CoreWing F405 WING V2 vs SpeedyBee F405 WING APP

Last Updated: October 2026 | Difficulty: Beginner–Intermediate | Author: Dannyi Chen

Dannyi Chen, RC enthusiast and technical writer at SoarSky. This comparison evaluates documented specifications and setup requirements, not measured flight-test results.

Is the SpeedyBee F405 WING APP discontinued?

This review does not establish an official discontinuation announcement. Retailer shortages, forum discussions or a missing product page alone do not prove end-of-life status or the absence of warranty coverage. SoarSky currently lists its SpeedyBee variant as available for sale; that is not evidence of global stock or future restocking.

For a working SpeedyBee installation, keep flying it if its power budget, firmware and peripherals meet your requirements. A new board is not automatically a reason to replace a reliable setup.

How do the CoreWing and SpeedyBee designs compare?

Both use an STM32F405 processor, a stacked fixed-wing layout, integrated power distribution and wireless connectivity. Similar architecture does not establish corporate lineage, identical firmware targets or electrical interchangeability.

CoreWing offers BMI270 and ICM-42688-P variants, each with unsoldered or straight-pin-soldered options. Select by installation needs rather than an unsupported claim that one IMU guarantees better flight performance.

Which specifications matter for your aircraft?

Input voltage, servo current demand and output protocol are the most important fit checks. The following figures refer to the full-size WING boards, not WING MINI models.

What changes in everyday setup?

CoreWing provides higher published power ratings and a different peripheral map, while wireless convenience depends on the app and firmware used.

Servo and peripheral power

CoreWing's 8A continuous servo rating gives more rated headroom than SpeedyBee's 4.5A. It does not eliminate brownouts: servo stall demand, wiring resistance, battery condition and cooling still matter. Do not parallel an ESC BEC with the servo rail unless the documented jumper configuration allows it.

VTX switching and bench safety

CoreWing supports switchable VTX power, and supported SpeedyBee revisions do too. ArduPilot documents GPIO 81 for both; confirm your board revision and installed firmware before setting a relay. Provide cooling whenever the VTX is powered, remove propellers during setup and verify video power before launch.

Wireless setup and firmware

ArduPilot documents CoreWing BLE, Wi-Fi AP/STA, app parameter setup and wireless flashing, plus Mission Planner Wi-Fi connections. CoreWing's official setup page requires wireless-board firmware 8.1.0 or later for the CoreWing app. Follow the current CoreWing manual and upgrade tutorial; app compatibility is not a promise that every feature works in every firmware.

UART mapping

CoreWing's default ArduPilot map uses USART1 for wireless, USART6 for serial RC, UART5 for GPS and USART3 for the HD/VTX connector. SpeedyBee's default map differs. DMA capability and protocol settings must be checked per UART; do not infer guaranteed link reliability from the diagram alone.

Which CoreWing version should you choose?

Choose the header arrangement that fits your build first, then the IMU option that your intended firmware supports. Current SoarSky variants are listed below.

The matching ICM42688 option costs $10 more. This review does not contain comparative flight testing that establishes better vibration tolerance or identical flight performance. Confirm supplied headers and physical clearance on the product page before ordering.

How should SpeedyBee owners migrate safely?

Treat CoreWing as a fresh installation, not a plug-in board swap. The supplied comparison chart warns that the PDB power pin order differs.

1. Back up the old configuration and photograph wiring before removing anything.
2. Install the correct firmware for the exact board. ArduPilot identifies the full-size target as CoreWingF405WingV2. Check the current INAV release and manufacturer downloads rather than relying on an unverified minimum-version claim.
3. Rewire peripherals to the new board's documented UARTs. Select protocols and baud rates explicitly.
4. Set servo and VTX voltage to match the connected equipment. Recalibrate sensors and validate battery measurements; do not blindly copy calibration values or a complete parameter file.
5. With propellers removed, verify receiver inputs, servo direction, output assignment, failsafe, power behavior and any VTX relay. Complete a controlled first-flight check.

Both F405 platforms have ArduPilot flash-memory limitations. Check that the selected build includes the sensors and features your aircraft requires.

SoarSky Editorial Experience: which board would we choose?

Our editorial recommendation is CoreWing for a new compatible 3–6S build that benefits from its higher-rated power rails; keep a functioning SpeedyBee when it already fits the aircraft. This is a documentation-based assessment, not a buyer review or a claim of hands-on comparative testing.

For 2S aircraft, the full-size CoreWing V2 is outside its documented input range. For multi-motor installations, check DShot timer groups and CoreWing's PWM-only S11/S12. For an existing SpeedyBee build, confirm revision-specific VTX switching before replacing hardware to obtain that feature.

What are the common compatibility questions?

Is CoreWing V2 a drop-in SpeedyBee replacement?

No. Similar architecture does not mean interchangeable pinouts, modules or firmware. Treat migration as a new installation.

Can I mix their PDB or wireless boards?

Do not mix modules based on connector fit. Use matched assemblies and verify the current manual's pinouts before powering up.

Can CoreWing F405 WING V2 run on 2S?

No. The full-size WING V2 is specified for 3–6S and 10–28V input; do not confuse it with WING MINI models.

Does SpeedyBee support VTX power switching?

Supported revisions do. ArduPilot documents GPIO 81 switching and notes that early board revisions lack the feature.

Which CoreWing IMU option should I buy?

Choose by firmware support, header layout and budget. This review does not establish a measured flight-performance advantage.

Can CoreWing flash firmware wirelessly?

Its app supports wireless flashing with the wireless board configured. Follow the current manual and use the exact board target.

FPV Flight Controller Complete Guide
Review processor, firmware and peripheral selection fundamentals before comparing boards, while checking every wiring decision against the exact fixed-wing manual.

FPV Drone Frame Guide
Explore multirotor frame size and layout considerations if your wider project includes drones; it is not a fixed-wing airframe selection guide.

Understanding FPV Motor Specifications
Learn motor specification terminology before planning a powertrain, then check aircraft-specific propeller, ESC and current requirements using appropriate manufacturer data.
