The Super Duty XR is epuipped with the industry standard receiver
input connector on a user-replaceable input harness that
works with
all the major radio brand’s new receivers
. However, some very old
receivers must have the wiring sequence inside the plastic 3-pin
connector housing changed.
This is an important step, because the
receiver electronics may be damaged if the sequence is not correct.

JR, Hitec, Futaba, new KO, & Airtronics Z receivers do not need input
harness re-wiring.
Airtronics Z receivers have blue plastic cases & new
KO cases have tabs on the input harness openings as in
Figure 1
.
• Plug the connector on one end of the input harness into the receiver
with the
BLACK wire toward the outside edge
of receiver case.
• Plug the other end of the input harness into 3-pin header inside
rectangular opening on top of the Super Duty XR’s case with the
WHITE wire toward the ‘S’ (signal) marking
on the ESC’s label.

If you have an older KO or Sanwa/Airtronics, you must change the
sequence of the ESC’s input harness wires--Old Sanwa/Airtronics cases
are black color & Old KO cases do not have tab openings, as in
Figure 2
above.
• Using a small standard/flat blade screwdriver,
remove the red and
black wires
from the plastic connector housing at the receiver end
of the input harness as in
Figure 3
below.
•
Interchange the red and black wires
in the plastic 3-pin connector
housing at the receiver end of the input harness.
• Insert modified end of the harness into the receiver with the
RED
wire toward the outside edge
of receiver case.

1. MOTOR CAPACITORS
Electric motors generate RF noise that causes interference. The
included 0.1
µ
F (50V) non-polarized, ceramic capacitors must be
used on all motors to reduce motor noise & prevent ESC damage.
Note: Some motors come with capacitors built-in. If
your motor only has two capacitors, you need to install
a capacitor between the positive & negative motor tabs.
If you experience radio inter-ference when using only
the built-in capacitors, install external ones.
Solder 0.1
µ
F (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (–) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (–) motor tab & GROUND tab*.
*If motor has no ground tab (below), solder the capacitors to motor can.

2.
DO NOT USE SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible speed
controls. Using a Schottky diode will damage the speed
control and void the product’s warranty.
3. USE NEUTRALLY TIMED MOTORS
Using motors with other than 0
°
timing will draw excessive
current in reverse, and result in speed control overheating and
premature motor wear.
Modified motors (with adjustable end bells) are recommended,
and should be timed to 0
°
for optimum performance.
You should not use stock motors that are used for racing (with
fixed end bells) as these motors usually have very high timing
and run very poorly in reverse.
Johnson or Mabuchi motors that
come with car kits are not timed as aggressively and also work
well--these motors usually last longer also.

wiring speed control, motor, & battery
The Super duty XR is very powerful, and capable of very efficient
delivery of battery power to the vehicle’s motor. Therefore, good
connections must be made between the battery, speed control, and
motor. A common cause of perfomance problems & ESC failures is
poor connections--If you have any doubts about your soldering skill,
we suggest seeking assistance at your hobby shop or track.
general installation note
general installation notes
s
::
• Keep the ESC and its power wires away from other electronics
in the vehicle, especially the receiver & antenna.
• Do not bundle receiver/signal wires with other wires--messy
installations account for nearly all radio interference (glitching)
problems. A clean looking install almost always works better.
• Route ESC wires to clear any moving parts in the vehicle.
Once you’ve mounted the Super Duty XR, it’s time for some wiring.
The Super Duty XR is wired for two battery packs, and is equipped
with high-power versions of JST/Tamiya-style battery connectors so
you can use standard sport battery packs.
Using different style connectors will be discussed at the end of this section.
1. BATTERY PACK CONNECTIONS
The Super Duty XR is designed to be used with two battery packs. However,
it can also be used with one standard R/C battery pack (6 or 7 cells @
1.2VDC/cell) or with one 12 volt DC battery. Using the Super Duty with a
single battery requires special wiring and is discussed in this step.

USING A SINGLE BATTERY WITH VOLTAGE ABOVE 8.4VDC
When using a single 12VDC battery (like lead acid or a gell cell), there
is limited output from the B.E.C. circuit. A separate receiver battery
pack can be used for improved servo/receiver performance.

If you are going to use connectors for your motor, or change the factory
installed battery connectors, we suggest the Dean’s Ultra Connectors.
When installing battery & motor connectors, please note the following:
• If you have any doubts about your soldering skills, seek assistance
from your hobby shop or track, or see our website for tips.
• Use connectors that cannot be plugged in backwards--reverse
voltage will damage the Super Duty XR and void the warranty.
• Use a female connector on battery packs to avoid shorting.
• If using connectors for both battery & motor leads, use a male
connector on the battery leads and a female on the motor lead to
prevent cross connection (also voids warranty).
For additional information on connector usage, visit our website.

MOUNTiNG ESC
Mount ESC where its power wires will be away from other electronics
and won’t interfere with moving parts. If possible, select a location
that allows airflow through the heat sinks--
If the ESC gets some air flow,
it will run cooler; and that means it will be more efficient, and you’ll go faster!
For single battery pack use, proceed to STEP 3 & 4 before completing STEP 2
• Mount Super Duty XR in the vehicle with the included double-
sided tape
(in the Traxxas E-Maxx, use the stock mounting screws)
.
• Mount Power Capacitor to chassis with double-sided tape or tie-wrap.
If Power Cap. becomes dented/damaged, ESC failure can occur
--replace
immediately.
Longer Power Capacitor wires decrease performance
.
• Install the ON/OFF switch using a screw or double-sided tape
where it will be easy to access.
• Be sure receiver & antenna are mounted as far from ESC, power
wires, battery, and servo as possible--these components all emit
RF noise when throttle is being applied. On graphite or aluminum
chassis vehicles, it may help to place receiver on edge with crystal
& antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top
of antenna mast (cutting or coiling excess antenna wire will reduce radio range).

The Super Duty XR comes with the best available power Capacitor
that drops ESC operating temperatures by 10-15
°
F (remember, cooler
means your ESC will be more efficient & faster) and dissipates noise &
voltage spikes from the speed control’s high switching speed.
You MUST use Novak Power Capacitors--other capacitors with similar
ratings don’t provide the same protection. We’ve done extensive research
to find capacitors with the very best quality factors.
