You can use it, but it's way to slow for the tail, it's only .23sec. You really should get the right servo for the 401 gyro (Futaba 9254), the 9254 is .06sec, that's a big difference. You will probably fine the 3004 won't hold the tail very well.

If you do use the 3004 on the tail, make sure your gyro is not in DS mode, DS mode is for digital servos.
