I'm making a device requiring a small electric in the Mabuchi 380 or 540 class. In actuality the motor
I'm using is a Johnson brand of unknown model #. It is a similar type to those found in our 1/16 scale tanks.
To my knowledge it is not a 'modified' type but rather a 'normal' in appearance albeit well made motor.

What I'm looking for is performance data for small motors of the type used in 1/16 scale models. Top rpm
at specific voltages without a load would be ideal. I may not find my particular example but any ball park value
will suffice. I'm attempting to determine the performance after gearing of the mechanism I am building.

What am I building? I'm rebuilding and updating a Jochen Maier 3 -speed tank transmission to have a
gear selector mechanism - you can see the progress on my website on the gearbox section under the heading
"Rebuild and conversion of Maier manual 3-speed transmission".

Thanks for any information.
