The general masses have yet to get these into their hands, but from previous examples of 4 magnet (Mod) motors I would expect the following.

More than likely the change to 4 magnets will shift the power band up higher in the rpm range. Most people are already looking for more Torque in the MS, so in TC it could be a problem.

The MS Armature has very few lamination as it is and examples with little or no balance holes tend to make more overall power. With no drill holes, power from sample to sample should be better.

It will be interesting to see how long it takes for these new Motors to make it to the mainstream Hobbiest (if at all) and what people really think of them.
