Step 20.
Note where the throttle control linkage is in relation to
the 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 position
and the throttle servo arm is centered. Mark where the throttle
linkage passes over the throttle servo arm. Use “Z” bend pliers to
make a “Z” bend at the mark. Attach the throttle linkage to the servo
arm (you may have to remove the servo arm to install the arm onto
the “Z” bend, then reinstall the servo arm onto the servo).
Step 1.
Using a Moto-tool, grind out the prop and cooling
openings in the front of the cowl. A template is provided for the
prop opening. Next, cut out the large “U” shaped opening in the
bottom of the cowl so it will slide over the fuselage and part of
the landing gear. This will also allow for airflow and exhaust
flow. A template for the cowl opening is also provided.
Step 2.
Make a template of the cylinder head of the engine you
are going to mount in the Edge 540. Mount the engine and place
the template over it. Use a piece of cardboard or heavy paper that
can be taped to the fuselage and folded back. Remove the
engine, fold back the template and slide the cowl over the
fuselage. Unfold the template so it rests on the cowl at the
position where the engine cylinder will be located. Mark the cowl
for the engine cylinder opening. The same process can be done
to locate where the needle valve will exit the cowl.

Parts Needed
Tools and Adhesives Needed
After connecting the throttle linkage to the servo arm, check again
to make sure the throttle barrel is at 1/2 open position when the
throttle arm centered and the transmitter throttle stick is at 1/2
throttle. This will allow for minor adjustments to the carburetor by
screwing the nylon clevis in or out on the threaded rod.
