Introduction
Thank you for purchasing the XR3i 3-channel radio system.
This system has been designed to provide R/C racers with a
high quality, user-friendly radio system that can be relied
upon year after year, race after race. The XR3i's grip dial
accessible auxiliary third channel is ideal for use as a
mixture channel in gas boats or as a transmission shifter for
vehicles such as the Traxxas
®
T-Maxx. It is important that
you carefully read this manual before attempting to operate
your XR3i system.
For your convenience, a blank data sheet has been included
in the back of this manual. Once you have input all the
necessary data for a particular model into your transmitter,
we strongly recommend that you immediately write that
information down on the data sheet provided. This will
insure that in the rare case of a memory failure, you will not
lose the models' setup data.
For those who would like to get out to the track quickly
with just the basic radio setup, please refer to the Quick Start
section that follows.
