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

Purple PopperPurple PopperConstruction:

  • 1- Nose cone is from a Super Big Bertha. Aye aye!
  • 1- small plastic baby juice bottle.
  • 1- 6 inch BT80 Tube. Begad!
  • 1- 12" 1/4 x 1/8 birch stip. Ahoy! Well, blow me down!
  • 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, 4' o' shockcords, reynolds wrap, arrr, 12" nylon chute. Ya scallywag!

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

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

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

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

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