The orange and white beaver is anyone else having problems with this airplane killing the new batteries it doesn’t have a low voltage cutoff in the speed control and the transmitter doesn’t warn you and the battery voltage is 2.88 and 2.82 and will not charge now.

A lot of us flew lipos before there were ESCs that would cut power if you ran the battery too low. Not really a problem.
The trick is to fly a first short flight of 3-4 minutes on a model like the little Beaver and then stop the flight and check the voltage after the model has rested for a few minutes.
Full charged voltage is 4.2v per cell. You want to stop flying at 3.8v per cell. If you are at 4.0 per cell after the first flight, your flight, of say 3 minutes, used half the batteries capacity. Ergo, you can fly for around 6 minutes before going below 3.8 per cell.
it is never a good idea to fly to the low voltage cutoff. I always set a timer on the very flight.
