I'm going to start collecting Problems and possible solutions Posted on the Main Xtreme thread.
It's hard to locate important information like this when looking for it.

- a lose wire connection to one of the motors
- too much moisture or moist dust/dirt layer on the flight controller (in most cases)
The EOX performs a system and motor driver check at start-up. In case that the PCBA is too moist or has a layer of moist dust, the motor driver check may fail since it detects a potential over current. This is a "false" alarm due to the additional current leaking due to the moist conditions. The test is only performed while arming the motors before each flight. The test is not performed during flights.
We will have a new firmware out and in production by June to address this issue which is more or less a "cosmetic" improvement. If you let your unit rest and sit for a while in an dry environment you will be able to fly again unless a wire connection is broken.
The new firmware will address 3 issues. We are are currently evaluating to provide firmware upgrade service within the USA for customers who wish to perform such upgrade. Please do not ask us now since we are still looking into a proper procedure. The issues are not failure or bug related but pure improvements. The new version includes:
a) Improvement: Motor driver check at start-up improved to address one side not arming issue (randomly)
b) New: Orientation LEDs will now also be used to indicate low battery status
c) Improvement: Gyro reset is only possible while motors are not armed (currently they can be armed while motors are at idle RPM -> throttle at zero while motors are armed)
V31 Firmware FC has been released with the above mentioned improvements.
