Airbot FCs Video Wiring

I’m sure this tip will be useful for some of you out there who use Airbot’s fantastic flight controllers like the OMNIBUS F3 AIO Pro or OMNIBUS F4 AIO and have some trouble with flickering or disappearing OSD.

To get clean video without noise you actually have three options (to power the camera).

  1. Get clean power from a PDB with some kind of filtering.
  2. Get clean power from OMNIBUS FC.
  3. Get clean power from your VTX (video transmitter).

My choice was to get the 5V for the camera from my VTX because it delivered very clean power and the video was perfectly clear on my previous builds with Foxeer TM25 (40CH 5.8G 25/200/600mW Switchable VTX). However I had the problem that my OSD from OMNIBUS F3 Pro was flickering when applying throttle. It turned out that the ground circuit is not closed properly. After fixing that I had extremely clean video and no OSD issues at all (see wiring picture).

Please note that this is not a workaround for something that is broken on the FC. It’s just a fix for something I messed up.

8kHz/8kHz 4″ ImpulseRC Alien

Shout out to Airbot for providing the OMNIBUS F4 for this “alien on steroids” build.

Featuring EMAX red bottoms 2600KV and Racerstar 30A V2 BLHeli_S ESCs.

ImpulseRC Helix Build In Progress

Racerstar 30A ESCs fit perfectly fine inside the fairings. I can’t wait to test the super cheap Racerstar motors.

The Beauty Of A Kissed 5″ Alien

I should probably fly more and stop building…

Martian 220 Rebuild

I like the frame so much that I designed a GoPro session mount for it. Take the STL file from Thingiverse. This is my best and cleanest build until now. The Matek PDB with XT60 connector on the board and linear regulator on the 12V pad for clean video are super cool.

Martian Ready To Fly

PDB replacement was necessary due to horrible video noise and PDB burning (probably caused by screws contacting the boards electronics).

Diatone ZMR 200 Build

Diatone ZMR 200 is ready to fly.

The power distribution board is a complete fail, don’t buy it. It burns out or if you are lucky you get horrible video noise and the OSD vanishes when applying throttle. There is a fix for this: soldering external capacitors. However I don’t feel like fixing complete boards like this with huge capacitors which make the build look like crap. This quadcopter needs a rebuild with new PDB and maybe even a cheap FC with OSD.
