This is a simple base to mount an EMAX Femto F3 Flight controller PDB to 20x20mm FC hole spacing on a micro FPV frame.

Features

• 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).
