Betaflight

Betaflight for iOS is the field companion for your FPV craft. Connect to your flight controller between packs to check it over, tune it and set your video channel. AT A GLANCE Home shows the craft, firmware, board, battery, CPU load and free dataflash, which sensors were detected, and whether it is armed, in failsafe and talking to you. PRE-FLIGHT • See why it won't arm, in plain English, with what to do about each reason • Pack voltage, per-cell voltage, current and mAh used • Receiver signal and live channel bars, so you can check your switches before you plug in a pack ATTITUDE • Live 3D model of the craft, an artificial horizon and a heading indicator • Roll, pitch and heading readouts • Calibrate the accelerometer on a flat surface TUNE • Tune PIDs with the firmware's own sliders, as the Betaflight App does, and see every value change as you move them, or set each one by hand • Rates as sliders, with a live rate curve and the top rate on each axis • Gyro and D term filter sliders, with the cutoffs worked out by the flight controller • Feedforward, D max, lowpass filters and the dynamic notch, per PID profile • Expert mode in Settings opens the full slider ranges • A backup is taken before anything is written, and changes are blocked while the craft is armed VTX • Band, channel and power, with the frequency shown as you pick • Pit mode, so you can power up without spoiling someone else's video GPS • Fix type, satellites in view and in use, and dilution of precision • How many satellites GPS Rescue needs, against how many you have FLIGHT PLAN Draw waypoints on a map, write the plan to the craft and follow the mission as it flies, on firmware built with flight planning. CONDITIONS • A go or no-go verdict for where you are flying • Wind at ground level and at 80 and 120 m, gusts, temperature, humidity, visibility, rain and density altitude • The next few days, sunrise and sunset, and the Kp index for geomagnetic activity • Airspace notices from the FAA or OpenAIP, if you add your own key CLI The full Betaflight CLI, with your most used commands one tap away. CLOUD BACKUPS Sign in with your Betaflight account to keep backups of your craft, shared with the Betaflight App on your computer. Restore one to a craft in a few taps: you are warned first if its firmware, board or flight controller differs, and shown any settings the craft would not take before anything is saved. CONNECTING Connect over Wi-Fi through a network bridge, or over Bluetooth with a BLE serial adapter on your flight controller. Choose whether a dropped link reconnects by itself, so a shared bridge is not pulled back from whoever connected next. Made for current Betaflight firmware. Available in 25 languages. Betaflight is free, made by the team behind the Betaflight firmware and the Betaflight App.
