What numbers are you in need of? I did a mbx5 conversion to on-road and I have it set up to do 60 or so and I can run it around all day with no worries. My set up is cc2200kv mmm esc on 5s w/a20T pinion and stock spur which I don't recall at the moment. I know I could gear higher for faster speeds but I want to keep my motor in one piece. On a 6s set up the motor would spin at around 46K+ so it wont last long at that set up but good for short runs....the speed calc estimated around 80+mph
