I couldn't resist tackling this one. You need to think bigger than BT-55, if you're going to get the Dv down to below 10 FPS. The one I'm posting here adds Solo's criteria for pre-lasered fins, using the Alpha standard fin shape.

Length: 29.25"
Diameter: 2.04" (ST-20)
Fin Span: 5.04"
Weight: 4.46 oz

Launch Rod: 36" x 1/8"

(3) A10-3T......221'......Dv 2 FPS (or lower)

I didn't think even three A10's would get something this large to move, but RockSim says otherwise. It must be the kick in the pants the A10 has.


And... Don't let this entry stop anyone else from trying! I'm trying to show what is possible, not just the only solution!
