.10 .15 370 400, etc.

[Jack_K]

I assume the .10 and .15 mean the motors are similar in power to glows of the same size designation?
However, what does 370, 400, etc. mean in terms of comparison?

370, 400, 480, 500.... etc are based on motor can size of the BRUSHED motor with "roughly" (very roughly) equal power.

Actually, there's very little (almost zero) standardization to motor size labeling.
