Just upgraded the above from a naked vista to a 04 litre. Was one hell of a squeeze due to the 04 being larger, had a print a plate to screw it to but got there in the end.
Just need to test fly it which is on the cards for tomorrow

Having just stuck an 04 lite in this I’m having a few issues. It worked fine to start had to turn off power save mode in googles as picture was naff but seemed to be fine after that.
Tried another battery and all I get now is green flickering light on the board, it’s like it won’t connect..
I know the light means it’s trying to pair with the goggles but when you put the goggles into bind mode nothing happens.. I’m powering it off a 5v pad so should be stable.
Has anyone else had this issue??? …
not tried the o4 myself but have you checked the FC can power it (those digital vtx are power hungry) - quick google says you ideally need 2A

Thanks for that Cedric, iv done a bit of research as I also a firefly 18 which has a 5v BEC.
One of the known challenges with running the DJI O4 on 1S builds is voltage—video feed can become unstable when battery voltage drops below 3.7V. Flywoo addresses this by including a 5V voltage regulator (external BEC), which delivers consistent power to the air unit. In my testing,
I’m a little confused so please bear with me, so the BEC is a 5v stabiliser but I’m running a 4S battery and soldered to a 5v pad. So wouldn’t that have a constant 5v supply thus not giving me the issue I have ..
Ok, just done a bit more digging and found the below, the Q I have now, is best to use VBat and step down to 9v or 5v pad and step up im thinking the later ?..

Verify power supply: Ensure the unit is receiving the correct power input. It requires more than $5$v, and some users suggest a voltage around $9$v from a dedicated step-up BEC is ideal.

I’m thinking something like this and bridge the 2 pads ..
This is all to do with the quality of the BEC tbh - and possibly the one you have onboard your FC is not powerful enough - or just not stable enough.
If you have the choice between powering the vtx with 5V or 9V - I would go 9V. Also best to stay away from the FC 5V pads (core issue is the FC onboard BEC providing the 5V pads is not of good quality)
Ideally find a good quality external BEC and connect it straight to the battery pads - for example - Matek Micro BEC 6-60V 5V/9V/12V Adjustable | HobbyRC UK
(you could even power the o4 with 12V using this one - more volts means less amps and less heat)
Ok, thanks for the feedback, I have a 9v one I can try now, I hear you in regards to the voltage, but I have to be mindful of size and weight of the BEC as this is an 80mm quad. and I’m limited to space ..
ll let you know the out come…

Ok it now works minus the OSD which iv double checked the wiring which is fine, just doing some googling now..
