Yes. The switch that comes with an ESC turns off the BEC power to the
RX, so it'll turn off the motor in most cases. It also doesn't switch
much current, so it can be a small switch.
Mostly it's just a `safety' thing -- turn it off when your plane lands
so the motor doesn't roar to life due to a glitch. But your battery
is still being drained slightly by the ESC, so you don't use it to
turn off your model for storage or the trip home.
| I believe Red has the right idea about switching off the battery lead.
I'm not sure I agree (with putting a switch there.) Sure, it would be
convenient, but it also introduces resistance where there was none
before, reducing the performance of your plane. And even if you can
put a smaller switch than you would normally expect to handle that
much current, it's still extra weight.
I think I'll just stick with pulling the battery connector, though
that can lead to the connector wearing out, and you could accidently
pull some wires loose.
Of course, I do prefer to put a fuse in there, either between the
motor and ESC for a brushed motor, or battery and ESC/BEC for a
brushless plane. I realize that if the fuse blows in the latter case
I lose all control, but if the fuse wasn't there, the ESC would
probably burn up and then I'd lose all control anyways. The fuse adds
some resistance and weight, but I think it's worth it. But a big
switch? I'm not so sure.
