Buying Guide: iFlight BLITZ Whoop F7 55A AIO
A powerful AIO flight controller can simplify an FPV build by combining the flight controller and 4-in-1 ESC into a single board. This is especially useful for compact Cinewhoops and lightweight performance builds where space, wiring, and overall weight matter.
The iFlight BLITZ Whoop F7 55A AIO combines a STM32F745 processor, ICM42688 gyro, 16MB Blackbox storage, and a 55A 4-in-1 ESC in a compact 25.5 × 25.5mm AIO format. With support for 2-6S LiHV batteries, it is designed for powerful compact FPV builds that need strong ESC performance without using a separate FC and ESC stack.
Who Is the BLITZ Whoop F7 55A AIO Best For?
Despite the "Whoop" name, this is a high-power AIO rather than a typical low-current Tinywhoop board. The 55A ESC makes it more suitable for compact but demanding FPV builds.
It is particularly suitable for:
● 2.5-3.5 inch Cinewhoop builds
● Lightweight 3-5 inch FPV builds
● Compact 2-6S performance drones
● Pilots who want fewer wires and a lighter electronics setup
● Builds requiring an F7 processor and strong ESC headroom
Why Choose an F745 Flight Controller?
The BLITZ Whoop F7 uses a STM32F745 processor running at 216MHz. An F7 processor provides strong processing capability for modern Betaflight configurations and can support more advanced features than many entry-level FC platforms.
This makes the board suitable for pilots who want to use modern flight features while keeping the electronics layout compact. The board also includes 16MB onboard Blackbox storage for flight logging and tuning analysis.
2-6S Battery Compatibility
One advantage of the BLITZ Whoop F7 AIO is its wide 2-6S input range. This gives builders flexibility when choosing between lightweight lower-voltage setups and higher-power 6S configurations.
The correct battery choice depends on the motors and intended aircraft. Smaller Cinewhoops may use lower-voltage batteries, while larger and more powerful builds may benefit from 4S or 6S systems. Always match battery voltage to the motor KV and other onboard electronics.
ICM42688 Gyro and Barometer
The flight controller uses an ICM42688 gyro for flight stabilization and includes a DPS310 barometer. These sensors provide the flight controller with motion and altitude-related data for supported flight functions.
For most pilots, the gyro is the more important component for everyday flight performance. The onboard barometer can also be useful for builds using supported altitude-related functions.
Why Choose an AIO Instead of a Full Stack?
An AIO board combines the flight controller and ESC into one unit. This reduces the number of components, shortens wiring, and can save weight compared with a traditional FC and 4-in-1 ESC stack.
For compact frames with limited internal space, this can significantly simplify installation. The trade-off is that the FC and ESC share one board, so replacement options may be less flexible than with separate components.
iFlight BLITZ Whoop F7 55A vs Aikon F7 60A AIO
The Aikon F7 60A AIO is one of the closest alternatives because both boards combine an F7 flight controller and high-current 4-in-1 ESC in a 25.5 × 25.5mm AIO format. The main differences are processor type, battery range, ESC capacity, weight, and onboard features.

| Best For | Lightweight Cinewhoop and compact high-performance builds | High-current compact builds requiring stronger ESC capacity |
Which One Should You Choose?
Choose the BLITZ Whoop F7 55A if: you want the lighter board, need 2S compatibility, prefer the F745 processor and ICM42688 gyro, or are building a compact Cinewhoop where minimizing electronics weight matters.
Choose the Aikon F7 60A if: you need slightly higher ESC current capacity, a dedicated 10V BEC for compatible DJI HD systems, or additional connectivity for a more demanding compact build.
Before Installing the BLITZ Whoop F7 AIO
Before purchasing, confirm that your frame supports a 25.5 × 25.5mm mounting pattern. Also check motor current requirements, battery voltage, VTX power requirements, and available installation space.
Because this is an AIO board, the entire power system is integrated into one PCB. Use a smoke stopper during the first power-up and always remove propellers while configuring motors in Betaflight
