I built this cute rocket glider a while back, and it flew nicely:
I liked it, so I decided to throw common sense to the wind and build a bigger one. See the photos below. 29mm fiberglass motor tube from Mach 1 Rocketry.
Root chord is 10.4", with a 3/8" thick sheet balsa wing for 3.5% airfoil thickness (probably a little on the thin side).
Still yet to arrive is a fiberglass nosecone (can't use plastic as the captive nose mount would cause the nose cone to melt from the ejection charge).
Tailboom will be a 1/4" carbon arrow shaft.
Wing area is about 500 sq in. Oh yeah.
Trying to keep the weight under 16 oz. I'm a little worried about that bit because I'd like to have a 5:1 mean thrust/weight ratio. We shall see...
