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

Purple PopperPurple PopperConstruction:

  • 1- Nose cone is from a Super Big Bertha. Avast! Begad!
  • 1- small plastic baby juice bottle.
  • 1- 6 inch BT80 Tube. Begad!
  • 1- 12" 1/4 x 1/8 birch stip. Begad!
  • 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, ya bilge rat, 4' o' shockcords, reynolds wrap, 12" nylon chute. Avast! Blimey! Well, shiver me timbers, blow me down! Blimey!

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

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

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

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

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.
