The general feeling is that the output from the ESC to the motor is a good source of electrical noise.
If this is so, why don't we put "chokes" on the output wiring to the motor?
The manufacturers do not put any chokes on the output so what do they know different from the "general feeling"?

Good question:
I would expect the noise from a ESC is much like a switching power supply, lots of it but rise times are controlled so the emanated RF noise is in the low frequency range and low in energy.
Gassers have a spark that is high voltage and fast rise time, generating a very narrow impulse that has considerable energy and high frequency components that couple well into other circuits. It is that HV fast rise time that can be the killer for other circuits close by (and every thing is close by on a Heli)

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?
