I'm very disappointed with my Iris+. I managed to get less than ten minutes flying time before it crashed. Whist on loiter mode one of the motors suddenly lost thrust causing it to fly uncontrollably toward the ground (Lucky it didn't head toward me!)
I can't work out for the life of my what caused it??? ESC, motor?? I have temporarily glued the arm back on with CA to in order to test the motor.
I have been seeing the dual blinking yellow lights a fair amount and have noticed post crash gyro, baro, accelerometer issues (ie. spastic gyro and a message in mission planner saying bad gyro error).
I have attached the .bin file and a couple of videos showing the motor issue, I would appreciate any suggestions?

Dang John that sucks. Sorry to hear.
I'm no expert but have had plenty of time to
experiment and get to know my Iris v1.
I recall i once had spastic motor behavior after
not properly calibrating my radio. Obviously if that
where the case with you that would be 3DR's error & quality control issue.
By the looks of your video, it looks like the behavior starts at or just past 50% throttle.
That's how mine behaved as well and returned to normal after lowering throttle.
My Iris is suffering from a sticky motor start up too.
The crash may have affected the motor performance.
My front-right has taken two solid crashes and is also
the sticky one.
Pick up your Iris and give the props a spin.
My sticky motor sounds a bit dry and like it's
got a bit of pressure on it.
Cheers Oscar,
I gave the props a spin an noticed that the defective motor provides less friction than the other motors. 3DR are looking at replacing the unit which is good.
