Fast Blinking Yellow Light

[Top Hat]

Was flying early this AM,everything seems normal except for this,
I think 3 from what I can observe fast flashing yellow light. From the Manual (latest ver) it stated that "Remote Ctlr Signal Lost" (pp 12 "Warning, AC Stat Indicator").
The thing is I can still ctrl the AC and there's no warning notification on the App. Does anyone observed this behavior on your AC?
If so, do you have any idea what it is or should we be worry?
For sure we are aware (for those who already seen this), but what is it?

Check that you have the aircraft switched to RC and not WI-FI that's most likely the issue.

If that was the case, he wouldn't be able to fly it.
The flashing yellow means there is a higher than normal vibration that the IMU is detecting.
Are you using low noise props or aftermarket props?
