No amount of PID tuning and new Betaflight releases will fix your vibration problems if you have a bent prop. This is a huge thing in the stability of your quad. However, if you can see the image and the OSD, but have static lines, then it’s the video transmitter. If the video feed is black, but you can still see the OSD, then its your camera that needs to be diagnosed. Also, make sure that your camera cable, video transmitter cable, and wires are secured. The vibrations in the quad during flight interfere with the connection of the antenna, which decreases range, and may even put your video transmitter at risk of burning out. If it is even slightly loose, or wiggles a tiny bit, then tighten it or get a new antenna. Check ConnectorsĬheck your SMA antenna connection on your FPV transmitter. Jello is when the image in your FPV gets slightly distorted and shifted because of the way many cameras process their image. Also, it can cause “jello” in your video. Vibrations in your quad frame can disrupt the operation of your FPV equipment. An FPV BEC basically does the same thing as powering your FPV system from a filtered pad on your PDB.
A better way t counteract interference would be to add a low ESR capacitor. These two solutions are relatively outdated and not recommended anymore, but adding an LC filter to the power system can help a bit. Yet another solution to eliminating electrical noise in your quad is to add an LC filter and/or an FPV BEC (battery elimination circuit). Try to keep your ESCs as far away as possible from your flight controller and FPV equipment. These wires can generate EMFs, or electromagnetic fields, which causes interference in the FPV video feed.
Keep ESCs Far AwayĮSCs operate at high voltages and frequencies, carrying current and signals through wires in our quads. If this is not possible, try to connect them as close to each other as possible. For best practice, connect the more critical part, the FPV system to a common ground pad. These affect the pad’s resistance, capacitance, and inductance, all of which can cause voltage and current differences throughout your power system. Different pads on the PDB may have different thicknesses, lengths, or shape. The reason for this is because not all ground pins are the same in a mini quad. If possible, connect your FPV camera and FPV transmitter to the same ground pad on your PDB. A great video explaining more in depth about capacitor placement and installation can be found here: https ://Have a Common Ground When installing a low ESR capacitor, you want to solder it as close as possible to the battery. An example of a common one is a 1000uF 25-35V low ESR capacitor. Look for a large capacitor with a sufficient voltage rating. A small interference may cause static to appear, and in some cases, can block out the whole signal. Not surprisingly, this has detrimental effects to the FPV system.
They are constantly pumping out high current to the motors at high frequencies. The ESCs in your quad generate a lot of electrical noise. White line static is electrical interference, whereas black line static is usually due to a lack of power going to your camera and/or video transmitter. There is white line static, and black line static. Also, objects that are in the way of the line of sight between your goggles and video transmitter can cause multi-pathing, resulting in a low-quality video signal. This can vary from electrical noise coming from the ESCs, to vibrations from a bent prop.
The most common causes for a bad FPV video feed are caused by electrical and/or mechanical disruptions in the quad.
