The E Performance Series YAK 54 EP 3D ARF is the
second release in a line of electric, built-up, all out
performance 3D planes. Just like Reactor EP, the YAK 54 EP
3D ARF can perform virtually any aerobatic maneuver with
authority. High-capacity LiPo battery packs will allow you the
convenience of electric flying, combined with the flight
characteristics of planes much larger in size, like the Great
Planes YAK 54 1.60 ARF. In addition to the flight
performance of a large 3D plane in a small package, the
beautiful trim scheme from the YAK 54 1.60 ARF has been
carried down to the YAK 54 EP 3D ARF.
For the latest technical updates or manual corrections to the
YAK 54 EP 3D ARF visit the Great Planes web site at
www.greatplanes.com. Open the “Airplanes” link, then
select the YAK 54 EP 3D 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.
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 fly at
AMA clubs. Though joining the AMA provides many benefits,
one of the primary reasons to join is liability protection.
Coverage is not limited to flying at contests or on the club
field. It even applies to flying 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
flying near full-scale aircraft and avoid flying near or over
groups of people.
1. Your YAK 54 EP 3D ARF 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 YAK 54 EP 3D ARF, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.
2. You must assemble the model according to the
instructions. Do not alter or modify the model, as doing so
may result in an unsafe or unflyable model. In a few cases
the instructions may differ slightly from the photos. In those
instances the written instructions should be considered
as correct.
