Not able to arm all the motors

Hi all

I am trying arm the UAV/drone using taranis RC. Only 2 motors were working (only two motors were rotating). When i am incresing the throttle , other two motors were start moving(Only when throttle stick is 100%). I am using PixHawk stable version firmware.

You have to calibrate your motors first. It seems to be four motors have calibrated to different values.

Remember to remove the propellers before calibrating
