Just to clarify, it was Spektrum radios that were glitching, presumably getting interference from FlySky radios... easy solution was for drivers with FlySky radios to stand on one side of the stand and Spektrum on the opposite side of the stand. Problem would tend to go away after the radios were more than 4' apart, but if a Fly Sky driver would sway back and forth or move their radio around pointing in different directions during a race, that would cause intermittent glitching on Spektrum systems no matter what the distance was between the radios.

Before FlySky came along, Spektrum was by far the most popular brand at the tracks in my area, soon after FlySky radios showed up, Spektrum has been the least favorite, some tracks have actually banned FlySky radios at one point because they were causing too much interference, ha!
