I am the owner of a new Iris+ and I have been doing my best to take it slow.
When I went out for my maiden voyage, I tried to arm the Iris+, It would not arm, so I tried arming the Iris from my tablet and it returned the following error:
"ARM THR below FS"
I assume this has something to do with the throttle and fail safe, But that's all I can guess. Im not sure how or why this is erroring?
There were also error messages about compass inconsistencies. I will try to fix one thing at a time.
Thanks for your time

You may also consider joining the Iris group for any Iris specific troubles or questions you may have.
I am in the air. The first flight went well. Almost had a grand error by loading the wrong mission into the droidplanner.
Luckily for me the direction it headed gave me time. I almost panicked and I hit return to home. It came back, I realized what I had done. As cautious as I was. I need to be more aware.
So then I reloaded my mission for the area I was at, sent it off and it did its thing.
WOW. Im hooked. One last thing I need to fix is battery but ill post that in iris forum.
thanks again
Glad to hear you got it figured out!
After re binding the transmitter I plugged into mission planner and got several fail safes.
One was a bad velocity. So I re calibrated the accelerator and the compass.
The compass instructions here: https://www.youtube.com/watch?v=oD9Z9IR2TNU
seemed to allow you to choose when to exit the calibration. When I use mission planner 1.3.11 to calibrate gps, after a certain amount of turns, it autofinished and told me my new parameters.
After that I tried to arm the engines again, this time error was High GPS HDOP. This was resolved by going outside of the house with the Iris. I was troubleshooting indoors.
I am setting up to maiden voyage. Transmitter is working against Iris motors and I can successfully arm and disarm from the transmitter.
thanks for your time a great help.
One bit of good news is that within mission planner I can go through controller calibration now. The graphs respond to the transmitter sticks moving. It still seems as though the transmitter is not talking to the receiver.
I tried rebinding the transmitter to the receiver. Although I had a green light after the process Im still getting a yellow flashing light.
This should help you get a start on what was keeping you from arming your Iris: http://copter.ardupilot.com/wiki/prearm_safety_check/
"Check FS_THR_VALUE : the radio failsafe pwm value has been set too close to the throttle channels (i.e. ch3) minimum."
You may have your throttle failsafe pwm value too close as the pae says, or it may be that your RC controller is not properly calibrated. Very easy to calibrate, all you need to do is start the calibration and wiggle all the sticks around.

And after sorting that out it may be a good idea to calibrate your compass for where you are, since it changes as you move about the globe: http://copter.ardupilot.com/wiki/initial-setup/configuring-hardware...
When Im in mission planner and connected, under mandatory hardware, radio calibration.
When I begin the calibration, nothing moves when I move the sticks around.
It seems now I get a consistant loss of RC signal, indicated by the flashing yellow light.
Does the iris respond to anything you do with the radio? for example, switching flight modes on the rc controller lead to a change on mission planner or droidplanner to that newly selected mode? You may have to pop off the top shell of your Iris and see what the RX is doing. maybe its not plugged in, maybe it needs rebinding to the TX. heres a vid for binding with the original Iris, should be the same for the new Iris+

Do you know what the usb cable is plugged into, other than the Iris? Or does it matter?
