Wait, wait. Both servo arms will point either in towards the fuse, or out to the wing tip. They must (and will naturally) point opposite directions. No reversing Y required for ailerons, standard Y Harness is all you need. Just install the wing servos as per the SE Instructions (I've only done 3 of these) and hook the servos into a standard "Y" harness. Plug it into channel 1 and watch the magic.

Don't make a big deal about this for now. We flew for decades without computer radios. Now I'm not saying I'd give mine up now that I'm used to it, but you will do fine without a fancy radio for now. But as stated above, start saveing. Once you get one, you'll wonder why you didn't get one at birth!

Also, let me agree with david. USE YOUR DUAL RATES. Set them exactly as the manual states. When you can fly it all day without problems, you can get sassy. If you set the high Rate to get the most throw possable, the SE will roll so fast you'll have no idea which side is up when you stop! Fun if you expect it, but beware!
