RE: Tower uproar?
The uproar is a great little sport plane, but if you are wanting to try and hover, there is little you can do to make it a good hover machine, without extensive mods, in which case you are better off getting an airplane designed for that purpose.
There are quite a few airplanes out ther for not a whole lot of extra $$$$
If you want a plane that is nimble, easy to build, and good for loops and rolls then that is a god choice.
If you would like a list of what I think to be good 3D and hovering machines let me know and I will give you my opinion.
