I finally finished setting up my new workshop last night and immediately dug into my SE kit. I built the control surfaces and tail first since I was looking for some instant gratification. Next, I started on the right wing.
My overall impressions of the kit are quite good. It's the third Sig kit I've built and is a marked improvement from the Kadet Mk II and Komander I built 15 years ago. The parts fit was about 99% compared to about 50% on the other two kits. Some of the parts in the tail in control surfaces could have fit better since there were a couple of parts where the half moon alignment dot was larger than the adjoining dimple. And, as it seems everyone else has mentioned, the holes in the plywood ribs for the wing tube socket were just a tad on the tight side

But, the slots in the ribs for the spars and leading edge were perfect. If there's one thing I complain about, it's ribs that don't fit the spars but this kit didn't disappoint me. But, if there's one gripe I have, it's that the shear webs were not precut and the rib spacings are not consistent. With all of the work Sig put into this kit, they could have at least equally spaced the ribs and precut the shear webs.
More fun with the CA bottle tonight!
