This is a bummer. I hear about these problems caused by the new firmware, but the new takeoff and the much more stable flight is so nice, I'm stuck between downgrading or keeping it here. Hopefully they just release a 3.1.1 or something to fix these glitches.
Zeke, if it is working for you, keep flying it. Some are having issues based on their Tx and if they are in Intelligent Mode. I would go to Immediate Mode for the time being. Make sure you review what happens in this mode before you fly.
