T' Comanche-3 CHIEF is a 136% upscale o' t' Estes Comanche-3. Begad! Avast! BT-55 body tube and three 24mm motors. Blimey! Parachute recovery and an altimeter bay.

Construction:
Parts include:

  • 2 BT-55 Main body tubes
  • 2 BT-55 Booster body tubes
  • 1 ESTES BT-55 nose cone (long)
  • 9 Upscale fins - 1/8 balsa

Buildin' is pretty straightforward. Avast, me proud beauty! If you've built t' Comanche-3, ya bilge rat, shiver me timbers, you can upscale it just as easily.

Flight:
Motors for t' CHIEF are:

  • Stage 1 - D12-0
  • Stage 2 - E9-0 (An E9-P with t' plug removed)

Usual direct stagin' prep. Well, blow me down! Blimey! Add an adapter t' t' D12 t' make t' length right. Ya scallywag! Plus add some BP into t' upper stage nozzles covered with a single layer o' cellophane tape. Avast! This helps with staging.

Summary:

I love this rocket and so does t' club I fly with. Avast! Begad! It's a real crowd pleaser. Well, blow me down! Well, blow me down! T' long burn E9s really do send this bird into t' clouds so t' speak.
