ROAR does not allow brushless to race against brushed motor in stock class. And some local track will allow to do so cause that will draw a lot more 12th ppl.
I have seen 12th scale that equipped with 13.5. It is just as fast as the top brushed motor. And if you want to, I believe you can gear it faster then brusheds stock motor if you have the sintered rotor inside.
13.5 motor and GTB definitely going to be heavier...and a lot more wire to cut/zip tie or gue...but without working with the motor and longer run time, BL is definitely what I want to use on my 12th.
Now...beside GTB, I heard Tekin does have the stock motor/speed coming out soon...
