How to Troubleshoot Your Drone:
Problem: One of the motors seems to be completely dead or is very hard to spin.
Solutions: Remove the propeller from the problem motor and put it back on, making sure that it is not pressed down too hard. Props which are pushed in too tight can jam the motor
Problem: The quadcopter will not lift off or shoots off to one direction without leaving the ground.
Solution: This typically means that one or more of the props are not installed correctly Please reference your included instructions for proper propeller placement.
Problem: One of the motors seems to stall when tilted slightly.
Solution: This may not mean there is anything wrong with the quadcopter. It has built-in gyroscopes that change power to the motors in order to maintain stability. If this does appear to be a problem, going through the manual recalibration will fix most issues related to this.
Problem: The quadcopter flies off in a certain direction all by itself.
Solutions: (1)This typically means that the quadcopter is not calibrated. Please see the recalibration information above. (2) You may need to use the trim controls to counteract the drift. Please see the section above regarding trim controls.
Problem: The quadcopter will not take off and only skims along the floor.
Solution: This typically means that one or more of the propellers is on incorrectly. Please reference your manual for changing the propellers.
