First Flight Blues

Took my new Iris + out for the first time today. I had checked everything out on the bench before I left home so I expected a carfree flight.  should have known better!

First flight was supposed to be in loiter mode - Put the battery in, moved it to the ground about 10 ft away. Pressed red button on top (it became steady, and stood back. Pulled throttle down to the right and.... nothing. 

I tried the follow me mode. I armed it from my cell phone and it took off and hovered at 10m and then followed me as it was supposed to do.  I engaged the RTL and it landed within 6 inches of the takeoff point (That was impressive.)

Put it back on the table to change the battery (hard to close door with battery connected) and then moved it to the ground again.  Set up a mission and when I went to arm it, the cell phone said there was a gyro calibration issue.  Unplugged battery and reinstalled battery - same issue.

I took it home, put it on my work bench and now everything is fine.

My question is "what causes a gyro calibration error and how do I fix in the field?  Any ideas why it wouldn't start in STD or Loiter mode?  And why would it start in auto to follow me and not in any other mode?

  • I'm pretty new to the Iris+. I have had about 5 good flights with mine and today on a takeoff it flipped over on some gravel, dinging up the propellers some. Cleaned it up and tried again on some grass and it flipped again. Tried a third time and it took off fine. Thinking back, I may have lifted the front to turn on the GoPro (not attached Gimbal yet) and this is when it flipped.

    Maybe you connecting the battery then moving it, has something to do with it, like my crash?

    • I think I am too anxious to get started.  With the DJI 550 I had, I could plug it in and then place it on the ground and wait for the 20 rapid flashes. The Iris is more sensitive.  Here is what 3 DR told me.:

      • When the Iris+ is turned ON you will see a flashing Red/Blue light sequence, this is the Gyroscope calibration, on this sequence it will acquire gyroscope stable values, if the copter is moved around or it's not on a stable surface you will acquire bad gyroscope values and will get a Bad Gyro Health error, to avoid this just turn on the Iris+ on a stable surface and don't move it around until you see the flashing green lights.
