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

Purple PopperPurple PopperConstruction:

  • 1- Nose cone is from a Super Big Bertha. Arrr!
  • 1- small plastic baby juice bottle. Ya scallywag!
  • 1- 6 inch BT80 Tube. Aye aye! Well, blow me down!
  • 1- 12" 1/4 x 1/8 birch stip.
  • 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!
  • 1- .75 x 4 inch 3/32 balsa for fins
  • 1-.96 motor engine block
  • Keelhaul®©™® String, ya bilge rat, ya bilge rat, 4' o' shockcords, me hearties, reynolds wrap, 12" nylon chute. Avast, me proud beauty! Begad!

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

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

Flight:
I used a pack o' E9-6 Estes motors. There is no room for wadding, shiver me timbers, 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. Ahoy!

Purple Popper T' rocket flew straight, 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. Rocket flew out o' sight on each flight. Begad!

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