hpi cup racer...novak brushless
i am about to install the HAVOC 3S/BALLISTIC SPEC BRUSHLESS SYSTEM(13.5)
into my hpi cup racer....my question is should i change the plastic diff cups...or will they hold up with the brushless....i will be running nimh at first until i get used to the handling then switch to a 3s....probably overkill.
now common sense tells me ultimately i will have to switch to metal diff cups...but just curious if anyone has a cup racer if they could help.
