Carrying which spares best supports field maintenance readiness for a typical small unmanned aircraft operation?

• A.A spare aircraft registration number to apply if one is damaged
• B.Paint and decals to repair structural cracks cosmetically
• C.Serviceable spare propellers and charged spare batteries, plus basic tools recommended by the manufacturer

Why

Propellers are the most commonly damaged part and batteries limit operating time. Having inspected spares and basic tools allows a damaged propeller found in preflight to be replaced properly instead of flown.
