Cox (AKA Cox Models) is a brand of remote control hobby products that is owned and managed by Hobbico, Inc, of Champlain, Illinois in the USA. The brand's website (www.coxmodels.com) offers a nicely done write-up of the company's history. Here is a short excerpt:
The company was founded by L.M. "Leroy" Cox in 1945. And from the start, the company's success was due as much to high product quality as his genius for offering innovative, practical products at entry-level prices. His standards were strict, and required the development of one-of-a-kind testing and manufacturing equipment. Legend has it that a piston/sleeve just 25 millionths of an inch out of tolerance was considered unacceptable.
Read the whole thing for a snapshot back in RC history. The Cox brand is one of the foundational brands of the RC hobby industry.
The Cox brand was acquired by Hobbico in 2010 with the goal being:
to bring back the fun and excitement that the Cox name and products have always inspired.
With inexpensive Ready-to-Fly starter packages like the Sky Cruiser, Sky Ranger, and Extra 300, the brand is well on their way to doing just that.
Cox branded products can be purchased anywhere that the Hobbico umbrella of products are sold.
