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

Purple PopperPurple PopperConstruction:

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

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

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

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

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

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