(Scratch) Comanche Chief

Brief:

 

 


T' Comanche-3 CHIEF is a 136% upscale o' t' Estes Comanche-3. Well, blow me down! BT-55 body tube and three 24mm motors. Avast! 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
  • 6 55-50 centerin' rings
  • 3 C55 couplers

Buildin' is pretty straightforward. If you've built t' Comanche-3, arrr, you can upscale it just as easily.

Finishing:
Finish is just simply 3 coats o' sandin' sealer on balsa fins and primer and paint. Begad! Home printed, upscale decals.

Flight:
Motors for t' CHIEF are:

  • Stage 1 - D12-0
  • Stage 2 - E9-0 (An E9-P with t' plug removed)
  • Stage 3 - E9-6

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

Summary:

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