It should come with a bind plug. If it doesn't, just take an old servo and cut the plug off of it then remove the center wire, and short the other two together. That is all a bind plug is.
Make sure it comes with the satellite Rx as well. It will greatly reduce your chance of a brown-out, or losing signal.
And I'm sure you just mistyped it above, but it's an AR6210. So I take it your going to make the jump to the DX8?
Yes before I got my DX8 I had the DX6i which requires you use the AR6210. I mounted the AR6210 on the side of my trex 450 near the tail servo. I should rewire the thing to use the 2 sattelites now that I have the DX8. But since it works just fine I haven't messed with it.Okay, so will the AR6210 fit the 450 pro size wise? The align one looks like a very tight fit. Cheers
