Keep your wires neat!
Experienced modelers go to great pains to tie down their servo and throttle leads, and some find unplugging a Castle controller from the receiver disrupts all their work. Many have asked for something like a Y connector that gives an open lead for easy Castle linking, but a traditional Y harness doesn't work when the other branch of the Y is connected to a receiver - the signal line must be disconnected from the receiver.
Quick Connect Duo detects the presence of a Castle Link adapter on the free lead and switches the controller's signal line from the receiver to the Castle Link.
Quick Connect Duo supports all Castle Link capable ESCs but is designed specifically for use with Castle ESCs featuring AUX wire technology.
