Brief:
This is a midnight, matey, I can't sleep, lets build a rocket. Blimey! Noticeable feature is that t' engine is above t' fins, uses a flyaway launch lug, shiver me timbers, or shoots from a tube. Begad! Avast, me proud beauty! 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. Well, blow me down! Blimey! Well, shiver me timbers, blow me down! Blimey!
  • 1- 6 inch BT80 Tube. Blimey! Avast, ya bilge rat, me proud beauty! Blimey!
  • 1- 12" 1/4 x 1/8 birch stip. Begad! Blimey!
  • 3- 2.6 t' .96 center rings
  • 1- custom center rin' t' .96
  • 1- Estes E engine hook
  • 1- Photo paper t' create transition. Well, blow me down!
  • 1- .75 x 4 inch 3/32 balsa for fins
  • 1-.96 motor engine block
  • Keelhaul®©™® String, 4' o' shockcords, arrr, reynolds wrap, 12" nylon chute. Begad! Aye aye!

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

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

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

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

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