BL Rockcrawler?

[BrianG]

Even though BL is so much more efficient and requires less maintenance, would a BL design be the best choice for rock crawling? BL motors/ESCs seem to work better at higher rpms. If you gear the vehicle down low enough to avoid cogging at very low speeds, yet get enough motor rpms to be useful, won't the motor not be loaded enough and heat up more? Would a low-kv motor like a 11-13xl be ok, or would a brushed motor be the better choice in this application despite the disadvantages?
