[. . . ] using a receiver battery pack If you are planning to use an external receiver battery pack to power the electronics you need to do the following: 1. Plug the external 5 cell (1. 2VDC/cell) receiver battery pack into the battery slot of the receiver. Leave the ESC's ON/OFF switch in the OFF position, and use receiver battery pack's ON/OFF switch to turn the system power on and off­­Do not use the ESC's switch. trouble-shooting guide Steering Channel Works But Motor Will Not Run · Red & Green status LEDs alternating­­Li-Po Cut-Off Circuitry activated.

An external power capacitor is installed on ESC & MUST be used. Failure to use Capacitor may result in higher temperatures & possible thermal shut-down or damage. Always turn on the power of the transmitter first so that you will have control of the vehicle when you turn it on. With the higher performance of brushless systems, undesirable radio system noise may occur when used with lower quality transmitters (like some RTR radios). The current transmitter that is included in the Losi® Mini Rock CrawlerTM--LSR-3000 DSM Transmitter: MLST2--is acceptable to be used with the Mongoose Crawler.

Always insulate exposed wiring with heat shrink tubing (Novak #5850/#5851) or electrical tape to prevent short circuits, which can damage ESC. Exposure to CA glue or its fumes can cause damage to internal components of the speed control and result in premature failure.

However, some very old receivers must have the wiring sequence in the plastic 3-pin JST connector housing changed on the receiver end. This is important, as the receiver & servo electronics may be damaged if the sequence is incorrect. For example, Airtronics Z receivers have blue plastic cases and new KO cases have tabs on the input harness openings. Old Sanwa/Airtronics cases are black in color and old KO cases do not have tab openings. For instructions on changing the wiring sequence for older receivers, visit the Novak Web site.

Schottky diodes must NOT be used with reversible ESCs (including brushless). Schottky diode usage will damage the ESC & void warranty. The factory-installed Power Capacitor MUST be used with brushless & brushtype motors. If Power Capacitor becomes dented or damaged, ESC failure can occur--replace immediately (Novak #5683). Longer Power Capacitor wires will decrease performance. 1. [. . . ] Make sure that the speed control or the power wires will not interfere with any moving parts in the vehicle. Select a location that has good cooling and allows airflow through heat sinks. If the ESC gets air flow, it will run cooler; and that means it will be more efficient! Note: The Mongoose Crawler is default programmed with Li-Po Cut-Off Circuitry turned ON in all Throttle Profiles. See Custom Programming Sheet to change this setting. Additional Novak 2mm low-loss power connectors available from www. teamnovak. com transmitter adjustments If you have any problems with Step 4, adjust transmitter as follows and then repeat the One-Touch programming in Step 4: ·NOT ALL TRANSMITTERS HAVE THESE ADJUSTMENTS· Proper brushless motor gearing is determined by motor & ESC temperatures during and at the end of the run. Refer to the `PROPER GEAR SELECTION' portion of the CUSTOM PROGRAMMING Sheet (Pg. 5) to determine proper gearing & avoid overheating. Servo plugged into steering ch.
