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 Traditional betaflight OSD's use a functional, but outdated OSD with limited features and update rates.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 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 Traditional betaflight OSD's use a functional, but outdated OSD with limited features and update rates.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:

Key Features

  • Best setup manual ever made
  • Improved form factor for easier soldering of PDB / 4-in-1 ESC underneath RADIX FC
  • Plug-and-play stacking on RADIX PB or Hobbywing 4-in-1 ESC using soft cables for vibration isolation
  • Graphical OSD - the only flight controller running BF with this feature
  • Customizable OSD logos using the BrainFPV Logo Customizer
  • STM32 F4 processor running at 180MHz
  • Better sensors - Bosch BMI160 gyro, proven on RE1 (pilots are raving about it)
  • Integrated barometer - so you always know how high you are
  • MicroSD card slot for logging
  • Integrated silicone grommets for vibration isolation
  • Dedicated camera control pad for changing camera settings
  • Dedicated RGB LED output for programmable LEDs
  • Four full hardware serial ports (UARTs) - two of them have signal inverters that are automatically enabled or disabled, so they can be used with S.Bus or SmartPort
  • 6 motor outputs with support for DSHOT (150/300/600/1200) and OneShot
  • Supports Betaflight
  • Engineered and tested in the USA

Almost perfect, absolutely fit for purpose, and a great value
Size: Standard--black
These are really, really close to being five stars, but because of my OCD tendencies when it comes to things being true and level, I can only go four. The way these mounts are made, speakers rest inside and on the inner surface of the L-shaped adjustable side brackets, and not on the large metal plate between them. Leveling on the fore-and-aft plane can easily be handled via the adjustment nut on the bottom of the bracket. But there is no provision for side-to-side leveling, so if the manufacturing of the side brackets is not within tolerance, you'll wind up with a speaker that's ever-so-slightly wonky...which is the case with ONE of my mounts. The bubble is still between the lines, but it's kissing the left line. Most would not care about this, and I'm not too bummed about it, but I am able to see that much out-of-true with the naked eye. It's not enough to pursue any kind of remediation, because the value on these really is awfully good. They are solidly built, easy to install, and easy to adjust. The manufacturer is apparently improving the product as they go based on feedback, as some issues that have vexed other owners have not been a problem for me, such as the wall plates being or coming loose (the design now ensures they stay put once pushed back to the wall), or the adjustment nut and bolt rotating freely and not staying tight (the ones on mine are great and function as intended). For the price, these are really hard to beat, and I have a feeling all the mounts like this with the different oddly-named brands are made in the same factory. That being the case, get the cheapest ones, and the day I bought mine, these were those.

Solid and easy to install
Size: Standard--black
These are nice, solid wall mounts. They assembled quickly and easily, and they can hold larger bookshelf speakers like my Cambridge Soundworks M60s. Adjusting the plate to match speaker size is pretty easy, and they seem to grip the speaker tight enough that they won't fall off. The tilt option is very useful and a good feature when speakers are mounted high and need to tilt down toward the listener. Just remember to tighten the bolt on the bottom once you've positioned it where you want it. I would definitely recommend these to anyone looking for solid, well priced speaker mounts.

Sturdy solution
Size: Standard--black
I needed a way to mount rear speakers and this was the solution. They're sturdy and adjustable to fit reasonably sized speakers. They also pivot up and down and swivel so really perfect.
