when i reached to motor calibration and connect all electronics and power up the system the motor start peep and did not stop it seams did not recognized be cc3d .
while the servos working fine
please help me with this issue

[Mateusz]

Normall way to calibrate ESC is

• Battery not connected
• Max out servo slider
• Battery connected
• Wait for beeps
• Down servo sliders to minimum
• Wait for final beeps
• Disconnect battery

This is exactly what ESC calibration wizard asks user to do. Check if you followed these steps. If you did that and it still does not work, provide some more information about firmware flight controller version, esc protocol used, esc type/brand and what firmware is running on ESC.

When i connect esc to reciver directly its working fine its calibeated .
But when i connect it to no 4 on cc3d output the motor continue beeping its not recognize by cc3d board .

...provide some more information about firmware flight controller version, esc protocol used, esc type/brand and what firmware is running on ESC.

Especially ESC protocol you picked. It might be you picked wrong protocol that is not supported by your ESC. Also check wiring and if signal and gnd are connected to correct pads.

I have try with 2 different esc
One of them turnigy .
But the probleme still .

If Esc do continuous Beeps when you apply the power this means the minimal value needed for Esc initialization is not reached and for safety reasons the Esc do not initialize.

In Output tab, the bank used for Output4 (look color scheme) need to the set as PWM-50Hz

Two options:
- Calibrate using the Output tab https://librepilot.atlassian.net/wiki/display/LPDOC/ESC+Calibration
- Set the min/max value for the Output4 the same as your min/max from your receiver, used/calibrated in Input tab.

i try every think but motor still did not response
i think ch. no 4 output damaged because when i try with multi rotor the ch no 4 did not response as well.

could you tell me if there is a way to use another output channel instead of ch no 4 for motor in fix wing?

[f5soh]

yes, you can change the output for the motor.

Go to the Vehicle tab and choose the output for motor.
Reboot the board and go back to the output tab for calibration / test

Thats great
But i how to control motor speed by throatel chanal of the radio
How to setup the input and output

[f5soh]

?

You can setup the input using the radio wizard.

Simply assign the motor to another spare channel output using the vehicle tab.

[aymanromi]

I use ch no 5
But when i move the throtal stick
The motor did not respons.

[f5soh]

Did you arm the board ?

[aymanromi]

Could you please tell me how to arm the board

[f5soh]

You need to choose the arming settings into the Input > Arming Settings tab.

Better use a switch (configured accessory) for a fixed wing.

[aymanromi]

i did not understand
could you explain to me
