Original Design / Scratch Built

I followed the basic instructions from JimZ's site. With the smaller wings, 3" balsa can be used for the wings without having to butt-glue balsa sheets. Several points for construction:
PROs: Only 7 parts. Inexpensive parts. No more butt-gluing!
CONs: Lots of sanding. Parts must fit perfectly. Cut your own balsa.
I would call this a Level 3 kit due to the tricky balsa joints and amount of sanding.
PRO: Easy finishing, just paint the NC red.
CON: Plain looks.
Be careful! The motor must eject out the back to glide. You'll need to add a streamer for it (wrap it around the motor, then insert) to satisfy the RSO and NAR flight rules.
Mine balanced perfectly without any weight. Your results may vary. I estimate a glide ratio of better than 10:1.
The first flight was on an A8-3 in about 3 mph of wind. It launched straight up, did a horizontal figure-8 at about 40ft, then continued vertically to 100 feet of so. The 3-second delay was too long. It ejected at 15ft, glided a few feet, and lawn-darted with no damage. The casing landed 20 feet away.
The second flight was on a B6-4 in the same conditions. It did rather spectacular acrobatics at about 50 feet then again returned to normal flight to about 200 feet. Ejection was again way past at maybe 50 feet. It fell to about 15 feet then settled into a respectable 5-second fast glide. Again, no damage.
CONs: acrobatics may result in DQ'd flight. Needs some altitude to begin glide. Ejects motor casing (intentionally).
The only improvable thing would be a streamer for the motor so it can be used in NAR competition.
PROs: Unique looks. Simple construction. Unusual acrobatics. Great glides
CONs: Motor ejection. Difficult balsa joints.
