Align TRex 450SA

Here is some info on my Align T-Rex 450SA heli. The setup below (for $448.94) has everything but the receiver and battery. (And, of course, you'd need a heli-compatible transmitter.) It's easy to assemble; all you have to do is install the motor, ESC, servos and receiver.  As of March 2008, the 450SA combo can be found for $200.  When I bought it in June 2007 it was $270.

It's possible to get cheaper versions of some of the components, like a cheaper gyro or tail servo (could use S3114 for tail instead of S9650 Digital Servo). But the performance would be degraded a bit (tail would be a bit less "firm" and responsive).

The size of the cutouts for the 3 control servos are the same as a Hitec HS-55 servo (which can also be used, but the S3114 has better numbers). The S3114 servos are slightly short for the cutouts, but they can be made to fit by elongating the mounting holes on one end. Mine are in that way and have never loosened.

See below for some battery options.  I'm a big fan of the FMA Direct Cellpro batteries and chargers.
