INTRODUCTION

Thank you for choosing Global's RCM Trainer 40 ARF and welcome to the exciting world of R/C modeling!
Whether you have built and flown other R/C airplanes in the past or this is your first, you will appreciate the
high quality, very easy assembly and excellent flight characteristics of the RCM Trainer 40 ARF.

The RCM Trainer 40 ARF was designed by expert modelers to be one of the very best trainer airplanes
available today. It features a constant cord wing with a flat bottom airfoil for superior slow flight handling and
forgiving flight characteristics. The long tail moment and large tail surfaces help the airplane fly very smooth
and stable throughout the entire speed range. Tricycle landing gear makes take offs and landings a breeze, too.
This combination makes the RCM Trainer 40 ARF the best flying trainer airplane at any flying field.

When you open up the box, you will notice there is little to do or to purchase to finish your new airplane.
Unlike other trainer kits, the RCM Trainer 40 ARF is a complete kit. Wheels, fuel tank, pushrods, clevises and
spinner are all included. The airframe is completely built and covered by master craftsmen, who take their time
to ensure that every part is straight and properly glued. But what really sets the RCM Trainer 40 ARF apart
from other ARF trainers in its price range is the amount of assembly that's done for you. The RCM Trainer 40
ARF does not require any glue to assemble. The wing bolts together, then bolts onto the fuselage. The horizontal
and vertical stabilizers bolt on. All of the pilot holes for the screws and control horns are already drilled for you.
Even the fuel tank stopper is assembled.

We hope you enjoy your new Global RCM Trainer 40 ARF as much as we have enjoyed designing and
building it for you. If you have any questions or comments, please feel free to contact us. We have also
included a product survey in the back of this manual. Please take the time to fill it out and send it to us. We
would enjoy hearing any comments or suggestions you may have.

This instruction manual is designed to guide you through the entire final assembly process of your new
RCM Trainer 40 ARF in the least amount of time possible. Along the way you'll learn how to properly
assemble your new airplane and also learn many tips that will help you in the future. We have listed some
of our recommendations below. Please read through them before going any further.

✔ Please read through each step before starting
assembly. You should find the layout very com­plete and simple. Our goal is to guide you through
assembly without any of the headaches and hassles
you might expect.

✔ There are check boxes next to each step. After
you complete a step, check off the box. This will
help to keep you from losing your place.

✔ Cover your work table with brown paper or a
soft cloth, both to protect the table and to protect
the individual parts.

If you should find a part missing or damaged, or have any questions about assembly , please contact us at the
address below:

✔ Keep a couple of small bowls or jars handy to
put the small parts in after you open the accessory
bags.

✔ We have included a glossary of terms begin­ning on page # 32. Check it out if you come across
a term that is unfamiliar to you.

✔ We're all excited to get a new airplane in the
air, but take your time. This will ensure that you
build a straight, strong and great flying airplane.

✔ If you come across this symbol
that this is an important point or an assembly hint.

OUR RECOMMENDATIONS

The following section describes our recommendations to help you decide which types of accessories to pur­chase for your new RCM Trainer 40 ARF. We have tested all of these items with the airplane and found that
these will offer the best in performance, reliability and economy.

RADIO SYSTEM

The RCM Trainer 40 ARF requires a minimum 4 chan­nel radio control system that includes four standard size
servos. The radio system we recommend using is the
Hitec Focus 4 FM radio from Hitec. This particular ra­dio system includes the transmitter, receiver, four
standard servos, rechargeable transmitter and receiver
battery packs, a standard wall charger, switch, servo
mounting hardware and a setup guide. It is priced right
and can be used in other airplanes as you advance.

ENGINE

Focus 4 FM

The RCM Trainer 40 ARF requires a .40 to .46 size
two stroke engine. The engine we recommend is the
Magnum XL .40ARNV with remote needle valve. This
engine is a perfect match to the RCM Trainer, both in
power and in ease of installation. The holes that are
predrilled in the motor mount are spaced to fit the
Magnum engine perfectly. The rear mounted needle
valve assembly makes tuning the engine easy and safe.

FIELD SUPPORT EQUIPMENT

Most people getting into R/C worry most about buying the correct accessories for their airplane (radio, engine,
etc.), and that is important. But a lot of people don't put as much effort into the field support equipment they
choose. Field support equipment is a necessary and important part of flying R/C airplanes. Without it, how do
you fuel your airplane, start the engine and do maintenance? Having the proper field support equipment is just
as important as having the correct engine and radio system. Below we detail two types of field support setups.
One is the bare minimum that will be required. The second setup will cost a little bit more, but if you're planning
on staying in the hobby, it's the best way to go in the long run.

MINIMUM SETUP

Magnum Hand Crank Fuel Pump - This is a hand­operated fuel pump that makes filling the fuel tank easy
and hassle-free.

P/N 237365

P/N 237438

Sullivan Chicken Stick - Instead of using your fingers
to flip the propeller and start your engine, you use this
rubber stick. It prevents cuts and scratches to your fin­gers. This is a must-have item for hand-starting your
engine.

Magnum Glow Starter - This cordless glow starter is
used to heat up the engine's glow plug for starting. It
includes a built-in meter that tells you your glow plug's
status. A battery charger is included to charge the unit
after use. You can start your airplane's engine right on
the flight line with this one if you need to.

A NOTE ABOUT COVERING

The covering material used on the RCM Trainer is a
heat shrink polyester material. Because of this, it is
possible with heat and humidity changes that the cov­ering on your airplane may wrinkle or sag. This trait
is inherent in all types of heat shrink material. To
remove the wrinkles you will need to purchase, or bor­row from a fellow modeler, a heat iron. If you need to
purchase one, the Global Sealing Iron # 360900 is
recommended.

Follow these simple steps to remove the wrinkles:

❑ 1) Plug in and turn on the sealing iron to the
medium temperature setting. Allow the iron to heat
up for approximately 5 - 7 minutes.

❑ 2) After the iron has reached temperature,
lightly apply the iron to the wrinkled section of the
covering. Move the iron slowly over the wrinkled
section until the covering tightens and the wrinkles
disappear. You will notice that the color of the cov­ering will darken when it is heated. When the
covering cools back down, it will return to its normal
color.

❑ 1) Looking at the root rib of each wing half,
notice one wing half has two aluminum dihedral
braces preglued into it, and the opposite wing half
has two precut slots in it that the dihedral braces slide
into. See photo # 1 below.

Photo # 1

❑ 2) Align the two dihedral braces with the two
slots and gently push the two wing halves together.

See photo # 2 below.

Photo # 2

If any color smears from any of the seams, the

☛

temperature of the iron is too hot. Turn the tempera­ture dial down and wait about 5 minutes for the iron
to adjust to the lower temperature. If any colors do
smear you can remove the excess using a paper towel
soaked with a small amount of Acetone.

JOINING THE WING HALVES

The control surfaces on the RCM Trainer are

☛

hinged using "EZ" type hinges and glued in place
using C/A adhesive. Because of this, the control sur­faces may be stiff. T o loosen them, gently move each
control surface five or ten times to free them up.

❑ 3) Push the two wing halves together until both
root ribs are firmly pressed against each other. When
properly joined there should be very few , or no gaps
at all, in the center section joint.

The fit of the two dihedral braces in the precut

☛

slots is tight. This is normal. It helps make a very
strong center section joint.

❑ 4) Locate the two 3mm x 16mm machine
screws.

❑ 5) Turn the wing upside down on your work
table. While holding the two wing halves together
firmly, carefully thread the two machine screws into
the two predrilled holes in the bottom of the wing.

Two threaded metal inserts have been prein-

☛

stalled into the wing's surface to thread the machine
screws into.
