When I did manage to arm, I could only do it in the non-GPS flight more. I could not arm in any of the GPS flight mode.
Hi, is this a problem or does it have to work exactly this way? I'm not very experienced.
Thank you.

Any mode that needs GPS has additional minimum requirements (there are others that are good but not required):
- properly mounted and configured GPS
- twisted high current cables (ALL of them from battery to motor)
- home location set
- working, configured and calibrated external/aux mag
- INS13 (outdoor/navigation) selected for Attitude Estimation Algorithm
- properly set failsafes (RC and FC) (this is required even for non-GPS flight)

Some of these missing (the ones that can be detected) will keep it from arming, some missing will make it fly away or crash.

Hi, I did not understand this well:
1) twisted high current cables (ALL of them from battery to motor).
2) home location set
And how do I set up failsafe on Turnigy 9X?
Is the home location set automatically? or not?

About failsafe, take a look here and see differences between FC and RC receiver failsafe:

Twist all cables:
- battery to battery plug
- battery plug to PDB (if you have one)
- PDB to ESC
- ESC to motor (3 wire)

Hi, I do not have a PDB, the battery powers ESCs via a multiple cable.
Here's an example: http://www.ebay.it/itm/XT60-to-6-x-3-5mm-Bullet-RC-Hexacopter-ESC-LiPo-Battery-Power-Cable-Hex-UK-/262849589942?hash=item3d330e72b6:g:faEAAOxyVaBS5~lD

Same rule applies, twist all high current (thick wire) cables from battery to motor.  That includes cables in "multiple cable".  :)
