Green ring on wire to RX on hobbywing
 

Whats the green ring for that the wire to the RX goes through for
is this ring to prevent interference, can I move it closer to the esc so i can thread more cord though my chassis??

from what I was told by a fellow member running these esc's you can just take it off.

I found its a ferite ring for reducing elctro magnetic interference but with 2.4 Ghz you dont really need it.(thats what the plain guys say, they add them to servo wires to reduce glitching.)

i saw this thread and remembered where i first saw a ring

The output lead of the BEC also wrapped through a torroid choke to further reduce any switching noise that might be generated by the BEC.
