New style Argos drill motors: A look inside and review

[Roboteernat]

Edit: saw it was a different poster with the above q.

Yohooshi, do you mean the old Argos drill and a new Argos drill?
I do not know the differences in the old gearbox of the previous Argos drill motor, therefore cannot say. If the output speeds vary then your robot will always turn to the slower side.

if the speeds differ, best to get 2 new drills and save the old 2 for a 2 wheel drive bot...

If you mean the old style end cap:
"
It would just be the design of the bit of metal making the back plate, the coils should 99.999% of the time be the same, therefore should be fine."

Past experience with lots of dc 12/24v motors with multiple designs are the basis of my knowledge.
