Problem
Cause
Solution
Motors may be worn out
Motors will need to be replaced after
extensive use. Worn motors will feel
rough when turned by hand. When
running they will smell like burning
electronics and may make a squeal
ing noise
Rotor blades not mounted
correctly
The rotor blades labeled “A” are for
the front and back while the rotors
labeled “B” are for the right and left.
The rotor should be mounted with
the label facing up so the rotor curves
down
Draganflyer has no/little lift
(continued)
Magnets in motors may have
“dropped” this will reduce the
power output
This is normally caused by a rough
landing or crash. Use flathead screw
driver to push gray magnet up in mo
tor
Low helicopter battery voltage
Fully charge helicopter battery
Draganflyer starts normally but
suddenly stops or disarms
(Red light stays on)
Malfunctioning component on the
circuit board
Contact customer service for repair
information
This is most often due to a broken
part such as the motor mount or
carbon fiber tube
Inspect all motor mounts for cracks
and breaks, you may need to twist
the mount. If the carbon fiber tube is
damaged it is usually a length wise
crack causing it to loose torsion
strength. When twisting the motor
mount a broken carbon fiber tube
will feel “spongy” and elastic. Re
placing these parts requires removing
the motors
Draganflyer shakes violently and
is hard to control
A bent motor shaft will also cause
vibration
Replace the motor
