Wow, that is some great luck right there. I hate to see another pilot leave the hobby because of crashing (I was once there myself, but stuck with it) but I have to applaud him for donating his stuff to you.
As for the Sat Rx, you will have to plug it in and rebind the system so that it sees the sat. But, your settings should be the same, although I suspect you will be doing a complete head setup once again.
