Hi,
For the different stick-modes, check-out here :

The best stickmode is the mode in which your master will learn you to fly, be it mode 1, 2, 3 or 4.
The easiest stick-mode is mode 1 or 4, where main function up/down and turning (ailerons) are on a separate stick (except for heli).
As said before, your 9C can easily be changed from mode 2 to 1 or vice-versa :
1) change in program AND
2) inside change a spring on a stick (or even easier with a piece of plastic to move from one side to the other by unscrewing 2 screws.
