Hi, everyone!
At the last week I've got Iris by post. I've read all manuals. And I've decided that on the way to me (from USA to Germany) IMUs could be untuned and I must to calibrate sensors before flying. I've installed the Mission Planner, connected Iris to PC and conducted total tuning the quadcopter. Mission Planner has said that tuning was successful. IMUs display correct information by hand moving the quadcopter. But when I went to fly, the maximum altitude that I've got was 1 meter!!! I've pushed throttle stick against stop and nothing happend. I've already slightly damaged the props although even didn't fly.
Before fly I watched battery voltage in Mission Planner and it was on fine level 12.2V.
After one of firmware reloading has been changed the arm motors. Before it I held the left stick back-right until the motors spined at low speed, but now I hold the stick back-right, after that Iris tones and nothing. But when I move stick up - motors starts one after another.
Please, help me! I have quadcopter but I can't fly. It's not cricket!!!

Problem has been decided! Propellers must be installed writing on propellers faces up! I'm stupid ass.
Thanks everyone, who answered
Thank you, Chris Anderson, for the answer:
"the short answer to your question is that it sounds like your ESCs have become decalibrated. Please go through the calibration process here: http://copter.ardupilot.com/wiki/initial-setup/esc-motor/ "
I've done calibration. And has been changed only the arm motors. Now all motors by left stick back-right spined together at low speed. But rotaion velocity is too low and I've got only 0.3 meter above the ground.
Sorry if this sounds really dumb, but have you tried calibrating the radio and then removing the props and increasing the throttle to 100%. You can hookup the APM to your computer and in MissionPlanner on the first screen tick the TUNING BOX. Then graph stuff like throttle, and the individual motor outputs. Make sure the motor outputs go up as you increase the throttle.
Thanks, mP1, for answer,
I've done this steps 1 million times, motor outputs go up as I increase the throttle, but one go up higher, other lower and it loks like stairs.
I've tried to do setup many times and nothing. And I think that problem is either of Pixhawk setup or of ESC. I'm facing a sentence of 3d robotic expert technicians.
P.s.:May be I need just to sacrifice to the gods to Ready To Fly quadcopter fly? :D
Do the motor outputs go up equally when you increase the throttle. Im not talking about what you see but what the APM is asking the motors to do.
