PROBLEM
Possible Causes
Solutions
Motors Don’t Spin
Power Supply is
not connected
Power supply
polarity is inverted
POWER value set
to 0
Check all connections
Double check POWER
settings
Camera trys to
stabilize but falls to
side
Camera not
balanced
There is a broken
motor winding or
one phase of
motor has failed
POWER not set
high enough
Balance the Camera
Check Motor windings
o
Roll/Pitch ABC phase
resistance = 14.5-16
ohms
o
Pan ABC phase
resistance = 11.5-12.5
ohms
Increase Power Value
During fast YAW
rotations, camera
horizon deflects on
Roll and slowly comes
back level
Bad Accelerometer
Calibration
Sensor is mounted
crooked / not parallel
to motor axis
Perform 6 Point IMU calibration
Align Sensor Square with Axis
During Fast motion
with acceleration,
camera deflects and
then slowly comes
back level
This is normal affects of
acceleration
Try to increase Gyro Trust value in
Advance tab (default Silk values
should not cause this)
Camera slowly drifts
by any or all axes just
after power on
This is from BAD gyro
calibration.
Recalibrate Gyro (5 second press of
menu button or through GUI)
High Frequency
Oscillations
Sensor Feedback as
result of too high D
parameter
Check the Realtime Data graphs to
determine which axis is problem
and lower D value
Low Frequency
Oscillations
Sensor feedback as result
of too high D or P
parameter
Lower P Value, Increase D value
GUI cannot connect
to board
Wrong COM port
selected. GUI and
firmware version
mistmatch
Try different COM port – check
driver installation. Check Firmware
and GUI version
