    Yes. This is normal, and a side effect. If you want to fix it, you could make some sort of jumper to short the two pins, BAT2 and GND

    No, you have to clear the resistor off the pads, so it has to be empty. No solder bridges

    SCRATCH THAT, THIS ONE!!!!! SORRY

    In my last post, I highlighted the highside resistor, not the lowside. Removing that one will make it read zero, removing this one will make it read 3.3-0

    How do you know cooling is even a concern? Have you felt the components after flying? What motor/esc/prop are you using?

    I have a hunch that this is not the root problem

    If the motor doesn't get enough cooling, it will either fry itself or the ESC, permanently.

    If the ESC doesn't get enough cooling, the better ones will shut off, and the cheaper ones will fry...

    If you have old or worn batteries, yes this could be a problem.

    One explanation is that the prop stalls when you do a static test (because its at zero velocity), producing less thrust and thus...

    IMO, the obsession with LC filters has gone a bit overboard, you only need to add one if you've determined that your video quality is being harmed by ripple.

    But to answer your question, no, that...

    If you want it to shut up, you could short the ground and bat2 inputs together, so it'll read a constant 0v

    The can be calibrated of you're willing to desolder the resistors from the divider and find new ones to adjust for the error in the voltage reference.

    In short, no. There's no easy way around

    I actually don't have my SSOSD anymore; I fried it long ago. But from looking at the traces, I would guess that the bottom is ground. Of course, you should check it with a multimeter

    Do you have any capacitors lying around? Either aluminum electrolytic ones or ceramic ones? Preferably in the 1uF-100uF range?

    This will filter the PWM to be a more stable voltage. The two ends...

    Without knowing that receiver, I would guess that it is outputting PWM and that the ADC on the OSD is only getting glimpses of the waveform.

    Yes, basically. However, there are probably lots of pins that will change when the TX goes on or off. If you have an oscilloscope, you could narrow it down better. Also, it might not be an analog...

    I did a little bit of googling, and I couldn't find the RSSI pin for that RX. Unless you can find it yourself by more googling or poking around with a voltmeter, you're out of luck

    Do you happen to have an oscilloscope handy? What camera are you using?

    My theory is that this type of OSD can't handle a capacitively coupled video signal

    As a scale glider pilot, I often don't even need to look at the airspeed indicator, because its so obvious with cockpit noise.

    You might try a microphone. A whole lot simpler and cheaper

    I had to go through the exact same thing you're going through, so I can save you a ton of work :)

    The BMP180 works, but it gives much more noise than the MS5611
