Happy Thanksgiving to all the Kolbers and Kolbettes on the list, piddled with the FF a bit today and then took it flying for about 15 minutes. Had a good little breeze today, and up to now had only flown it in calm conditions. Flew good, ailerons are heavy as sin, feels way heavier than my MKIII, so the next part of the project will be to change the bellcrank arms for less throw and more leverage. Otherwise it flew fine.
The 277 now vibrates no more than any other 2 stroke above 5,000, and it is slightly worse but still acceptable from 4,500 to 5,000 so will quit worrying about that.
Also, on the other thread; Bill Sullivan asked about the effect of the exhaust pipe heating the wing fabric - now that the outlet is at the front I could hold my hand at the exhaust outlet and was quite surprised that at 6" away there is no heat at all. You have to get to within 2" before it starts to get hot. Wouldn't have guessed that.
It is supposed to get up to 60 tomorrow, so will rejet it a tad richer and try it again. The EGT kept flirting with 1200 today, that is a bit too hot.

Happy Turkey Day you turkeys !  I hope everyone in the Kolb community had a wonderful and meaningful day today. We all have something to be thankful for.
Richard, if it is too chilly there, bring your airplane to Los Angeles to test fly it.... it was only 92 degrees here today!

Got home this afternoon around 4:30, just enough time to swap in the next bigger main jet and go for a short hop before sunset. EGT's are ideal, barely nudges 1150 once in a while, the rest of the time stays around 1050-1100.
Lowered the nose and then BRAKKKKKK! Horrific racket from just above and behind my head, scared the fool out of me! Turned out the gap seal was weakened from where we cut it to fit the new muffler mount, and now whenever you get it over 50, it flutters. LOUDLY!
Anyway, now that the engine is behaving, I can work on a new gap seal.

Before I let go of my Firestar, I made a gap seal out of a wide piece of flashing, reinforced with some hardware store aluminum angle. The front was secured with bolts and nylock nuts through the leading edge tubing extensions. There was a hinged piece that was cut out to go around the engine, and it could be flipped forward for fueling.
I had tried using fabric and velcro, but the glue on the velcro slipped out in the sun.
