RC Onboard Electronics

Onboard electronics are the components that live inside a model and turn a pilot's stick movements into action at the control surfaces and power system. This section serves as a gateway to the receiver-side gear that keeps a radio-control aircraft flying under command.

What This Category Covers

Where a transmitter stays in the pilot's hands, everything on the aircraft side counts as onboard equipment. That includes the parts that receive the radio signal, distribute power, move the controls, and tie the system together with the wiring and connectors that carry the signal safely.

Reliable onboard electronics matter because every part shares the same job of keeping the model responsive from takeoff to landing. A loose connector or an underpowered component shows up as a control glitch in the air, so builders tend to favor clean, well-secured installations.
