Hello,
You should not forget that he(it) as well as transports him(it) remain controllable! Because too much power pushes the pilot(driver) has the fault.
It is also necessary to adapt him(it) to the vehicle, the weight, the performances wished etc....

As say ARCT1K, for more than volt, it will be necessary to lower(dim) the KV and to adapt the report(relationship) of transmission.

sorry for my English...
