Savage flux 4s and 25/44

To answer your first question you can definately gear it up by using a larger pinion. However it will put more load on the motor and the batteries. So if you do gear up with a larger pinion keep an eye on the temperatures of the motor and the batteries.

HPI really need to issue a new manual indicating how to correctly regear the flux... Nothing special: larger pinion = more load and more heat...
