Amazon's referral values always ends with "-20" and is usually placed under the parameter "tag". OPs link doesn't have any referral attached to it. For those who aren't familiar with Amazon's links, it may be hard to figure out how to detach it while still keeping it valid.
Sorry about that, I quickly copied a link from my wishlist and didn't look to clean it up. No referral link intended.
If you can crack open the controls and connect a board to it you could technically hack it. If you're on about with it's own firmware / sdk then that's a slightly different story. I've seen controllers being re-purposed (though not yet seen a drone's controller)
