Lab 11 - Motors and Controls

⁠

In Lab 11, we worked on simulating the avionics and control surfaces for the MFE Believer aircraft. We started by calibrating the DATX transmitter so it would communicate properly. After that, we calibrated the sticks and adjusted the home screen. We also opened the LUA script, turned on Multi-Bind, and checked that Channel 1 was set to SBUS on the Tracer Nano RX.

Then we went through all the sensors connected to the cube to make sure everything was working and talking to each other the way it should. After that, we looked at how the DATX inputs lined up with the servo outputs. We matched pitch, roll, yaw, and throttle to the right servo functions, like the flaperons, rudder, V-tail surfaces, and throttle channels. This helped us confirm that the RCMAP_X setup and the SERVO#_FUNCTION settings were correct.

⁠

The last part of the lab focused on the motors and ESC. We connected a servo and an ESC to the right outputs based on our mapping and then checked that the servo moved correctly. After that, we mounted the ESC and motor onto the thrust stand and followed the ESC calibration steps, making sure the aircraft was in Manual Mode and armed in the GCS. Once it was calibrated, we slowly raised the throttle all the way to make sure the motor worked. We noticed there was a dead zone until about four clicks of throttle, and we’ll try to fix that in the next lab.
