It is not Beta. I had the upgrade notification pop up on explorer today, but saw nothing when I flew yesterday evening for an hour. I upgraded it and did each of the batteries just to be safe, even though someone stated that this release had no battery updates. Better to take the extra 10 mins and update them anyway IMO. It's raining here, so I won't get to fly until tomorrow to see if I notice anything substantial from the upgrade. Frankly, I have had ZERO issues with this bird, and it lands accurately within inches every single time on RTH.
