, Nico71 (Nicolas Lespour) shows "A simple assemby to test different BB [battery boxes], based on differential principle.

-- If the yellow part turns clockwise, the slowest motor is on the right

-- If the yellow part turns anti-clockwise, the slowest motor is on the left

Very cool! This would definetly help me. I hope they make instructions for it though.

Hello, do you need instruction ? Because I make the video to show you how to build this but if you need some other picture, I can do it :)

As Zblj has pointed out : you can also compare two identical motors with pluging the two motor on one battery box. :)

I would also try running both off one battery just in case one motor runs slower than the other. It would be annoying for that to be the problem.

Yeah, it's a good idea but you'd either need to be sure that the motors are identical (are they normally? ) or repeat the test with the motor reversed just to be sure.

Excellent work :)
