  • Motor making high pitched whine ??

    Recently my Flightline 1600 Spitfire tipped on its nose at high revs during takeoff.
    When I next powered it up, there was a knocking noise at high revs so I assumed the motor was screwed.
    Ive replaced the motor but it now makes a very high pitched whine when running and it’s very underpowered. So much so that I nearly stalled the aircraft on take off.
    As it’s a new motor, am I correct in now assuming that it must be the ESC ? I’ve bought a programmer but there’s no way to set the ESC to defaults. I’ve messed around with timings but that doesn’t seem to cure it.
    Hope it doesn’t mean a new ESC as well !
