This was included with a Traxxas, Kyosho or Tamiya kit (can't remember which) from the early 2000s and never used - an electronic speed controller was used instead so this was put away for storage, but now it's time for a new home!  I think these are fairly generic and should work with most applications but please research before purchasing.
