T-88 appears to be the structural adhesive of choice but what about lay up
resins. System 3, west, aeropoxy or what? I can use a little help from
experience. Also I asked about Okome plywood usage. No responses.

Why use aluminum or SS when the WAFs are easy to make from the right stuff??
ACS sells the 4130 in the right size so all you have to do is cut to length,
drill some holes and shape.?? I've seen them sell for big $$ and never
understood why except maybe folks want to save a little time.

I am using Inconel fittings. Iconel has the corrosion resistance of stainless
but also has approximately 25% greater strength in yield and ultimate than
4130. Stainless steels are generally not as strong as 4130.
Stainless properties are very different to 4130. It is inferior in pretty much
every way that one might be interested for this application, besides corrosion
resistance. Quite worrying really that people who frankly don't know what
they're talking about do this on critical parts.

I can't remember the last time I saw a set that weren't painted. A magnet would
at least let you know they are steel but not necessarily 4130.

Is stainless stronger than 4130?

The last archive record for Okoume plywood use on the KR was back in 2003.
Anyone have something new to share?

Not to be a doomsayer, but I've seen KR projects that included gear that
weren't worth the gas to drive to the next county to pick them up! I'd say
there's a good chance you'll get lucky though...

While at a fly in over the weekend I was talking to a fellow KR2 owner. Several
years back he had purchased someone else's KR2. He did some work to it, I'm not
sure what all he did. He did get it flying however. He flew it a few times and
then noticed his wing skins were delaminating all over. (

This gentleman has a KR project for sale he inherited from his dad's estate.
Apparently fuselage and tail are complete with landing gear. That's all I know.
He mentioned somewhere in the neighborhood of $400.
