Some people think Ikon kits are hard to build. I built both the Waco UPF-7 and the Monocoupe D145. They were a lot of work, but I was pleased with the final product.

Now I'm building an ancient Sig Ryan STA. It's from the late '60's or early '70's. This has been a miserable experience. So many design details could have been done better. I'm about to finish it, but am not happy at all. If it flies as bad as someone above mentioned, I'll be very disappointed. I put more work into this kit than I have on any other, including Ikon. And that's including the aftermarket fiberglass parts provided by the seller. If I had to assemble all the stuff provided in the kit, it would never be done.
