BrainFPV Radix Flight ControllerThe BrainFPV Radix represents a step forward when it comes to betaflight flight controllers. The two main features are a robust Bosh Gyro, and a fancy modern OSD chip. Traditional betaflight OSD's use a functional, but outdated OSD with limited features and update rates. The team at BrainFPV wanted something better so insead uss a graphical OSD chip that enables alot more features, and it just looks nicer. The Bosh Gyro also mean that this FC performs

The BrainFPV Radix represents a step forward when it comes to betaflight flight controllers. The two main features are a robust Bosh Gyro, and a fancy modern OSD chip. Traditional betaflight OSD's use a functional, but outdated OSD with limited features and update rates. The team at BrainFPV wanted something better so insead uss a graphical OSD chip that enables alot more features, and it just looks nicer.

The Bosh Gyro also mean that this FC performs great in the air. Other than that it has all the other features you expect and need from a betaflight FC.

Please make sure to read the quickstart guide before using this flight controller, as the firmware flashing is slightly different:

Good quality and value!
Size: 12 Packs, Style: Lunch Napkin
Less expensive than the same amount of napkins at our local BJ’s. Bought my first box for my son’s grad party (a few years ago) and I’ve been buying napkins this way ever since.

Good Napkins for Parties and Everyday Use
Size: 12 Packs, Style: Lunch Napkin
These AmazonCommercial 1‑ply lunch napkins were a good purchase. They’re lightweight but still hold up well for quick meals, snacks, and parties. The pack comes with plenty of napkins, which makes them great for events or keeping on hand at home. They’re not super thick, but for casual use they get the job done without falling apart. The white color looks clean and works for any occasion. Overall, they’re a simple, affordable option that’s reliable for restaurants, parties, or everyday family use.
