Things You Should Know
Helicopters require a SIGNIFICANT TIME COMMITMENT to learn to fly
R/C helicopters are not dynamically stable, and they require constant stick
input. It is very similar
to balancing a marble on a sheet of glass by radio control. In addition to this,
the glass can
be rotated which then rotates all the directions.
Therefore, it takes a lot of time to develop a good sense of balance and
orientation. You will
learn much faster if you can dedicate at least a half-hour a day to practicing
on a flight simulator.
In addition, helicopters require significant amounts of time to build and
isolate/fix various problems
like vibration, tail wag, and other problems that will develop.
If you like building and tinkering with things for hours, and enjoy the
challenge and satisfaction
of learning difficult skills, then this is a great hobby for you.
If you do not like building and tinkering with things for hours and are easily
frustrated by learning
difficult skills, then you may want to consider another hobby.
Repairs are expensive
Helicopters crash, and they are somewhat expensive to fix.
Some helicopters are more durable than others, and some are much cheaper to fix
- these are
good trainers. But, you cannot expect to learn to fly without spending some
money for repairs.
Be sure to allocate some money for repairs.
Hovering is difficult to learn
Eventually, something will "click" inside your head, and you will "get it". For
some people, this
occurs all of a sudden and everything makes sense. For other people it seems to
be a more
gradual process.
Basically, helicopters suck horribly. Then you get your first hover, and it's
an incredible head rush, and you're
psyched for a whole week, and you're
hooked.
The following guideline should give you enough
information on where to begin and what to get as far as entering the exciting
and challenging hobby of remote control helicopter.
WHAT SHOULD YOU CONSIDER WHEN BUYING for YOUR first RC
helicopter?
Price
Electric or Gas powered helicopter
Just getting into RC Helicopter? Not sure if you should
go Micro , Midsize, Electric or Nitro (Gas)? We usually recommend that beginners
start with Micro fixed pitch electric as they are quiet, easier to fly, and easy
to maintain. With electric you do not need to deal with engines that need to be
broken in and can randomly cut out, fuel lines which get clogged or neighbours
that think it's too loud. You do not need to lug around fuel or starters and
there is no idle/carb/leaner/richer adjustments to worry about. Your hands stay
clean of exhaust/fuel and your neighbours will thank you!
A common misconception is that no electric can stick up
to a nitro. Well with the growing popularity of RC helicopter, there are many
new innovations such as Lithium batteries and Brushless motors that keep
electric and nitro neck and neck. Electric Helicopters are now achieving even
longer flight time than nitro's ( excess of 30 minutes ) and with the right
combination of lithium batteries and the right brushless motor you will have
more power than you can handle!
With Micro Electric FP Helicopter, $120 will get you
start in this great hobby, as for 30 size Nitro Helicopter, you are looking at
spending over $1000 to be ready to fly
Size
Size is very important, because larger helis are more stable and easier to
hover. They have
more inertia, so they move slower and they give more warning of their intent.
Micro helis are
more difficult to hover because they are very skittish and wander off in a new
direction with
very little warning of their intent. Larger helis are not any easier to fly,
though.
Generally speaking Larger the size, easier to fly
Micro/mini:
Dragonfly 4 (FP, RTF-Ready-To-Fly)
Dragonfly 76C (CP, RTF)
Slightly larger: Dragonfly 35 (CP, RTF)
Dragonfly 36 (CP, RTF)
Dragonfly 60 (CP, eCCPM, RTF), can be flown in
backyard/park
Counter rotating:
Dragonfly 5#4 (Counter blades,
RTF) , can be flown in office building or living room at home
Collective pitch vs. Fixed pitch
Fixed pitch (FP) helicopter blades have blades that
remain at a fixed angle (you can not alter their pitch). To get lift on these
helicopters you must increase the power to the main blades. They are simpler in
design, they are easier to fix when damaged, they are easier to set up and they
are cheaper.
Collective pitch (CP) helicopters control lift through
the angle of the blades, they have 3 servos instead of 2 (like the fixed pitch
models) allowing you to alter blade pitch. This result in a more agile machine
but it also means they are harder to repair and are more suited to an
experienced flyer.
Beginners should start with a Fixed Pitch (FP) machine.
With a Fixed Pitch the angle of the main blades remains constant and the flyer
can control altitude by using the speed of the main motor (Revolutions Per
Minute/RPM) allowing for a more calm Heli which will sustain MUCH less damage
after a crash. Fixed pitch machines are also safer and easier to setup and fix.
In a collective Pitch Heli (CP) the RPM is somewhat
constant and the Flyer controls altitude using the angle of the main blades (
more or less angle ) produces more or less lift, thus allowing for a much
faster agile machine which requires much more of an experienced Flyer
Flying conditions required
Indoor or Outdoor Rotor/Motor noise level, Can you fly
it in your backyard or local park?
Where will you be flying?
Indoors : Stay in the Micro Electric range like Dragonfly 4 and Dragonfly 76C
Collective Pitch Micro Heli. these are good size for indoors , can
withstand a few crashes, also be flown outdoors and won't cost you too much.
Outdoors: Most of the micro heli can be flown outdoors as well but are more
affected by the weather ( wind ) due to their small size. A good beginner
outdoor electric chopper is the Walkera 36, one of the most durable and best
selling helicopter out there. Something a little bigger is the Walkera 56, known
for its high quality and extreme capabilities. If you are looking for something
that is ready to fly right out of the box that would be: One last thing: Wind conditions; the bigger the helicopter the more wind
it can cope with, and a collective pitch (CP) helicopter can handle windier
conditions as well (more power, stiffer rotor head).
Upgradeability
Better motor and Blades, Metal frame, etc
A
brushless motor is inherently
more reliable than a brush motor. They, of course, have no brushes to wear out,
so they have a longer life and less downtime due to brush replacement. Because
of the lack of brushes, there is no brush arcing or brush bounce. With no brush
resistance, they typically provide higher speeds (RPM) than brush motors. And
because the winding is typically on the outside element, they offer better heat
dissipation.
The absence of brushes also makes the motor a more quiet (both acoustically
and electrically) unit than one with brushes.
Spare parts
Cost of the spare parts and availability of replacement
parts.
The reason for this is: when you are learning to hover, you will crash. This is
a given. Everyone
crashes. When you crash, you do not want to spend a fortune repairing the
helicopter, because
everyone has limited funds. When you crash, you do not want to wait forever for
replacement
parts, because every day you spend waiting for a part is a day you are not
flying the
helicopter, and learning something.
see the
spares section for detailed prices. The basic
formula is the cheaper the helicopter the cheaper the spares, and the lighter
the helicopter the less crash damage you will incur. and also availability of
spare part locally for quick repair turn around time.
Dragonfly 4 is so small and hard wearing (G10 materials)
meaning you will hardly ever have to buy spares (almost true), reducing your
costs!
Brands/RTF
is it ready to fly or does it need to be built.
Brands; there is nothing really to say about this if you
know what your looking for then we
A Ready To Fly (RTF) helicopter comes 99% assembled and
requires no extras such as electronics or transmitter, if the helicopter has not
got an RTF beside it then you may have to buy extras such as electronics and
radio which gives you greater flexibility but with added expense.
The Dragon Fly 4 is a robust beginner’s machine which
comes with everything a beginner would need including our added training kit and
Free Simulator CD/cable. And if you are Looking for an inexpensive ready to fly
Heli ? Well, the Dragon Fly is the one for you.
What about a flight sim?
A must for any beginner helicopter pilot,. The Dragonfly
4 and Collective Pitch 76C comes with FMS flight simulator
