bad

when I run the motor test it sounds like the motors all sound the same but one or two have a different sound. Anyone else have this experience when testing the motors. I did remove the blades...

First flight before work! Livid!!! Charged up the batteries calibrated everything and was ready to go. Hit the start button. Quiet motors spinning! Angle mode. Step back. Hit up nothing. Ok I wait. Hit the left toggle up nothing!!! Called yuneec. Calibration controller test. Failed J1 J2 only...
