I heat formed a piece of fabric to fit inside the rear of the tube, just ahead of the elevator bell crank. then I glued it in place with polly tack. I then cut small slits in it for the elevator and rudder cables. I think if I was doing it again. I would take one inch of the 6 inch tube, split it to fit it inside the main tube. then glue the fabric to the outside of the 1 inch piece , then slid it in the tail boom tube. that way it would have been removable if the need presented itself. that stops the wind movement, I don't know if it would stop critters or not. I suppose you could do it with some screen wire, then cover that with the fabric, the fabric would create an anti chafe buffer to the screen wire and the boom tube, Boyd young mkiii utah ________________________________ Message 6 _____________________________________ Time: 02:17:08 PM PST US From: Thom Riddle Subject: Re: Kolb-List: Breeze up the boom tube Rick, That is an interesting observation. I have never noticed any reverse airflow up my Slingshot's tail but that does not mean it isn't there. IF that phenomenon is not characteristic of the SS but is for most Kolbs I speculate that it might be caused, or at least influenced by the relative positions of the horizontal stabilizer and boom tube. On most Kolbs the leading edge of the HS is well above the centerline of the boom tube, whereas on the SS it is even with (parallel) with the boom tube. There could be other factors too. I am not even sure what would be an easy way to detect/measure this reverse airflow up my SS tail. If it is dramatic as you say on my SS, I would think it would be obvious to me, but it is not at all. How did you determine the speed of roughly half of forward speed? Is it something I could easily replicate on my SS?

The configuration of your cabin has something to do with it. The shuttlecock shape (birdie in polite society) creates all kinds of strange airflows. In my case I was smelling oil sump fumes which I 95% eliminated by routing a vent line to just behind and higher than the prop flange. Those fumes get very well distributed.

When I purchased my FSII it came with two sets of wing struts, one with fairings and one without. The struts with the fairings were off a FS that went into the intra coastal water ways, thus salt water. I was very leery of that so I was not comfortable using them so I have been flying with the non-faired struts. I was however curious as to what impact they would actually have. So I removed the fairings from the struts and installed them on the ones I have been flying with. I just landed after an hour and a half flight with them installed and WOW is all I can say! Very much to my surprise they made an ENORMOUS difference! The airplane was way smoother cruised a good 10 MPH indicated better. The biggest surprise was in glide, best glide, best as I can figure based purely on feel is about 45-48 indicated. The difference was astonishing, at lest to me! In a totally non scientific, seat of the pants, guess, I bet it was 30% farther. Now mind you I am guessing here but to not only see, but feel a difference so significant just amazed me. I'll never fly with out them again! Cruise speed to jumped a good 10MPH at 5500 and the airplane just "Felt" smoother to me. WOW! Any way I just thought I would let every body know what a difference it made on my airplane and highly recommend them to any one not currently using them! Let me know if you guys have seen such a difference and what else you can recommend to further improve my FSII.

Although I've flown a MkIII several times I've never owned one or flown one enough to get to the point that I notice that sort of thing. All my KOLB ownership experience is in Firestars and the Slingshot, both narrow bodied which have not shown the sucking tail syndrome, at least to a degree sufficient to get my attention.

Fly safe and have fun every body! -------- Low and Slow FireStar II Folks: I was also surprised after Brother Jim fabricated me a pair of lift struts from 4130 streamlined tubing. Improvements were amazing. Most notable was elimination of lift strut vibration in flight. This was 1987 and my Firestar which had no brakes. Flying off my 650 foot grass strip, at that time, I had trouble getting the Firestar slowed down before I ran out of airstrip. The improved lift struts necessitated brakes. I had flown the Firestar a couple years without brakes, making flights to Miami, FL, and The Flight Farm near Monterey, NY. The Firestar was much cleaner with improved glide. john h mkIII 7 miles south of Burns Junction, Oregon. ________________________________ Message 14 ____________________________________ Time: 05:32:42 PM PST US Subject: Kolb-List: New Firefly owner looking for Mark III training in PA From: "mburdge39" Hello!

I took it out in my wife's car and stuck it out through the sunroof to calibrate it. Then I positioned it with the probe going back up the boom and went flying. I have lot's of cockpit vents in my Mk III, deliberate and not so and there's no seal at the top of the windscreen. The result is that there's a lot of airflow to create a negative pressure differential in the cabin to suck air in from the boom. That's my theory, anyway.

I cut a round piece of foam with slots for the cables and stuck it in the tube at the front end and it improved things immeasurably.
