2 PIT WIZARD INSTRUCTION MANUAL
INTRODUCTION
When designing an electronic speed control, the Novak engineers
are put to the task of setting design parameters such as how wide
the Deadband should be, what percentage of Full Drive should be
applied with the first pulse of transmitter information, or what
Brake and Drive Frequencies to use. In the past, our engineers would
determine the best possible compromise for these parameters
based on different vehicles and driving styles. While these fixed
designs were perfect for some applications and some drivers, they
were not right for others. It became clear that a speed control was
needed that allowed the driver to modify several of the design
parameters to fit their differing applications and needs.
During testing, our engineers found that different vehicles required
different parameter values, just as each individual driver required
different parameters to obtain the type of feel that they desired.
With this criteria in mind, Novak Electronics proudly brings you
the Cyclone Programmable Speed Control (Part #1765) and the
Pit Wizard Hand-Held Programmer (Part #1035).
WHAT’S INCLUDED
• PIT WIZARD
Comes complete and ready to program your Cyclone speed
control right at the track where you need it most. Just add
batteries, connect the D•LINK to speed control, and program.
Also comes with sample Profiles to start you on the right track.
• PROFILE SOFTWARE
The same customized profiling software that comes with the
Novak DataLink is already inside the Pit Wizard. Allowing you
to customize the adjustable parameters of the Novak Cyclone
Electronic Speed Control, including Deadband width, Minimum
Drive percentage, Drive & Brake PWM Frequencies, and more.

ADJUSTABLE PARAMETERS
The Pit Wizard’s Profile Software accesses the Cyclone speed
control’ s previously hidden fourth Profile. The user-programmable
fourth Profile gives you the ability to customize several design
parameters of the speed control. This adjustability will allow you
to custom tailor the speed control’s response and feel to your
preference for different applications. This section lists the user-
adjustable parameters, their descriptions, and applications:
• NEUTRAL
–Measured in microseconds (µs).
–Position at which the speed control is at rest, with no Drive or
Brake being applied.
–Initial value is taken from the transmitter, as recorded in the
One-Touch Set-Up memory of the speed control.
• FULL THROTTLE
–Measured in microseconds (µs).
–Trigger position at which speed control reaches Full Drive.
–Initial value is taken from the transmitter, as recorded in the
One-Touch Set-Up memory of the speed control.
• FULL BRAKE
–Measured in microseconds (µs).
–Trigger position at which speed control reaches Full Brake.
–Initial value is taken from the transmitter, as recorded in the
One-Touch Set-Up memory of the speed control.

ADJUSTABLE PARAMETERS (CONT.)
• DEADBAND
–Measured as percentage (%) of Full Throttle trigger position.
–Space between Minimum Brake and Minimum Drive, with
Neutral located at the center of this space (Figure 2).
–Changing the Deadband value will change the point at which
forward Drive begins with respect to Neutral.
–Increasing Deadband will require more trigger movement away
from Neutral to reach both the first pulse of Drive and the first
pulse of Brake. Example: Adding 10% to the value of Deadband
will in turn add 5% Deadband in the Full Throttle trigger
direction, and 5% Deadband in the Full Brake trigger dir ection.
–Decreasing Deadband will require less trigger movement to
reach the first pulses of Drive and Brake.

6 PIT WIZARD INSTRUCTION MANUAL
ADJUSTABLE PARAMETERS (CONT.)
• DRIVE PWM FREQUENCY
–Measured in Hertz (Hz).
–Frequency at which the duty cycle information is being sent
from speed control to motor (How many times per second
the motor is being cycled on and off to control it’s speed).
–Drive PWM Frequency controls acceleration characteristics of
your vehicle with respect to trigger movement in the Full
Throttle direction (Figure 3). By changing the value of Drive
PWM Frequency you change the manner in which the vehicle
responds to transmitter trigger input.
–Increasing Drive PWM Frequency requires more initial trigger
movement to obtain the same given speed. Light vehicles feel
more controllable / Heavy vehicle more sluggish.
–Decreasing Drive PWM Frequency requires less initial trigger
movement to obtain the same given speed. Light vehicles are
harder to control at the low end (possibly spinning the rear
wheels) / Heavy vehicles are more reactive.
–
This parameter can be used as a valuable tuning asset for
different types of motors and track conditions.

7 PIT WIZARD INSTRUCTION MANUAL
ADJUSTABLE PARAMETERS (CONT.)
• MINIMUM DRIVE
–Measured as percentage (%) of the Drive value.
–Amount of Drive applied with the first pulse of transmitter
throttle information (Figure 4).
–Increasing the Minimum Drive will make the speed control
begin at a greater percentage of Full Drive. This is useful for
tracks with good traction and for heavier vehicles to eliminate
‘dead’ trigger movement before the motor can actually move
the vehicle (and will increase the vehicle’ s minimum rolling speed).
–Decreasing the Minimum Drive will make the speed control
start at a smaller percentage of Full Drive. This is useful for
tracks with low-bite and lighter vehicles where lower initial
power will give more controllability. This parameter is also a
valuable tuning asset for different types of motors.

8 PIT WIZARD INSTRUCTION MANUAL
ADJUSTABLE PARAMETERS (CONT.)
• BRAKE PWM FREQUENCY
–Measured in Hertz (Hz).
–Frequency at which the duty cycle information is being sent
from speed control to motor for braking.
–Brake PWM Frequency controls deceleration characteristics of
your vehicle with respect to trigger movement in the Full Brake
direction (Figure 5). Changing Brake PWM Frequency allows
you to change the manner in which the vehicle responds to
brake trigger input.
–Increasing the Brake PWM Frequency will require more initial
trigger movement to obtain a given amount of braking. Light
vehicles brake more controllably under initial braking / Heavy
vehicles brake less reactively.
–Decreasing the Brake PWM Frequency will require less initial
trigger movement to obtain a given amount of braking. Light
vehicles are harder to control under initial braking (possibly
locking up the wheels) / Heavier vehicle are more reactive to
initial braking efforts.

9 PIT WIZARD INSTRUCTION MANUAL
ADJUSTABLE PARAMETERS (CONT.)
• DRAG BRAKE VALUE
–Measured as percentage (%) of Full Brake value.
–Adjusts amount of Drag Brake applied within the Deadband
when throttle trigger is in the Neutral position (Figure 6).
–When the Drag Brake value is greater than zero, Drag Braking
is applied in the Deadband area. When the throttle trigger is
returned to Neutral, braking information is sent to the motor .
This can be used to obtain Drag Brakes without shifting the
Neutral position of the transmitter with the throttle trim, and
will in turn eliminate the Deadband (now ‘dead’ trigger) space
that has also been shifted toward the Full Throttle side of the
trigger movement before Drive can be applied.
–When the Drag Brake Toggle is set to ON position, the Brake
Pot on the Cyclone adjusts the Drag Brake V alue. Drag Brakes
during Neutral/Deadband are now set at the same level as
Minimum Brake. With Drag Brake Toggle ON, the Drag Brake
V alue can NOT be set with the Pit Wizard, only with the Brake
Pot on the Cyclone.
–When Drag Brake T oggle is OFF, the Brake Pot on the Cyclone
adjusts only the Minimum Brake value. Drag Brake Value can
now be set above zero with the Pit Wizard to obtain Drag
Brakes. Minimum Brake value can now be independently set
higher or lower than the Drag Braking (Figure 8).
