Bob ________________________________ Message 2 _____________________________________ Time: 11:00:33 AM PST US Subject: Kolb-List: Non certified fabric at ACS From: Richard Girard Does anyone on the forum have experience with the non certified 2.7 oz. dacron Spruce is offering (part no. 09-00300). Better yet, anyone compared it with the 2.7 oz. Polyfiber fabric? The cracks in the Aerothane are starting to turn to peeled areas and at less than half the cost it makes doing a re-cover on Zulu Delta possible sooner than I had hoped. Rick Girard ________________________________ Message 3 _____________________________________ Time: 11:17:11 AM PST US From: "John Hauck" Subject: Re: Kolb-List: Non certified fabric at ACS This is by no means a scientific response, but has been my understanding for many years. Manufacture and sales of virgin (unshrunk) polyester-dacron aircraft fabric is limited to one or a couple mills. A certain amount of lubricant is necessary during weaving to prevent burning the threads. The lighter and tighter the fabric, the more lube necessary. Thus HS90X was a very difficult to seal and fill all the damn pin holes. Biggest expense with polyfiber is its certification, just like other aircraft parts. That polyfiber stamp costs as much as the fabric. I have used generic virgin polyester-dacron with success. Would use it again if necessary. john h mkIII Does anyone on the forum have experience with the non certified 2.7 oz. dacron Spruce is offering (part no. 09-00300).

I did several touch an goes, and buzzed a local corn field, and I also got to see what aileron flutter is like also, didn't care for that much. My landings were pretty good, the transition wasn't too bad and it was really incredible, I loved it and am now looking forward to getting back out again soon. I remember all the advice you guys give me and I remember what Mike Fisher told me about aileron flutter and it was like you were all in the plane with me. Thanks and happy flying.

Bill, the Flyer was the predecessor to the UltraStar. Twin Solo engines, though I believe earlier versions had some different smaller engines. It didn't fold like the US, had a two spar / two strut wing design unlike the single large spar and single strut of the US. I've seen a few but never flown one. I'm told it couldn't quite maintain level flight on one engine, but could cover a lot of ground in the shallow descent. -Dana -- Never write device drivers on acid. ________________________________ Message 7 _____________________________________ Time: 04:21:15 PM PST US From: Herb Subject: Re: Kolb-List: Non certified fabric at ACS Rick I always use uncertified...works just fine..

I may have enough to cover the wings left over from vacuum bagging projects. Herb, did you use the lighter weight for ailerons and flaps?

Rick Girard =================================================== Realize you asked Herb. Flaps are vulnerable to FOD and prop drumming, plus scrw drivers and other tools and stuff. I use heavy fabric on flaps and ailerons. I have 18 year old/3,000+ dacron on my flaps that are still serviceable. john h mkIII ________________________________ Message 10 ____________________________________ Time: 06:20:53 PM PST US From: Herb Subject: Re: Kolb-List: Non certified fabric at ACS Rick I used the 2.7 for all surfaces when I rebuilt my Kolb MkIII back in the mid 90's.

Plan B, use tubing instead of steel rod and pack one end with lead. I understand the flaps and ailerons on the B-36 were framed with magnesium. I suppose that's a little extreme, though. :-} Rick On Mon, Jun 21, 2010 at 8:07 PM, John Hauck wrote: > > > Herb, did you use the lighter weight for ailerons and flaps? > > > Rick Girard > =================================================== > > > Realize you asked Herb. > > Flaps are vulnerable to FOD and prop drumming, plus scrw drivers and other > tools and stuff. > > I use heavy fabric on flaps and ailerons. > > I have 18 year old/3,000+ dacron on my flaps that are still serviceable. > > john h > mkIII > > ------------------------------------------------------------------------------------- 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.
