"the only solution I found was to upgrade the firmware as the next release became available. It seemed to clear the issue up. Keep the compass/GPS and flight controller as far as you can from the esc it creates a lot of RF noise."

I've swapped gps/compass module and tried another i2c cable for the compass and same result. 

I originally…"

"Hi Thomas,

I'm having issues with the compass variance error. I've done several live calibrations with tremendous offsets (900 or more) and have tried entering the declination info manually to no avail.

"thanks once again.

Compass variance error seems to be causing auto mode to behave oddly - compass is spinning slowly though I have calibrated several times. I've also tried manual declination setting without luck.
googled it but not certain what is…"

"thanks for that tip Thomas!
I've done a lot of mission planning for air vehicles. Does the rover require a "take off" command in the script or will throttle initiate?

I'm referring to using an aircraft rc controller - in this case a dx6i spektrum with a 6 channel dsmx air receiver for manual control.
The alternative would be a dx4c controller that is used for…"
