Lower number equals lower wind. Lower wind means faster motor. Look at the kv number which is rpm per volt. You want to run your motor at a max of 35k rpms. This helps keep the heat down. Multiply the voltage battery you wish to use by the kv to get a motor rpm figure and try to stay below 35k rpm. Such as 14.8v x 2200kv = 32500 rpm = good. And then gear your truck to the speed you will want to run at. I gear all of my stuff to around 40mph cause it suits my drving style and area I play in.
