Constant beeping from the controller.
Low voltage indication
The right most led on the controller is flashing and the quad refuses to move. In this
situation the lights may flash on the quad for a time and even the start up tones may sound
though it goes no further.
Again a couple of potential issues here. The battery or charger may be damaged and not
charging correctly, though still have enough charge to partly power the quad giving rise to
the above condition. Test the battery and charger as outlined in the above
DOA
section.
Another possibility is a faulty voltage sensor within the quad or even the voltage reading not
being transmitted correctly back to the controller. Unfortunately if it is either of these it is
likely to be a fault in the main board and the only solution I know of is replacing the whole
board.
Though unlikely another possibility is a fault in the controller in it’s communication with the
quad. As a last resort you could attempt to re-bind the quad and controller as outlined
further on.
Gps failure/out of range warning
Also the third light on the controller
is flashing. This indicates the
controller thinks the quad has had
GPS failure (out of range warning),
due to not receiving any GPS data.
Check the quad and make sure there
is a green light on under the GPS
dome of the quad, if not then this is
a known and common fault.
There are a couple of possibilities for
this problem, faulty wiring leading to
the gps unit or a faulty gps unit it’s
self are the most probable causes.
Test all the wiring going to the gps pod for continuity and a good solid solder connection.
Back out with the multimeter, this time set for audible continuity test. If you do not have
this on your meter then set it to resistance. All continuity readings should read as 0 Ohms
resistance. Test from one end of the wire to the other with the GPS unit
disconnected
from
the quad. If the wires and solder joints all check out as ok then the GPS unit will need
replaced as further fault finding on it is near impossible at home.
