They sell it in Big sizesThe extra cost isn't going to be a deal breaker for those of us interested in part 103, but the weight increase could be. An ounce/yd is 15 pounds, just for the fabric on a part 103 120ft^2 wing.
Distressing news for sure!
Does Sig sell their 1.2 oz in bulk? If not where do they source theirs?
in other words the sig is not quite up to new minimum strength, but is over the 35 LB minimum for airworthy......Page 2 your testing data.Lighter weight fabric may be found to have been certified on
gliders or sailplanes and may be used on many uncertificated
aircraft or aircraft in the Light Sport Aircraft (LSA) category.
For aircraft with wing loading less than 8 pounds per square
foot or less, or VNE of 135 mph or less
the fabric is considered
unairworthy when the breaking strength has deteriorated to
below 35 pounds (new minimum strength of 50 pounds).
I know the laser aircraft. Years ago we had one that our local airport that was covered with the clear mylar. it was really interesting watching him land with what appeared to be just a framework. Kind of a Wonder woman type airplane. that mylar or whatever it was always made me nervous because I knew all kind of traffically it could blow out any model airplane. Still the laser is a beautiful ultralight and I would love to have one if I could find a project. I've seen some converted to the single engine which I also thought made better sense. if anybody knows where one is available please contact me here. Thanks for that post and memories. By the way 40 miles an hour? Were you in a dive LOL.?I'll take my "chances" with a mind blowing 40 mph in my Lazair (big wink).
