The Insight (squared) is gaining interest in my local area and abroad. Now that I am framing up a third one for someone here in TX, I thought I might share some of the highlights of the build process.

The plane is mainly built using foam cores that are all sheeted with 1/16" contest grade balsa. The only wood frame building is the main fuse box section...kinda like building a Kaos and attaching foam cores to create the top and bttm. shape of the fuse. Of course, the stab, v. fin, and wings are foam cores as well...heck, even the cheeks are sheeted foam. Simple, strong, and light.

I started as usual by cutting out parts for the fuse. The firewall and main formers (to t.e. of wing) are made of 1/8" lite ply. The fuse doublers are made from 1/16" ply and the fuse sides are med. density 1/8" balsa. The formers from the t.e. of the wing back to the tailpost are made from 1/8" balsa. I trued the the 1/8" fuse sides and 1/16" ply fuse doublers. I then used polyurethane glue to attach the fuse doublers to the fuse sides.....so now I have to wait a while for that to dry.......

Here is a pic of the concept, the fuse side plan (top view cut off), the setup prior to gluing the fuse sides, and some of the parts that I was able get cut today.
