Your SpaceWalker ARF is not a toy, but rather a
sophisticated, working model that functions very much like
a full size airplane. Because of its realistic performance, the 
SpaceWalker ARF, if not assembled and operated correctly, 
could possibly cause injury to yourself or spectators and
damage property.

To make your R/C modeling experience totally enjoyable,
we recommend that you get experienced, knowledgeable
help from an instructor with assembly and during your first
flights. You’ll learn faster and avoid risking your model
before you’re truly ready to solo. Your local hobby shop has
information about flying clubs in your area whose
membership includes qualified instructors.

You can also contact the national Academy of Model
Aeronautics (AMA), which has more than 2,500 chartered
clubs across the country. Through any one of them,
instructor training programs and insured newcomer training
are available. Contact the AMA at the address or toll-free

If you have been looking for a way to 

WOW

them at the

field without a lot of work, you have just found it. The Great
Planes SpaceWalker ARF is a balsa, built-up, semi-scale,
1/4 scale airplane that assembles in only a few hours and
is easy on the budget. It does not require any special
building or flying skills. With its thick airfoil and light wing
loading, the SpaceWalker is great for a day of relaxed
flying. What more can we say? Impress your flying buddies
and maximize your fun for minimal cost and time!

The Great Planes SpaceWalker ARF combines the design
expertise and high quality standards of all Great Planes kits
with state-of-the-art ARF technology - for craftsmanship and
performance superior to all other pre-built models.
However, 

this is not a beginner’s airplane!

While the

SpaceWalker ARF is easy to assemble, we must discourage
you from selecting this kit as your first R/C airplane. It is
highly maneuverable, and lacks the self-recovery
characteristics of a good 

basic trainer

such as the Great

Planes 

PT

Series airplanes. On the other hand, if you are

confident with your flying skills and can safely handle
aileron airplanes, the SpaceWalker ARF is an excellent choice. 

1. 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.

2. Take time to build straight, true and strong.
