Flew my Greensleeves electric glider today, with a new battery, new (2.4) receiver. I bought the new LiPo (3 cell) to replace a heavy NiCd/NiMh (7 cell). New battery was charged last month but never flew (weather too bad). So I discharged it a bit. And recharged it fully this morning. Flight was OK but no lift whatsoever so it was pretty much on full power for the whole flight. Suddenly, with no warning, I had no control, no power, no nothing. Felt like someone had unplugged the battery. Normally when the battery gets low the ESC turns off power to the motor but I still get control to the flying surfaces (is this the BEC thing?). But today I had nothing. Luckily the landing was better than I usually manage when I do have power! and there was no damage, except a bent spinner. Now at home I've recharged the battery OK; I now have control but no motor power at all. I did get one little blip, for half a second, but no more. My current theories are
- dodgy connection at the battery, switch or r/x.
- dodgy brand new, expensive receiver.
- I've burned out the motor using 11V instead of 8.4V (but why the total loss of control?)
- none of the above.
Any clues?
