RASCAL FORTY ARF ASSEMBLY MANUAL
INTRODUCTION:
SIG’s RASCAL FORTY ARF represents the classic good looks
and lines of yesterday’s private aircraft designs with performance
that meets and even exceeds today’s standards. The RASCAL
FORTY is unlike any .40 size high-wing design available and offers
flight characteristics that are equally unusual for such aircraft. The
airplane is not just easy to fly, it’s almost immediately “comfortable”
to most R/C pilots. The look is decidedly from the “Golden Era” of
aviation and yet the RASCAL FORTY ARF looks right at home on
any modern flight line!
The RASCAL FORTY ARF has a lot more going for it than just its
good looks. Its performance is as remarkable as its appearance.
High speed is impressive and low speed is awesome and what
goes on in between is just about as much fun as you can handle.
The RASCAL FORTY could easily fill the role of a trainer and then
be flown as your second airplane. Set the control throws at the
suggested beginning movements, throttle back and learn to fly
with a truly honest, gentle airplane. When you get through basic
training and comfortable with the requisite take-offs, landings, and
basic flight maneuvers, dial-up the control throws a little to enjoy a
very aerobatic airplane. Inside and outside loops, rolls, inverted
flight, snap maneuvers, great spins, and even knife-edge flight are
all in the RASCAL FORTY flight envelope. Landings and take-offs
are just about the smoothest you’ll ever experience, even when
compared to tricycle landing gear equipped aircraft. As the saying
goes, “real pilots fly tail-draggers”.
The RASCAL FORTY 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 totally unique and also offers good visibility and
orientation in the air.
The two-piece wing allows convenient
transportation in the smallest of vehicles.
This assembly manual has been specifically sequenced to get
your RASCAL FORTY 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 RASCAL FORTY ARF requires a standard 4-channel radio
system and five standard servos. We have used and can highly
recommend both the Airtronics™‚ RD-6000 Sport system and the
Hitec™ Flash 4X system.
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 the Airtronics™‚
RD-6000 Sport radio system with Airtronics™‚ #94102 standard
servos.
In addition, you will need two aileron 24” servo lead
extensions and an aileron servo Y-harness for connection to the
receiver.
ENGINE SELECTION:
Engine choices for the RASCAL FORTY ARF are many. Keep in
mind that the airplane has been designed to be light, producing a
very favorable wing loading.
The design is also relatively
aerodynamically clean.
These two factors result in great
performance when using the recommended engine sizes. Over-
powering this model is totally unnecessary and not at all
recommended.
We’ve found that the RASCAL FORTY ARF really comes into
its own when flown with 4-stroke engines in the .40 - .52
displacement range. We’ve test flown the RASCAL FORTY with
virtually every available 4-stroke engine in this range with
outstanding results. The airplane just seems to fly wonderfully with
4-stroke engines. It just looks and sounds “right” with a 4-stroke in
the nose.
2-stroke engines also fly this airplane very nicely.
Any plain-
bearing or bearing equipped .36, .40, or .46 sport engine would be
a good choice. For example, a great choice would be the Irvine .40
engine. Like all Irvine engines, the .40 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.
COVERING MATERIAL:
Your RASCAL FORTY 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
