Designed with the same ultra-powerful surface mount technology as the World Champion GTX programmable racing ESC (electronic speed control), the Micro GT will get the most performance from your 1/18th or 1/24th scale vehicle. The Micro GT is capable of handling 4-7 cells and any sub540 size motors that are used in 1/18th & 1/24th scale Micro R/C cars, and comes loaded with all the standard features found in Novak's award winning line-up of ESCs: Novak's One-Touch Set-Up is the original & still the easiest way to program your ESC to your transmitter. [. . . ] · DISCONNECT BATTERIES WHEN NOT IN USE Always disconnect battery from ESC when unattended or not in use to avoid possible short circuits. Even if switch is off, MOSFETs may fail & cause shorting of battery pack that could result in fire or burning of ESC & surrounding objects. · TURN TRANSMITTER ON FIRST Turn on transmitter before ESC so you will have control of the radio equipment. · INSULATE WIRES Always insulate exposed wiring with heat shrink tubing or electrical tape to avoid short circuits.

Set HIGH ATV or EPA to maximum setting. [Amount of throw at full throttle] 1. CHECK MOTOR CAPACITOR INSTALLATION Electric motors generate radio noise that can interfere with your receiver and cause radio problems. Three 0. 1µF (50V) non-polarized, ceramic capacitors are included and must be installed on every motor to help reduce the noise generated by the motor and to prevent ESC damage. If your motor does not have all 3 capacitors shown below, they must be added (0. 1µF capacitors are also available in Novak kit #5620). 0. 1µF (50V) capacitors should be soldered between: · POSITIVE (+) motor tab & NEGATIVE (-) motor tab. · POSITIVE (+) motor tab & GROUND (motor can). · NEGATIVE (-) motor tab & GROUND (motor can).
