Here you go Ben.

If you wanted to order the brushless motor from someone else overseas, other then Leimbach, you could probably take Leimbach's part number and find it in a German hobby shop of your choice.
Edit - I guess I couldn't get a direct link to take you right to the motor, but if you scroll down to their 'Hydraulik' section, you can see the brushless motor listed there. They make a 7.2 volt, and a 12 volt version.
