I think that traditionally rc companies used to be more tolerant of imitation..instead of trying to stop one another from making it, they would change their design in some way to make it stand out from their competitors. Was a more friendly atmosphere back when.. what Traxxas has done is made it more of a business. More cut throat and aggressive. They put patents onto existing products simply because no one else had, and they could. It's business 101 unfortunately..TRX is very sharp in both business and advertising. They've forced the hobby into it's current state. If it weren't them, someone else would've done it for sure..it's human nature. I'm sad that some products have disappeared because of it too, but it is what it is, TRX is just using the system to their advantage.
