Yes I have, both of them in fact.

Others may disagree but I'm not a big fan of the U-Can-Do. Sure it is an OK plane but the big control surfaces really tend to flutter easily even if you are very careful with the throttle. It is also a very fragile plane since it is fairly large but still very light.

The Revolver is another story... this is a beautiful airplane both to look at and fly. Speed? The thing is super slippery in the air and very fast with the right engine. Axial rolls? They are about as close as you can get. Knife edge? It will knife edge as long as you have the nerve to hold it there. There is very little coupling. Inverted flight? Just flip it over and fly upside down all day if you want. You notice a slight difference between inside and outside maneuvers because of the semi-symetrical airfoil but not much. 3D? Not so good. It isn't intended to be a 3D plane. It is a high performance sport plane. Yes it will knife edge, flat spin and just about everything else but no true 3D. It's strength is speed, stability and maneuverability. There is a down side to the plane too: it likes to land hot. It will not slow down as easily as your 4-star or the Somthin Extra. Using the Revolver as a third plane would really depend on the skills of the pilot I think.

You mention wanting a fast plane that is also a good entry level 3d plane. Those things really don't go hand in hand. 3D planes need big control surfaces that don't lend themselves well to going fast. Fast planes are generally very stable which isn't good for 3D. They are two different animals.

I'd go for the SSE. It isn't really a 3D plane but it is a good fun flyer and it can be pretty quick too with a good .46 in the nose. It will also slow down nice and land easily.
