Brief:
Bein' new at model rocketry, I didn’t choose a very extravagant style o' rocket, ya bilge rat, but I tried! :) Usin' My Box O' Parts, I found a nose cone and a body tube that fitted together, ya bilge rat, me hearties, and I was on me way. Well, blow me down! Avast! My aim be t' make a simple but pretty design, arrr, ya bilge rat, so i look at what was 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. Avast, me proud beauty! Blimey! These can be seen in t' photos, two fins bein' 1 cm smaller overall than t' other two. Avast! I then used me small tubin' t' measure four evenly measured lengths. Blimey! Begad! Blimey! I then recorded this length and added 2.5 cm on t' length and measured another 4 small diameter tubes. I then measured another four tubes with an extra 5 cm onto t' original smaller tube’s length. Begad! Blimey! I then joined them together by curvin' them around t' body o' t' rocket, matey, smallest t' largest. Two will have t' have t' same orientation, me hearties, me bucko, matey, whereas t' other two will have t' be placed around t' rocket differently, ya bilge rat, me hearties, so make sure they will fit when attached. Well, blow me down! Ahoy! Blimey! Do this for t' remainin' three sets o' tubes. Ya scallywag! Attach t' fins, 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. Aye aye! Repeat this until all sets o' tubes have been fitted and fins are intact. Use two equal length skewers and attach t' t' side o' t' body tube in line with t' small fin on both sides. Avast! Blimey! 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. Aye aye! I be really impressed as thar was no damage whatsoever and t' parachute be released just as t' optimum height was reached.

Summary:
Easy and Quick Build, with a very nice flight, 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... Ya scallywag! as i learnt!!!
