you can try your
hand at on one of the R/C flying simulators available as
software for your PC. See our "Great
Starter Planes" section for help
in choosing
your first model.
- Find an
instructor.
With an instructor, you'll learn faster and with more confidence
than if you start out solo. If your instructor's radio has a trainer
system, you
can buy a compatible
radio, connect the two, and fly with less risk to your plane. To
find an instructor, check with hobbyist friends. Check the phone
book for flying clubs. Attend fun fly events (announced in
newspapers and free circulars) and ask around.
And consult
the Academy of Model Aeronautics (AMA) by calling :
1-317-287-1256,
writing 5151 East Memorial Drive, Muncie, IN 47302, or visiting
their website at
www.modelaircraft.org. Ask for the locations of clubs near you.
- Pick your
power. Traditionally, R/C planes have been powered by 2-stroke engines
that burn a methanol/nitro-methane/oil mixture called "glow
fuel." But there are
other power
sources to consider: 4-stroke engines and clean, quiet electric
motors.
A few things to think about.
How much does it cost?
A lot depends
on your budget. You can spend as little as $100 or as much as $1,000
on the basic equipment. Average cost for a complete (but no frills)
beginner package runs around $200-$350.
How fast does a model go?
Trainers usually
cruise at 25-30 mph and can land at speeds as slow as 12-15 mph. However,
there are also unmodified, off-the-shelf airplanes that can deliver
speeds of up to 200 mph!
How far can a model fly?
The range for
a modern R/C system is about a mile. But to maintain control, you
need to have your model close enough to tell what it is doing. Even
a plane with a 5-6 foot wingspan looks tiny at half a mile.
What happens if I run out of fuel in flight?
Contrary to popular
belief, you have control even if your engine stops running. You just
glide your plane in for a "dead stick" landing. The radio
system has its own batteries for power.
After reviewing
the "Flying Basics" below, you should have a good idea of
the design characteristics you will want in your first plane. Tower
Hobbies offers many trainer models from numerous reputable manufacturers.
Our own
Tower Hobbies Trainer 40 ARF actually guarantees that you will
learn to fly successfully. After practicing the basics of flying and
gaining some confidence "behind the sticks," you will want
to explore the many other exciting
styles of R/C aircraft.
Flying Basics
Aerodynamics: To
fly, an airplane's wing has to overcome gravity by developing lift
greater than the weight of the plane. Since it can't do that standing
still, airplanes use thrust...force directed backwards...to drive
the wing forward through the air and generate lift. However, thrust
has its own opposition to overcome in the form of drag—the resistance
of the air to a body moving through it. If lift and thrust are greater
than gravity and drag, you have the potential for flight...and fun.
Wing Location: Wing
placement, for the most part, falls into two major categories—high
wing design and low wing design. In a high wing design, the weight
of the model is suspended below the wing. When the model tilts, the
model's weight tries to return it to a level position. As a result,
high-wing models tend to be more stable, easier to fly—and natural
choices for trainers. A low-wing model is just the opposite. With
its weight above the wing, it tends to be less stable—excellent for
advanced fliers who want to perform rolls, loops and other aerobatic
maneuvers.
Airfoil: If
you face the wing tip of the plane and cut it from front to back,
the cross section exposed would be the wing's airfoil. The Flat-Bottom
Airfoil will develop the most lift at low speeds and helps return
the model to upright when tilted. This is ideal for trainers and first-time
pilots. A Symmetrical Airfoil's top and bottom have the same shape,
allowing it to produce lift equally whether right side up or upside
down and to transition between the two smoothly. This is recommended
for advanced pilots. Lastly, a Semi-Symmetrical Airfoil is a combination
of the other two and favored by intermediate and sport pilots.
Wing Area/Wing Loading: Wing
area is the amount of wing surface available to create lift. Wing
loading is the weight that a given area of the wing has to lift and
is usually measured in ounces per square foot. Generally, a light
wing loading is best for beginners. The plane will perform better
and be easier to control.
Dihedral:
Dihedral is the upward angle of the wings from the fuselage.Dihedral
increases stability and decreases aerobatic ability.
Wing Thickness: Wing
thickness — measured from top to bottom — determines how much drag
is created. A thick wing creates more drag, causing slower speeds
and gentler stalls and is ideal for beginners. A thin wing permits
higher speeds and sudden stalls — desirable for racing and certain
aerobatic maneuvers.
Landing Gear Location: Tricycle
gear includes a nose gear and two wing (main) gears, making takeoffs
and landings easier—ideal for beginners.
Kits vs. Prebuilts
Until recently, most R/C airplane models came in Kit
form—consisting of a box full of parts, a set of plans, an instruction
manual and some hardware. And kits remain very popular. Many modelers
enjoy the challenge of putting them together as much as actually flying
them. Depending on the kit, however, assembly can take weeks or even
months to complete, and also requires a well-equipped hobby toolbox.
For a number
of reasons—including a shortage of leisure time—hobbyists are now
turning to "prebuilt" models as another way to enjoy R/C
flight. Actually, prebuilt planes are great for first-time pilots.
Because they come factory-assembled, you KNOW they're constructed
well. Many are put together with materials as high in quality as any
kit. Because you haven't put your heart and soul into building them,
you're less likely to be nervous when flying them. And they let you
focus on learning to fly, without also having to learn new model building
skills.
You can choose
from models with varying degrees of preassembly. The following acronyms
are commonly used to identify types of prebuilt planes:
ARF:
Stands for "Almost
Ready-to-Fly." Most can be completed and flight-ready with as
little as 16-20 hours of assembly. Major structures such as the wing
halves, fuselage, and tail fins all come entirely built and covered.
You simply assemble those sections, install your power plant and radio
gear, attach the landing gear and a few other pieces of hardware...and
you're done.
RTF:
Stands for "Ready-to-Fly."
Want a model that's ready for the air as little as 20 minutes after
you open the box? Get an RTF. You'll still have to complete a few
final assembly steps, but far less than even ARFs require. True RTFs,
like the
Hobbico SuperStar 40 Select, also include engine and radio gear
already mounted inside the model. There's no easier way to get airborne!
Choosing the Size of Your Plane
The "size"
of a model plane generally refers to the size of engine, in cubic
inch displacement, required to fly it successfully. The most popular
sizes are 20 (requiring a .20-.36 engine), 40 (.40-.53 engine) and
60 (.60-.75 engine). Many other sizes are available, too, ranging
from small, .049-powered craft up to massive, giant-scale models.
Most trainers
fall into the 40-size category. That's because 40s are fairly stable,
with enough heft to fly well in breezy conditions, but still small
enough to be affordable for new hobbyists. Many 60-size trainers are
also available, and offer the advantage of even greater stability—plus
easier visibility once aloft—both due to their larger dimension.
Choosing
Your Type of Plane
What first attracts
many would-be pilots to the idea of R/C flying is the thought of controlling
a blistering-fast ducted fan jet or wicked WWII warbird. And there's
no better way to put a quick END to your flying career than to start
with such a model They're simply not designed for anyone who hasn't
yet developed sharp piloting skills. Model plane
styles are available that duplicate virtually every kind of full-size
aircraft. The best ones for the first-timers are, without question,
trainers and trainer-like sailplanes. These are specifically engineered
to fly slowly and smoothly. They'll keep you out of trouble—giving
you time to acquire the skill and confidence You'll need for those
jets and warbirds.

the different plane types that are available.
Engines
Model planes can
use several different types of power sources. Electric models carry
battery-powered motors to turn the propeller. Gliders or sailplanes
ride on thermal air currents (some also have electric motors for quick
launching to great heights). Most R/C models, however, are powered
by glow engines.
The most economical
are basic 2-stroke engines with brass bushings supporting the crankshaft.
For a little more power, you might choose a 2-stroke that uses ball
bearings to support the crankshaft. The ball bearings also extend
the life of the engine, so you can continue using it to power future
models. The cost, however, is nearly twice that of a bushing-equipped
engine.
Finally, there's
the 4-stroke glow engine—slightly less powerful than 2-strokes of
the same size and higher priced, but offering more torque, swinging
bigger props, using less fuel and sounding much more realistic.
Radios
R/C planes are
controlled by a
radio system that consists of a transmitter—which stays with you
on the ground—plus a receiver, servos, and receiver battery (all of
which are "on-board" components, mounted inside your model).
Most aircraft radio systems come with everything you need, including
a rechargeable battery pack.
As mentioned
earlier, first-time pilots should always seek the help of an instructor.
And an important part of working with an instructor is making sure
that both of you use radios with "trainer system" or "buddy
box" capability. The trainer system allows you to connect your
radio to your instructor's, using a cable. You'll still be the one
controlling your model, so long as your instructor holds down the
trainer switch on his transmitter. But if you start having trouble,
all the instructor has to do is release the switch to take over full
control.
Most trainer
planes require a radio with at least four channels of control, to
operate the throttle, elevator, rudder and ailerons. But not all 4-channel
radio systems come equipped with the necessary four servos. Make sure
your system has as many as your plane requires.
One "ideal"
first 4-channel radio is the Tower 4FM Combo with 4 standard servos.
Not only does it have trainer system capability, but it's also an
FM system—which reduces the potential for radio interference compared
to AM radios.
Tools & Building Equipment
Regardless of
whether a model comes in kit form or prebuilt, some
building tools and workshop accessories will be needed to make
it flight-ready. These include such common items as a hobby knife,
T-pins, screwdrivers, pliers, sandpaper, masking tape, and perhaps
a drill. Building a kit also takes some specialized equipment like
covering tools. Follow the Accessories Required links for the plane
you choose to see a list of the tools needed.
R/C model building
adhesives are also required, and differ from the white glue and model
airplane cement you may have worked with in the past. Cyanoacrylates
are commonly used. These are glues specially formulated for working
with wood, which provide a range of curing speeds—giving you as little
or as much time as each assembly step requires. "Thick"
cyanoacrylates also help to fill slight gaps between parts.
Modeling Epoxies
are two-part adhesives, consisting of a resin and a hardener. At steps
where very strong bonds are critical, a plane's manual will often
recommend epoxy. The resin and hardener must first be mixed, then
applied to the surface—so mixing cups, mixing sticks and inexpensive,
disposable epoxy brushes also come in handy.
Accessories
When you buy a
model airplane, you'll probably also need to buy a number of additional,
inexpensive accessory items to make it flight-ready (those items are
listed under the Accessories Required links for the plane you choose).
These parts are traditionally left out of kits because the appropriate
sizes depend on your choice of engine; also, experienced hobbyists
may have a brand preference or already keep those parts in their workshop.
Required accessories often include the following:
Covering —The
adhesive-backed, plastic or fabric "skin" that surrounds
a model airplane's structure, applied by a process of heating and
stretching.
Pushrods —Rods
that link your radio system's servos to the parts of the model that
those servos move. They're often made of wire or a firm piece of balsa,
fiberglass, or plastic, with a clevis fastener at the end.
Control Horn —A
bracket, mounted on a part of the model, where the pushrods are attached.
Hinges —Connect
the moveable surfaces of a model to the main, static structure.
Foam Rubber —Used
to cushion the on-board radio equipment to protect it from engine
vibration.
Wing Seating Tape —Applied
where the wing fits onto the fuselage, to cushion the wing and prevent
exhaust oils from entering the fuselage.
Wheel Collars —Small
metal collars which keep the plane's wheels positioned correctly on
the axle.
Wheels —Available
in several styles, such as treaded, non-treaded, scale, and air-filled.
Spinner —Plastic
or aluminum cone mounted at the "nose" of the plane to improve
looks and aerodynamics.
Engine Mount —Reinforced
structure, often made of nylon or aluminum, that allows your engine
to be attached securely to the plane.
Fuel Tank, Tubing & Filters —The
sized used depends on the engine you select; therefore, these often
are not included with the model.
Engine Accessories —Propellers
are usually not included with the engine or the plane; also, your
engine may or may not come with a muffler and glow plug.
Field Equipment
Once
your aircraft is chosen, built and covered, there's only one thing
left to do...fly it! To do that, you'll need what we refer to as "flight
line equipment"—such as fuel, a fuel pump, engine starting equipment
and a few other basic tools. Except for the fuel, most flight line
supplies are one-time purchases. You can use them throughout your
modeling career, with as many different models as you fly.
Most modelers
go to the field equipped with the following, all stored in a "flight
box" for easy transport:
Power Panel — the
centralized power source for electrical field equipment
12V Field Battery —to
supply power to the power panel
DC Charger —to
recharge the 12V field battery
Glow Plug Clip —an
electric device that gives your engine's glow plug the initial heat
it needs to burn fuel
Fuel Pump —to
move fuel from your gallon can or jug to the plane's fuel tank, available
in hand-crank or electric-powered styles
Fuel Line, Filters & Cap Fittings —to
connect your fuel to the pump, and the pump to the plane's fuel tank.
12V Electric Starter —a
device for quick, easy engine starting, powered from the power panel
(a small wooden dowel or "chicken stick" can also be used).
Miscellaneous Tools—including
a 4-way glow plug/prop wrench.
Glow plugs and propellers —it's
always a good idea to carry extras...without a spare, you might be
forced to stop flying early.
The
glow fuel used for a model engines carries a percent rating, which
indicates its nitromethane content. For trainer aircraft, 10% or 15%
is recommended. Use a good quality fuel with a blend of castor oil
and synthetic lubricants to protect your engine. Avoid "cheap"
fuels, which sometimes attract moisture and cause engine parts to
rust.
