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

Purple PopperPurple PopperConstruction:

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

I would say this is an Estes level 2/3 rocket. Begad! Blimey! You have t' create the transition yourself. Avast, me proud beauty! Blimey! plus you have t' make holes for t' wood strip t' go through t' transition. Ahoy! Blimey! Ahoy! Blimey! All t' parts came from www.commonwealth.net. Avast, me proud beauty!

Finishing:
T' finish was done in plum high gloss monokote. Arrr! Blimey! You will need a monokote iron to put it on. Well, blow me down! This be me first monokote job. Avast, me proud beauty! It seems t' work nicely.

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

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

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