Intelligent Orientation Control (IOC) Flight
Please configure the IOC function in the NAZA-M assistant software before using.
Definition of Forward Direction: Q
uad -rotor will fly along this direction when you push the elevator stick.
Graphic Description
Nose direction
Forward direction
Before You Start
Usually, the forward direction of a flying aircraft is the same as the nose direction. By using IOC, wherever the
nose points, the forward direction has nothing to do with nose direction:
In course lock flying, the forward direction is the same as a recorded nose direction. See the following
figures (The red and blue arrows on the transmitter is corresponding to pitch and roll operations):
In home lock flying, the forward direction is the same as the direction from home point to aircraft. See the
following figures (The red and blue arrows on the transmitter is corresponding to pitch and roll operations):
Method of Forward Direction & Home Point Recording
If you use the IOC function, please keep the Forward Direction of Course Lock Flying and the home point of
Home Lock Flying in mind at any time. There are two ways to record the forward direction and the home point:
Manually and Automatically. You may choose any one record method.
Course Lock Flight
30 seconds after you power on the
Automatically
quad-rotor.
Switch the S2 between OFF and
CL position quickly 3 to 5 times to
record current nose direction as
Manually
new forward direction after you
power on the quad-rotor for 30s.
(OFF ->CL-> OFF is one time.)

(with GPS & Compass module)
Home point
Over 10m from Home point
Home Lock Flight
Before takeoff, the current position of the
quad-rotor will be saved as home point when you
push the throttle stick for the first time after 6 or
more GPS satellites have been found.
When 6 or more GPS satellites are found, you can
toggle the S2 switch between CL and HL position
quickly 3 to 5 times to record the current position
of the quad-rotor as the new home point. (CL ->
HL -> CL is one time.)

IOC FLYING NOTES! ! !
LED will blink
quickly if recording is successful. LED will blink between
IOC mode only when MC is ready to fly in course lock or home lock modes.
Home lock flying requires that 6 or more GPS satellites are found and the aircraft is further than 10m
away from the home point.
Before you do the home lock flight, you have to fly the aircraft out of the 10m range around home point,
and then flip the switch S2 to HL position to fly in home lock when all the requirements are met. If you
have already toggled the switch S2 to HL position when the aircraft is still in 10m range around home
point, and this is the first time you are going to fly in home lock during the current flight, then if all the
requirements are met, MC will change into home lock automatically when the aircraft flies out of the 10m
range around home point.
When you are flying in home lock mode, if the aircraft is back within the 10m range around home point,
or you switch into ATTI. Mode, or the GPS signal becomes weak, the MC will fly in course lock by the
current forward direction automatically. But this forward direction is NOT the recorded forward direction.
If you switch into course lock now, the MC will fly in course lock using the earlier recorded forward
direction.
When the aircraft is flying in home lock mode far away from you and the home point, please do not
toggle the IOC switch many times quickly so as to avoid the change of home point without you
intentionally knowing.
We suggest that you should know clearly which flight lock method you are going to fly, and you know the
locked forward direction or home point, before you switch on IOC mode during the flight.
Continuously spinning the aircraft in flight will cause a yaw error. In this case, you can stop or slow down
the spinning, so as to have better flight performance.
