RE: reciever question
Kittycat,
Have you bought your radio yet? If so most of them come with the drawing you’re looking for in the manual. It's really a pretty easy setup, the JR receivers have labels that tell you which servo plugs in which slot, the other brands might also but I don't have any experience with them. I'm not sure what type of safety items your referring to, the best thing I can think of would be a Hobbico Voltwatch (on all my planes) that tells you the status of your battery under load while the plane in on. It plugs into a spare channel on your receiver and has LED's to indicate battery voltage and will let you know if your battery is low or you have a servo with a problem draining your battery faster than it should. I don't have a scanner but can take a pic of the page in my manual with the radio layout if you like.
Knightmagic,
I would use separate channels for the ailerons and skip the Y harness if your radio has the ability to do it. It's an added cost (the y harness) and another component in the system to have a potential problem. Setting up the flaperons should be a pretty simple procedure, and the manual that came with your radio should fully explain it. Like the others have said it never hurts to learn something new. Isn't that why you buy a computer radio in the first place?
