FlySpark turns your Android phone into a complete FPV drone workshop. Plug in your flight controller with a USB OTG cable, or connect over Bluetooth or Wi-Fi, and configure, tune and flash your quadcopter right at the field. No laptop needed.

One app for your whole setup: works with Betaflight, INAV, ArduPilot and PX4 flight controllers, ExpressLRS radio links, EdgeTX radios and BLHeli_S, Bluejay and AM32 ESCs. Built for touch, with phone and tablet layouts.
