STEP 1 - REMOvE NITRO COMPONENTS
1. REMOVE NITRO COMPONENTS
Remove the following items from your buggy (see Figure 2).
• Nitro Engine
• Steering Servo and Mount
(keep for all conversions)
• Muffler
• Mechanical brake assembly
• Fuel Tank
parts
• Radio Box
(keep for Losi 8ight)
• other parts specific to the fuel
• Throttle Servo
engine
(keep mounting screws)

2. CLEAN BUGGY
If you are starting with an old buggy that is full of greasy dirt, we
highly recommend that you thoroughly clean your buggy.
for STEPS 2-5: Refer to the vehicle-specific sheet that
is located in the bag with the motor adapter plate.
STEP 2 - INSTALL STEERING SERvO
For Losi 8ight Vehicle: refer to Figure 16 (on specifics sheet).
1. REMOVE & MODIFY SERVO TRAY
Cut off the part of the servo tray that holds the throttle servo. This is
best done with a dremel Tool with a carbide cutting wheel. Round
off the sharp corners where necessary — see Figures 3 & 4.
Make sure that the three or four (depending on kit) servo tray
mounting post holes remain intact.

2. RE-INSTALL STEERING SERVO ASSEMBLY
Install steering servo assembly to chassis and hook up steering
linkage. Refer to Figure 14 on specifics sheet (or Figure 15 for
dual battery set-ups if applicable).
• For Associated RC-8: You can either mount the steering
servo upright (vertical) or on its side (horizontal).
STEP 3 - InSTALL BATTEry BoX
For optimal side-to-side balance and vehicle performance,
Novak recommends installing one battery box. Novak's battery
box can accommodate two, 2S Li-Po packs, which provides excellent
power and runtime.
For Dual Battery Box Setups: Refer to Figure 15 on the backside
of the vehicle-specific sheet for dual battery box instructions for the
oFNa 9.5 (#5015) and Kyosho inferno (#5013) series buggies. The
other buggies require major modifications to mount a second battery
box, and we don't recommend it.

used for comparison.
The following instructions are for a single battery box installation.
1. LOCATE POSITION FOR BATTERY BOX
For the best side-to-side balance, we recommend installing the
battery box on the right side of vehicle (left side for Losi 8ight).
2. SELECT PROPER BATTERY BOX & HARDWARE
On the bottom of the battery box, there is a LEFT and RIGHT
notation. Follow the list below to know which box and what hardware
is used to correctly mount the battery box in your vehicle.

3. LOCATE & DRILL BATTERY BOX MOUNTING HOLES
drill completely through the two mounting screw holes in the
a
battery box with a 3.6mm (or 9/64") drill.
b. Position the battery box in the buggy. The front of battery box and
the battery wires must clear the steering servo and its linkages.
The back of the battery box must go inward as far as possible
so that it will clear the body. Box must be at least 4mm (or 5/32")
away from the spur gear. Refer to Figure 14 (on vehicle specifics
sheet) for correct location.

c. With the battery box in the correct location (refer to Figure 14
on specifics sheet and double check this location), spot drill the
first hole (front or back) with a 3.6mm (or 9/64") drill bit, going
down through the hole in the battery box — Refer to Figure 6.
d. From one of the Battery Box Hardware Bags, gather the needed
screws and washers — see table & Figure 5. A button head (BH)
screw mounts the battery box to the plastic stone guard, and the
flat head (FH) screw mounts battery box to the metal chassis.
e. After you have marked the hole, remove box and drill a 4mm hole
in this location. Using a 2.5mm Hex Wrench, mount box with the
proper screw (see table) and correct number of washers. Snug up
screw. This allows you to more accurately locate second hole.
f. Repeat steps c through e for the second battery box hole — see
Figure 7 for completed battery box.
Note: If hole is in the metal chassis, the hole must be countersunk
on the bottom of the chassis.

When you are done, you should have a stable battery box with
little rocking motion.

STEP 3 INSTALL BATTERY BOX (Continued)
5. INSTALL BATTERY BOX HOLD DOWN STRAP
With a 2.5mm Hex Wrench, screw one end of the battery strap
a.
into battery box with a M4x20 BH screw — refer to Figure 7.
b At the other end, screw in an M4 post and use a body clip to
fasten the battery strap.
c. The size of the batteries will determine which direction you place
the strap on the box. For thin batteries, attach one of the included
plastic spacers with an M3x8 BH screw on each 3mm spacer
hole — refer to Figure 8. Tighten using a 2.0mm Hex Wrench.
Note: The M4 post should be placed on whichever end of the battery
box that has body clearance for it, which is usually the back.

STEP 4 - InSTALL BruSHLESS MoTor
A Novak 550-size brushless motor is required for this
conversion kit. If the motor does not have a 5mm output shaft,
the motor needs to be upgraded
