Long ferry distance

Dirty ESC

High-density chemical leading to over weight drone

Damaged props

Bad motor

For long ferry distances, reduce the payload to lessen the strain on the electrical system

Keeping the ESC free from chemical residues and dirt can aid in heat dissipation

Carrying a full load of high-density chemicals can overload the drone, causing the ESCs and motors to overwork, which may trigger an automatic landing. Try to reduce payload amount

Using props that are chipped, bent, warped, or loose will reduce their lift capacity, forcing the electrical system to work harder and causing the ESC to heat up more than necessary.

Inspect the motors by spinning them by hand while the drone is turned off. It's normal to feel the ball bearing, but there shouldn't be excessive resistance at any point. Also, listen for any unusual noises.
