Since you can't legally build your own amateur engines, I'm wondering
about the other parts of the bird.  Is it okay to build your own housing
for a engine?  Can you do experiments with manuvering and guidance?

Let's say I build a rocket with an infrared quadrant detector linked
to movable surfaces.  If I use Estes engines and go somewhere legal for
conventional rockets, would I be breaking any laws if I launched a rocket,
and then shot it down with a second rocket (assume no explosive in warhead,
just kinetic energy)?

If I added rockets to a conventional R/C model airplane, for example to
assist takeoff, would that be considered a model rocket or what?
