The RC-Monster Slipperentials was designed and developed by RC-Monster and another individual who sold all rights to RC-Monster. The counterfeits are the reason for the warning about counterfeits on the RC-Momster home page. There's also a thread there detailing all of it.
As as for the Castle and Sirrus purple copies (I remembered the name) there is also a thread about it on RC-Monster where Castle has their own subforum where the founder and CEO along with a couple other reps post. There is also a closed thread on ModelsportUK about it where ModelsportUK, Sirrus and Castle all posted. Last I checked Sirrus changed the can design slightly but still used the same exact dimensions, kv ratings and size nomenclature (ie 1515,1717 etc) as Castle. There's also a thread on RC-Monster detailing the wholly owned and controlled Castle subsidiary and factory in China. Castle only makes Castle motors and the ones they rebrand for HPI, Traxxas, not sure if they still make motors for Duratrax and Dynamite as I don't pay much attention to the 1/10 stuff. Either way Castle is the OE, they don't sell their designs and in fact they actually pay Steve Neu to use his designs in Castle motors.
