RC Heli Magazine’s July 2009 issue has one of the first reviews of Align’s new T-Rex 450 Pro helicopter. The 450 Pro is the latest version of Align’s venerable 450 series. It is a significant upgrade from the previous 450 SE v2. The 450 Pro is an all new design. Gone are the dual side frames of earlier kits and the Pro now has a more traditional single piece, carbon fiber side frame. Servo placement has been dramatically altered to improve geometry but makes access to the servos more difficult. Like the v2, the Pro has an all metal head and tail.

Another significant change from the v2 is the inclusion of a Torque Tube for tail drive instead of a belt. We are huge fans of the TT so this a welcome addition. The other big change is the placement of the tail servo. Instead of the typical placement on the tail boom, the 450 Pro places the servo underneath where the tail boom meets the main frame assembly. This helps center of gravity and looks better as well. Lastly, the Pro features new one-piece landing skids.

Like the 500 the 450 Pro includes the newer ‘snub nose’ canopy design. We still prefer the T-Rex 600 design far better but this is a minor point. Also like the 500, the Pro is available in two packages. One has just a motor, esc, and blades and the other also includes servos and a gyro. Of course retailers will certainly offer their own custom packages as well.

RC Heli Mag gave the T-rex 450 Pro high marks all around and said the new heli flies great. If you are looking for a new 450 class heli this is the one to get.

The Heli Tuning site also has a nice 450 Pro review and build article and also build videos.
