Exclamation New Plan -- Lunar Penetrator

Plan #229...

Combination open-fin and ring-fin design.

One important note: Do not attempt to fly this design on anything less than a "C" motor, as the deployment V will make the model behave just as the name implies. Only with the "C" class or better could I get Dv rates in the safe region. Using "A" and "B" class, this model has Dv rates well over 30 FPS.

Length: 23.3"
Diameter: 0.908" (ST-8)
Fin Span: 3.80"
Ring Diameter: 2.22" (BT-70)
Weight: 1.25 oz

C6-3Q......498'......4 FPS
C6-3.......521'......5 FPS
C4-3.......562'......9 FPS
D10-3......747'.....11 FPS

All motors listed will achieve flight V on a standard rod.
