"Motor idling (loose or missing propeller)" warning question

[rocketflyer]

Haven't had a chance to fly my new bird yet, only calibrated IMU and gimbal - compass calibration to be done when in the field.

I have a question for other owners. I armed the motors (with no props attached) to check for odd noises coming from the motors (all seemed fine). When I gave it a little throttle I got the warning message in the DJI Go app as in the thread title. I read somewhere that this warning will go off in this particular circumstance. Is this correct?

Yes...applying throttle without props attached will bring up that warning.

Since you had no props attached, I don't think it's much of a mystery that it said "....missing propeller".

Many thanks for the quick reply!

Lol this is indeed true, however, coming from a P3S which is way less complex it caught me a little off guard. I originally assumed that the P4 simply did some comparison of current draw between the motors in order to come up with the warning but I guess it's a bit more sophisticated than that.

Accordingly DJI, checking engines at iddle is the way to do. They did a video where this is explained

Thanks, did its maiden flight a few days ago which was completely uneventful
