Exclamation New Design - Arrow

Sport-payload design for 18mm engines. More ST-11 goodness...

Length: 29.90"
Diameter: 1.17" (ST-11)
Fin Span: 7.92"
Weight: 1.59 oz


A8-3.......170'......Dv 11 FPS
B4-4.......420'......Dv 18 FPS
B6-4.......430'......Dv 20 FPS
C6-5Q......930'......Dv 25 FPS


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

The Estes C6-5 produces Dv numbers about 5-10% higher than the Quest C6-5, with no appreciable altitude improvement.

Three fin sheet patterns included in the ZIP file.

Enjoy!
