pixhawk thottle problem

Description-firmware hexa 3.2, Cobra motors & ESCs, all at once sync does well, only stays armed when connected to M/P ( had bad gyro health message a couple of times), I2C has 5vdc not 3.3vdc. All mandatory calibrations are done...no throttle control or motor sync. Everything was bought new...Help
