So, you’ve been proudly flying your ParkZone P-51D
around your buddies. One by one, you’ve mastered many of
the maneuvers that you would use if you were in com-bat
with your friend, the one who always says he could take
you with his F-27 Stryker.
What he doesn’t know is that you are about ready to
make him eat his words. You were thrilled to find out that
with some minor modification, you could make your
Ferocious Frankie ready to rule the sky with the HobbyZone
Sonic Combat Module™. Now, you just have to find a way to
get your buddy to meet you at the field.
ParkZone’s rendition of the P-51D Mustang is a thrill to
fly. You can almost imagine the feeling of flying over
Europe in the mid '40s, looking for the FW-190 and
protecting the long-range bombers. Now you can capture the
feeling of combat with only a few small steps.
Items Needed:
• Small Phillips screwdriver (#OO)
• Medium Phillips screwdriver (#1)
• Velcro or servo tape
• Scissors or hobby knife
• Sonic Combat Module “SCM” (HBZ4020)
• X-Port extension (included with ParkZone P-51D, and part
number PKZ1529)
• Wire snips
Step 1. Remove 4 small screws that hold SCM
together. Next pull apart SCM to get to the two small
screws that secure clip of SCM. (Note: you will need to
remove two small pieces of tape that cover the screws.)
Remove the two screws and clip. Reassemble SCM.
Step 2. We recommend clipping all four sides of
the curved mounting tabs on the SCM. This will allow it to
fit better against the fuselage.

Step 3. Cut 5 or 6 small pieces of servo tape
(about 1” long). Begin stick-ing these on top of each
other in the middle of the SCM (between the cut tabs) and
until the height of the tape has exceeded the height of
the remainder of the tabs that you cut down.

Step 4. Remove wing of your P-51D in order to
access the Rx/ESC unit. DO NOT unplug aileron extension.
Step 5. Locate X-Port™ extension (included with
P-51D, or part number PKZ1529). Attach lead into Rx.
(X-Port plug is located in middle of Rx/ESC unit.)

Step 6. Prepare to mount modified SCM on right
side of fuselage. The correct location will be directly
above wing fillet (approx. 4” behind exhaust stacks on
cowl).
Note: Once SCM is taped to side of fuse, it may cause
paint to peel when SCM is removed.
Step 7. Attach SCM to X-Port extension. Trial
fit SCM to side of fuselage, making sure you have enough
slack to allow ALL connectors to fit completely inside
fuse.

Step 8. Reattach wing. Mount SCM to side of
fuse. Make certain it is secured properly.

Step 9. Test Sonic Combat Module per the
instructions included with the SCM.
Warning: Participating in combat can put your aircraft
in jeopardy. Use caution and avoid flying at too low of an
altitude.
Combat is at your own risk!
Note: If you prefer, it is also possible to make a
small hole in side of fuse where SCM lead could go
through. This would allow you not to have the lead exit
between wing and fuse, but will obviously cause a
permanent hole on the side of fuse.
