Why ELRS Mobile?

Real-world solutions for the field and the bench.

Problem

The "Dead Zone" Mismatch

You're at a remote bando and realize your TX is on v4.0 but your RX is on v3.3. No cell service, no laptop, and no way to reach the Web Flasher.

The Fix: Open the app, select your cached target, and flash via Wi-Fi. Back in the air in under 60 seconds—zero bars required.
Updates

Mass Configuration

Changed your home Wi-Fi password or SSID? Bringing ten aircraft to your PC just to update a text string is a massive chore.

The Fix: Bring your phone to the fleet. Connect to each quad's AP and update network settings or binding phrases natively and instantly.

Flash from local cache instead of waiting for web downloads or cloud compiles.

📡 Reliable Anywhere
