  • Crafted for advanced pilots, the ultra-thin (0.8mm) and lightweight Air FC is engineered for maximum agility and race-winning performance. It is the definitive choice for pushing the boundaries of FPV flight.  For newcomers to FPV or those flying for entertainment, the Matrix FC is the ideal alternative. It offers enhanced durability, requires no welding, and provides a more beginner-friendly experience.
  • VTX Power: Higher VTX power consumes more energy and generates more heat, reducing flight time. For better flight time in indoor scenarios, use 25~100mW power. 
  • The calibrated power measured after temperature stabilization (stabilization condition: more than 60 seconds after powering on the flight controller) is: when set to 25mW, the output power is between 14dBm±0.8dBm (21mW to 30mW), which meets the normal standard. The following is the 5IN1 Air FC test data with the VTX set to 25mW, the power data is tested at different times on the R1, R3, R5, and R7 frequency points.
  • Motor Wiring: Only soldering is supported for motor wiring on the flight control. Be careful to ensure the temperature of the soldering iron is maintained below 370℃ and limit the soldering duration to 1~2 seconds.

 

Bullet Points

  • Air Brushless Flight Controller, the first 1S FC that utilizes the G473 processor, experienced a remarkable 55% increase in computing speed and lightning-fast response times for precise racing and complex freestyle maneuvers, surpassing the F411.
  • Higher integration yet lightweighter design, featuring a custom miniature OSD chip. Weighing only 2.9g (4IN1 Version) or 3.6g (5IN1 Version), it offers extra UART port options for effortless function expansions, adapting flawlessly to any flight scenario.
  • Default integrated onboard 25-400mW VTX. Streamlines installation saves space, reduces weight, and boosts convenience for VTX and FC adjustments. The 5IN1 Version even integrates the Serial ELRS 2.4G RX.
  • Elevate your drone's precision with the industry-leading ICM42688P gyro, integrated accelerometer, cutting-edge sensor calibration, and filtering algorithms, and a sample rate of up to 8K, which takes the drone's posture and movement accurate and precise drone to the next level.
  • Unlock extensive flight data recording and analysis with an impressive up to 16MB capacity black box. Maximize performance and diagnose faults effectively, leveraging the full potential of your drone.

Comparison Between G473 and F411

Say goodbye to limitations and embrace the cutting-edge technology of the G473 flight controller for an unparalleled flight experience. Air Brushless Flight Controller features up to 168MHz superior CPU Clock Speed and 4 richer serial ports, enabling lightning-fast response times and advanced computing power, making it ideal for demanding flight, which takes your flying experience to the next level and demonstrates outstanding performance, surpassing all 1S FC options available on the market at present. 

 

Betaflight Firmware and CLI 

Betaflight official developers recommend using version 42688 of the gyroscope, and many issues with ICM42688 have been fixed in version 4.5.0. Please learn more from version 4.5.0.

Bluejay ESC Firmware

With BB51 ESC solution,  Air Brushless Flight Controller is based on A_X_5_96KHz_V0.19.hex for BB51 Bluejay hardware, it supports D-shot300, D-shot600, and even RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies. 

DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.

 

Connecting External RX/VTX

Please note that UART2 has connected to the VTX by default. This FC reserves 3 complete full-featured serial ports that can be used for external CRSF/SBUS receivers, GPS, HD VTX, or other serial devices. You can refer to the below pictures. 

Attention

  • VTX Power: Higher VTX power consumes more energy and generates more heat, reducing flight time. For better flight time in indoor scenarios, use 25~100mW power.
  • Motor Wiring: Only soldering is supported for motor wiring on the flight control. Avoid terminal plugging.
  • VTX Antenna: Connect and install the image transmission antenna before powering on the flight control. Alternatively, set transmission power to 0 to avoid burnout.

Lovely Slate Gray Jewelry Box
I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.

Songmics Slate Gray Travel Jewelry Box
I purchased the slate gray Songmics jewelry box for travel purposes. We take long vacations and have an upcoming 20 day cruise. I wanted a jewelry box that was compact enough to put in my carry-on bag, but still had room to hold a months worth of jewelry, especially to keep my necklaces for tangling. When this arrived, I was pleasantly surprised and the packaging was great, shipped in a sturdy box. so no damage to the jewelry box. The color is a rich gray and the 2 tier box, while small, holds a lot of jewelry. I wanted to purchase the ink black but could not justify paying twice the price of the gray one just to get it in black. It is small enough that it will fit in most any hotel/ship safe so I won't be sitting out in the room anyway. It has a strong magnetic snap that keeps the box from opening while in transit. The one negative for me is that the pierced earring card is so thick that my earrings barely go through to have enough room on the back side the slip the backs on. I may separate the double thick card, realizing it will not look as nice but will be more functional. The bottom half of the box will hold bracelets up to 1 1/4" wide. There is enough room under the earrings card to place pendants, additional earrings, etc. The necklace holder is designed to hold 5 necklaces, but I added one more by going across the top, end to end, to prevent tangling. I also placed smaller hoop earrings in the ring holder which holds them securely. This box held 7 bracelets, 2 of which were wide, 5 rings, 9 necklaces (I placed 3 in the bottom of the box, and had room for 23 pair of earrings (some placed in the ring holder and in the bottom of the bo)! I would buy this again in a heartbeat.
