Brief:
Bein' new at model rocketry, I didn’t choose a very extravagant style o' rocket, but I tried! :) Usin' My Box O' Parts, me hearties, I found a nose cone and a body tube that fitted together, ya bilge rat, and I be on me way. Arrr! Ahoy! My aim be t' make a simple but pretty design, so i look at what be in me box and ended up with t' design I finally used.

Parts

Bon BonConstruction:

  • 6mm radius tube
  • Ply Wood t' make me fins
  • Nose Cone
  • 22mm Radius Body Tube
  • Engine Block
  • Parachute 10 inch
  • 2 equal length skewers


Ready To LaunchFirstly I designed t' style o' fins I wanted. Aye aye! Aye aye! These can be seen in t' photos, arrr, two fins bein' 1 cm smaller overall than t' other two. Aye aye! I then used me small tubin' t' measure four evenly measured lengths. Aye aye! Begad! I then recorded this length and added 2.5 cm on t' length and measured another 4 small diameter tubes. Aye aye! I then measured another four tubes with an extra 5 cm onto t' original smaller tube’s length. Arrr! I then joined them together by curvin' them around t' body o' t' rocket, smallest t' largest. Ahoy! Two will have t' have t' same orientation, whereas t' other two will have t' be placed around t' rocket differently, arrr, so make sure they will fit when attached. Ya scallywag! Blimey! Do this for t' remainin' three sets o' tubes. Attach t' fins, me hearties, smallest opposite each other and largest opposite each other. Then attach t' sets o' three tubes, ya bilge rat, smallest tube placed against t' largest fin. Avast! Avast, matey, me proud beauty! Repeat this until all sets o' tubes have been fitted and fins are intact. Avast! Avast! Use two equal length skewers and attach t' t' side o' t' body tube in line with t' small fin on both sides. Attach parachute in t' usual manner and paint as required.

Flight:
Three flights had very good launches on a B motor, and one excitin' launch on a C motor. I was really impressed as thar was no damage whatsoever and t' parachute was released just as t' optimum height was reached.

Summary:
Easy and Quick Build, with a very nice flight, ya bilge rat, me bucko, and no considerable drawbacks

Other:
paint some o' t' smaller details like t' skewers before puttin' them onto t' rocket... otherwise it gets very tricky t' get a nice finish... Well, blow me down! Well, me bucko, blow me down! as i learnt!!!
