Just as a trial fix. Bill Varnes Original Kolb FireStar Audubon NJ Do Not Archive ------------------------------ I was thinking the same thing but I have some aluminum foil tape that would be perfect. It's the same stuff you use on furnace exhaust vents. Just like aluminum foil but with and adhesive backing. I'll give that a try tomorrow when I go to the field. The tape can be removed easily but also will stay in place if it works well. If it does seem to work, are there any drawbacks to using aluminum foil tape compared to a braided sheath in terms of effectiveness? ________________________________ Message 2 _____________________________________ Time: 04:19:18 AM PST US From: "Jack B. Hart" Subject: Re: Kolb-List: New Battery Holder in FireFly > I have a suggestion based on a problem we encountered on our Allegro. We used a couple SS clamps similar to those shown in your photo, to help stabilize the muffler which had a tendency to vibrate a lot and crack. Inadvertently, we had one of the clamps making a relatively sharp bend (like your 90 degree bend at the bottom of your battery) where the screw thread slits were located. With the higher stresses at the corner and the weaker part of the clamp, it broke. When we installed the replacement we positioned it so that the weak part was not at the higher stress area and had no problems since then. > Thom, I purchased some new clamps and repositioned the bends so that no slot was over a corner.

Having said that, the thing scares me too, just so different.

Hart" Subject: Kolb-List: Drooping FireFly Flaperons Kolbers, Yesterday, I flew to Hagerstown to my EAA 373 Chapter meeting. I lifted off into the morning haze and did not climb above 1,000 feet agl to maintain some horizontal visual range. I had a 15 mph head wind so I let the engine run on up to make time. It took me 40 minutes to fly 26 miles or 39 mph ground to ground. On the way home the haze had not improved. I throttled back to 5,000 rpm so I would not get home too soon. One of the fun things about the FireFly is to just be up in the air, to build time and to ride the thermals. It took 28 minutes to get home or 57 mph ground to ground. On the way home, I flew at an 40 mphi. Since the FireFly is trimmed out for the engine running 5,500 rpm, I had to hold considerable back pressure. And then the light bulb went off. I cranked in about one degree of flaperon. The nose came down, the back pressure requirement disappeared, indicated and ground speed picked up little and engine rpm increased enough so that I had to throttle it back a little with no loss of altitude. These continuously adjustable flaperons are just great for trimming to maintain a low drag configuration. Fly Safe. Jack B.

Understand you "cranked in about one degree of flaperon." Does that mean you drooped or reflexed them about one degree? john h mkIII ________________________________ Message 12 ____________________________________ Time: 02:18:16 PM PST US From: Bart Morgan Subject: Re: Kolb-List: Painting Lexan I painted the top part of the canopy on a Dragonfly MK II with the same paint as the plane.

Hart FF004 Hi Jack H: That is what I thought. Drooping flaperons or flaps pushes the nose down, requiring more aft pressure to remain level. Reflexing them will pull the nose up, requiring less aft pressure, or if reflexed enough, you will then have to apply forward pressure on the stick to remain level. This is the opposite effect you got????? Wonder why your aircraft responded in an opposite manner? john h mkIII ________________________________ Message 15 ____________________________________ Time: 07:41:12 PM PST US From: "Denny Rowe" Subject: Re: Kolb-List: Re: Electrical question - shielding Mike, I would try one of Rogers suggestions below if you don't want to disturb the kill switch wiring, just have to tie one end of the shielding to a good ground.

Thanks for all the suggestions. I have good and bad news after working on the airplane. The bad news is that the shielding did nothing. The good news is that the problem has nothing to do with the shielding or interference. My senders are bad. I guess that's more bad news. I started thinking about the problem and realized this was a problem that gradually appeared. It happed slowly over such a long period of time that I just thought it has always been a problem. I'm only 36 and my memory is already starting to go. The senders use to work fine when I initial installed them. The vibration from the airplane is the cause. I found that at 2500 RPM I could get the gauges to work fine. If I tapped on the sender the things went crazy. I guess it's time to contact the company and maybe order new ones. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
