Assessment: Flywoo GOKU F722 Professional V2 FC/ESC Stack – 30.5×30.5mm and 20x20mm Mini Flight Controller

On this submit, I’ll share my ideas on the Flywoo GOKU F722 Professional V2 flight controller stack, out there in each full dimension (30.5×30.5mm) and mini (20x20mm) variations. These stacks differ not solely in mounting patterns but in addition in ESC kind. Let’s dive into these new stacks and see how they evaluate to opponents just like the Speedybee and GEPRC Taker finances stacks.

The place to Purchase?

You should purchase the Flywoo GOKU F722 Professional V2 Stack from:

The Mini 20x20mm Stack:

Each stacks include a complete package deal, together with a number of pin cables with JST connections, rubber spacers, and O-rings, making them prepared for varied setups.

Specs

Listed here are the detailed specs for each the GOKU F722 Professional V2 stacks (30.5×30.5mm full dimension and 20x20mm mini).

Variations Between Speedybee and Flywoo

Right here’s a comparability desk between the GOKU F722 Professional V2 (full dimension) and Speedybee F405 V4 stacks.

Nearer Take a look at the GOKU F722 Professional V2

From the specs, the GOKU F722 Professional V2 affords 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 answer for various construct preferences.

Nonetheless, inserting the solder pads on the underside makes it tougher to work with for many who want soldering. Until you regularly want to interchange parts within the subject, JST connectors won’t provide important advantages over direct soldering.

The board features a barometer, helpful for INAV firmware, and 16MB of reminiscence for Blackbox recording, which is useful 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 affect flight efficiency for many pilots at the moment. F722 affords extra processing energy, supporting larger speeds like 8K PID loop and DShot600 whereas F405 solely helps 4K PID Loop and DShot300. Nonetheless, the sensible advantages in flight of the sooner PID loop are minimal.

The F405’s bigger reminiscence (1MB) really 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 dimension, 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 related in capabilities, the Speedybee stack is $14 cheaper and affords a extra sturdy ESC on paper, with larger present rankings. The Speedybee stack undoubtedly affords higher worth.

Nonetheless, the Flywoo stack has its benefits:

• The MPU6000 Gyro is most well-liked 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.

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 working AM32 firmware, which affords larger PWM frequency choice as much as 128KHz, though this isn’t significantly related for five″ drones that sometimes 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.

Nonetheless, 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. If you’re constructing a robust drone, the full-size stack is likely to 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 choice, offering sturdy capabilities and considerate design with prime notch construct high quality. I hope this evaluate helped you select between the total dimension and mini variations, and the Speedybee F405 V4 stacks.
