FOUR-STAR 60 ARF ASSEMBLY MANUAL
INTRODUCTION:
SIG’s FOUR-STAR 60 ARF combines the classic looks and
performance of Sig’s Four-Star series in an almost ready to fly
package. The FOUR-STAR 60 ARF is easy to fly and makes an
ideal choice for your first low wing airplane. Intermediate and
advanced flyers will love the maneuverability and smooth handling
of the Four-Star 60 ARF, making it the sport model you'll want to
take to the flying field every time.
Set the control throws at the suggested low rates for your first
flights, throttle back and enjoy a truly honest, gentle airplane. As
your skill level advances, dial-up the control throws a little to enjoy
a very aerobatic airplane. Inside and outside loops, rolls, inverted
flight, and snap maneuvers are all in the FOUR-STAR 60 flight
envelope.
The FOUR-STAR 60 ARF kit has been engineered to get you into
the air quickly as possible with an R/C model that will truly last.
The airframe has been expertly built and covered with AeroKote
™
.
This material is both rugged and easy to repair. The covering trim
scheme is provided on three large peel & stick mylar decal sheets.
This assembly manual has been specifically sequenced to get
your FOUR-STAR 60 ARF assembled and into the air very quickly.
We strongly suggest that you read through the manual first to get
familiar with the various parts and their assembly sequences. The
proper assembly and flying of this aircraft is your responsibility. If
you are new to the sport/hobby of radio control, we urge you to
seek the assistance of a qualified person to help you assemble this
model airplane. If you do not understand a particular assembly
step or sequence, do not guess - find qualified help and use it.
RADIO EQUIPMENT:
The FOUR-STAR 60 ARF requires a standard 4-channel radio
system and five standard servos. We have used and can highly
recommend both the Hitec
™
and Airtronics
®
systems. Both of
these very affordable and reliable radio systems offer all the
features you’ll need for this and the many other R/C aircraft in your
future. For reference, this assembly manual shows the installation
of a Hitec
™
radio system with standard servos. In addition, you will
need two aileron 12” servo lead extensions and a 6” aileron servo
Y-harness for connection to the receiver.
ENGINE SELECTION:
Engine choices for the FOUR-STAR 60 ARF are many. The
FOUR-STAR 60 ARF has been designed to produce excellent
performance when using the recommended engine sizes. Do not
use an engine larger than recommended.
2-stroke engines are a perfect choice to power your FOUR-STAR
60 ARF. Any plain-bearing or bearing equipped .60 to .75 sport
engine would be a good choice. For example, a great choice
would be the Irvine .61 engine. Like all Irvine engines, the .61 is
powerful, reliable, and quiet. Whatever engine you choose, take
the time to carefully break it in according to the manufacturer’s
instructions. A good running, reliable engine is a minimum
requirement for the enjoyment of this or any R/C model aircraft.
The FOUR-STAR 60 ARF can also use a variety of 4-stroke
engines. Any 4-stroke engine in the .65 - .90 displacement range
should provide plenty of power. An important thing to remember is
that typical 4-stroke engines have their throttle arms usually
located differently than throttle arms on 2-stroke engines. If you
want to power this model with a 4-stroke engine, you will likely
have to install a new, relocated throttle cable tube. While this is not
difficult, it is something to consider when choosing an engine.
COVERING MATERIAL:
Your FOUR-STAR 60 ARF has been professionally covered using
AeroKote
™
. This material is well known for its ease of application,
light weight, and consistency of color. If you live in a dry climate,
you may notice that some wrinkles might develop after removing
the covered parts from their plastic bags. This is perfectly normal
in low humidity climates. Your model was built and covered in a
part of the world with relatively high humidity and therefore the
wood was likely carrying a fair amount of moisture. When exposed
to drier air, the wood typically loses this moisture, dimensionally
“shrinking” in the process. In turn, this may cause some wrinkles.
However, wrinkles are easy to remove by just using a hobby type
heat iron.
