Nearer Take a look at the GOKU F722 Professional V2
From the specs, the GOKU F722 Professional V2 provides all the fashionable options you’d need on a flight controller.
Aesthetically, it’s interesting with its white PCB. It options JST connectors on the highest of the board and solder pads on the underside, providing a flexible resolution for various construct preferences.
Nevertheless, inserting the solder pads on the underside makes it tougher to work with for many who choose soldering. Until you often want to exchange elements within the discipline, JST connectors won’t supply important advantages over direct soldering.
The board features a barometer, helpful for INAV firmware, and 16MB of reminiscence for Blackbox recording, which is helpful for tuning.
Is F7 Higher Than F4?
In brief, it actually doesn’t matter which processor you utilize, the distinction between F722 and F405 doesn’t considerably impression flight efficiency for many pilots at present. F722 provides extra processing energy, supporting increased speeds like 8K PID loop and DShot600 whereas F405 solely helps 4K PID Loop and DShot300. Nevertheless, the sensible advantages in flight of the sooner PID loop are minimal.
The F405’s bigger reminiscence (1MB) truly would possibly make it extra future-proof than the F722 (512KB) as firmware sizes develop, regardless of being a slower processor. Observe that Betaflight’s new cloud construct system helps handle firmware measurement, extending the lifespan of processors with smaller reminiscence, so F722 will nonetheless be supported within the foreseeable future.

How Does Flywoo Evaluate to Speedybee?
Whereas the Flywoo GOKU F722 Professional V2 and Speedybee F405 V4 stacks are comparable in capabilities, the Speedybee stack is $14 cheaper and provides a extra strong ESC on paper, with increased present rankings. The Speedybee stack undoubtedly provides higher worth.
Nevertheless, the Flywoo stack has its benefits:
- The MPU6000 Gyro is most popular by many for its clear efficiency and ease of tuning.
- JST connectors scale back the necessity for soldering, simplifying peripheral connections.
- Onboard reminiscence for Blackbox logging is handy, whereas on the Speedybee you’ll want a micro SD card.
- F7 FCs simplify sign inversion for Frsky receivers, though that is much less related for ExpressLRS customers.
You should buy the Flywoo GOKU F722 Professional V2 Stack from:
The Mini 20x20mm Stack:
Full Dimension or Mini Stack?
The GOKU F722 PRO Mini V2 Stack, with its 45A ESC, is appropriate for many freestyle 5″ FPV drones. It’s $4 cheaper, smaller, and lighter than the full-size stack. Moreover, it makes use of a 32-bit ESC operating AM32 firmware, which provides increased PWM frequency choice as much as 128KHz, though this isn’t significantly related for five″ drones that usually use 24KHz or 48KHz.
One other consideration is the gyro: the full-size FC makes use of the MPU6000, whereas the Mini FC makes use of the ICM42688-P.
Nevertheless, the full-size stack offers extra actual property, making it simpler to work with for soldering and repairs. Moreover, the ESC has bigger FETs and higher warmth dissipation, each are indicators of a extra dependable ESC. In case you are constructing a strong drone, the full-size stack could be the higher alternative.
Conclusion
I’m happy to see the market providing extra budget-friendly FC stacks with numerous options. The Flywoo GOKU F722 Professional V2 Stack is an interesting possibility, offering strong capabilities and considerate design with prime notch construct high quality. I hope this assessment helped you select between the total measurement and mini variations, and the Speedybee F405 V4 stacks.
