That website is the site of the XTR designer. His name is Wolfgang. MRC is the importer and distributer of XTR for him.
By the way, Wright, theres a problem from what I understand with the Hitec Eclipse 7 and XTR. Seems like Hitec changed the pin configuration on the trainer jack of the Eclipse 7 without tellin anyone, so XTR won't run. A simple resolder job will fix the problem, but I think MRC is coming out with another cable or something to solve the problem.
