Design and Options

Proper off the bat, the dimensions of the Speedybee F405 Wing MINI is its most hanging characteristic. This compact flight controller is considerably smaller than its sibling, the usual F405 Wing FC. Its small kind issue is a big benefit for builds the place house is at a premium.

Regardless of its smaller dimension, it brings a number of notable options to the desk. The power to change between C1 and C2 cameras is a recent addition not generally seen on F405 boards, enhancing versatility for pilots who make the most of a number of digital camera setups.

One of many standout options is its wi-fi tuning functionality, proved to be helpful in establishing and making parameter changes with out the effort of plugging within the USB cable.

The inclusion of SBUS enter pins and uncovered pins for UART1, permitting for compatibility with varied radio programs like Frsky, ExpressLRS and Crossfire, is a considerate contact.

With 11 PWM outputs, six UARTs (one reserved for WiFi), and assist for each digital and analog video transmitters, the F405 Wing Mini is designed to cater to a variety of flying types and preferences.

The package consists of each right-angle and vertical header pin choices for connecting servos and receiver, enhancing the flexibleness in mounting based mostly on the out there house inside your construct. The board additionally helps twin cameras and digital FPV programs, catering to a variety of consumer preferences.

Set up and Setup

The Speedybee F405 Wing Mini comes with every little thing wanted for meeting, avoiding the frequent frustration of trying to find appropriate cables or connectors. The considerate inclusion of a capacitor and completely different boards for backside mounting choices speaks to Speedybee’s dedication to consumer comfort.

One factor to notice is the orientation of the facility distribution board, which is designed to sit down on the high.

Organising the FC was a breeze, thanks partially to the detailed guide and the SpeedyBee app’s intuitive interface. Whereas wi-fi firmware flashing is just not supported by the SpeedyBee app but, it does assist INAV 7 from the get-go which is a significant plus. You may also flash firmware and configure the FC the normal manner utilizing your PC by way of USB cable.

The F405 Wing Mini’s small dimension didn’t compromise its functionality to ship a secure and responsive flight expertise. The board’s design facilitates straightforward wiring and element attachment, though the bizarre mounting gap sample could require some adaptation, resembling utilizing double-sided foam tape for set up.

Closing Ideas

The Speedybee F405 Wing Mini flight controller stands out for its compact dimension, complete characteristic set, and ease of use. Its design caters to each novice and skilled customers, offering every little thing wanted for a profitable construct proper out of the field. That’s why in addition they name this FC “Simple Fly” which makes loads of sense.

You may get the SpeedyBee F405 Wing Mini FC stack from these distributors:

For these seeking to experiment with iNav or searching for a dependable, space-saving resolution for his or her RC plane, the F405 Wing Mini is a compelling possibility. Speedybee continues to impress with their improvements within the RC flight controller market, and I’m desirous to see how this mini controller will likely be obtained by the neighborhood.
