Hi Knight Star,

The only way around the wining of the ESC, audible in the motorwindings, is using an ESC that has a variable frequency range; high in the low rpm's, so the motors run silently and lower in the higher rpm range, in order not to compromise efficiency.

These guys have a few:

You can mail them in English, if you want more information, as the site is only in German.

Regards, Jan.
