Whats the difference between coreless and brushless servos?
 

Hi,

I am buying a new set of Sanwa servos, not sure whether to get the Brushless range (SRG-B*) or the Coreless range (SRG-C*)

Is the difference noticable?? What is the advantage of a brushless servo over a coreless?

Which would suit nitro onroad (8th and 10th) more??

Coreless are about $30US each cheaper. Just trying to work out weather the extra $$ is really worth it for brushless?

Thanks,
