Waterproofing Drone and FPV Electronics

Flight controllers, ESCs, receivers and FPV boards face rain, humidity, condensation and constant vibration. A thin coating lets you fly in more conditions and extends the life of sensitive electronics.

Why drones need coating

A few drops of water on a powered flight controller can cause a short and a crash. Coating creates a moisture barrier so light rain, fog and condensation are far less likely to cause damage.

What to coat and what to mask

Coat flight controllers, ESCs, receivers and VTX boards. Mask connectors, antenna pads, USB ports and any sensors that must stay exposed.

Keep it light

Drones are weight-sensitive. A thin, even layer protects without meaningfully changing weight or balance; reserve thicker layers for edges and repair points.

Vibration and durability

Vibration loosens solder joints over time. A coating that reinforces joints and resists abrasion helps the board survive repeated flights and handling.

Liquid PCB Plastic Coating is applied at room temperature by dipping, spraying or brush — practical for protecting FPV and drone electronics in the workshop or the field.
