I've seen threads where DJI has recommended the replacement of propellers for the Mavic every 200 flights, but has there ever been a comprehensive maintenance schedule to include motor and airframe hours?  I'm looking to acquire a 107 certificate and start my own business and currently have a mavic for hobby purposes.  For future planning, I do want to understand the cost of maintaining any of DJI's drones in a fleet.

Thanks!

See this thread on 2,000 miles flown by Sparksbird.
He should be able to provide you with some good info on maintenance scheduling.
