Hello everyone,
I would like to make my own High Power Rocket but I do not know how to start and how to make the motor.May someone explain that to me , please ?
People are joking with you because your question is akin to: how do I make an automobile and drive it?
If you are interested in rocketry, here is a path for you.
Go to Hobby Lobby, Michael's, Wal-Mart or a local hobby store and buy an Estes Starter Set. Learn to build and launch small rockets on A, B, and C motors. Get good at it.
Go join a club. If you tell us where you are, we will help you find a club close to you. Watch other people fly their high power rockets. Ask them questions.
As someone mentioned, read Modern High Power Rocketry 2 by Canepa, and also read The Handbook of Model Rocketry by G. Harry Stine.
Once you are really good with A, B, and C motors, buy a bigger kit that takes D and E motors.
Next, try your hand at an Estes ProSeries E2X kit and their 29mm E and F motors.
After you get good at that, buy a real mid-power kit (you can find vendor suggestions here) and fly it on G motors.
Finally, once you have mastered this, put a baby H motor in it and get your Level 1 certification. Then you can fly HPR H and I motors at your club.
Do not ever fly HPR rockets without an FAA waiver or you could get arrested. Most clubs have an FAA waiver already, which is why I said to find a club.
Hope this helps.
