INTRODUCTION

In 1989 the very successful Great Planes Ultra Sport .40 kit
was introduced. Many modelers learned to fl y aerobatics
with this plane. We are proud to bring you the great fl ying
Ultra Sport .46/EP in the ARF version. It has been updated
to use an electric motor or a glow engine. Unlike the kit, the
ARF version will have you enjoying the smooth aerobatic
performance in just a few hours.
For the latest technical updates or manual corrections to the
Ultra Sport .46/EP visit the Great Planes web site at www.
greatplanes.com. Open the "Airplanes" link, then select Ultra
Sport .46/EP. If there is new technical information or changes
to this model a "tech notice" box will appear on the page.

IMPORTANT!!! Two of the most important things you can
do to preserve the radio controlled aircraft hobby are to
avoid fl ying near full-scale aircraft and avoid fl ying near or
over groups of people.
FAA INFO
As a new owner of an unmanned aircraft system (UAS), you
are required to place your FAA number on or in your plane. It
is your responsibility to operate this vehicle safely following
the FAA rules. Please contact your local authorities to fi nd
out the latest rules and regulations.
Follow These Important Safety Precautions
1. Your Ultra Sport .46/EP should not be considered a toy, but
rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Ultra Sport .46/EP, if not assembled and
operated correctly, could possibly cause injury to yourself
or spectators and damage to property.
