BotStack BotWing F405 Stack | 55A AM32 ESC | Betaflight INAV ArduPilot | The FPV Project

The BotStack BotWing F405 is a solderless flight controller and ESC combo stack from Botlab Dynamics — India’s own FPV hardware brand. It pairs an STM32F405 flight controller with a 32-bit 55A AM32 4-in-1 ESC on a compact 30.5×30.5mm stack, designed to make FPV builds cleaner, faster, and more beginner-friendly without sacrificing performance or firmware flexibility.

Why choose the BotStack BotWing F405?

Most stacks at this price point force you to choose between firmware compatibility and build simplicity. The BotWing F405 gives you both — a solderless plug-and-play design that avoids common wiring mistakes, combined with full support for Betaflight, INAV, and ArduPilot / Mission Planner. Whether you’re building a freestyle quad, a GPS long-range cruiser, or an autonomous platform, this stack handles it from one board combination. Pair it with components from our flight controller and AIO range for a complete build.

Key features

Solderless design — clean builds, fast assembly

The BotWing F405’s solderless connector system eliminates the need to solder the FC-to-ESC connection, reducing build time and removing one of the most common sources of wiring errors in FPV assembly. All main connections use secure plug-in connectors.

ICM42688P gyro with 32MB blackbox

The high-precision ICM42688P gyro delivers low-noise, vibration-resistant flight data — the same sensor used in premium-tier flight controllers. Combined with 32MB of onboard blackbox storage, you get detailed flight logs for PID tuning and troubleshooting without needing an SD card.

AM32 32-bit ESC — smooth, tuneable motor control

The BotDrive ESC runs AM32 firmware on an AT32F421 MCU — a 32-bit architecture that delivers smoother throttle response, better telemetry, and easier firmware updates compared to 8-bit ESC alternatives. Supports DSHOT300/600 and PWM protocols with bidirectional DShot telemetry.

55A continuous / 60A burst per motor

With 55A continuous and 60A burst per channel on 2-6S LiPo, the BotDrive ESC handles power-hungry 5-inch freestyle motors and heavier builds without throttling or overheating.

Betaflight, INAV and ArduPilot compatible

Full compatibility with Betaflight for freestyle and racing, INAV for GPS navigation, and ArduPilot / Mission Planner for autonomous builds — all from the same hardware stack. Update firmware via Mission Planner, INAV Configurator, or Betaflight Configurator.

DJI Air Unit plug-and-play

Direct DJI Air Unit plug-in support via dedicated connector — no rewiring or adapters required for DJI digital HD builds.
