These M3x8mm anti-vibration rubber shock absorber balls are made from high-quality red silica gel. They are designed to reduce the harmful effect of vibration on the flight controller, ESC and other sensitive components of an RC drone.
The listing says they are sized at M3x8mm, which is a good fit for M3 mounting holes, and that the silica gel absorbs and dissipates vibration effectively.
They are suited to many RC multirotors, drones and other applications where less vibration is important, and their red colour adds a stylish touch while giving crucial protection.
Precision M3x8mm size: a perfect fit for M3 mounting holes.
Superior vibration damping: durable silica gel absorbs and dissipates vibration.
Wide compatibility: RC multirotors, drones and other vibration-sensitive projects.
Red finish: a colourful, stylish look.
Effortless installation: quick and easy to fit.
A flight controller contains gyros and accelerometers that measure movement. Motor and propeller vibration adds noise to those readings, which can cause poor stabilisation, jittery flight or a drifting drone. A soft rubber ball between the board and the frame acts as a small spring and damper that filters out the high-frequency vibration before it reaches the sensors.
The balls are mounted at the corners of the board, with the screw passing through the ball. Do not over-tighten the screws, because a squashed ball no longer damps well, and keep the wires slack so that they do not bridge the board and the frame and carry vibration around the dampers.
A tidy, well-built airframe flies better and lasts longer. Check every screw after the first few flights, use thread-locking compound on metal fasteners, keep wires away from moving parts and inspect the frame and accessories for cracks after any crash. Small parts like these are cheap compared with the electronics they protect, so replace them as soon as they wear out.

The balls are M3x8mm and are made of red silica gel. The pack contains four pieces, which is enough for one board with four mounting holes.
The listing does not give the hardness or the load rating, so use them for light boards such as flight controllers and ESCs and not for heavy loads.
