The BeeBrain BLV3 Flight Controller Flight Controller!

The latest iteration of the BeeBrainBL contains massive improvements to the performance of the built in FrSky Receiver and built in video transmitter.

In addition, the MOSFETs were upgraded to support the power demands of micro toothpick drones.

The solder pads on each ESC were enlarged to enable custom builds! With plenty of surface area and spacing, you can now solder on any motor of your choosing. One of our favorite applications of the BeeBrain BL is in micro drones. Since the BeeBrain BL integrates the flight controller, ESCs, receiver, and video transmitter all in one package, it's insanely easy and clean to build.

Receiver Improvements - 50% More Range

  1. Optimized SPI Receiver hardware to improve efficiency within the receiver.
  2. Removable antennas.
  3. Additional low noise amplifier to increase range.
  4. Optional wiring harness is included to install an external receiver (Crossfire, Ghost, etc)

Video Transmitter Improvements - 120mW

  1. New heatsink and layout to increase heat dispersion and efficiency.
  2. Transmitting power increased to 120mW from 25mW (V2)

Problematic flight controller

I have the Savagebee. Out of the box it flew great, but shortly after it failed without any crash. Motor 2 stopped working, board issue. I sent it back to NewBeeDrone and paid for a replacement flight controller. The new flight controller lasted about 2 minutes before it failed. Motor 4 lost all control and is not longer functioning. Not a motor issue, but the board. Still waiting to hear back from their support again.

I have bought the Crux35 in the meantime and have enjoyed flying it without any problems!

Larger motor pads

Great AIO for with plenty of power for 65-75mm whoops. The larger motor pads are a welcome upgrade.

Simply the best.

Super easy to use everything about this fc works great. I ran tracer with mine and everything about the setup process was pretty easy. Love this fc.

Newbeedrone delivers again.

Great feature set, poor execution?

I bought this because it is has great features on paper, but I warrantied one due to ESC burning out and then the second one also had a mosfet burn out. Really wanted this to work out. Not sure if its my fault or just doesnt live up to the 12A rating. I should only have been pulling 6A so seems like 12A isnt realistic? When it worked it was great.
