This message is displayed when I arm my quadcopter and increase the throttle without a propellers.
I’m using a high-spec motor compared to the weight of a quadcopter.
Does anyone know why this is happening?
(The grammar may be strange because the native language is not English. I’m sorry.)
That is normal. The copter is detecting that the motors are rotating, but are not producing thrust.
Put the propellers on and the warning will go away
Thanks to you, I successfully completed the flight.
This error was simply the difference between having a propeller and not having one!
