[. . . ] VOLTAGE cUt-OFF circuitry When active (see Track Guide to turn ON/OFF), the built-in Novak Smart-Stop Voltage Cut-Off Circuitry lets you safely use 1-2S Lithium Polymer (LiPo) or Lithium Iron Phosphate (LiFe) battery packs by cutting off the speed control's throttle output when the critical safety voltages are reached. The circuitry monitors the pack voltage and automatically selects a 1S or 2S cut-off voltage value [3. 125/6. 25V (1S/2S) LiPo; 2. 375/4. 75V (1S/2S) LiFe]. When the ESC detects that the critical safety voltage value will soon be reached, it begins interrupting, or "blipping, " the throttle output as an early warning that the voltage is getting low and the throttle output will soon be completely shut off. When the critical voltage is reached, the throttle output to the motor gets completely shut down to keep the voltage from dropping further (Red & Green LEDs will alternately flash & you still have steering control).

Built-in LiPo voltage cut-off circuitry. Recommended for 1S (or 4-cell NiMH) racing and 2. 4GHz radio systems. Two each of 9" length black, red, blue, yellow, and orange 14GA wire. 10 pieces in Novak kit #5840, and 100 pieces in Novak kit #5841. Novak heat shrink tubing is 6" long and available in six sizes: 1/16" - 3/8". 6 piece assortment in Novak kit #5850, and 24 piece assortment in Novak kit #5851. Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short circuits, which can damage the ESC. Exposure to CA glue or its fumes can cause damage to internal components of the ESC and result in premature failure. INSULATE WIRES NO CA GLUE P1 step 1­connect input harness The GTB 2 ESC has a userreplaceable input harness with a 2mm mini plug on the ESC end of it and the industrystandard connector on the receiver end of it. The GTB 2 ESC works with all major radio brand's new receivers [Refer to Figure 1 to see how to connect the included user-replaceable input harness]. However, some very old receivers must have the wiring sequence in the plastic 3-pin JST connector housing changed on the receiver end. step 3­Wire ESC to Motor The GTB 2 is compatible with all Novak 540 and 550-sized brushless sensored motors. It is not compatible with brushed or sensorless brushless motors. INSTALL PINION GEAR Tighten pinion's set screw on flat of motor shaft. Adjust the motor position for proper free play. You NEED a small amount of play between the pinion gear and the spur gear (about the thickness of a piece of paper)­check the free play at several positions around the spur gear to ensure a proper mesh (just in case the gears are out of round). STEP 5-one-touch programming With ESC connected to (at least) a receiver and a charged battery pack: 1. PRESS & HOLD ESC'S ONE-TOUCH/SET BUTTON 3. TURN ON THE SPEED CONTROL'S POWER With transmitter throttle at neutral, and still pressing the SET button, slide the ESC's ON/OFF switch to ON position. transmitter adjustments Transmitter adjustments may not be required to properly complete the One-Touch programming of the speed control. [. . . ] Place the BLUE Phase `A' motor wire onto motor's `A' solder tab & solder. Use soldering iron to apply heat to exposed wire; begin adding solder to tip of iron & to wire. Add just enough solder to form a clean & continuous joint from the plated area of solder tab up onto the wire. Solder the ESC's YELLOW Phase `B' motor wire to the motor's `B' solder tab. [. . . ]
