I went from the 120SR to the V911 then to the Blade mSR X.  I really didn't need the V911 because it flies very much like the 120, just much smaller.

I've been flying the mSR X for about 3 months and can now fly without crashing very often.  It's a real handful but I can fly indoors or outdoors as long as wind isn't over 10-15mph, then it gets difficult.
