I have recently upgraded from RC7 to RC8. I am having issues with my controls flickering all the time. Played around with the transmitter reliability setting and it seems to make no difference. The screen seems a little more jittery as well. FPS is over 120.
I am using the USB interface cable connected to a spectrum transmitter. I use my sim for practising F3A so I rely on a good rudder feel. RC7 worked well and it felt like my real model. RC8 now feels like I am flying with one of the cheaper products. Hopefully I have a bad setting which will fix my issues otherwise I will continue to use RC7.
