where can you purchase the rocket engines?

I can tell you now that this design isn't very stable. The goal with every dumb rocket(no active guidance that is) is to have the center of pressure under the center of gravity. Since rocket engines have a perfectly centered center of pressure on their own and an ulmost perfectly centered cg the cp and cg for this design would be close to right on top of each other, which isn't good enough. With a small engine it might not matter, the engine might not fire long enough with enough force for it to become unstable, but it would be unsafe with anything bigger.

hmmm well my rocket worked with the fuse but maybe you should try the electric ignitor
13 years ago on Introduction
to light the rocket you can use an electric ignitor or just stick a fuse in the small hole at the bottom of the engine. I personally prefer using the fuse because the electric ignitors cost more money and hardly ever work

Your right there are some flaws but this is no super precise rocket, it is just here so that if someone wants to fly a rocket without much expense they can do it in a very simple way.

When submitted for publication, your work should reflect your best effort--your audience wants to see how clever your ideas are and not be distracted by the spelling and punctuation errors.

this is true a) i forgot to talk about safty which IS important and b) iv done this without a lauch lug and it worke fine and stayed in control... but then again i did it at an open field so it wasnt so bad. If you do try this I would most certianly reccomend useing a launch lug with a guiding pole

you need a launch lug a stirrer straw or an eyelet to slide off a rod during launch, guiding the craft upwards, or else it could be dangerous. also be weary of - you can use how ever many fins you want to...

By the way to light it just insert a fuze ate the bottem or use an electric detonator(those never really work for me)
