SITL simulation with real RC input

Hello, I have the RC signal of a real flight experiment and I want to input it into my SITL to perform the same flight and compare the accuracy of the model I developed for my aircraft. I’m using JSBsim with PX4 v1.12.3 on macOS.

I think this can be done by feeding the time history of the RC inputs and switches in the joystick SITL input. @Jaeyoung-Lim do you have any suggestion?

Many thanks,
