No, you need 2 seperate ESC's. The Gyro will not control the motor directly, the output of the gyro has to be fed into the ESC to affect the tail speed.
If you were to hook it to the main, it would spin at the same speed, not what you are looking for. And, i'm not sure you can drive 2 motors from 1 BL ESC.

Just a general question... got to thinking... why do I need a different ESC for the tail? Can I not just hook the tail motor to the ESC that is on the main and then the gyro controls how fast or slow right?
