Exclamation Revised Plan -- 1987 Estes Catalog Parts Demo

This one took some additional work. The callout for an 18mm motor just would not have worked. This pig needed the power of a D12-5 on a Maxi-Rod to reach a safe flight V.

Looks good visually, but the Dv numbers are high. Reef the parachute.

Length: 25.75"
Diameter: 1.64" (BT-60)
Fin Span: 10.14"
Weight: 3.9 oz

Averaged over 10 runs:

D12-5......614'......Dv 25-27 FPS......48" x 3/16" rod
