I actually use a very 4" extension and take the red wire out of that so I can just unplug the ESC side and plug it into the link. That way the ESC wires are all always intact.
I use Bec pro with castle quick connect.
This way esc wire is never unpluged from receiver as CQC is got separet wire that u plug to Castle link! Very easy to use.
Red wire from ESC u leave it, but u unplug red wire on the quick connect and viola.
