Novak Duster (1960) - Manual (Page 2)

Refer to Figures 5 and 6
1. INSTALL MOTOR CAPACITORS
Electric motors generate radio noise that can interfere
with your receiver and cause radio problems. Included
in the speed control's accessory kit are three 0.1µF (50V)
non-polarized, ceramic capacitors. These capacitors muse
be installed on every motor to help reduce the noise gen-
erated by the motor and also to prevent possible damage
to the speed control. Extra 0.1µF capacitors available in
Novak kit #5620.
Solder 0.1µF (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (
- ) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (
- ) motor tab & GROUND tab*.
Negative (-) Motor Tab
0.1µF Capacitors
Optional Schottky Diode
Positive (+) Motor Tab
Ground/Motor Can *
* If your motor does not have a ground tab, solder the capacitor
leads to the can of the motor.
2. CONNECT SPEED CONTROL TO THE RECEIVER
After the proper input plug plastic has been installed to
match the receiver (Refer to STEP 1 on front page), plug
the speed control into the THROTTLE CHANNEL of the re-
ceiver.
3. CONNECT SPEED CONTROL TO THE BATTERY PACK
Plug the Tamiya connector from the speed control into
the Tamiya style connector on a fully charged 4 to 10 cell
battery pack (1.2 volts/cell). The black wire is negative (-)
and the red wire is positive (+).
4. CONNECT SPEED CONTROL TO THE MOTOR
The Duster II is not recommended for use with motors
having fewer than 12 turns. Plug the bullet connector on
the red wire (+) of the speed control to motor positive.
Plug the other bullet connector, on the blue wire (-), to
motor negative.
TIP: Twisting the BLUE & RED motor wires one or two times
around each other, as they go to motor, can help reduce radio
noise that may be emitted from the power wires. See Figure 6
5. OPTIONAL USE OF SCHOTTKY DIODE
The Duster II does not require an external Schottky diode.
It is recommended that an external Schottky diode be
installed if using a low turn modified motor Using one
will increase the efficiency and reduce the operating tem-
perature of the speed control.
Schottky diodes are available in Novak kit #5640.

HOOK-UP INSTRUCTIONS
For proper speed control operation, the basic throttle channel
adjustments for the transmitter are:
1. Set HIGH ATV or EPA to maximum setting.
[Controls amount of throw from neutral to full throttle]
2. Set LOW ATV, EPA, or ATL to maximum.
[Controls amount of throw from neutral to full brakes. NOTE:
Reduce this after performing One-Touch Set-Up to reduce
amount of brakes]
3. Set EXPONENTIAL to zero.
[Controls the linearity of the throttle channel]
4. Set THROTTLE CHANNEL TRIM to middle setting.
[Adjusts the neutral position of speed control. NOTE: Increase
or decrease after performing One-Touch Set-Up to adjust coast
brakes––can be used to give braking in neutral trigger position]
5. Set MECHANICAL THROW ADJUSTMENT to position with
2/3 throttle and 1/3 brake throw.
[Adjusts pistol-grip transmitter’s throttle trigger throw]

SPEED CONTROL PROGRAMMING
INSTALLING BRAKE LIGHTS
Equipped with built-in brake light circuitry, the Duster II in-
cludes Novak's Brake Light LED Kit for easy installation of
brake lights. Brake Light Kit includes: two LEDs, two brake
light mounting brackets, JST connector harnesses, double-
sided mounting tape, heat shrink tubing, and screws.
TO CONNECT BRAKE LIGHTS TO THE DUSTER II
Refer to Figure 7
1. Strip about 1/4" of insulation off both the small (26 gauge)
red and black brake light wires that exit the back of the
speed control.
2. Remove pre-stripped end of insulation from JST connector
harness and slip heat shrink tubing over each wire.
3. Connect the JST harness to the speed control's brake light
wires by twisting or soldering the two wires. Black (nega-
tive) to black and red (positive) to red. NOTE: If connecting
two LEDs, twist or solder the red wire of both JST connector
harnesses to the speed control’s single red brake light wire.
Do the same for the black wires.
4. Slide the heat shrink tubing over the twisted/soldered wire
connection. Shrink the vinyl tubing with a heat gun or light-
er. This will seal the connection and protect the ESC from a
short that may occur if wires are left exposed.
5. Insert the LED into the orange mounting bracket so that
the two metal leads snap through and exit the two small
holes on the bottom of the bracket. NOTE: The metal lead
on the flat side of the LED is the positive lead.
6. Connect the LED to JST connector by inserting the metal
lead on the flat side of the LED to the “RED” slot (positive)
and the other lead to the “BLK” slot (negative). NOTE: Plug-
ging the LED in backwards will not cause damage but the
LED will not work.
MOUNTING THE BRAKE LIGHT BRACKETS
The brake light brackets can be mounted behind the tail light
section of the car body or onto most any vertical or horizontal
surface on the chassis or body.
• To mount the brackets to the tail light section, insert the
screws through holes in the car body and into the screw
openings in the bracket.
• To mount the brackets to the chassis use double-sided
mounting tape, an existing screw hole, or drill two holes at
proper spacing and use enclosed screws.
NOTE: Brake lights will operate when ESC is in the neutral set-
ting or at partial or full brakes. Have fun!
TROUBLE-SHOOTING GUIDE
This section describes possible speed control problems,
causes, and solutions. For additional help, please call for
Technical Assistance.
ESC Will Not Program Properly
• Too little transmitter throw—Increase ATV/EPA setting.
• Make sure ESC is plugged into the throttle channel of re-
ceiver. Check throttle channel operation with a servo.
• ESC SET button not held long enough—Press and hold SET
button until status LED turns solid red.
ESC Over-Heats And Slows Down
• Excessive current to motor—Use a milder motor or a
smaller pinion gear. Do not use motors with fewer than 12
turns.
• Use ESC Cooling Fan as mentioned in Duster II Accessories.
Loss of Throttle Control
• Speed control affected by excessive vibration or a hard im-
pact—Isolate speed control from shock and vibrations with
mounting tape, as recommended in Step 3.
• Re-program speed control
Steering Channel Works But Motor Will Not Run
If status LED is solid RED at all throttle positions:
• No signal from receiver—Make sure speed control is
plugged into throttle channel of receiver. Check throttle
channel operation with a servo. Check the wiring color
sequence of receiver harness.
If status LED is RED at neutral/GREEN at full throttle:
• Check motor connections. Check motor and brushes.
Other causes:
• Not programmed—Repeat programming.
• Check wiring and connections—Check operation of sys-
tem without speed control.
Receiver Glitches/Throttle Stutters During Acceleration
• Motor capacitors broken or missing—Refer to Radio
Interference Section
• Receiver or antenna too close to speed control, power
wires, battery, or motor—Refer to STEP 3
• Bad connections—Check wiring and connectors.
• Excessive current to motor—Use a milder motor or a
smaller pinion gear.
ESC Is Melted Or Burnt/ESC Runs With Switch Off
• Internal damage—Refer to Service Procedures
