    I bet it will do, I don't even look at the capacitors, just making sure their voltage is above required, and so far all of them worked
    If you're a noob, copy 1:1 what somebody already flies without too much questions, you'll find the answers later.

    mine works fine! tested it yesterday and damn, what a smooth image! doesn't matter how many throttle or servo input i give, no lines on screen!

    Awesome! That's how everyone's video should be, no reason to accept second best.

    Sander Style LC Filter - remove lines in your video

    Here's a preview of my screen

    Had some probs with my naze fcb, turns out that i didn't have enough juice to power all the components.
    Now with an seperate BEC its all good!

    I'm not Alex, but I believe that recommendation was based on the fact Shottky diodes have a lower voltage drop compared to standard silicone diodes (less power loss) and they have zero recovery time which is important when trying to reduce impulse noise which is the reason for using such a filter.

    The size of the capacitor required is determined by the amount of power the load will draw, the larger the draw the larger the capacitor needed and within reason a larger capacitor larger then needed can be substituted and will still work.

    Hi Robo, looks great, and just what I need for my mini quad...... is there any chance you could let us know the parts required, and a small tutorial? - pretty please?

    I don't know what parts are there, found them in a junk, used them and it works First page explains everything, so not much to add... Negative to capacitor and out, positive wrapped around ferrite, to capacitor and out it comes filtered.

    What is the device between the leads of the cap?

    I noticed on the lc filter that I got from you that there is no inductor just the diode and two caps. Is this because that diode acts as the inductor?

    Thanks
