INTRODUCTION

The Great Planes 1/4-Scale Patty Wagstaff Extra 300S ARF
is a versatile airplane designed for giant-scale aerobatics. The
Extra 300S ARF is capable of wild, 3D aerobatics while still
keeping the slow speed and landing performance of a low
wing sport model. The Extra 300S ARF is an airplane that
will go where you point it without any surprises.
For the latest technical updates or manual corrections to the
Extra 300S ARF, visit the web site listed below and select
the Extra 300S 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.

The Extra 300S ARF is an excellent sport-scale model and
is eligible to fly in IMAA events. The IMAA (International
Miniature Aircraft Association) is an organization that
promotes non-competitive flying of giant-scale models. If
you plan to attend an IMAA event, contact the IMAA for a
copy of the IMAA Safety Code at the address or telephone
number below.

Scale Competition
Though the Extra 300S is an ARF and may not have the
same level of detail as an "all-out" scratch-built competition
model, it is a scale model none-the-less and is therefore
eligible to compete in the Fun Scale class in AMA
competition (we receive many favorable reports of Great
Planes ARFs in scale competition!) In Fun Scale, the
"builder of the model" rule does not apply. To receive the five
points for scale documentation, the only proof required that
a full-size aircraft of this type in this paint/markings scheme
did exist is a single sheet such as a kit box cover from a
plastic model, a photo, or a profile painting, etc. If the photo
is in black and white, other written documentation of color
must be provided. Contact the AMA for a rule book with full
details.
