RE: best bang for you buck brushed motor on the market.
Kinda agree for a offroad vehicle you are limited in choices seeing the larger tires put a quite a bit of extra stress on the motor.
any decent brushed motor will probably cost close to the price of a budget brushless setup that will blow it away in performance, and life.
Brushed IMO only still reigns supreme in crawlers due to BL generally being too damn fast, and loswer KV motors are more susceptible to cogging(when ran on 2S they seem fine on 3 but kills the point to a low KV motor) from what I've seen
