I believe you use two servos, one connected to the up/down and the other 
connected to the right/left outputs of the reciever.  Each is connected to 
a DPDT switch or a MAG style switch pair that serve as the up/down and 
left/right switches on the diagram.


You could also do it electronically I expect, but you'd have to interpret 
the pwm signals from the receiver.
