Model Rockets - No Restrictions
Per NFPA 1122 and FAR 101, model rockets which weigh less than one (1) pound (453 grams) at launch
are not restricted in any way except in areas and situations where they pose a threat to aircraft. However,
these rockets must contain less than 113 grams of total fuel. Some H engines contain less than 113
grams of fuel, however, you need at least a level one high power certification from NAR or TRA to
purchase and use H motors.
In accordance with the safety codes, these rockets must use only pre-manufactured, solid propellant
motors, and do not use metal body tubes, nose cones or fins. Approved materials are paper, wood, and
breakable plastic. Metal is allowed only for minor, non-structural uses (i.e. a motor hook.)
Now that doesn't mean you're not going to get a visit from say the HSA, the FBI,etc etc

Its the last part that can and will send you to jail or get you shut down or arrested for questioning.....that 4 miles better not be right down the landing or takeoff pipeline....
I've attached a .pdf that explains what you need to do for MR/LMR and HPR ...
