RE: Showtime 50 anyone?
Saito 100 is a bit too much for this plane. (But then again many people think that it is never "too much")
It depends on what do you want. If you have Saito 100 and whant to fly ST50 - go for it.
If you want the best plane for saito 100- Fliton Edge or Extra are going to suit you better - IMHO
