Please see the following link to find out more and patch your radio before it costs you a(nother?) model ... https://plus.google.com/115482461410471042241/posts/LvuET7MeY3R

(The above link references the fix itself, as originally posted by myself at, http://openrcforums.com/forum/viewtopic.php?f=95&t=3594&start=90#p59146)

This dangerous fault exists on all FlySky / Turnigy V2 radios. It affects all boards, including the factory installed one -- but especially boards using anything better/bigger than the original ATmega64A MCU chip -- like the ATmega128 or ATmega256x versions, whether the be upgraded factory boards or complete replacements, such as the v3.2, v4.1 or v4.2 G9X upgrade boards.

Please be aware! The problem does not show up on all '9X radios, all the time. But that doesn't mean it isn't there, waiting to bite you, one hot, fine and dry summer's day. Do not dismiss this post, just because you haven't had any crashes. ALL FlySky and Turnigy V2 radios that I am aware of have this fault!
