I didn't set mine (SuperX) to a specific throttle % and it works fine. Now I'm worried...
SleepyC is about as impartial an advocate for anything MR there is, me, not so much. Prior to the NAZA, fly-aways on any other controller was a rare occurrence, now thanks to DJI its part of the MR lexicon. I don't care why DJI's do uncontrolled flight, whether its user or setup errors, or drunk flying there are way too many occurrences.
Now when there's a problem with any controller its almost automatically classified as a fly-away, but I have not had, nor do I know of a single "fly-away" with the SuperX, PARIS MultiWII, OS-CC, HoverflyPro, or even my Gui 330X. To be fair the HoverFlyPro requires a little clarification, the GPS module never really worked so although it never caused me to crash it didn't aways go where I thought it was going so technically that could be considered a "fly-away.'
My point is we can use statistics and blame DJI's problems on everything but DJI and unsuspecting newcomers will continue to purchase DJI controllers and DJI will not be terribly motivated to correct the problems.
