@xfacta and @amilcarlucas I have tried at first to use SBUS because its so much better on the sticks, be to no avail. I don’t remember exactly what didnt work, but I remember I was getting min/max values jitter in the RC tab in mission planner. I could’nt get the sbus output working steadily.
I will try again and link a video to show what I experience.
Amicarlucas, I followed your post (RFDesign TXMOD v2 with Yaapu telemetry script on FrSky Q7) and got the intense jitter after, hence why I chose to use ppm since I could at least fly that way.
Any pointers are welcomed! Thanks for your help.
