Techna , A Sig 4* , CG Tiger or Hanger 9 Pulse would make you a good next plane. And if your looking for something cool , the PTS P51 ARF is a great plane and with the training gear off , it can easily be set up to fly 95 mph plus. But it is not as aerobatic as the other 3 I mentioned .
The 4* would be my first choice , easy to maintain and it is very tuff . It`s just fun to fly . But the others are good planes also.
