Exclamation New Design -- Opus Magnum

A BT-55 performance design for 24mm engines. I was trying to keep it with three fins, which looks better, but it took the fourth fin to get the Dv number down below 10 FPS.

Length: 25.35"
Diameter: 1.325" (BT-55)
Fin Span: 8.08"
Weight: 2.01 oz


C11-5.......646'......Dv 3 FPS......30" of guide length
D15-6......1324'......Dv 4 FPS......15" of guide length
E12-6......1742'......Dv 8 FPS......29" of guide length
E9-6.......1783'......Dv 9 FPS......35" of guide length


Share & Enjoy!

All this needs is a decal with Opus doing a Dirty Harry imitation.
