-0-235 = 92 Series 5/6-IO240B =92
    All Series 7 = 92
    Guess you can compare each of these to the Avid / Airdale?
    Don't have a clue why Doug's POH says different. Maybe ask Kitfox?

    I phoned the kitfox factory a number of years back asking a few questions about some of the performance numbers, I was told there were no published figures for maneuvering speed on a model 3. I guess I just assumed this applied to later models… you learn something new every day.
