If you are installing a four-stroke in your model you will also
need to locate the following items.
 Step 2
Cut the tip from the included threadlock vial. Slide a #8
washer on a 8-32 x 4/3-inch machine screw. Apply a drop of
threadlock on the threads of the screw. Prepare four screws
at this time.
 Step 3
Attach the engine mount to the fuselage using the four
screws prepared in the previous step.
 Step 4
Locate the engine mount straps. Note that one side is
smooth, while the other side has dimples. The smooth side
will face up and away from the engine when installed.
 Step 5
Slide a 8-32 x 1-inch machine screw through the engine
mount strap from the smooth side. The screw then goes
through the rear hole of the engine mount. Thread a 8-32
locknut on the screw from the underside of the engine
mount. Install both engine mount straps at this time.
 Step 6
Slide the engine into position. The engine mount straps will
be on the top of the engine mount lugs as shown.
