RE: trainer set up
No, that stuff comes with it. They are just using the same specs that they use for the ARF version (In other words, it's a screw-up on the web page)
BTW, there are two more expences you need to consider.
1) AMA Dues
2) Club Dues
From the way you are talking, it sounds like you're going to try to do this on your own - Don't
If you do, your $250 investment will be a pile of splinters in about 7 seconds after takeoff.
Find the club in your area, they will be happy to help you out
