Routine drone maintenance

Every flight: inspect props (nicks = replace), check motor spin by hand for grit, wipe sensors and lens.

Every ~20 flights: check arm hinges and screws, look for cracked frame parts, clean vision sensors with a microfiber cloth.

Firmware: update aircraft, remote and batteries together. Read release notes before an important job — don't update the night before a shoot.

After sand or salt: blow out motors with an air blower, wipe the shell; salt water exposure needs a professional inspection.

FPV builds: check solder joints, XT60 security, and that the antennas aren't touching props.
