High powered rockets are in a different class. Lots of rules and regs for larger rocket motors, rockets that weigh more than a certain amount or are capable of reaching higher altitudes. You probably want some kind of ID on there in case you lose track of it and can be returned to you if someone happens to find it.
Decades ago I went to a High Power Rocketry event in the NV desert.
You are correct, very different than the simple kits.
