The SpeedyBee F405 WING APP is a full-featured fixed-wing flight controller stack designed for pilots who want serious INAV capability with wireless tuning and integrated LED control. Running INAV on an STM32F405 processor, it supports conventional fixed-wing, V-tail, flaperon, and VTOL configurations with 12 PWM outputs. The included Wireless Board adds BLE and Wi-Fi tuning via the SpeedyBee app, plus a 4-channel WS2812 LED strip controller for custom lighting effects — all in one package. The integrated PDB handles 2–6S input with dedicated BEC outputs for FC, VTX, and servos, and a high-capacity 90A / 215A peak current sensor. Contents Key Features Compatibility Specifications Package Includes Related Parts & Collections FAQ Key Features ✅ STM32F405 + INAV Ready — Runs INAV firmware (SpeedyBeeF405WING target) with full fixed-wing and VTOL mode support. 12 PWM outputs (11 motor/servo + 1 LED pad) cover conventional, V-tail, flaperon, and VTOL layouts. ✅ BLE + Wi-Fi Wireless Tuning — The included Wireless Board connects to the SpeedyBee app via BLE or Wi-Fi AP mode for field configuration without a laptop. Long-press BOOT for 6 seconds to switch modes. ✅ 4-Channel WS2812 LED Strip Controller — Onboard LED strip controller supports 4 WS2812 channels with adjustable colors and flashing modes. Supports up to 70 pcs 5050 WS2812 beads at 5.2V / 1.3A. Short-press BOOT to switch effects. ✅ 4x RGB Battery Level Indicator — The Wireless Board features 4 onboard RGB LEDs that display battery level by number of lights — a quick visual check without opening a configurator. ✅ 6× UART Ports — UART1 for ELRS/CRSF, UART2 with built-in SBUS inverter, UART6 dedicated to Wireless Board telemetry. Enough ports for GPS, VTX, receiver, and telemetry simultaneously. ✅ High-Capacity PDB with Triple BEC — 2–6S LiPo input (7–36V), 90A continuous / 215A peak current sensor, 5.2V FC BEC, 9V VTX BEC (adjustable to 12V or 5V), and 4.9V servo BEC (adjustable to 6V or 7.2V). TVS protective diode included. ✅ MicroSD Blackbox — Onboard MicroSD card slot for full INAV blackbox logging. Analyze flight data post-flight for tuning and troubleshooting. ✅ ICM-42688-P Gyro + SPL06 Barometer — High-performance IMU with barometer for accurate altitude hold and navigation in fixed-wing and VTOL flight modes. ↑ Back to Contents Compatibility Conventional fixed-wing aircraft (standard aileron/elevator/rudder) V-tail aircraft Aircraft with flaperons VTOL platforms (supported via INAV) ELRS / CRSF receivers (UART1) and SBUS receivers (UART2-RX) HD and Analog VTX (plug-and-play interface) WS2812 LED strips (4 channels, up to 70 pcs 5050 beads) ⚠️ Important: Always verify servo BEC voltage jumper setting (4.9V / 6V / 7.2V) before connecting servos. VTX BEC defaults to 9V — adjust via jumper if your VTX requires 5V or 12V.
