Remotor for Athearn engines

[MikeGTW]

So looking at some new motor's for athearn I see there is the Kato HM-5 and I also see the Mabuchi SF 266 SA the 266 is very cheap price
and I see on another site you can mount two back to back in a sd45 frame
My concern is the rpm 7200 for the 266 and I believe the athearn were 10-12000 rpm

any other ones besides the original athearn motors

Athearn makes the Genesis version. I don't think I would try to link two motors together unless you know for sure they perform the same.

The motors are not connected one goes to each truck

Even that way, one motor working against the other will make one overheat.

Even back in the olden days of yore wit the double-motored Athearn DD40s, it didn't work all that great.

Any way I do have the "old" athearn DD40 dual motor emd demo unit works just fine thank you
those mabuchi motors are 6 pole and use precious metal for the brushes
