Lutach,

Mr. Grisa didn't say it was bad to use alot of copper in an ESC. He just said that it made it worse when using higher resistive batteries when running at the voltage limit of the ESC.

During braking with a high quality ESC(low resistant), more current flows back to the battery. But with a high resistant battery and low quality connectors, the back current can't be absorbed well/fast enough. Thus you get a more voltage accross the input of the ESC( taller voltage spike at brakes), than as you would with the use of a higher quality battery pack. With the lower quality batt pack, the ESC will freak out and say "forget this shiat" and let the magic smoke loose.

Dunno if I explained it well enough.
