8) There has been a lot of talk lately about the Dyna-Wind tubing on forums both here and elsewhere. Here is some facts... I have a 3'X4" tube of DW. It's weight is 25.2 oz. The regular tube weighs 17oz That is a 8.2 oz differance or 2.73 oz per foot. Now a foot of 10.8 oz cloth on a foot of 4" tube is arounds 1.3 oz. if there is no overlap. That is 47.5 % to 52.5 cloth to resin wt. It has been said that a 50-50 is the best possible ratio, and that GLR uses up to 2 X too much epoxy. You do the math. Here is another set of facts, A 4" tube wall is anywhere from .076 to .081 of an inch thick (4 places). The DW is .082 to .087 or about .006 to.007 thick! GLR uses ONLY Areopoxy (PR2032), heat cured as per Areopoxy. All this for $56.95. Regular tubing is $19.15 so for $37.80 more you get a hand layed, beautiful glass tube. Yes, it is not for the most extreme uses, but for 95% of all projects, this is a great product. I will have some at the Meeting next month, you look it over, this stuff is AWSOME. 8)
After its said and done, If you dont lay the glass perfect (kinda like me) I dont think you can beat it. For 37.50 its done. (no mess) 😉

Tim, I think the Dyna-Wind is a wonderful product that may be tougher than most expect. Knowing GLR, I'll bet we could talk Kent into a second layer of glass for those "extreme" blasts, too.
I *might* have a real test for it at MHM 😉
I'll give it a try for sure. I use a 10oz glass aerosleeve sock with West Systems on all my cardboard or phenolic airframes any more just to improve durability. I'm anxious to see these tubes compared to mine. I'll bet at the end of the day the cost is very similar and they would save a ton of time, the problem is, I still like doing the glass myself. I love unwrapping the release film and seeing the shiny smooth hard surface it leaves, but it does take alot of time.
