Twisted servo extension cables offer several advantages, primarily related to minimizing electromagnetic interference (EMI) and improving signal integrity. The twisting of the wires helps to cancel out noise and reduce crosstalk, leading to more reliable and stable connections, especially in demanding RC applications. 

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.
