RE: Upgrade CP or get a T-Rex?
I would say definately get a T-rex and if you do you should buy the 450SE It will be about $1000 dollars to start of but youll learn to fly a lot faster than on those Blade CP's or Axe CP's I have one with 3 HS-065 servos and an Airtronics 94761z servo on the tail with a Futaba 401 gyro its a great helicopter.
