I have just replaced all propellers on my Mini (1). I performed a couple of test flights indoors with the propeller guards installed. When using the Litchi app, it reports a short in the ESC shortly after takeoff and suggests restarting the drone. The error persists after restarting. However, when I fly with the DJI Fly app, no such error is reported and all appears normal. I'm going to post on the Litchi support site too, but I'm hoping for comments / suggestions from our experts here. Thanks.
