Hi,
Any advice on where I can purchase just the controller for Mavic Pro and what they cost?

Hello MacIak, since we don't sell the Mavic controller separately, you could purchase the controller thru eBay or reseller.
You can find a reseller in this link: http://www.dji.com/where-to-buy

why would you want a controller on its own? have you found a Mavic pro flyaway?

Hi, yes i have the mavic for a while now. I need the additional tx as a testbed to do some long range modding. The standard tx i will use for portability.
