power filter

If you see noise and static in the video stream when powering up the motors, your motors/ESCs interfere with the video system. You can run separate batteries, or use a power filter. This one here from RMRC works great. If you want to make your life a little easier, get the pig tail too.

    Hi Benedikt!
    what are some ideas of hooking up a separate battery to get rid of the noise issue. I'm trying to set a nano qx with pico camera and 1.3 ant and am getting the horizonatal lines but at times it gets real fuzzy. I'm just thinking out loud, but would that have more weight? Just thinking of a better solutions until I get that power filter you mentioned. Thanks!

    With that gear on a nQX, you are already running on the limit in terms of weight. The power filter I linked above is cheaper than most single cell packs, and it's lighter and easier to operate.
    Having two batteries to charge and swap gets old quickly. You would need a very small secondary pack (~100mah) to keep the weight down. That will give you maybe 10 minutes of runtime, depending on consumption of your components. And that means you either swap secondary pack every time you swap flight pack, or you run the risk of suddenly sitting in the dark.
    Your "fuzzy" might have different reasons too. Hold in the quad in your hand, give it full throttle. Any problems with motor/ESC interference should be visible now. If that shows different or fewer artefacts, you might simply run out of range.

    In any case, I found the voltage regulator to be the best solution. The only downside is that you need to make up a wire harness. I usually make harnesses with 4 plugs, to connect FC (grab the flight pack power from there), v-reg, cam and Tx. It's fiddly, and mistakes are easily done. Take me usually around an hour..

    Hello Benedikt!
    I just reread my first thread and it sounded a little abrupt. Just wanted to say I love what your doing here. Me and a couple of friends are also trying the get micro fpv'ing to take off here in San Fernando Valley, which is where I live, and have just also started a group on facebook called "Micro FPV Pilots of the World". Here's a clip from one of our flights...

    Anyways, I actually did run some test as you suggested and the faint lines do show up when I do a full throttle. I did try the power filter, but accidentally burned it,which was totally my fault, so now I'm ordering 5 more. But while searching for some kind of noise suppression I ran into some OD 12.5mm rings. http://www.readymaderc.com/store/index.php?main_page=product_info&cPath=11_15&products_id=325. They weight about 2g and I was wondering if you had any experience with these, how to install one if you do, and if they would help hide the lines?

    I'm currently at 34g with my nano QX 3D.

    Again thanks for the suggestions, love what your doing for this sector of quads, keep up this good work, and talk wtih you soon.
