In RC (radio-controlled) models, male-to-male JR extension leads, also known as servo extension cables, are used to extend the connection between components like receivers, servos, and electronic speed controllers (ESCs). These leads are particularly useful for connecting devices with standard 3-pin JR/Futaba connectors, allowing for flexible placement of components within the model and enabling custom wiring setups.

The primary difference between Futaba and JR servo connectors lies in their�keying/polarity and housing design.�Futaba connectors have a prominent tab on the signal (usually black) wire side of the female connector to ensure correct polarity, while JR connectors typically have beveled corners on the male connector and angled tabs on the female connector to help with alignment.�Futaba plugs can often be modified to fit JR connectors, but JR plugs may not fit Futaba receivers without modification.

Futaba and JR connectors are generally compatible�due to their similar pin spacing and overall size, though Futaba connectors have a keying mechanism that might require modification to fit into a JR connector housing.�
