If you are talking "ROAR 4X4 SCT Legal" (Newish designation on their Approved Brushless Motors chart) then no, they are not. The 1415 motor is 1:8th legal, and the 1410 is "modified" legal...
RC Pro Series will allow it, as 4x4 SCT is an Open class. Most local clubs will allow it as well. Heck, you could cram an 8th scale monster in there if you REALLY wanted to...There IS such thing as "too much" power.

Slightly more efficient, since the motor is unsensored...not as smooth, especially on the low end...cannot take advantage of some tuning options... Even the 1410 has more power than we can put down through 90% of our large 8th scale track.

If you're looking for good performance, lots of power, and relatively inexpensive, they are good. A friend of mine runs the MMP with a Novak 5.5T 550 and a savox high voltage servo. He had to use a stand-alone BEC for the servo because even at the 6V that the MMP can output, the current draw was causing major issues.
Just bear this in mind: Castle is focussed where 80% of the RC market is. Bashing. Where "More power is more better" and there are no rules to be worried about.
Clear the motor with your local track's race director for club racing, use it at RCPS events, but be advised that it will likely not pass tech at a ROAR sanctioned event.
