I'm glad you got your plane back safely. You did not say what size battery or how old the battery was. Have you cycled your batteries, lately?

To be on the safe side, the next time you go to the field make sure you remove the battery from the charger just before you go. Check the voltage.
check again at the field when you arrive and after each flight. Don't fly with less than 4.6 volts on a 4.8 volt battery.

I had an Alpha Hangar 60 with 4 servos, 4 channels. I was using a 600 mah 4.8 volt Nicad battery. I could get 4 flights. When I got home I would
charge the battery and I usually put in 200 mah. Another words I was averaging 50 mah per flight. Each flight lasted an averay of about 10 minutes.

Batteries do get old and begin to lose their capacity.

It could have been some type of interference, but I lean towards the battery.

Good luck. When you find out for sure, (if you ever do) what the problem was, be sure and post the cause.

Good flying!!!
