It can't be that simple. Don't radio controlled aircraft fly through
the air (out of ground effect)?
Just wondering,

At best they would be "air vehicles" under FAR 103 since they carry
less than 5 gals of gas and weighs less than 254 lbs. Basically this
means you can't fly them over congested areas.

Homemade rockets ARE regulated. Its been a while since I've launched
rockets but I believe anything with an "H" engine or larger requires
certification. There are examiners around that do the certifications.
