Look at his link. It is the FS8 receiver without the Co-pilot components, but with the annunciator panel. I do not think that either the Fortress or the Quantum receivers will support the annunciator panel. The annunciator is very handy. It will record the history of the signal received during each flight and it is also a handy voltmeter. One can read the on-board voltage while exercising the servos. Perhaps not as good as a loaded meter, but much better than reading the voltage with no load on the batteries.
Read the info with the receiver about determining the quality of the signal your Tx is putting out. May be helpful.
