Brief:
Being new at model rocketry, I didn’t choose a very extravagant style of rocket, but I tried! :) Using My Box Of Parts, I found a nose cone and a body tube that fitted together, and I was on my way. My aim was to make a simple but pretty design, so i look at what was in my box and ended up with the design I finally used.
Construction:
Firstly I designed the style of fins I wanted. These can be seen in the photos, two fins being 1 cm smaller overall than the other two. I then used my small tubing to measure four evenly measured lengths. I then recorded this length and added 2.5 cm on the length and measured another 4 small diameter tubes. I then measured another four tubes with an extra 5 cm onto the original smaller tube’s length. I then joined them together by curving them around the body of the rocket, smallest to largest. Two will have to have the same orientation, whereas the other two will have to be placed around the rocket differently, so make sure they will fit when attached. Do this for the remaining three sets of tubes. Attach the fins, smallest opposite each other and largest opposite each other. Then attach the sets of three tubes, smallest tube placed against the largest fin. Repeat this until all sets of tubes have been fitted and fins are intact. Use two equal length skewers and attach to the side of the body tube in line with the small fin on both sides. Attach parachute in the usual manner and paint as required.
Flight:
Three flights had very good launches on a B motor, and one exciting launch on a C motor. I was really impressed as there was no damage whatsoever and the parachute was released just as the optimum height was reached.
Summary:
Easy and Quick Build, with a very nice flight, and no considerable drawbacks
Other:
paint some of the smaller details like the skewers before putting them onto the rocket... otherwise it gets very tricky to get a nice finish... as i learnt!!!
