Default New Plan -- Spear Tip II

A 1.4X upscale of the Spear Tip, suggested by Geoffrey Kerbel. This one uses the ST-10180 body tube and the BC-1052 NC.

Simulation shows the performance to match the smaller design, with all three power selections giving deployment Vs of below 10 FPS.

Length: 26.1:
Fin Span: 6.125"
Empty Weight: 1.53 oz

A8-3.....174'.....9 FPS
B4-4.....410'.....3 FPS
C6-5.....875'.....2 FPS
