Mechanical Specifications

This section details the mechanical characteristics of the AX500 controller.

Mechanical Dimensions

The AX500 is delivered as an assembled and tested Printed Circuit Board. The board includes connectors for direct connection to the Optical Encoders and to the Radio, Joy- stick or microcomputer on one side. On the other side can be found Fast-on tabs for high- current connection to the batteries and motors. A heat sink is mounted beneath the board to help with the heat dissipation of the Power Transistors
