But is it a good idea to put a differential between the two motors? My
experience with this is kinda bad. I once did something quite similar,
but when the drivetrain was loaded, one of the motors reversed, making
the diff output zero. This happened, BTW, when I geared down the motors
by 3:1 before passing the axle to the differential.
I think you can safely let two motors drive the same gear, without a
differential inbetween. Putting an 8t cog on each motor and a 40t cog
between the two should provide much power. Just make sure you run the
motors in the same direction!
