If I was the owner, what would I do?

Doesn't castle have a stake in military stuff somewhat? I coulda swore they built some heavy duty controllers for military electric motor applications or something. Maybe I'm thinking Medusa though.

Anyways, if I owned CC, I would take an approach not unlike azjc's. Becoming the Traxxas of the ESC industry would mean tons of money, and more money means more potential to expand into other ventures. So once the company because something of that caliber, I would expand into Electric Vehicle controllers (1:1) and induction motors (1:1). I'd also continue to keep producing new and great stuff for RC cars, boats, and planes, and also possibly venture into some battery technology if possible.
