I am unable to fly my custom frame with the A3 flight controller.  I am running a these escswith T-motor MT4004 (300kv).  My frame is about 24" diagonally from M1 to M4 and I am using 15" props that I know are balanced.  The A3 parameters on this flight were Pitch: 140, Roll: 140, Yaw: 130, Throttle: 100, Yaw Endpoint: 60, Brake: 80, Attitude: 20, Attitude Gain: 90.
I am barely able to get off the ground before the quadcopter goes unstable.  I have tried a range of different A3 parameters and get this same behavior.  What is my issue here?

       Analyze the condition of the battery. If the battery voltage varies within the acceptable, then you most likely a problem with the gyro unit.
Try replacing the unit IMU.   I wish you as soon as possible to solve this problem!
