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!
