I went Raptor 50 for my heli recently. I would not buy another Kyosho. I know the Conecpt 30 is very old, I had that heli 12 years ago. I never got out of hovering it was so unstable, unpredictable and needed constant maintenance. It was a miserable machine. With my Raptor 50, which IMO is very stable, I was doing nose in hover on the first flight, forward flight on flight #2, and WOT forward flight on flight #4 with figure 8's, stall turns and split S's. Yesterday on flight 9 I started loops and rolls. This heli is just plain easy to fly. FWIW, I still wish I could afford an X-Cell machine. I have wanted an X-Cell for about years now, that Fury 3-D sure is enticing. Now my 8+ years of fixed wing experience has helped a bit here, no doubt. Certainly with orientation. For the price I think the Raptor is a good machine. I like the 50 though. I won't have another 30 size machine. There just isn't enough power for my taste.
