That seem to be a great radio.
It has everything you'll need for a long time ahead, it can also fly helicopters (collective / Throttle mixing).
I have the FF9, but if the F7 had been available when I bought my radio I would probably have choosen it.

The "complexity" is non existing, the Futaba radios are very easy to program and you'll learn all the basic functions in one night if you sit down with the radio, manual and a plane to practice on.

Two things though:
1-- You really don't need the digital servos, as a beginner and with a trainer airplane you can as well use standard 3001 or 3004 servos.

2--The bigger TX battery the better, try to get a bigger TX battery. Sure, if you have a fieldcharger you'll juice it up in half an hour, but it's nice to have a big battery that you don't need to charge during a full weekend of flying.
I run 1500 Mah in my radio and 1500 mah flight packs... No worries!
