I can't say enough good things about my second plane, a Four Star 60. (may she rest in pieces)
With a GMS .76 up front, I could do all the aerobatics I wanted, had almost unlimited vertical, yet could drop the flaperons and fly it around slower (yes, I said slowER) than my trainer. Perhaps that last bit was because I never got quite that good while flying my trainer... I'll have to try it sometime... =]
Seriously though, I was getting discouraged flying my trainer, and thought that I would never learn to do aerobatics. Then I got the 4-star. In a matter of a few flying sessions, I was doing snap rolls, cuban-8's, and inverted passes. The 4-star is the perfect mix of trainer-like forgiveness and smoothness and aerobatic performance capability. And the extra size of the 60-size model helps for visibility and flight stability. And the 60 is now available as either an easy-building kit or in ARF form.
Well, I still haven't said enough, but I've said enough for now.
Wh00ps!
