I just checked out this YT video:
Looks like it is a lot simpler than 4 years ago, and doesn't normally require sensor calibration. The above YT video is only 2 months old.
The requirements are:
With a screen capture on the mobile device do:
Be outside so GPS shows as locked with sufficient sat count.
Do a gimbal calibration.
Show About screen for serial numbers
Show gimbal can go up/down its full range to show it works
Show entire status screen that there are no errors
Continue recording for another 3 minutes in camera view that no latent errors appear.
Much easier than years before. They seem to trust the apps and self-diagnostics. If I were them, I'd include at least CSC motor start at idle, but I suppose the app and firmware would expose motor and ESC issues before even motor start.
Perhaps I could have gotten away with buying refresh after my
M2Z car backover since the only significant damage was the arms but still electrically sound. No way to fly it that way though. But then the repair cost estimate was only about $100 over refresh replacement cost so no loss there when you add the Refesh premium fee.
Insurance is always a gamble with the odds always substantially in favor of the house.
