Horrible Lag Time

ArduCopter Copter 4.0

Urgent: S.BUS input on 4.0.1 is stuttering often 100-300ms, up to 500ms Copter 4.0

Hi, After using 4.0.1 for few flights, I observed that it feels like there is lag on RC input. One time I just ARMED the drone and it got the RCIN failsafe and it DISARMED immediately (so there was a >500ms pause on RCIN). After looking on to the log files, the RCIN logging was looking like it is not logging properly. I disregarded that and started to diagnose the problem as hardware problem by replacing RC receiver and simplifying the setup as far as possible, with no help. I also tested it …

Heres an related post. That issue was fixed on 4.0.2 rc1.
