Imo weight is too unreliable to make the comparisons we’re talking about, different shafts, motor cans and all sorts! Air gap is probably just another factor to consider.
@hummieee do you make motors other than your DDs??
@Pedrodemio Set up a thread directly for the discussions we’re having, a compendium of motor testing (linked). I will try to perform the same so we can add more to the mix.
It’d be immensely useful to create a direct comparisons of motors.
