When I bought my P3S the latest FWV was 1.06.8 which was showing some issues. I have been running on V. 1.05.7 for some time with no issues. Now I wondering if I might benefit from the latest Ver. Say your piece if you care to, I'd like to hear your opinions.
I´d upgraded to 1.08.10 and after the upgrade had a weak signal issue only one time. It was hovering on place in distance over 100 meters and 5 secs the signal was strong again. From that day the status bar was always solid green. The distance i tried was more than 300 meters and i did not lose the RC signal to the copter. This version might be stable.
The most mobile devices have strong static and dynamic EM fields and can interfere the RC/AC link and let the compass stuck. I separate the AC and RC up to 3-5 meters and the mobile device is nearest 1/2 meter far from the RC.
