Cannot perform a motor test?

Quad, x-8, Copter 3.5.5, Pixhawk 2.1, T-Motor U5’s, T-motor Air 40A ESC. Mission Planner 3.5
I can get the motors to arm and spin but I cannot perform the motor test. I individually calibrated the ESC’s and also did a full calibration. ESC settings is at Normal. When I get the Green flashing light on the Here, and press the button, I get no corresponding beep. When I try to select a motor to test, I receive a noise and the Here flashes red and blue and goes back to green. Like I said I can then arm all motors and they will all spin. One flight but reluctant to do so again.

Thoughts?

Thanks

Bump up the throttle percentage and run time. I have to use at least 10% throttle.

Be advised that the Motor Test Sequence, A,B,C,D… DOES NOT FOLLOW MOTOR ORDER 1,2,3,4…

Son-of-a-gun, that worked. Thanks very much for the insight.

No problem… Just one of the many ‘gotchas’ that gives Arducopter its unique character.
