a little question to tax your minds......
doing a little research, a 2000kv motor on 14.8volts using a gear ratio of 9.5 to 1 gives a theoretical top speed of 40mph in an eighth car. i am looking at using an outrunner i have as an experiment as you may have already gathered. motor is 470kv, 6 cell rated, 1100watt continuous, 1300watt peak for 30 secs and has some serious torque. listening to marvins excellent advice in terms of voltage so to start with will try using my 3 2s 3600 25c lipo's in series to give me 3600mah, 22.2 volt. will take up way too much space but if it works can sort proper pack out afterwards. now for the fun bit....at 22.2 volts the 470kv outrunner will need a gear ratio of 3.3 to 1, (which is attainable if you are a loony! ) to get a very similar rpm at wheels as the 2000kv on 14.8 volts. can you forsee any efficiency problems, bit worried the inrush currents to get the car moving may be a bit high, any thoughts??
