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

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

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

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

Purple Popper T' rocket flew straight, 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. Avast, me proud beauty! Arrr! Rocket flew out o' sight on each flight. Well, blow me down! Ahoy!

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