I went that way several years ago. Randy kindly helped me finishing it.
Important notes:
- For first tests limit speed, just in case. I used a low maximum throttle pulse width, slightly over neutral.
- On new versions any channel can be used for mode change, not only 5.
- RTK important for a real circuit. Better “predict” a good day for tests, specially if there is GPS shadowing (on circuit shown the podium caused it to increase, as shown on graphs).
- For arming, disable magnetic interference (single motor). Observe in videos there that car can start and accomplish missions even starting 180º rotated.
See Pixhawk 1 on car shown, which fits on 1/10 car. For newer rovers I used Matek H743 Slim.
Any, but don’t expect real R/C racing car performance. Use a low performance combination.
Any, sticks or wheel, even with two channels (GCS for other than steering/throttle). From the beginning I wanted to use a car radio. A third channel would do mode change (knob in T3VCS shown), and with a four channels radio you could simplify arming/disarming.
Tests pending (perhaps some day…):
- DO_CHANGE_SPEED on straights.
- Object avoidance, or attach a rotating lidar and observe surroundings (yellow radar).
- Simultaneous RTK and live 4G or 5G transmission.
- Trajectories (splines…).
