Please help, after a long winter got my Vision 2 out to fly, charged all up.  I calibrate successfully then begin to fly.  At about 10 feet the lights started flashing red and the drone returns home and forces a landing.  What's up?  I updated the firmware, battery is fully charged 4 green bars.  At a loss, want to fly, what's up?

Hello gunzia, your drone might probably activate low battery RTH when the rear LED blinks red. I'd suggest you to discharge the battery thoroughly and then charge it fully to refresh the battery.

Whats the error flashes? If its flashing yellow then it is losing the connection with the either transmitter board or receiver board. It also be a crushed antenna on either transmitter or receiver (on the legs).
Also, check your antenna orientation.

Most likely a battery issue do some more testing and you can isolate the culprit.

Okay completely drained battery then recharged.  Same issue.  All is good taking off, lights are green until around 15 feet then start flashing red and auto land takes place.  Anyone help?

Have you tried a new battery? When this battery is fully charged, is its deviation normal in PT2 software?

Try a different battery..

If you don't have one, try keeping the drone's rotors running while the drone stays on the ground, does the red light still show after, say, five minutes? Also, you can see the battery status in your PT2 software``
