B-2 motor != N20 mabuchi?


I have always assumed that the motors used in the Watt-age B2 were the same as the N20 motors. I have a reliable source that explains that these are not the same.

Can anyone give more information on the differences?

Here is the B2: http://www.hobbypeople.net/gallery/128400.htm

Here are the motors: http://www.hobbypeople.net/gallery/128470.htm

Here are the N20 motors: http://www.allelectronics.com/cgi-bi...166&type=store

Well, I'm using those exact motors from allelectronics as direct replacements for the B2 motors. Working fine so far.

Thanks for that data point. Do the motors look identical? Do you notice any reduction in thrust?

A quick look at the endbell tells you that they are not N20.
The thrust is similar but the N20PN pulls almost twice the amps an gets hot as compared to the B2 mystery motor.
The N20PA is anemic.
The N20s have wire brushes. B2?

Yes, frankenfoamy is correct, I just compared the two motors and the B2 motor is not the same.
