	Quick Start

This section will give you the basic information needed to quickly install, setup and run your AX3500 controller in a minimal configuration.

What you will need

For a minimal installation, gather the following components:

•One AX3500 Controller and its provided cables

•12V to 40V high capacity, high current battery

•One or two brushed DC motors

•One R/C to DB15 connector (provided)

•Miscellaneous wires, connectors, fuses and switch

Locating the Switches and Connectors

Take a moment to familiarize yourself with the controller’s switches and connec- tors.
