Welcome to the hobby.

There is a lot of good and useful information here for a new pilot.
I have the DX6i system and love it. Don't be intimidated by the menu system. Just get into the basics and go from there.
Key items to make sure you understand are reversing controls - if the throttle starts out with the stick all the way down and the control is full open, then it needs to be reversed.. stuff like that.
The other thing to see and understand is end point adjustments - where the controls are adjusted for maximum throw (be careful with this one) and exponential which can be - or + depending on manufacturer. Using this properly will set the sticks for a softer response at the beginning of the stick movement and gets progressively acute as you move the stick to the end of the travel. This allows for soft response of the aircraft for initial stick movement but full response with full response with full stick movement.
The rest of the stuff.. mixing, and so on, can wait for you to get up to speed with the transmitter and the hobby.
Good luck!!
