So, I also want to use the Unity / VX1 PPM configuration, and need to solder the blue wire onto the thing. But why can I not use the BAT+ pin of the AUX JST-Phase2 plug? (Bottom left) Or can I?
As long as you aren’t exceeding the 150mA rating, no issue.
I did get a slightly different voltage reading there vs on the Bluetooth app and vs measured reading from battery.
yes u can, that’s what im using
Works just fine for me. So far at least. I’ve got the VX2 Pro though, if that can have something to do with it.

Same here
Using VX1 in PPM mode with Unity
It’s fine since 2500km
Hopefully it will stay like that 
Not using battery reading wire at all, I don’t think I can rely on 4 LEDs, Metr and DavegaX ftw

To test this once more, I have both VX1 and VX2 connected to my board atm, as long as the control mode is set to eiter one PPM/UART I’ve seen no issues, It starts to be an issue if control mode is PPM and UART
