Make all necessary servo connections to your receiver and/or Aura. Install the two 
recommended receiver batteries as needed to achieve the proper CG. This picture uses 
the rudder servo in the tail with a push/pull setup and the DA-70 engine. 

In the image above, we are using the Aura 8 Pro with dual Futaba S.Bus receivers. One is 
mounted in the tray and the other behind and above for maximum signal strength. 
Reference your receiver’s instruction manual for mounting details.
