oh i know, been around forever and good quality stuff, brother in law had a Super Rooster brushless crawler esc and motor, and i had a brushed Novak esc, until they finally died, was just meaning that traxxas had rebadged or at least had castle make/design their electronics as well after Novak...
the velineon at first was castle based, whether they still are or if traxxas outright bought their blueprints or made their own i am unsure.
most of the early velineon had "powered by castle" molded into the motors plastic.
