Here's another "fun-fly" design with soft recovery on all of the primary engines. Be sure to reinforce the T-Tail fins along the rear edge with something more substantial than balsa - perhaps some 3/32" x 1/8" basswood strips - to take the landing loads.

Length: 18.25"
Diameter: 1.04" (ST-10)
Fin Span: 9.04"
Weight: 1.19 oz


A8-3......221'......Dv < 1 FPS
B4-4......482'......Dv 5 FPS
B6-4......487'......Dv 9 FPS
C6-5......973'......Dv 3 FPS


All engines reach safe flight V on a 36" x 1/8" standard rod.

Enjoy!
