Section 15: Installing the Control LinkagesStep 20. Note where the throttle control linkage is in relation tothe throttle servo arm inside the fuselage. You will need to make a“Z” bend at the end of the rod and attach it to the throttle servo arm.Make sure the engine carburetor barrel is in the 1/2 open positionand the throttle servo arm is centered. Mark where the throttlelinkage passes over the throttle servo arm. Use “Z” bend pliers tomake a “Z” bend at the mark. Attach the throttle linkage to the servoarm (you may have to remove the servo arm to install the arm ontothe “Z” bend, then reinstall the servo arm onto the servo).CONTINUEDAfter connecting the throttle linkage to the servo arm, check againto make sure the throttle barrel is at 1/2 open position when thethrottle arm centered and the transmitter throttle stick is at 1/2throttle. This will allow for minor adjustments to the carburetor byscrewing the nylon clevis in or out on the threaded rod.Section 16: Attaching the CowlingParts Needed• Fiberglass cowl• 4-40 button head screws (4)• Red trim tape• Rubber grommets (4)• Fuel Dot (HAN115) (optional)Tools and Adhesives Needed• Drill• 1/16” drill bit• Masking tape• Moto-tool with sanding drum• Carbide cutter• Sanding stick (medium)• Ruler• Felt-tipped pen or pencilStep 1. Using a Moto-tool, grind out the prop and coolingopenings in the front of the cowl. A template is provided for theprop opening. Next, cut out the large “U” shaped opening in thebottom of the cowl so it will slide over the fuselage and part ofthe landing gear. This will also allow for airflow and exhaustflow. A template for the cowl opening is also provided.Step 2. Make a template of the cylinder head of the engine youare going to mount in the <strong>Edge</strong> <strong>540</strong>. Mount the engine and placethe template over it. Use a piece of cardboard or heavy paper thatcan be taped to the fuselage and folded back. Remove theengine, fold back the template and slide the cowl over thefuselage. Unfold the template so it rests on the cowl at theposition where the engine cylinder will be located. Mark the cowlfor the engine cylinder opening. The same process can be doneto locate where the needle valve will exit the cowl.37
