INTRODUCTION
In 1946 a group of Lockheed employees, including Tony
LeVier, designed and built three Cosmic Winds. These very
small, single seat racers were designed to compete in the
1947 Goodyear Trophy Race, in Cleveland Ohio. They came
in 3rd and 4th in the Race. However, in 1964 one of the three
planes called the Ballerina did win the Kings Cup Race in
the UK. One of the three original planes is now in the EAA
AirVenture Museum in Oshkosh, Wisconsin. Great Planes
has taken the great looks of the full scale Cosmic Wind and
reduced it down to a light weight, electric powered ARF. The
plane is small enough that it can be placed in the back seat
of most cars but large and quick enough to still enjoy fl ying
at the local fl ying fi eld. So if you are ready to fl y a piece of
racing history, let’s get started building.
For the latest technical updates or manual corrections to the
“Cosmic Wind EP” visit the Great Planes web site at www.
greatplanes.com. Open the “Airplanes” link, then select the
“Cosmic Wind EP” ARF. If there is new technical information
or changes to this model a “tech notice” box will appear in the
upper left corner of the page.
Academy of Model Aeronautics
We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club. The AMA is the governing body of model
aviation and membership is required to fl y at AMA clubs.
Though joining the AMA provides many benefi ts, one of the
primary reasons to join is liability protection. Coverage is not
limited to fl ying at contests or on the club fi eld. It even applies
to fl ying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. There are over 2,500
AMA chartered clubs across the country. Contact the AMA at
the address or toll-free phone number below:

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.
SAFETY PR ECAUTIO NS
PROTECT YOUR MODEL, YOURSELF & OTHERS…
FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS
1. Your “Cosmic Wind 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 “Cosmic Wind EP”, if not assembled and
operated correctly, could possibly cause injury to yourself
or spectators and damage to property.
