TROUBLESHOOTING

POSSIBLE CAUSE

SYMPTOM

POTENTIAL SOLUTION

Dronium III 

AP does not 

respond

1. Communication between 

controller and aircraft was 

not synchronized during 

set up

2. Battery power depleted 

on aircraft, controller or 

both.

1. To synchronize, turn on aircraft 

first, place it on level ground, and 

then turn on controller.

2. Charge aircraft and/or replace 

batteries in controller.

Response to 

control inputs 

intermittent or 

erratic

1. Controller battery power 

nearly depleted.

1. Replace batteries in controller.

Dronium III 

AP will not 

hover or 

strafe  

correctly

1. The aircraft was not  

on level ground during  

synchronization. 

2. Trim settings are incorrect.

1. Re-synchronize aircraft  

and controller.

2. Recalibrate the Altitude Sensor.

3. Reset the trim buttons on 

the controller and re-trim flight 

controls.

*Allow 15 minutes to pass between full flights as this will give the motors a 

chance to cool down.  Failure to do so could wear out and shorten the life  

of the motors.
