The Ntm 4248 motor does around 12000rpm at 5s and 1300w, good for the given weight and size of the motor. Thats almost half the speed of a gimson or banebots so it's not going to over rev a gearbox.
The problem I'm seeing is that it will probably need a custom gearbox as I have yet to find a 10:1 ish box. If I still don't find one will have to build my own
Another plus I can think of is the relatively cheaper price of the esc when compared to a brushed one.
