Sounds like the calibration isn't being done right.
I sometimes have issues when doing the calibration of knowing when each of the 3 axes has finished calibrating - the green light is supposed to go from random green flashing to solid to indicate calibration of that one axis is complete, but sometimes you don't catch it and I think the SuperX moves onto the next axis without you realising it. I've had this lead to a similar condition - yellow light in GPS mode.
The sequence is as stated in the manual,
There is NO compromise! first rotate the vehicle
level and
360 degrees need to do this 2 or 3 times until the
green led pulses slowly, prior to this it flashed fast as you rotated, then move to have the vehicle front point
vertical upwards, and rotate again 360 degrees 2 to 3 times until
LED slow pulses green, then turn vehicle
on it's side and rotate as before until
led turns solid green, if it turns
red you did it wrong, do it again.
Some will find it easier to hold the vehicle and rotate your own body, you might get dizzy but vehicle will be more stable.
