I have been trying for some time to get decent FPV video out of my quadcopter. From my initial flight, when the video was totally useless, I've taken as series of small steps, each time the video quality improved a bit. I started with installing a cloverleaf antenna on the vtx, followed by putting a wire mesh around the vtx. Then I added cloverleaf antennas on my receiver/monitor. I've seen improvements in each step, but after watching some videos on YouTube, I've decided to try one last thing: adding low ESR capacitors across the power leads of the ESC's to shunt noise to ground. So, I ordered some 25V 470 microfarad capcaitors from Amazon, which arrived today. While in theory this should be a simple installation, it is turning out to be a major job, involving essentially disassembling the aircraft. I have to remove each ESC, solder a capacitor to the power and ground leads and put new heat shrink on the connectors/capacitor leads and gingerly reinstall the ESC. Here is the #3 ESC with its capacitor: And here it is, back in the chassis: The #3 ESC is on the right. Before removing, I had to mark the leads going to the motor so I don't have to retest the motor spin direction again (though I probably will to be thorough). As you can see from the congestion, this is going to take awhile. I hope the effort will be worth it! When I'm done, I will post a video of my results.
