After
practicing on the simulator, find your self reasonable size room, in this room
you should have all doors closed as any wind can affect the movement of the
dragonfly, turn off the air-condition or heating.
With the
training kit bolt on:
Step
l
First check that all the controls are correct. We suggest you loosen off the two
screws of the electric motor and slide it away so that the pinion gear from the
motor is no longer engaged to the main gear. Now turn your transmitter on
followed by plugging in the helicopter. Centre all trims and pull the throttle
stick down to the bottom. Please note at this stage that you might have to
adjust the throttle trim so in this position, the electric motor is not turning.
Next
check the swash plate is level. To adjust this, use the trims on your
transmitter for forward and aft and left and right cyclic.
Once
you have achieved all these initial settings, unplug the helicopter from its
battery and turn the transmitter off. Re-engage the electric motor and make sure
that you do not make the gear mesh too tight between the pinion gears and the
main drive gear. To achieve this slide through a piece of paper between the two
gears so there is slightly backslash.
In
the appropriate room which is quite large and with no obstacles, place the
models in the middle, turn the transmitter on and plug in the flight battery and
wait until the LED light is activated. Then test that the servos operate
properly but please remember do not apply any throttle. Keep the throttle stick
at the off position.
If
everything is working correctly, position yourself at least 2 metres behind the
helicopter and slightly off to one side. Please be sure that you are able to see
the nose of the helicopter.
Please note when flying that you always watch the nose of the helicopter. If the
nose of the helicopter twists to the left, you are then required to give right
tail rotor to correct this (for example when using Mode I type radio, you push
the left hand stick to the right). Watch the nose and slightly apply enough
throttle until the model becomes light on its skids.
All
helicopters exhibit a small amount of unavoidable drift on takeoff due to the
side thrust of the tail rotor and also the turbulence coming from the main rotor
blades which is called "rotor wash". This is mainly noticed as drift to the left
just before takeoff. Therefore it is possible that the machine will tend to yaw
its nose to the left or right when a small amount of power is applied, then
straighten up when more power is applied to give authority to the model.
Observe whether or not the helicopters tips forward or backwards. If it tips
forward, you will need to apply elevator trim towards the rear. This is reversed
if it tips the other way. Do this until there is no more detectable forward or
backwards or even sideward tendencies.
Always when applying the throttle, please apply it softly. Too much throttle
will make the helicopter climb too quickly and you may have difficulties in
correcting it quickly enough.
Step 2
First
flights should be what are called "bunny hops". This is initially applying a
slight amount of power to get the machine light on its skids.
Once this
has happened, apply more power to lift the machine so it is approximately 30
centimeters off the ground. Watch for any change of direction of the model. If
you cannot correct it immediately, decrease the throttle and land.
This is
the initial technique to learn to fly. You must do this until you believe you
are starting to put in the right correction commands to keep the helicopter in
one spot. How many times and how many batteries you will achieve this in will
depend on your ability to become familiar with the feeling and feedback from the
model.
At the
preferred height of 30 centimeters which we find is best for flight training,
always make sure you watch the nose of your helicopter not the tail. Keep
practicing and you will find that your flights will become longer.
Also
please note that depending on the size of your room, after a few minutes the air
circulating around the room can cause some turbulence created by the model. If
you find this is off-putting, we suggest that you land and let the air settle.
Please
remember that model helicopters no matter what type will never stay still. They
will always require some form of input to stop the drift or the tendency to
turn. This is not a sign of something faulty with the helicopter, but more the
nature.
As you
become more familiar with your helicopter, you will find that your hand and eye
co?ordination will enable input to correct the movement of the helicopter as
soon as it starts, and this will start to show smooth flight.
Step 3
Once you
believe you are now familiar with the basic hovering of your helicopter, you
should now start experimenting with turning the helicopter slightly to the left
or right using the tail rotor (yaw).
Please
note always remember if you have turned your helicopter to the left, if you get
into any trouble, yaw the helicopter back to the right so you have the tail
pointing at you for easier reference. We suggest that you turn the model some 45
degrees towards you always remembering to watch the nose.
Takeoffs
are a little easier than landing. This is due to the ground effect turbulence of
the rotor blades. However spot landing at a modest rate of descent is not as
difficult as it might seem. As you become more proficient with your helicopter
finding a larger hall so you can start to fly around more or even on dead calm
days, by going outside you can achieve some forward flying circuits. If you do
fly outside, please remember any wind will affect the performance of the humming
bird. Please keep this in mind and do not get surprised if it suddenly climbs or
drops without you making any input. This can be caused by a slight breeze or
even a thermal wind coming through.
Remember
practice makes perfect and even we suggest buying a computer flight simulator
can greatly enhance and speed up the learning technique. In addition a simulator
is great for teaching you "nose in". This is when the nose of the helicopter is
pointing at you which, once this is done, some of the inputs are reversed which
can catch out the novice pilot.
Please
keep in mind once you notice that the performance of the helicopter is dropping,
this is a sign that the flight pack is going flat. We suggest that you
immediately land and recharge your battery.
Remember
the proper environment of no wind and a large space without obstacles is the key
to learning.
