SCX homeset motor?

[Ramcatlarry]

SCX - 13D size in most current cars of their product with many variations of wind.  A Chinese 16D arm should fit.

SCX homeset motor?

 

Steve is correct (of course!).  It may be wearing a different badge (?) or maybe SCX has different names for them.  They are about the same size as an old Mabuchi FJ13UO, come with mild winds on long stacks and a nice set of pretty strong ceramic magnets.  They're easy to rewind, but also could accept 16D arms with maybe some fiddling to center the arm.  The SCX motors (like RX42B and whatever else they're called) are a good substitute for the old Mabuchi, or even a nice basis for fiddling rewinding.

I put a wasp arm in one. Ran fine, but it could use better brushes and springs.

The magnets are pretty stout on this motor.  I imagine it could  support a #27 wire wind.

[Dave Crevie]

The wimpy springs and brush hoods wouldn't support a hot wind. I wouldn't try anything hotter than a contender,

or at most an X-12.

Sure looks like a work around to beef up or do an end bell exchange would make it a powerful motor, but could see it best used on the drag strip.

This is a current Johnson motor as I understand.  Old 16D (small) brushes.  Guess what - the JK (Hawk-6) or Proslot (4000 series) endbells can be fit with a bit of persuasion
