Just read your note on the 11.1V Lipo on the A-10 but am surprised you said it may shorten motor life by a few years.
For me, it shortened motor life to ONEMINUTE!
I bought the A-10 Warthog IIand the stock 650NiMH was anemnic so I bought
the 2200milliamp Lipo & the intelligent charger. The A-10's review did say using the 11.1v 2200ma should be no problem.
And, like you said, the connectors didn't match when I got it ysterday so I had to hack that with some electrical wire (anything thinner burned up!)
but unfortunately/apparently fried the ESC by misconnecting the plus & minus terminals by mistake. So I ghettofied & powered both motors directly from the Lipo by twisting 2 wires to act as a switch. Thus, I left the ailerons, elevators & front wheel servo to be powered by the NiMH.

When we connected both batteries &had the motors blasting away, the motors seemed to have burned-out in ONEMINUTE!
Their speed was very fast to start with and then got slower and slower and slower and then...nothing.
Currently, there's not even a spark when I twist the Lipo's switch (wires) to start the motors any more.
There was also a smell of something burning that my wife & my buddies smelt.
So, finally, I disconnected the Lipo to figure out what was going on.
The wires and motor terminals looked ok. I wonder it the motor coils had burned out.

Do you have any tips on what could've happened?
There is a capacitor across the 2 terminals on each fan motor. Could that have burned out?
Are those motors even capable of handling an 11.1v 2200ma LiPo!?
I'm quite disappointed. The review was misleading.

Please advise if you can.
Thanks,
