So yes is it required and would I notice a difference for this class of motor?

I'd run it if there is a noticably difference but my MX is the solder post version with the wires already soldered on (the guy at HarrisRc.com did it for me - a real tidy job it is too ) and I'd rather not undo his good work so 'if' I do use it would it be ok to wire it onto the deans plug I'm going to use for the battery (which will most likely be under 3 inches - close to two in length anyway)?

Thanks in advance.

Also, would connecting it to the battery plug (themselves only 2-3 inches from the esc) on a short lead, or direct to the plug, be ok?

As mentioned in my original post I'd rather not touch the tidy soldering job that HarrisRC did for me?
