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 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.
The Quick Connect is recommended for the following ESCs:
Surface - Sidewinder v1/2/3/SCT, Sidewinder Micro, Sidewinder Micro 2, Mamba Micro Pro, Mamba Max, Mamba Max Pro, Mamba Monster, Mamba Monster 2.
Air - Phoenix ICE, Phoenix ICE HV, Thunderbird, Phoenix, Phoenix HV.
Note: If you have Castle ESCs with AUX wires or an on-board 6+ amp BEC you must use Quick Connect Duo.
Note: Neither Quick Connect, nor Quick Connect Duo will work with the Field Programming Cards when used as a standalone programmer. It will ONLY work when using the Field Programming Card as a Castle Link adapter.
