is this a good choice

Hi I would like to know if this setup is a good choice. I have the Trex 450 se clone, the Copter x 450, and want to upgrade the motor and ESC. I want to buy the, TP 450-Size 2415-07T Brushless Heli Motor 3850kv and Hobbyking SS Series 40-50A ESC from HobbyKing. Are they any good

40 to 50 Amps is as much as you need regarding ESC. The motor looks OK, but I have no experience of that one.
