Exclamation New Design - Bee-Thirteen

Another "Schoolyard Sounder". A simple two-stage design for 13mm engines.

Length: 17.50"
Diameter: 0.908" (ST-8)
Fin Span: 3.71"
Weight: 1.30 oz

The only engine combination recommended is the A10-0T to 1/2 A3-4T. Reaches safe flight V on a standard 36" x 1/8" launch rod.

Average altitude is 420'. Average Dv is 17 FPS. Recovery is via 10" parachute (a SEMROC 12" parachute, cut down to 10").
