3. Drill 1/8" [3.2mm] holes through the valve covers
and the crankcase for the valve guide tubes.
❏
4. Fit, then glue the guide tubes into position with
medium CA applied to the back side of the engine.
❏
5. Use blocks or wood or something similar to
support a lead pencil so the tip will be 1-1/4" to 1-3/8"
[32mm – 35mm] from the workbench. Use the pencil
to draw a line around the inside of the cowl.
❏
6. Without using any glue, fi t the replica engine down
into the cowl, aligning it so it is level with the line you
drew around the inside of the cowl.
❏
7. Carefully mount the cowl to the fuselage without
moving the replica engine—this may require removal
of the drive washer from your engine.
❏
8. Be certain the cutout in the replica engine aligns
with the engine. Make any adjustments necessary.
❏
9. Once satisfi ed with the fi t of the replica engine
in the cowl and around the engine, remove the cowl
with the replica engine. Wick thin CA around the replica
engine to permanently glue it into the cowl.
❏
10. If necessary, enlarge the hole in the middle of
the replica engine to accommodate the drive washer
on your engine. Here’s the fi nished installation.
❏
11. Now you may cut and connect the fuel lines.
The tank has been plumbed so there will be one line
that connects the vent (on the top of the tank) to the
pressure fi tting on the muffl er, another line connecting
the tank to the carburetor and a third line for fueling/
defueling. Close the fueling line (which can be reached
through the bottom of the cowl for fueling and defueling)
with an included fuel line plug and guide it through a
hole in the cowl.
❏
12. Note that an aluminum propeller hub is included
with this kit. It may be used in place of the propeller nuts
that come with your engine. Since it is not a locking
system, however, be certain to use a small amount of
threadlocker on the threads and securely tighten the
hub with the included torque bar.
FINAL RADIO/RETRACT INSTALLATION
Refer to this photo while fi nishing your installation.
❏
1. Take a few minutes to plan and visualize the rest
of your radio installation, thinking about accessibility of
the on/off switch and charge receptacle from outside
the model. Mount the Rx battery and receiver using
whatever methods have proven to work for you—1/4"
[6.5mm] R/C foam is recommended for the battery held
