The last flight was obviously much worse than the other ones in terms of RF link. However I did not notice it during the flight ( no failsafe frames, not red LED blinking, no slow down on the control )

These results are on the lower quality side of the average Weatronic operation. Interesting to show since I flew the phoenix hardcore with this setup and never noticed any control link quality reduction in flight ( 270 mph top speed ).
