If you can, you should go to a club launch and see someone build and fly a reloadable motor. They are not for everyone and Aerotech instructions can be confusing to the uninitiated. I am not try to scare you off; just want you to think about this. And a G76 is a very powerful motor compared to an E. Club launches are great places to learn stuff and to fly. Hopefully, lots of eyes tracking those rockets that go high. You have a much greater chance of recovering your rocket at a club launch than launching by yourself.
