Is it legal for me to build a large rocket in the U.S.?
<p>So I want to build a rocket from an aluminum pipe, with the inside coated with pyrolitic carbon, and filled APCP finocyl bore and an avionics computer conroling the parachute In the nose cone. I was thinking maybe 40 feet long 2-3 feet around no payload section just a go pro, avionics computer, altimeter, wind speed measure, and parachute/charge in nose. How would I legally do this?</p>

<p>I have spent time researching it. However there is only Information on model rockets as in class 1, 2, and 3. Nothing on actual rockets like CSXT gofast rocket.</p>

<p>First place to start is one of many informational sites Google will show you, i.e. <a href="https://www.nar.org/find-a-local-club/section-guidebook/laws-regulations/" rel="nofollow noreferrer">Laws &amp; Regulations | National Association of Rocketry</a>, to understand the federal and state laws you need to comply with in terms of the size of rocket, the power of the engines, propellant restrictions, launch sites and air space clearances. Obey the law or any number of state and federal agencies will be very unhappy with you.</p>

<p>It's not just that you must follow specific laws, it's more that you have to avoid hitting anything in the sky and store your propellant in a safe place.</p>

<p>The law regarding rockets is listed here :
<a href="https://www.law.cornell.edu/cfr/text/14/101.23" rel="nofollow noreferrer">https://www.law.cornell.edu/cfr/text/14/101.23</a></p>

<p>If your rocket is launched high enough that it could hit a plane, you need to contact the FAA and they will give you a waiver to launch in a certain area during a certain time. </p>

<p>Plenty of model rocket clubs already have waivers during scheduled launches. If you go to their launch, that part is taken care of for you.</p>

<p>I don't know what propellant you intend to use, but you must store it safely according to whatever ATF rules govern the propellant you choose. There is no way to say which rules apply without you telling us what you are using. </p>
