Maybe from your source that's true, but from Wicks, they state that both 3/32" stainless and 3/32" galvanized are good for 920 pounds in 7x7 form. In 7x19 form, galvanized is good for 1000 punds, while stainless is good for 920. Hardly what I'd call "far stronger". After all, it's 3/32" cable that's called for in the plans, and as we usually say in KR land, "unless there've been failures, it's not a problem that needs fixing". I'm kind of like Larry on this....I'm not sure what in the world you'd use 1/8" or 3/16" cable for anyway. Just about anything else in the system would break before you could put four thousand pounds on that 1/8" cable. I doubt that my ankles are even rated for 920 pounds...

He said NEVER put Vinyl near Epoxy unless the epoxy is complete dry , as the fumes from the epoxy will not allow the vinyl to dry out. From memory Epoxy will stick vinyl, But Vinyl will not stick fully to epoxy. Epoxy is NOT fuel proof. I have found vinyl easy to use , but a pi\ain to sand.

There are 2 different types of Vinylester resin available. 1. NON Waxed Vinylester dries with a sticky surface and further layers will bond together (with in 3 days). 2. Waxed Vinylester dries with a "dry" surface and requires sanding to enable further layers to bond. I prefer Waxed Vinylester and try to do all glass layers in one lay up. regards Barry Kruyssen Cairns, Australia RAA 19-3873 kr2@BigPond.com http://www.users.bigpond.com/kr2/kr2.htm ----- Original Message ----- From: Glasseyegav To: KR builders and pilots Sent: Wednesday, January 19, 2005 9:52 AM Subject: KR> epoxy tanks with Vinyl top coat I've just finished closing up my left wing tank and glassed the entire bottom of the wing, but that Vinyl ester is a real pain to use !!!!

That is figured with 1" of tire "squash" and zero flex on the gear legs. With the amount that I would expect the gear to flex at gross sitting on the ground I figure I will have at least 9". The next question is was the decision on the prop diameter because that was as big as you could get with your gear and still have adequate ground clearance but a bigger prop would have been better or was it because you decided that 52.5 is what would give you the best performance?

I don't have Grove gear (just standard Diehl taildragger), but my prop is 52.5" in diameter and I have right at 7.75" with properly inflated tires and full fuel tanks, no pilot or passengers, airplane level. I'm not sure there's anybody with Grove gear running a Corvair yet, but somebody's welcome to prove me wrong. Just for reference sake, the lowest part of my stub wing's airfoil is 17" off the floor (17.25" to the lowest part of the main spar). My thrust line is 2.375" below the top of the top longerons. Wheels are Clevelands (not that it matters) with Lamb 11 x 4.00-5 tires. Maybe with a little extrapolation...

My prop is a 52.5" diameter because it's a cut down 54" that I got a deal on from Steve Makish because his Corvair couldn't turn it fast enough. Mine may not either, but I have no doubt I can fly behind it, just not as fast as I want to, maybe. I'd always figured on either a 54" or 52", since I'm going to turn it pretty fast.
