Brief:
After a disastrous failure destroyed t' business end o' a 4x18mm rocket, I cut away what survived and tucked it away for future use. I did a build with a Boy Scout troop and ended up with a set o' fins copied from t' Centuri Sky Devil. One thin' led t' another and t' fins were attached t' t' survivin' portion o' t' other rocket.

Construction:
My primary components were:

  • 2” Mailin' tube – 8.25 inches
  • BT-50 – 3” for motor mount
  • Cardstock centerin' rings
  • 4 balsa Centuri Sky Devil fins, drawn and cut by hand. Ya scallywag! Avast! Blimey!
  • Easter egg nose cone
  • Elastic shock cord.
  • Hartle Engineerin' parachute

To be honest I didn’t have much hope for this one as I built it. However, matey, I put t' same care into it as I typically do. I am a huge fan o' t' Elmer’s wood glue and used it throughout.

Finishing:
T' paintin' process wasn’t overly challenging; it just took several steps o' paintin' and masking. Begad! Blimey! All o' the paint be Wal-Mart spray paint.

Flight:
My concerns for this rocket (stability mainly) were absolved on its maiden flight, which was great. Begad! It has flown several times, shiver me timbers, me hearties, each time on a D12. Blimey! Well, me bucko, blow me down! It puts on a good show without goin' overly high. It would probably be very entertainin' on somethin' more potent than black powder.

Summary:
As stated, arrr, me hearties, me hopes were pretty low in t' beginning. Avast! Blimey! I was more or less just throwin' together components. However, this is a fun rocket that flies really well. Arrr! Blimey! And it makes an interestin' companion for me BT-55 upscale o' t' Centuri Sky Devil.
