I would like to meet with you, and maybe get a look at one of your airchairs up Sat, 06 Feb 2010 16:39:40 GMT Bret http://groups.yahoo.com/group/Airchairgroup/message/12220 http://groups.yahoo.com/group/Airchairgroup/message/12220 Here's a good resource on wing coverings http://www.auf.asn.au/scratchbuilder/fabrics.html#sailcloth Sat, 06 Feb 2010 15:50:48 GMT Bret http://groups.yahoo.com/group/Airchairgroup/message/12219 http://groups.yahoo.com/group/Airchairgroup/message/12219 Oh, I see you answered my question: Trilam...I'm learning about it online. Thanks.

The sail is sewn with a beading edge which slides in the Sat, 06 Feb 2010 05:13:08 GMT Bret http://groups.yahoo.com/group/Airchairgroup/message/12216 http://groups.yahoo.com/group/Airchairgroup/message/12216 Interesting plane, Alatus. Amazing engineering for allowing breakdown of a real fuselage. What coverings are used on that? Looks like a combination.

So know a little about this. Lots of different materials are used.

What fabric is used on hang gliders, especially rigid wings where the fabric is folded up when you collapse the wing? And what do you use to Thu, 04 Feb 2010 20:08:02 GMT Paul Dewhurst http://groups.yahoo.com/group/Airchairgroup/message/12213 http://groups.yahoo.com/group/Airchairgroup/message/12213 A couple of friends of mine have used it, Terry at http://www.escapadeaircraft.com/ and Paul at http://www.g-tlac.com/aircraft.html and are very happy with Thu, 04 Feb 2010 12:21:25 GMT rexnstudio@... http://groups.yahoo.com/group/Airchairgroup/message/12212 http://groups.yahoo.com/group/Airchairgroup/message/12212 unfortunately, those ailerons are on the glider now... While it would be interesting to know the weight per square foot of finished fabric, there is a minimum Thu, 04 Feb 2010 08:46:23 GMT Bill Jackson http://groups.yahoo.com/group/Airchairgroup/message/12211 http://groups.yahoo.com/group/Airchairgroup/message/12211 One other item with the Oratex would be the lack of fumes. I have covered enough model and full scale planes that I know why they call it "dope".

If you could also give Thu, 04 Feb 2010 06:30:27 GMT Bret http://groups.yahoo.com/group/Airchairgroup/message/12209 http://groups.yahoo.com/group/Airchairgroup/message/12209 Another question.
