Just got it running and HOLY F*CK...this is the best flying machine I have ever flown in this size range. Im in love!!! Would recommend it to anyone and everyone. Even if pattern is more your style, you set it up right and it will track like on rails. This thing will do anything I want. Love it with the SFG's and without. The Saito .91S is the perfect motor if you want the 4 stroke. If 2 stroke is your pref. then I would recommend a 60 size engine. If going electric I would go with the 80 size range. The X50 and the Showtime both have the same engine recommendation but the Showtime's weight is more so thats why I got the Saito 91. Small lightweight (for a 91) and plenty of power!!! But not way too much power. Still able to control the throttle perfect. If you are looking for a new 3d plane in a 50 size...this should be the one. It built fast and easy. Pretty good quality too. Next I think I will try the Showtime 4D after a while unless they come out with something new.
