Several people sent me sample graphs to put my numbers into, but Hans van Alphen's was the easiest to use. I got most of my numbers into it, and fudged a couple, but got confused when I got to the moment arm stage, and couldn't get past it. Duncan McBride's explanation finally made the "click" for me, and it all made sense. Now, when I go back to the high desert this weekend, I can do the w&b over again for myself, and know what I'm looking at. Looks like Vamoose is pretty close to "right on the money" just as he sits.

First let me qualify "rough". I don't know how much gas was in your tanks when you weighed it, and I don't have your measurements for wheels and gas tanks. So I used standard numbers as an estimate. Also, I don't know what kind or how many scales you used, or if the scales were tested in any way. As someone else said, you need an accurate scale for the tailwheel, plus with that much weight, 4 (bathroom) scales should be used under the main gear. Is 35% important? Firestars have been allowed to use a 37% limit and I suspect that Mark III's are flying at CG's aft of 35%. But it sure would be nice to know how far aft Mark III's have been tested or flown. You certainly don't need another variable on first flight. Are there any Mark III's flying that have cg's in excess of 35%? Please let us and Larry know.

I have the airspeeds for 4,500 and 5,000 rpm recorded for one-half ball out. But I have not been able to fly due to very high winds. Today was the last chance for this week. Tomorrow I will be going by Wicks and I will pick up some more washers. When I get home next week I will set the engine back where it was at one ball out and run all the tests in one day. It will be interesting to see the effect of number of washers on air speed at the two above rpms. Then when the ball is washered in, I will off set the ball with left rudder pedal pressure and see what air speed comes up. >If I remember correctly, you have increased >incidence of wing and horizontal stabilizer. If >so, we can not compare what is happening to your >Fire Fly with a standard configured one? John, If you look at the incidence angles shown on: http://www.thirdshift.com/jack/firefly/firefly56.html there is a three degree difference in incidence between the wing and the horizontal stabilizer. I have no data to say this is different from the TNK FireFly. If TNK FireFly is well trimmed out in pitch with equal up and down elevator at cruise, I can not see that there will be any difference. Washering the engine front or back will walk both the engine and ball into the correct positions. Jack B.

Each distance from Leading edge of your wing for example. All you have to do then is multiple each weight by its arm. Add the 3 answers and divide by the total weight and this will tell you in inches how far back the CG is from the wing leading edge. It you want a percentage figure take that distance divide by the wings chord (width) time 100 should give the percent.

The reason I say this is my prop turns CCW just like yours. Over the years the paint (which is original 1991/92 paint) on the left side has eroded considerably from exhaust products, oil, dirt, etc. The right side is new looking. I recently removed the fabric from the vertical stabilizer for the first time. It was interesting to find that the lower forward internal brace had blackened the inside of the fabric on the left side. The right side fabric did not show any mark. The lower rear internal brace did not touch the fabric interior left or right. A characteristic of the Kolb aircraft is the prop wash hits the left side of the vertical stabilizer with a CCW prop rotation and just the opposite with a CW rotation. A simple fix, with some experimentation, was the trim tab I now use. Weight of this trim tab and a few rivets is negligible, compared to increased the offset between wing incidence and thrust line. Anyhow, that is the way I do it. :-) john h ________________________________ Message 11 ____________________________________ Time: 03:39:02 PM PST US From: "johnjung@compusenior.com" Subject: Re: Kolb-List: Weight & Balance --> Kolb-List message posted by: "johnjung@compusenior.com" Larry, I noticed that you did list the distance to your front axles, so I corrected my calculations for just that demension and now it shows you close to 35%. Only 21 lbs are needed in the seat next to you. Or some other small change. I also looked over that FAA form that you mentioned and I would trust the results that you got. It must not have been used incorrectly to get anywhere near 29%.

With the keel tube level, you dropped a datum line from the leading edge of the wing down to the keel tube, measured back so far and marked the front limit, then measured back a bit further and marked the rear limit. The you duct taped a short length of 2x4 to the bottom of the keel tube so you wouldn't bend it or cave it in, stuck a length of round tubing at 90 degrees to the tube, climbed up into the seat, had a friend steady the wingtip, and another friend jacked up the airplane with a jack under the round tubing. With full fuel, it shouldn't tip forward with the jack under the front datum, or tip backwards with the jack under the rear datum with zero fuel. The expression on the face of the guy from the Nashville FSDO was wonderful. But he bought it, because that was the only way the factory gave you to calculate it, and it flew just fine.

For just that reason, when I'm talking about a vehicle, or an airplane, I'll always say "driver's side," or "pilot's side," or "passenger's side," etc. When ordering electric motors, I always specify rotation "from the shaft end." Then there's no mix-ups. Lar.
