Stage 6—Installing the Engine
Hint: When secured, grab hold of the engine—you should
be able to pick up the airplane. This is a check to be
certain the engine is tightened securely. You need to
continually check the tightness of these screws after
the first few flights to be certain they stay tight.
Step 2. Center the throttle servo and adjust the clevis (screw
in/out) until the carburetor barrel is 1/2 open when the clevis is
attached to the outermost hole on the throttle servo arm.
Note: Place a piece of the provided fuel tubing over the
clevis of the throttle linkage to prevent the clevis from
accidentally opening.

Step 3. Install the muffler using the screws provided with the
engine. Note: Some engines use Allen type hex bolts, and the
hex wrenches are included with the engine. Insert the screws
through the engine and mount the muffler. The muffler screws
must be very snug to prevent loosening under vibration.
Step 4. Note the two colors of fuel tubing, clear and orange.
Attach the clear fuel line to the fuel nipple. Attach the orange fuel
line to the pressure nipple on the muffler.
