The EMAX Femto Flight Controller is a perfect choice for the micro builds where every millimeter of space is crucial! Boasting a 20x20mm size, the Femto is extremely flexible with the quads it can be utilized for within the micro world.

  • The size is tiny. it’s not just an FC. It’s also a PDB
  • This FC is designed for the micro femtoquad. It’s 20mm by 20mm and has no mounting holes
  • Thus you’ll have to mount it using double sided tape
  • Which honestly is a good thing because that’s an effective method of soft mounting a FC anyway
  • The FC even has an LC filtered 5v regulator for your camera and VTx which is outstanding given it’s size
  • It’s also got LED and buzzer pads, VBat, and is capable of using 2-4s LiPo batteries
  • This FC should be perfect for those sub 150mm sized micro quads (which don’t produce much noise to begin with)
  • Size: 20mm*20mm
  • Weight: 2.2g
  • Buzzer support
  • STM32F303 CPU
  • 2-6S LiPo battery
  • Integrated 5V/3A BEC
  • 2.0 mm pin headers
  • 80A Current tolerance (PDB)
  • Integrated Battery monitoring
  • Dedicated PPM receiver input
  • BLHeli Passthrough Support
  • Supports direct connection of 3.3v Spektrum Satellite receivers
  • Telemetry support (frsky telemetry, smartport, and HoTT telemetry)
  • MPU9250 accelerometer/gyro/compass (connected via SPI)
  • Dedicated Sbus and serial RX with 5v ,Spektrum 1024/2048, SBUS, XBUS, SumD and SumH RX with built-in inverter
  • Dedicated output for programmable LEDs - great for orientation, racing and night flying. (Currently mutually exclusive with the Transponder)
  • Use all the features all the time; e.g. Connect your USB + SmartPort + SBus + LED Strip + Battery Monitoring + 4 motors - all at the same time!
  • UART3 (RX3)
  • Use for Spektrum Satellite RX, Spektrum 1024/2048, SBUS, XBUS, SumD and SumH RX, etc.
  • UART2/PPM - Serial RX or PPM RX + Telemetry
  • Use RX2 as PPM receiver. Use TX2 as telemetry output when using PPM

EMAX Femto Flight Controller
I’ve gone through 3 of these in the past month, these flight controllers have nothing but issues. Two of mine had issues where they wouldn’t spin up 1 out of the 4 motors no matter what I did, one was motor number 3 the most recent one was motor 2. After doing testing by swapping ESCs and motors to the side that wasn’t working I found that it wasn’t the motor or ESC. Another one I had wouldn’t power up no LED lights through USB.
