I consider myself an expert. Able to troubleshoot my issues but I'm very humble in the fact that I can learn something everyday. . I have green gps lock and I can only arm in stabilize and when I switched to loiter it drifts. .. Please help.

Heck. I've only flower it 2 times... lol I will look at everything to suggest thank you

Definitely set it all back to zero. No matter what else may or may not be wrong, it can not function with transmitter trim not zeroed. Drifting in loiter can be caused by vibration, GPS problems, compass problems, or poor tuning.
5) Follow the Auto Tune instructions here to see if it improves upon #2's manual tuning: http://copter.ardupilot.com/wiki/autotune/. Compare against your manual numbers you wrote down. Note and save for future reference.
You shouldn't be trimming anything while in normal daily flight. You trim it for your designed and built weight and balance once using the SAVE TRIM function. You must do this with no wind for obvious reasons. Once you do that once, the trim is saved in the flight controller and your transmitter should be at zero trim.
You definitely do not ever want to be using transmitter trim while in loiter. Bad bad bad. Remember, zero pitch, zero roll, zero yaw, and zero (mid) throttle in loiter mode is telling it to hold still. If you add transmitter trim, you are no longer at zero, and therefore are commanding it to MOVE, not hold still. Likewise, having any transmitter trim in stabilize mode will also be commanding it to pitch/roll/yaw. With the controls at zero, the flight controller will level itself. If you start adding trim, you are again commanding it to MOVE and it will never do what you want.
Hence why you MUST use the SAVE TRIM function noted above to trim it out once and be done with it. You can not have trim set on your transmitter. Nothing will work properly if you do that.
Also, absolutely no tuning, trimming, or balancing will work if your vibration is too much. You need to address your vibration before you ever leave the ground or nothing will work right. http://copter.ardupilot.com/wiki/ac_measuringvibration/
I would think since it is an Iris, vibration is already taken care of though.
Btw chris anyway I can buy the the IRIS gimbal mount.. I created a ticket for the loiter function not holding altitude and I broke legs? Props, and the gimble mount. .. I need the iris gimbal mount
If I did not add trim it keeps drifting... I had gos lock.. I just got this thing... I'm trying to look at logs but it's a different language to me.. maybe the gos lock is not strong enough?

1) Verify your GPS is installed and operating correctly: http://copter.ardupilot.com/wiki/common-installing-3dr-ublox-gps-co...
2) Verify your compass is calibrated and declination set: http://copter.ardupilot.com/wiki/initial-setup/configuring-hardware...)
3) Follow the vibration testing instructions here: http://copter.ardupilot.com/wiki/ac_measuringvibration/
4) Follow Dave's manual tuning instructions here: http://diydrones.com/forum/topics/arducopter-tuning-guide. Write down the PID values you come up with for future reference as well. You can also save the parameter file.
5) Follow the Auto Tune instructions here to see if it improves upon #2's manual tuning: http://copter.ardupilot.com/wiki/autotune/. Compare against your manual numbers you wrote down. Note and save for future reference.
6) Follow the SAVE TRIM instructions here: http://copter.ardupilot.com/wiki/autotrim/.
I did all of the above in that order and my quad is rock solid. It was not before.

Are you sure you are selecting the right mode?
Don't add any trim, the flight controller will keep adding it.
Maybe have a look around the new support forums for answers as well, log file questions
