Using a mini wireless controller with arduino

So I have a project in which I'm using 4-5 servos that I'd like to be able to control wirelessly. I'd like the wireless controller to be as small of a form factor as possible. Something like the Acgam R1 would be perfect, but it seems like getting it to interface with the arduino isn't very straightforward.

Is building my own going to be the easiest option here? And if so is there an example project that I might be able to get some inspiration from? All I've found are tutorials on making game controllers which isn't what I'm looking for.

That controller is Bluetooth, so it can interface with the Ardiono. Your challenge is to discover (user manual?) the data stream possibilities then just use something like a switch statement to invoke whatever action(s) you want for each button/data stream. You might try to find some code to just read the device and print the data you receive for each combination of buttons.
