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. itís not just an FC. Itís also a PDB
  • This FC is designed for the micro femtoquad. Itís 20mm by 20mm and has no mounting holes
  • Thus youíll have to mount it using double sided tape
  • Which honestly is a good thing because thatís 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 itís size
  • Itís 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 donít 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

EMAX Femto Flight Controller
Iíve gone through 3 of these in the past month, these flight controllers have nothing but issues. Two of mine had issues where they wouldnít 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 wasnít working I found that it wasnít the motor or ESC. Another one I had wouldnít power up no LED lights through USB.
