Meaning to say one should leave the 5V USB power connected to ensure the "live mode" does not abort?

Nor has mine, me thinks that if the camera's batt is full enough to start a/v out by temporarily attaching a remote batt it will stay that way even if the camera's batt discharges to some degree. Can anyone confirm?

I have been able to unplug it every time. Trying to think about how much battery I've drained though. Usually I get it started and then it stays on (with A/V out) for the duration of my flying time. Typically about an hour or so. When I start it's definitely fully charged. Not that way by the end of flying though.

I can confirm. If the battery is FULL at the time you disconnect, it will stay in live video mode until the battery is DEAD. But if the battery is still charging when you disconnect, it will power off the camera immediately.

So if you power it from your rx permanently, isn't that safer? No chance of the battery going flat mid-air then... How many volts does an rx output anyway? Is it 5? I had a feeling it was 6. Am in an airport now so can't take a look

RC Receivers don't output a voltage, they're running from some other power supply. Many people put between 5 and 6 volts out of their regulators or BEC devices, which makes it suitable for driving the servos. For the GoPro, I would recommend staying very close to 5 volts, and not going much higher. I have wired a small 5V regulator into my camera harness.

I supply 5v to the GoPro from the Rx directly with no problem at all.

The Rx is feeded with the UBEC at 5v.

You certainly can provide power to the cam that way, in fact it's been done by installing a switch to an empty port on the receiver and to the cam. That way you can just turn power on and off to the cam. Each receiver port's pos and neg is connected to a bus and only the signal wire is independent.

NiCd + Mabuchi 550 was da bomb
According to Eyeofmine.com,

You can set the live video out to be of either SD or HD, how does one toggle this setting?

May be they mean component HD-output?

Nevermind,

I think the difference is whether you plug into the top HD port or the bottom TV port.

I'm making wire harnesses to make my GoPro an FPV cam.
May I know the pin-out of a 2.5 mm mini jack?

I have just drilled two holes in the side of the waterproof case. Now its not waterproof anymore. But I will fill it up the holes with silicone. The idea is to never have to take the GoPro out of its case. Charge, playback, fly FPV, connect to USB while in the case.

Then I'll strap a video TX to it and fly.....

Oops, I realized the 2.5 mini-jack supplied is a 4-pole (video and stereo audio). What I have bought are all 3-pole (video and mono audio). Can it still be used?
