New Plan -- Argo 18
This is a new plan, but it is also a 15% upscale of the original design I posted here some time back. I have now completed a prototype of that version using 13mm motors, and should be flight-testing it tomorrow (weather permitting, which looks great). This larger version seems better suited for the 18mm motors available, as the Dv numbers are all below 8 FPS.
All motors reach flight velocity on a standard 36" x 1/8" rod.
Length: 19.565"
Diameter: 1.04" (ST-10)
Fin Span: 5.665"
Weight: 1.33 oz
A8-3......200'......Dv 4 FPS
B4-4......460'......Dv 5 FPS
B6-4......470'......Dv 7 FPS
C6-5......965'......Dv 3 FPS
Enjoy!
