Notices:Make sure you have removed all propellers before this step!


STEP1: Receiver Type

Choose the type of your Receiver. If you use S-Bus receiver, please choose S-Bus compatible option: D-Bus. Otherwise choose Tradition.


Please reboot MC and redo the calibration after you change the setup of your transmitter or change your receiver!


If you use S-Bus receiver, the communication of A, E, T, R, U, X1 and X2 channels are all through the D-Bus channel. Right figure shows the connection of default transmitter channels and MC channels in S-Bus receiver (Only first 8 channels of S-Bus receiver are used at the moment).

STEP2: Cut Off Type

Please read the introductions of start and stop motor in this step first, and then choose a cut off type.

1. Start Motor:Pushing throttle stick before takeoff will not start motors. You have to execute any one of following four Combination Stick Commands (CSC)to start motors:

Naza-m-tx cali2.png

2. Stop Motor: We provide two options to stop motors: Immediately, Intelligent.

Immediately Mode

By using this mode, in any control mode, once motors start and throttle stick is over 10%, motors will stop immediately when throttle stick is back under 10% again.In this case, if you push the throttle stick over 10% in 5 seconds after motors stop, motors will re-start, CSC is no need. If you don’t push throttle stick after motors start in three seconds, motors will stop automatically.

Intelligent Mode

By using this mode, different control mode has different way of stopping motors. In Manual Mode, only executing CSCcanstop motors. In Atti Mode orGPS Atti. Mode, any one of following four cases will stop motors:

  • a) You don’t push throttle stick after motors start in three seconds;
  • b) Executing CSC;
  • c) Throttle stick under 10%, and after landing 3 seconds.
  • d) The slope angle of multi-rotor is over 70°, and throttle stick under 10%.

Tips (Intelligent Mode):

You have to execute CSC to start motors. Push throttle stick only will not start motors. In Atti. / GPS Atti. Mode, it has landing judgment, which will stop motors. Start motors in Atti. / GPS Atti. Mode, you have to execute CSC and then push throttle stick over 10% in 3 seconds, otherwise motors will stop after 3 seconds. During normal flight, only pull throttle stick under 10% will not stop motors in any control mode. For safety reason, when the slope angle of multi-rotor is over 70° during the flight in Atti. / GPS Atti. Mode (may be caused by collision, motor and ESC error or propeller broken down), and throttle stick is under 10%, motors will stop automatically. You can stop motors by executing CSCin any control mode.


  • 1. All these two cut off types will work properly only if Tx calibration is correct.
  • 2. When Tx commands are valid under any control modes, motors will start or stop immediately when you execute CSC. It has nothing to do with current throttle stick position. Please DO NOT executes CSCduring flight without any reason.
  • 3. If you choose Immediately mode, you should not pull throttle stick under 10% during flight, because that will stop motors. If you do it accidentally, you should push the throttle stick over 10% in 5 seconds to re-start motors.
  • 4. If you choose Intelligentmode, throttle stick under 10% will trigger landing judgment in any control mode. In this judgment, pitch, roll and yaw controls are denied except throttle, but multi-rotor will still auto level.
  • 5. In any control mode, DO NOT pull throttle stick under 10% during normal flight without any reason.
  • 6. In failed-safe, CSC is denied by MC, motors will hold state.

STEP3: Command Sticks Calibration

Slides Moving Definition:

T:Slide left is craft down, slide right is craft up;

R:Slide left is nose left, slide right is nose right;

E:Slide left is craft back, slide right is craft front;

A:Slide left is craft left, slide right is craft right.

STEP1: Set endpoints of all channels to default values (100%) and set all trims and sub-trims of sticks to 0 on your transmitter first. Keep all curves’ settings as default since the end-point of transmitter sticks will be recorded here.

STEP2: Click START button, and move all of the sticks throughout their complete range several times.

STEP3: After that, click FINISH button when you finished above procedures.

STEP4: If the moving direction of the slide is opposite to the Slides Moving Definition, click the reverse button REV/NORM beside.


1. All slides should become Wkm-rc cali8.png when all the sticks are in the middle positions. If slides cannot go back to center points (become Wkm-rc cali8.png ), just click FINISH, then slides will be at center automatically. If still not, please reboot MC, and do not apply Tx command during the reboot.

2. CSC may not start motors If trims and sub-trims of sticks are not 0!

STEP4: Sticks Monitor

This step is optional. X1 and X2 is for remote gain tuning; X1 is also for gimbal pitch control. Setup the channel on your RC correctly.

STEP5: Control Mode Switch

Whichever 2 or 3 positions switch on your transmitter you have selected to use as control mode switch, wire the right channel of receiver to U port of MC. At each switch position, use end-point fine tuning on your transmitter, move the slider of channel U to GPS(GPS Atti Mode), A (Atti. Mode), M (Manual Mode) to turn the corresponding area blue respectively as showed in the figure.


To move the slider is to adjust channel-selected end-points.

For 2-positions switch, you can assign any two of these three control modes as you like.

If your transmitter supports Fail-Safe, then move the slider to the range which reads Fail-Safe Modetoturn the area blue, set Fail-Safe output of receiver to input port-U.If you switch off your transmitter now, the U channel slide should move to Fail-Safeand turn the corresponding area to blue. Otherwise please reset the fail-safe.MC has built-in auto level Fail-Safe function. That means when the communication between MC and transmitter is disconnected, the outputs of all command sticks from MC will go to center point.If your transmitter has only 4 channels, then MC will work in Atti. Mode by default without Fail-Safefunction.


Please refer to your RC manual for the details of fail-safe setup. With GPS, it is Enhanced Fail-Safe; without GPS, it is Auto Level Fail-Safe, and the aircraft will land.


  • Do NOT set the fail-safe position of throttle under 10% of endpoint.
  • MC would not execute Fail-Safe protection if you don’t set it properly. You can verify the Fail-Safe settings by shutting down your transmitter, and then you can use the following method to check whether MC is already in Fail-Safe mode.
    • Check status bar at the bottom side of the software interface. Control mode will change to Fail-Safe.
    • Check the LED indicator. Read the appendix in this manual for details. LED will give fast yellow blinking if in fail-safe mode.
  • If your transmitter does not support Fail-Safe, the Fail-Safe function will not work when the communication between MC and transmitter is disconnected.
  • Do not use 4-channel Futaba transmitter with S-Bus receiver, otherwise MC will work in Fail-Safe mode.
