the 17:31 can lower for power consumption !
But is not slow more than 19.31
so i use that...
IT'S Because If I use the 19:31 my aaa-mh always Can't to keep 10 min at optimum state!
(around 7-min) "the best state"
i Know 19:31 is best/high-speed More than 17:31...
but my motor Will use high power consumption ....
i want to keep the lower power consumption to enough still optinmum state to last 3Min =])So I use the 17:31
~SORRY~MY ENG IS NOT SO GD~BUT I CAN'T TO TYPE CHI AT THIS TIME ~ X__X ~XD
