RE: How to hook up all the wires
Going from having nothing plugged in to the RX, to flying the same day, is a bit aggressive. You will want to make sure everything is plugged in right, that all of your throws are adjusted properly, that none of the servos are binding, and that your CG is right where you want it. Follow the manual as to which channel controls which function, and get your throws as close to the recommendations as you can.
And make sure your batteries are fully charged.
Good luck with the maiden!
