Now run all your fuel lines, the outlet nipple of the Flowmaster tank goes to the 
carburetor, the top elbow with the fuel line connected is your fuel/defuel line and it
goes to the fuel dot, the remaining top elbow is your vent line. I recommend 
looping it around your tank then out the bottom of the airplane, typically we go out
the bottom of the cowling.

17. Now is a good time to install your receiver, batteries and locate your switches  
as desired, I recommend using the precut switch locations. 

18. I saved the rudder servo installation for last, the reason is due to the center of 
gravity. Inevitably this airframe will have every engine combination from a 80cc
