New Design -- Concinnity
Odd-ball design for 18mm engines. The Dv numbers are moderate, but if you reef the shrouds, it should work fine.
Length: 22.50" Diameter: 1.04" (ST-10) Fin Span: 10.75" Weight: 1.26 oz A8-3.......245'......Dv 17 FPS B6-6.......655'......Dv 21 FPS C6-7......1481'......Dv 16 FPS All engines reach safe flight V on a standard 36" x 1/8" rod. The B4-4 is not recommended due to a too-short delay. Enjoy!
