I am a newbie trying to learn the techie stuff.
I have acquired several minis, some clones(?). I have noticed that three of the units I have have white, 10(ten) tooth pinon gears, the rest of the gears on each unit are also white. The name on the trans. is 'Bensii'. The other units I have are a 'Bit" and a MicroSizzler, +, they all have either green, 6(six) tooth pino gears or 6(six) tooth, black pinon gears, the axels have colored gears signifying there ratio.
What is, if there is a significance, of the colors? Please help.
