Default BL motor sag?
I have a Multiplex 3720/630kv motor that came with my HiTec Weekender. On take off, I was at full throttle and then the motor started sagging. I checked and just before WO throttle the motor sags. I tried with a different esc and same thing. So at this point I am looking at the motor. Any ideas or is this motor now junk?

Thanks

Battery is the cause.

tried 3 different fully charged batteries and it did the same thing with each of them.
