rv voltage regulator?

Both my video TX and camera are powered by 12 volts, so I've been using a tiny 350mah 3s lipo. But I would like to power them off the main flight battery, so I ordered the Range Video linear 12volt regulator. My question is, will this hold a steady 12 volts to my camera and VTX even as my flight battery drops as I fly? And will it filter out the noise that the esc and motor generate?

It will filter the noise but it won't hold a steady 12V (it's drop-down, not step-up).

The anyvolt are known to be noisy so make sure you do appropriate range testing to ensure you aren't affected. I have used one with success so you must try and see for yourself.

Hey bracky72,
I know that success can vary drastically setup by setup, but what have you had the best luck with? I know you've gone a mile up, so your opinion holds quite a bit of weight with me. Are you running power from the balance plug or from the dean's?

For a 12 volt system I grab power straight from the esc dean and run it through a LC filter and then on to the tx and camera.

I've never noticed any loss of performance as the lipo drains to empty so I don't bother with a step up regulator. Best to keep things simple if you can.

If I was running 4 cells I would use one of those nifty switching regulators from nghobbies. I've been meaning to pick one up to try it.

bracky: highly recommended you can get the RECOMs too and add a 470uF cap and 100uH choke. Works very well.
