Novak GTS BASIC SET UP GUIDE

Be sure to mount the GTS where its power wires are away from other electronics, and will not interfere with any moving parts.
Mount GTS to the vehicle’s chassis with the included double-sided
• tape (use two layers of other double-sided tapes for adequate damping).
• Mount Power Capacitor to chassis with double-sided tape or tie­wrap
Cap becomes dented/damaged, ESC failure can occur--replace immediately.
• Mount the ON/OFF switch in a position where it will be easy to access. You can use a 4-40 or smaller screw to mount the ON/ OFF switch to a hole in the chassis, or use the included double­sided tape to mount the switch in the vehicle
• 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).

For proper ESC operation, adjust transmitter as follows: A. Set HIGH ATV or EPA to maximum setting.
[amount of throw at full throttle]
B. Set LOW ATV, EPA, or ATL to maximum setting.
[amount of throw at full brakes]
C. Set EXPONENTIAL to zero setting. [throttle channel linearity] D.
Set THROTTLE CHANNEL REV. SWITCH to either position.
E. Set THROTTLE CHANNEL TRIM to middle setting.
[adjusts neutral position/increases or decreases coast brakes]
F. Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 70%
throttle and 30% brake throw (or 7:3). [older radios only]
[adjusts trigger throw electronic/digital pistol-grip transmitters]
G. Set MECHANICAL TRIGGER THROW ADJUSTMENT to position
with 2/3 throttle and 1/3 brake throw.
[adjusts trigger throw on mechanical/analog pistol-grip transmitters]

1. MOTOR CAPACITORS
Electric motors generate RF noise that causes interference. included 0.1µF (50V) non-polarized, ceramic capacitors 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 built-in capacitors, install external ones.
Solder 0.1µF (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. INSTALLING OPTIONAL SCHOTTKY DIODE
The GTS has a built-in Schottky diode and should not require an external one under standard conditions. The external Schottky
will optimize the ESC’s braking and motor performance in racing applications with heavy or repeated braking (lap after lap), or when using low-turn modified motors.

To get the best possible performance from your GTS, it is essential that you make very good connections between the battery, speed control, & motor. A common cause of perfomance problems & ESC failures is poor solder joints
skills, we suggest seeking assistance at your local hobby shop or track.
• 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.
• Airflow through the ESC’s heat sink is a huge performance plus. Like a real car, cooling is everything--if you can mount the ESC where it will see some air flow, it will run cooler; and that means that the ESC will be even more efficient (and make you faster!).
Once you’ve decided where to put the GTS in the vehicle, it’s time for some wiring. The GTS uses a high-performance 3-wire system where
the battery & motor share the same red wire. You can direct solder your system for the least amount of resistance

Battery & motor connectors can be used for making your connections. If you are going to use connectors for your battery and/or motor, we suggest the Dean’s Ultra Connectors--do not use crimp on types.
When using battery and motor connectors, please note the following:
• If you have any doubts about your soldering skills, seek assistance from your local hobby shop or track, or see our website for tips.
• Use connectors that cannot be plugged in backwards--reverse voltage will damage the GTS 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 GTS’s battery lead and a female on the GTS’s motor lead to prevent cross connection

The GTS comes with factory-installed power Capacitor that drops ESC operating temperatures by 10-15°F (remember, cooler means your GTS will be more efficient & faster) and dissipates noise & voltage spikes from the ESC’s high switching speed that gives the GTS its smooth throttle response.
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.

When replacing the battery or motor power wires at the GTS’s solder tabs, it’s important to not overheat PCB (printed ciruit board) with the soldering iron by applying prolonged or excessive heating.
• Remove wires from the tab by first removing GTS from vehicle to access solder joints on the bottom of the tabs. Use a soldering iron to apply heat to the wire’s solder joint while gently pulling on the wire to remove it from the hole in the PC Board.
• Replace the wires by stripping 1/8-1/4” of insulation from the end of the new wire. Tightly twist the wire strands and lightly tin with solder. Insert the wire end into the proper hole in the PC Board
there is still solder in the hole you can melt it with the iron while pushing the wire through the hole). Apply heat to the section of wire that is sticking
through the tab’s hole, and add solder to the tip of the soldering iron and to the wire. Add just enough solder to form a clean &
continuous joint from the plated area of the solder tab up onto the wire. Use side cutters to trim excess wire above tab
