Anyone know what would cause "motor current error check your propellers and fly with caution" I checked propellers before flight and they were locked. This error came up after firmware update 4.1.22 (3037) Three minutes into flight drone drops out of sky! Its at dji for assessment, I'm hoping this is warranty and not an insurance claim. I'm now nervous to fly this thing over anything for fear it drops out of sky again. Im not really seeing anyone else having a problem
