Problem
Cause
Solution
Draganflyer has no/little lift
(Continued)
Motors may be worn out
Motors will need to be replaced
usually every 80 full flights, pos-
sibly soon if they are run harder.
Worn motor will feel rough when
turned by hand. When running
they will smell like burning elec-
tronics and may make a squealing
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.
Magnets in motors may have
“dropped” this will reduce the
power output.
This is normally cause by a rough
landing or crash. Use flathead
screwdriver to push gray magnet
up in motor.
Draganflyer starts normally
but suddenly stops or disarms
(Red light stays on)
Low helicopter battery voltage
Fully charge helicopter battery
Malfunctioning component on
the circuit board
Contact customer service for re-
pair information
Draganflyer shakes violently
and hard to control
This is most often due to a bro-
ken 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 damage is usually a
length wise crack causing it to
loose torsion strength. When
twisting the motor mount a bro-
ken carbon fiber tube will feel
“spongy” and elastic. Replacing
these parts requires removing the
motors
A bent motor shaft will also
cause vibration
Replace the motor.
