thank you Dan Vector for the reply, our class has a 540 can size and 2s lipo limit like a mod touring car but thats about the only limitation ,we run wide foams ( super barchetta ) and lola bodies which provide our cars with an extraordinary amount of traction and thus excess current draw, yes 1/10 esc's can handle it but most of us run larger more robust esc like for example castle mmp and tekin rx8, the tekin has proven to run the same motor cooler and faster the the mmp and other esc like hobbywing xerun 120a, it is worth about half a second a lap, my castle mmp has been a faithful workhorse but is outclassed and a limitation next to the rx8's and i am about half a second down on the fastest driver ( rx8 equipped ). the rx8 is cheaper or line ball with the rs pro as well as tougher and it will be the way i go next unless the rs pro has some other advantage besides being smaller, i dont know the answer to this question which is why i have posted here so if there is any other difference it would be great to know.
thank you for your time
cheers
