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
Enjoy!
