About these "Flyaways" altitude goes negative.

[Frank508]

I've noticed in 2 of the videos posted on the other forum that the altitude number goes negative in the video.

For the folks that have had this happen, were your altitude numbers off too?

In this thread on the other forum...

the poster mentions that the IMU Calibration is not mentioned in the manual. I thought he must be wrong, but a word search for IMU has one mention of this and it is in the decoding table for the indicator light - that surprised me. I'm sure I read about it somewhere.

Probably here, hundreds of times. The calibration is not meant to be done unless it is out of spec and that should not happen very often. This is why it is under "advanced settings."
