Exclamation New Image -- Arrowhead

A Schoolyard Sounder.

I wanted something similar to the old Estes Arrow, but not as large and using the 13mm motors. This is a 5FNC model, per James Pierson's comment about the fin count performance, instead of the 6FNC of the original Arrow. As for the name, I know James has a design called Arrow Head; this one is simply a play on the original Estes name.

Length: 13"
Diameter: 1.04" (ST-10)
Fin Span: 2.54"
Weight: 0.6 oz

1/2A3-4T......231'......Dv 22 FPS
A3-4T.........529'......Dv 10 FPS

Both motors reach flight velocity on a standard launch rod.

Enjoy!
