BUTTERFLY - LIVINGROOM FLYER

THE WORLD’S LIGHTEST READY TO FLY MODEL AIRCRAFT

Congratulations on your purchase of the
Plantraco Butterfly - the Lightest and Smallest
Ready To Fly R/C Model Airplane in the World! 

Get Ready to pilot your Butterfly indoors in your liv-
ingroom, garage, office, or classroom. On dead calm
days, you can also fly outdoors in your backyard, but
the remarkable thing about this radio controlled fly-
ing model is that it can be enjoyed inside, no matter
what the weather is like outside. 

The total flying weight of the Butterfly is about 4
grams, to put that in perspective, this instruction
manual weighs 3 times the weight of the Butterfly!
Hard to believe, but it’s a fact!

This low weight enables you to fly the Butterfly with-
out any fear of damaging the walls. You can fly it
around people so long as they are all paying atten-
tion to the flying model.  Low weight also means
that the Butterfly has a tough time of damaging
itself in a crash most of the time - another advantage
of ultra low weight construction.

These instructions will tell you how to enjoy flying
your Butterfly.  Please note that we have included
several videos on the included CD-ROM disc.  If you
have problems understanding something in the man-
ual, watch the “video instructions” on disc or down-
load from

- IMPORTANT!

Before you pick up the Butterfly model in this case
you should read this manual or you will risk damag-
ing the Butterfly airframe structure!

The Plantraco Butterfly is a Toy for Big Boys.
Small Children can enjoy watching the Butterfly fly
but they should be instructed not to pick it up. Dogs
and Cats are likely to break it too. Be mindful of this.

If you damage your balsa airframe, replacements
are available from the plantraco website.
