7. Q: How to set up the open source flight control to solve the roll axis tilting problem of gimbal when fixed wing turns too fast?

Answer:

Connect the gimbal serial port to a TELEM of a open source flight control (e.g.: Pixhawk) to compensate for horizon drift during high dynamic flight.

FC TELEM port parameter settings: baud rate 115200, MAvlink1.

Set the parameters in ArduPilot:

•SERIALx_BAUD = 115

•SERIALx_PROTOCOL = 1

Where “x” is the port number. The value is 1 (Mavlink).

In addition, set the following message rates for this port:

•SRx_EXTRA1 = 10

•SRx_POSITION = 10

Note: All other SRx_xx parameters should be set to 0 to prevent unnecessary data from overloading the channel.
