What causes motors to lose sync?

On my Y6 with KDE 2814XF-515 motors and HW X-Rotor 40a ESC, Pixhawk, it seems like I have to re-calibrate the ESC's over time. Recently the motors were shaking pretty badly which was obvious when slow motion showed motor #5 definitely spinning odd an

What is INAVerr?

I've asked the question several times in various forums. Nobody has yet answered the question.

The most complete answer was from Randy, but did not define how INAVerr is calculated and why 255 is bad, only that it may be a problem in my logs.

INAVerr- Is it the GPS or FC or neither?

Should I expect a crash at some point?

Nervously I took the Spy 750 Y6 up for the first time in over 3 weeks (had a warm spell of 25F today).

In stab it flies great, then switching to poshold it seemed fine, but did the twitchy thing again for a few se

3DR Power Module

I'm building a Sky Hero Spy 750 using Pixhawk and 3DR GPS/telemetry etc.

Is there an alternative to using the 3DR Power Module to power the Pixhawk? I'm questioning the 14 AGW wires being able to handle the current draw from the motors (KDE 2814XF-515

Pixhawk and gps mounting location

1) Does the Pixhawk need to be at the CG of the copter (a la Naza)?

2) Does the GPS need to located in front of or behind the FC or can it off to the side as long as it is pointing in the same direction?
