Default Motor beeping

Hi,

I have a brushless outrunner starter motor on my 111cc gas engine
This one !
http://www.bigplanes.nl/contents/en-...o-starter.html

I works well, but when I land and turn off the main switch on my plane, the motor starts beeping. The only way to stop it is to disconnect the LIPO that powered this motor/ESC.
I know it is a warning the the motor has lost signal from the receiver.

I've read on other forums that the beep is being sourced from the ESC and the motor is acting as a speaker? Is this correct?

Can you disable this beeping? The startup ESC beeps are ok and useful but this constant beeping is not...

If you turn off the "main" switch on the plane why isn't that cutting power to this motor/esc? If it doesn't then re-wire so it does. The beeping motor is a warning that the motor/esc is armed at low throttle. That is a function of some esc's and usually can't be disabled without swapping the esc for one without that alarm.

Because the ESC is still getting power from it's own LIPO. The receiver is powered from 2 different LIPOs. So, then the main switch is turned off, the ESC remains powered but the motor is getting power from the LIPO but no input from the receiver...

I think I'l have to go with your suggestion of a different ESC!

Thanks for the input !

Can you add a switch between the ESC and battery?
If you do manage to get an ESC that doesn't beep it's inevitable that you'll forget to disconnect the battery and wind up with a dead battery, since the ESC will always be drawing a little current while connected to the battery.
Neat looking starter setup!

If you don't want to add a third switch (receiver,ignition, starter) then you could get a 60a brushed esc and use that to switch the power from the starter lipo to the starter esc when the receiver switch is turned on/off.
