As you are from Canada, I am asuming that your $900.00 is Canadian dollars and not US$.

In that price range you can get the Century Hawk Pro, OS-37SXH engine, Futaba 6EXH heli radio, Futaba 401 gyro with the 9254 digital servo.

This will get you from hover training and well into 3D aerobatics. If you can spare a bit more money, aother $60.00 will get you the much better 7CH Futaba radio.
