Decisions You Must Make; Radio Equipment; Engine Recommendations; Additional Items Required - GREAT PLANES RV-4 Instruction Manual

We, as the kit manufacturer, provide you with a top
quality kit and instructions, but ultimately the quality and
flyability 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.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
Before starting to build, compare the parts in this kit with
the Parts List and note any missing parts. Also inspect
all parts to make sure they are of acceptable quality. 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, or e-mail us at
productsupport@greatplanes.com. If you are contacting
us for replacement parts, please be sure to provide the
full kit name RV-4 and the part numbers as listed in the
Parts List.
For the latest RV-4 updates, you can also check our web
site at www.greatplanes.com.
If you have not flown this type of model before, we
recommend that you get the assistance of an experienced
pilot in your R/C club for your first flights. If you're not a
member of a club, your local hobby shop has information
about clubs in your area whose membership includes
experienced pilots.
In addition to joining an R/C club, we strongly recommend you
join the AMA (Academy of Model Aeronautics). AMA
membership is required to fly at AMA sanctioned clubs. There
are over 2,500 AMA chartered clubs across the country.
Among other benefits, the AMA provides insurance to its
members who fly at sanctioned sites and events. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. Contact the AMA at
the address or toll-free phone number below:

DECISIONS YOU MUST MAKE

This is a list of items required to finish the RV-4 that must be
purchased separately. For some of these items there is more
than one option which will require a bit of decision making
ahead of time. Order numbers (in parentheses) are provided
for your convenience.

Radio Equipment

A quality five channel (if you do not plan on flaps you can use
a four channel radio) or greater radio system. Seven servos
with an output of at least 40 ounce-inches (five servos if you
omit the flap option). Two - 12" servo extensions (HCAM2100)
for the ailerons, four - 6" servo extensions (HCAM2000) for
the flaps and receiver and two "Y" connectors (HCAM250) for
the flaps and ailerons.

Engine Recommendations

There are several engines that will work well in the RV-4. Our
official engine size recommendation range is .40 to .52 two
-stroke or .52 to .70 four-stroke. Engines such as the O.S.
.40 FX (OSMG0540), O.S. .46 FX (OSMG0546), O.S. FS-52
(OSMG0852), O.S. FS-70 (OSMG0870), Super Tigre
GS.40 (SUPG0125), GS .45 ABC (SUPG0150) and the
G-.51 (SUPG0154) are all excellent choices for the RV-4. If
you select an engine in the upper end of the size range,
remember that this is supposed to be a scale model that is
intended to fly at scale-like speeds, so prudent throttle
management should be practiced.
