Hey all, another new to FPVer here! Been flying RC planes for 15 years and want to try something new. I’ve bought DJI googles, motionsic BAG and head tracker. I would like NOT to use a flight controller and power the 03 air unit directly into a battery or is it possible to plug into a spektrum receiver?? Any suggestions, tips or recommendations would be greatly appreciated!

so, the O3 can be powered by up to 6s but there is an issue. the O3 doesnt ramp up its output power without an 'armed' signal from a FC. a spektrum receiver doesnt output such a signal.

some people online have used raspberry pi's, arduinos, or whatever to add a signal, but at that point, i think its easier to just use a flight controller

For what you want to do, my own opinion is that I honestly wouldn't bother with the complexities of a flight controller.

Just get yourself a Seeeduino XIAO SAMD21 Arduino Microcontroller (~$5 USD), upload the arduino_DJI_03_RC_ARM.ino sketch to it, and then wire it up to your DJI O3 Air Unit. That will then pass an armed signal to the O3 Air Unit to force it into full power mode without the need for a full blown flight controller. You can find all the required details about how to do that in the Arduino DJI 03 RC ARM V2 GitHub link below...
