A Part 107 certificate proves you know FAA rules. It does not prove you can fly well enough for paying clients. Skill-building happens separately, and it matters more than most new pilots expect.
Basic flight control
Before doing any paid work, you should be able to: take off and land precisely in a small space, fly a consistent rectangle at a fixed altitude, orbit a fixed point smoothly, and execute a slow pull-back reveal without wobble. None of these are advanced maneuvers. All of them are things clients will notice if you do them poorly. Practice in an open area for at least 10 to 15 hours across multiple sessions before flying for clients.
Camera operation and settings
Flying the drone is half the job. The other half is capturing footage that doesn't need an apology. This means understanding: how to set manual exposure (ISO, shutter speed, and aperture on variable-aperture drones), when to use ND filters, how to frame shots using the rule of thirds, and how to execute smooth, intentional movements rather than jerky repositioning. DJI's QuickShots (Orbit, Dronie, Helix, Rocket) are useful for client demos early on, but clients in real estate and construction want stable, purposeful camera work, not preset tricks.
Flight planning and airspace awareness
Before every flight, check the airspace using LAANC through the FAA DroneZone or apps like Aloft (formerly Kittyhawk) or AirHub. Get comfortable reading B4UFLY and UAV Forecast for weather conditions. Knowing how to get airspace authorizations for controlled airspace (LAANC) is a practical skill that opens more markets, since urban real estate work often requires authorization in Class C or D airspace.
Note: DJI's simulator mode in the DJI Fly app lets you practice drone control without using a real drone. It's limited but useful for building muscle memory with the control sticks before your first outdoor sessions.
