4. You must properly install the R/C radio system and other
components so that the model operates properly on the
ground and in the air.

5. You must test the operation of the model before every
flight to insure that all equipment is operating and you must
make certain that the model has remained structurally
sound. Be sure to check clevises or other connectors often
and replace them if they show signs of wear or fatigue.

Remember: Take your time and follow directions to end
up with a well-built model that is straight and true.
Please inspect all parts carefully before starting to build!
If any parts are missing, broken or defective, or if you
have any questions about building or flying this
airplane, please call us at (217) 398-8970. If you are
calling for replacement parts, please reference the part
numbers and the kit identification number (stamped on
the end of the carton) and have them ready when calling.

PREPARATIONS

Engine Selection

There are several engines that will work well in your
Extra 300 ARF. We recommend a hot 2-stroke such as an
O.S.

®

.46FX or SuperTigre

G45. If you prefer a 4-stroke,

an O.S. FS-70 is the ticket. Your choice of 2-stroke or
4-stroke will determine the location of the throttle servo
and throttle pushrod exit on the firewall, so plan ahead.

DECISIONS YOU MUST MAKE

Note: We, as the kit manufacturer, provide you with a
top quality kit and great instructions, but ultimately the
quality of your finished model depends on how you build
it; therefore, we cannot in any way guarantee
the performance of your completed model, and no
representations are expressed or implied as to the
performance or safety of your completed model.
