Quadcopter Build Tip: Install a capacitor on your battery lead!

This is something I must do on my KISS quad. Even though I already installed 2 LCfilters on the VTX and camera power wires, I still get severe disturbance on the videosignal when throttling up. I thought maybe it was because the Emax RB2600kv motors are too powerful, but according to the video it has more to do with the ESC's. Now going to install a capacitor next to each ESC, but need to order a few first.
