How to Fly with other FPV Pilots (Channel Management)
I'm working on adding some content here, channel charts, group scenarios, etc If you have content to add, or suggestions, please shoot me a message on Instagram @FlyHighFPV
DJI Hack Files:
Install these files on a MicroSD card and boot up your goggles one time with the card inserted and the mod will be applied. Keep in mind to follow your local regulations, and have a HAM license if you want to legal push 1000mw or higher.
OG Air Unit and Vista on V1 / V2 goggles:
1200MW Mod - This one lets you use full power
FCC Hack - this one puts your goggles in FCC mode for use in the USA
03 and 04 Air Units for the V2 Goggles, G2, Integra, and G3 Goggles
Scenarios
1-3 Pilots at one time:
If you're flying with a small group of pilots, generally you can get away with everyone flying full power, with 3 pilots at a time. If you're flying on DJI or WalkSnail, crank up the bitrate from 25mbps to 50mbps, or from 10and 20mhz to 40 or 60mhz to get up to the wide band, where you have 3 channels. If you only have one channel listed, you need the HAM file listed about on your goggles.
You can mix DJI and Analog and HDZero, if you're careful, and you understand how the Raceband overlaps with the 50mbps bands from DJI/WS.

The 3 big channels on the bottom row in purple, are DJI's wide bands. The Raceband in Black shows how Analog overlaps with 50mbps. so DJI1 will cover Race1,2, and 3. DJI2 covers Race 3, 4, and 5, and DJI3 covers Race 6 , 7, and 8.
So if Analog and HDZero Pilots want to fly with DJI wideband, they can just use the Raceband channels 1, 4, and 8. For example you could put DJI on 1 and 3 and have Raceband 4, in the middle of them. I always prefer to put Raceband on 1 for simplicity, and DJI on 2 and 3.
Managing Flight lines at events
If you want to run full grids with multiple pilots, you're not going to be able to hog the sky with widebands, so everyone will need to turn down their bitrate and their power levels. DJI and Walksnail should be on 25mbps or the lowest mhz they can, like 10 or 20mhz. Depending on the separation between flight lines you may need everyone to turn down their output power to 25mw, but in larger spots with more separation, 200mw may work well. Next we split up the Raceband into Odds and Evens so that we have 4 channels on each flight line, with separation between each one. If there are alot of pilots on site, we'll split up flights per video system, so that DJI pilots fly together, Analog separate, HDZero, etc. The dJI and WS systems mix together the best, and Analog and HDZero also mix well if you dont have enough of a system to fill up a flight.
I've developed a magnetic 3D printable system for organizing pilots with hangtags/dogtags and made it open source for the community to use. It uses interchangeable tags for the video systems, cheap hooks and magnets so the flights stay together, and are easily dumped. We've been making Flight Line Boards for years, traditionally CNC'd or chloroplast in hooks, but we're continuing to evolve the solutions.
If you are running Bambu Labs, just grab the 3mf project file, and the layouts will already be setup for A1 with AMS. Otherwise, I'd grab the zip that contains the STL's
Supplies:
I printed mine with PETG
There are also online systems like ZippyQue that's commonly used by racers, but this one works without internet connectivity, designed to be printed on Bambu Labs AMS.
