Hi again, Newbie. (Just thought, what will you do about your screen name when you're no longer a newb?) Anyway, hate to do this, but check your Apprentice manual, top of page 23. It describes what switches do what, and what programming is required. (Dx6i flap switch is default at 0/0 up/down. So you'll have to change those to +100 and -100 respectively.) And ignore the "Dx6" line. That's a different radio than the Dx6i.
And then it says you'll only have 2 SAFE flight modes available. You'll have to go to the bottom of page 22 to set up your rx as to which 2 flight modes you want. Are you up flying mostly intermediate now? Just choose that and experienced modes if so. Good luck!
