Locating Switches, Wires and Connectors
Take a moment to familiarize yourself with the controller’s wires, switches and connector.
The front side (shown in Figure 1) contains the buttons and display needed to operate and
monitor the controller. The 15-pin connector provides the connection to the R/C or micro-
computer, as well as connections to optional switches and sensors.
At the back of the controller (shown in the figure below) are located all the wires that must
