I fly rocket gliders at my ama field all the time, it depends on the local field conditions and restrictions you may have, we cannot fly turbines at our field for example. There are a lot of dynajet flyers now that hobbyking has imported a relatively inexpensive version, however there is a high fire danger with those if you have any crash as you have gasoline and a hot ignition source, so many are concerned about that. I dont' think ama prevents horizontal rocket flight, air starts are ok as long as they are 100' above the ground in controlled flight I believe, as an example. But AMA does defer to NAR rules for rocket flights, which is why a motor modification is probably a no-no at an ama field, I do those flights on private property.

As for the ME 163 I've done a version and yes on flyng wings it's tough to get the CG far enough back for boost that it isnt' too nose heavy on glide for the elevons, and not too tail heavy so it is very twitchy on boost.
