Help - I have been using the Phantom Vision 2+ with no issues for the last 3 months.  I did the firmware upgrade this morning to 3.08 and I cant get it to fly.  Everything seems to be fine - motors start - full connectivity - compass calibration etc., but as soon as I try to "take off" it is like the motors arent strong enough to fly.  Left joy stick controls seem to be fine, but right control stick wont elivate the quad copter.  Anyone had this problem?  If not, does anyone know how to revert back to the previous firmware?  Thanks in advance for your help!

Did you recalibrate everything using the Vision Assist App?  You really want to recalibrate after any firmware update or risk having bad things happen.

Have you switched control modes in the assistant ?
Mode 2 is the default with left stick as the throttle.
After any firmware update I always re calibrate the controls in both assistants.

Thanks for the quick responses - NO I didnt do the calibration.  Just did it and short test flight..............all good.  Thanks again and Happy Thanksgiving (assuming you are in the States)

Thanks all for your giving~~ and Happy Thanksgiving~
