Ok so went for a quick flight this evening and ran into some trouble. Hadn't flown my phantom for about a month or so. My battery was reading about 50% but my remote controller was low about 17%. This wasn't an issue i felt as was only planning a short distance 5 minute flight or so at low altitude. When i was up about 30 secs i got the warning message 'propulsion limited to protect battery' then a few seconds later the drone went into an automatic landing maneuover. I still had control and i was able to try fly back to my take off point at the back of my house, however i had to battle against the auto hard descent to keep enough altitude to get back. I did get back... however on landing i was unable to stop the motors via pulling diagonal on control sticks and then my drone fell over on one side throwing the back right prop into the grass (soft ground) It then began to emit a very loud squealing sound and the motor began to smell as if it was burning. The other props had stopped at this stage but the only way i could get the burning motor to stop was to pull the batter from the bird. The silver metal casing on the motor was red hot and again a smell of burning. I allowed the motor to cool somewhat and then put a new battery in and all seems fine. All motors starting etc but im still worried that some damage has been done and i would be fear full of a long distance flight etc. Any ideas on how to check the health of my bird?
