Exclamation New Design -- Wren

In keeping with my desire to come up with designs that are aesthetically pleasing, aerodynamically clean and which give the lowest possible Dv numbers, I present WREN.

Length: 20.20"
Diameter: 1.04" (ST-10)
Fin Span: 5.05"
Weight: 1.18 oz


A8-3......215'......Dv <2 FPS
B4-4......455'......Dv 2-3 FPS
B6-4......457'......Dv 2-3 FPS
C6-5......884'......Dv 13-14 FPS


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

Enjoy!
