From what I understand, the futaba series of receivers put out less control signal that other receivers. While the servo voltage may be 6.0 volts or more, the control signal is usually around 3.3 volts. You may have trouble due to signal loss in the extension.

Try first plugging the Y cable directly into the receiver and see if it works.
If no, then try a difference receiver to see if it works.
