Congratulations on your choice of this kit for your
next project. If you are new to radio control

modeling, we would like to take a minute to give

you some background on the Wanderer.

The 72" version of the Wanderer was developed by
Mark Smith as a first-time building and flying

project. Since its introduction in 1975, over 85,000
kits have been produced. Over the years the

Wanderer has been updated with many changes

recommended to us by first-time builders. The

Wanderer still has the same basic aerodynamics as
the original kit, but has been simplified to make
assembly quicker and easier.

At Dynaflite we take pride in offering kits that are

simple and straightforward to build and provide

value for your modeling dollar.

To make your R/C modeling experience totally
enjoyable, we recommend that you get assistance
with your first flights from an experienced,

knowledgeable modeler. You'll learn faster and

avoid risk to 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. We
recommend you join the AMA, which will provide

you with insurance coverage at AMA club sites and

events. AMA Membership is required at chartered
club fields where qualified flight instructors are
available. Contact the AMA at the address or toll-
