I could have used the advice when I was covering my fire star. I had somehow managed to put on the silver when I had only heated to 200degres . It was quite a bit looser than the other wing. I called the covering people , they said , go ahead and use a iron and heat to 225 or 250 I did I finally got the fabric tight but what a mess. Lately there has been a lot of sillyness and junk on the list .Thanks again for a post that deals with a sloution to a aircraft problem,and not ,spelling ,gramer,or politics.

Got it up to 1050, I reduced power on final and the motor quit abruptly.I richened the cruise mixture by lowering the clip, all is better.

About 5 miles from the airport I released the control stick and flew hands off back to the airport (rudder only). I flew part of the pattern and did a touch and go after grabbing the control stick on base. Next time I flew a wider pattern using rudder and throttle only, I descended to about 10 feet agl and then had to use the stick as I was crabbed. Found this interesting as I had read quite the contrary about Kolb stability. I enjoy Mythbusters. -------- Dale Whelan 503 powered Firestar II Projection, A simple and interesting Psychological concept Read this topic online here: http://forums.matronics.com/viewtopic.php?p=273300#273300 ________________________________ Message 4 _____________________________________ Time: 09:58:01 AM PST US From: "Jack B. Hart" Subject: Re: Kolb-List: Shrinking Fabric Frank, It reminds me of when I covered the FireFly. Did what I thought was a good job of shrinking the fabric with irons. I had the wings hung up so I could walk around them. I brushed on the sealer, and then followed by spraying aluminum on the upper surfaces and two coats of color with the minimum recommended wait time between coats. It was all done in one afternoon. After cleaning out the spray equipment and changing clothes, I went back down to the shop to take a look. Things did not look good. The fabric was hanging loose and the color was a dull rusty red. Closed the doors and left it. A day later it looked better, and in five days the fabric was tight and the red was bright. That is how long it took the solvent vapors to migrate from the inside of the wing and out of the fabric to the out side. See: http://jackbhart.com/firefly/firefly06.html Jack B.

The FSII that I am currently rebuilding - N582EF - had a bit of dihedral in it & would fly hands off very well, rudder was all you needed to herd it around. I think it is the MKIII that is the contrary varmint, mine certainly won't fly hands off. Don't know about the Firefly or Kolbra.
