Hi guys,
I have an issue with a Naza V2 and would appreciate some help.

When powering up, I'm getting a few green flashes, then red flashes only. I've calibrated the sticks and batteries.

Could anyone provide a next course of action.

Many thanks

rapid red flashing? connect to PC to check the error notice.
if red blinking slowly, check whether your drone is in manual mode

A few green flashes when powering up is normal. Red flashes is beacause the weak GPS signal.
You need to recalibrate the compass.

I am having the same issue. Ive had one successful motor start up after disabling "voltage protection", but other than that the motors will no start spinning even after calibration.
