2. Choosing a Digital Flag

DJI (O3 / Goggles 2)

The king of image quality. It looks exactly like a GoPro feed in your goggles. Best for cinematic pilots, but expensive and heavy.

Walksnail (Avatar)

The most versatile. They make tiny transmitters for 1S Whoops and powerful ones for 5-inch quads. Highly compatible with many goggles.

HDZero

The racer's choice. Fixed latency that matches analog, but with 720p clarity. It's open-source friendly and works great on tiny quads.

3. Frequencies & Pit Mode

Most FPV video lives in the 5.8GHz band. This band is divided into "Bands" (like Raceband) and "Channels" (1 through 8).

Don't be 'That' Pilot

When you power on your drone, your VTX blasts a signal. If another pilot is already flying on that channel, you will **instantly black out their goggles**, causing them to crash.

Pit Mode

A setting that makes your VTX transmit at near-zero power. Use this when working on the bench at a race.

Check Before Powering

Always yell "Powering up on Raceband 4!" before plugging in a battery if others are in the air.

DVR vs. Action Cam

DVR is the low-quality recording of what you see in the goggles (including static). It's your "black box" for finding the drone if you crash.

Action Cams (GoPro, DJI Action, Insta360) are separate cameras mounted on top for high-quality 4K footage.

Pro Tip

"If you didn't record the DVR, did the trick even happen?"
