Indeed, the setup here seems a little 'confused' for what the OP wants to acheive. A 1/5 scale onroad, on 6s lipo, that would be a great candidate for the MMM & 2200v motor- a 2800kv motor on 3s is barely suitable for a 1/10-1/8 onroad.

I would suggest a hobbywing 150amp esc, ~1600-1900kv XL motor and 6s for a fast setup, bit cheaper than the MMM and should hold up alright.
