INTRODUCTION

The full scale Extra 300SP is the choice of many airshow 

performers. The Extra 300SP is known for its tremendous 
power and ability to perform all-out aerobatics. Great Planes 
has taken the best qualities of the full scale aircraft and reduced 
it down to a lightweight, 50" electric powered ARF.

For the latest technical updates or manual corrections to 
the “Extra 300SP” visit the Great Planes web site at www.
greatplanes.com. Open the “Airplanes” link, and then select 
the “Extra 300SP” 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.

Academy of Model Aeronautics

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 fl y at AMA clubs. 

Though joining the AMA provides many benefi ts, one of the 

primary reasons to join is liability protection. Coverage is not 
limited to fl ying at contests or on the club fi eld. It even applies 
to fl ying 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:

Academy of Model Aeronautics

5151 East Memorial Drive
Muncie, IN 47302-9252

Tele. (800) 435-9262

Fax (765) 741-0057

Or via the Internet at: http://www.modelaircraft.org

IMPORTANT!!!

 

Two of the most important things you can 

do to preserve the radio controlled aircraft hobby are to avoid 
fl ying near full-scale aircraft and avoid fl ying near or over 
groups of people.

SAFETY PRECAUTIONS

Protect Your Model, Yourself & Others…

Follow These Important Safety Precautions

1. Your “Extra 300SP EP” 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 “Extra 300SP EP,” if not assembled and 
operated correctly, could possibly cause injury to yourself or 
spectators and damage to property.
