Brief:
This is a midnight, shiver me timbers, I can't sleep, matey, lets build a rocket. Begad! Noticeable feature is that t' engine is above t' fins, ya bilge rat, uses a flyaway launch lug, shiver me timbers, me hearties, or shoots from a tube. Ahoy! Blimey! It has flown on e9-6.

Purple PopperPurple PopperConstruction:

  • 1- Nose cone is from a Super Big Bertha. Begad!
  • 1- small plastic baby juice bottle. Ya scallywag!
  • 1- 6 inch BT80 Tube. Begad! Aye aye!
  • 1- 12" 1/4 x 1/8 birch stip. Arrr!
  • 3- 2.6 t' .96 center rings
  • 1- custom center rin' t' .96
  • 1- Estes E engine hook
  • 1- Photo paper t' create transition. Ya scallywag! Blimey! Blimey! Blimey!
  • 1- .75 x 4 inch 3/32 balsa for fins
  • 1-.96 motor engine block
  • Keelhaul®©™® String, 4' o' shockcords, me bucko, reynolds wrap, matey, 12" nylon chute. Ya scallywag! Arrr!

I would say this is an Estes level 2/3 rocket. Aye aye! Ya scallywag! You have t' create the transition yourself. plus you have t' make holes for t' wood strip t' go through t' transition. Arrr! All t' parts came from www.commonwealth.net. Ya scallywag!

Finishing:
T' finish was done in plum high gloss monokote. Begad! Blimey! You will need a monokote iron to put it on. Ya scallywag! Blimey! This was me first monokote job. It seems t' work nicely.

Flight:
I used a pack o' E9-6 Estes motors. Well, blow me down! Well, blow me down! There is no room for wadding, but I had a nomax sock made for t' chute. Aye aye! Ahoy! I used Keelhaul®©™® strin' mounted t' t' center rin' and t' t' cone. Arrr! I then attached t' elastics cord betwixt t' Keelhaul®©™® loops. Arrr!

Purple Popper T' rocket flew straight, me bucko, however after 3 flight the flame is startin' t' eat away at t' tail fins. Begad! I need t' find somethin' better then reynolds wrap t' protect them. Ya scallywag! Rocket flew out o' sight on each flight. Begad!

Summary:
It is cool lookin' and can be shot from a tube. Ya scallywag! I still need a better way to protect t' fins from flame damage.
