The specs seems pretty awsome.
It's not the same motor, but this one is comparable.
Yep, those are really good. They are better than the 5010kv 360kv motors due to two factors; less resistance and higher W (if the numbers provided are correct).
These guys have a better price for the same motors;
Those are the ones I'm testing first. Got an order in for some huge props for this, going to be interesting to see if they will even spin. I also got some 15" CF props on order just in case. Do you know how many mag poles these motors have?
I only have the W48-22 490kv version. So far they look very good, but I do not have any run time on them yet. 22 poles and you can see/feel/hear that they actually have been properly factory balanced.
I had no problem spinning up the CF 15x55 using 4S and a TY-P1 25A ESC with SimonK firmware, and no excessive heat either from motor or ESC.
