Hello, I'm new to this forum, and also new to starting Mid-High power rocketry. I'm building a large 4.2 ft rocket with a 4'' diameter. It's not done yet but I estimate it'll way about 2-3 pounds. I have no electronic equipment like alterminers inside the rocket, and I'm trying to push the borders of Mid power rocketry to a whole new level. This is a long post, if you could help I would really like it!
First I have a question about choosing the right motor:
I have a 29mm motor mount, so I can only accept a large high power G motor, (has to have a impulse of over 100 n/s) and I don't want a online HazMat fee, (I'm trying to stay in the 100-dollar range) also, I want a single shot, not a re-loadable or kit motor, since I'm kinda a newbie to rocketry, I don't have a L1 certificate. Buying it in person at a store would be the best option, since I don't want to pay a HazMat fee and I don't want to email my I.D. and everything.
Second I have a question about bulkheads:
I ran into this whole thing about having a bulkhead to protect your payload from burning and stuff, and I don't know what to do, my shock cord is running from the top motor mount ring to the nosecone, so I don't think it's necessary.
Third I have a question about ejection charges:
Do I need a ejection charge to pop the top off my nosecone? I can't legally buy black powder in my area, and I don't think it's needed. Is it only needed when your working with really big rockets? I have a 18 inch nosecone btw, it weighs 10.52oz
Fourth, I have a question about my materials.
In all, these are the things I have:
A motor mount with two rings
A body tube
A nosecone
A shock cord
That little ring thing to attach the shock cord to the nosecone (On the top of the higher centering ring on the motor mount)
That cooling recovery paper wadding stuff
A 48'' nylon parachute
And I'm building my fins
Is there anything I'm missing?
I know this is a really long thread but I'm new to this higher power kind of stuff, and if someone experienced could help me I'd REALLY appreciate it. Sorry about all the questions!
Happy Launching!
