    Cesaroni opinions and where to buy

    hi! So I was looking at buying the Cesaroni H225-W rocket motor for my level one certification launch. However, the only reason I am even looking at this one is because the other two motors I was interested in, H110 and H120, are both sold out on most websites I was looking on. i’ve been running...

    Can you build J and higher motors at home without having a Level 1 Certification?

    I just wanted to know if you can build J and higher solid motors at home without Level 1 Certification. Also if there are any federal or state regulations in the California, US that prohibit it.

    Aerotech (Apogee) C6-10 13mm x 83mm Motors

    Aerotech used to make a C6-10 13mm motor, sold through Apogee that was great for competition altitude rockets. I don't believe Aerotech has any plan to bring these back, does anyone still have these laying around or know where it might be possible to buy some?

    Larger 13mm motors?

    I have some Estes A10 engines that I want to fly in a custom rocket to have a high launch in a tiny rocket, so I was wondering if there are larger 13mm motors that can be classified as Bs or Cs, so if you know of any where could I get them or how could I make them with homemade rocket fuel...
