- DO NOT fly on days of high humidity, such as rain or snow.
Battery and Charger
IMPORTANT NOTES: IMPORTANT NOTES: Lithium batteries such as lithium polymer
(LiPo) and lithium ion (Li-Ion) batteries are much more volatile than
alkaline, NiCd and NiMH batteries, which are also used in RC applications.
Follow all instructions and warnings carefully to avoid damage to property and
/ or injury, as misuse of lithium batteries may result in a fire. By handling,
recharging, or using the supplied lithium batteries, you are taking all risks
associated with lithium batteries. If you do not agree to these terms, please
return your product in a new, unused condition immediately to the place of
purchase. You must read the following safety and warnings before charging or
using the lithium battery.
- Keep the lithium battery away from flammable materials in a safe area.
- Never charge the lithium battery unattended. When charging the battery pack, you should always remain in visual contact to monitor charging and respond immediately to possible problems. Always use a fireproof underground for charging.
- After charging/discharging the battery, allow it to cool to room temperature before recharging. Also, it is NOT necessary or recommended to fully discharge the battery before recharging (lithium batteries do not have any memory and it is safer to charge partially discharged batteries when a suitable charger and appropriate settings are used).
- To charge the battery, use only the charger or a compatible lithium battery charger. Otherwise there is a risk of fire, which can lead to property damage and / or injury. Do not use a NiCd or NiMH charger to charge a lithium battery.
- If the battery starts to bloat at any time during charging or discharging, stop immediately. Disconnect the battery quickly and safely, and place it in a safe, open area, away from combustible materials, to observe it for at least 15 minutes. Charging or discharging a battery that has started to swell may cause a fire. A battery that is already a small amount inflated may not be used.
- Store the battery at room temperature (approx. 20-25 ° C). If the battery is being transported or temporarily stored, the temperature range should be 4-37° C. If possible, do not store the battery or model in a hot location or in direct sunlight. In a hot garage or car storage, the battery can be damaged or even catch fire.
- IMPORTANT NOTE: DO NOT LEAVE THE LIPO BATTERY CONNECTED TO THE ESC UNLESS YOU ARE READY TO FLY. IF THE BATTERY IS LEFT CONNECTED TO THE ESC WHEN IT IS NOT IN USE THE LIPO BATTERY WILL BE OVER-DISCHARGED BY THE SMALL AMOUNT OF CURRENT THE ESC CONSUMES.
- DO NOT STORE THE LITHIUM FLIGHT BATTERY COMPLETEY CHARGED. For more security and longevity of the lithium battery, it is best to store them only partially charged.
- Do not store the lithium battery in the model! Never leave the battery in the model after the flight, but store it in a fire-proof place as described above.
Contents
Setup Instruction
- Install 4 AA batteries (not included) in the transmitter.
- Connect the battery to the receiver, then stick the battery into the compartment with velcro, making sure the battery is well secured.
- The setup is now done. Follow the instructions below to finish adjustment before you start flying the plane.
Centering of the Control Surface
When the transmitter is switched on and the flight battery is connected to the
controller (and installed in the battery box), it is now possible to connect
the control wires to the rudder and treble control surfaces and to center the
surfaces accordingly.
Make sure that the rudder/elevator is properly centered as shown in the picture above/below.If the rudder is angled off to the right or left, adjust the push rod by its arc-shaped section slightly, making sure the rudder is properly centered.If the elevator is angled off to a lower or upper position, adjust the push rod by its arc-shaped section slightly, making sure the rudder is properly centered.
Before Starting
ATTENTION:
This checklist is NOT a substitute for the exact passage of the contents in
this manual! Although it can be used as a quick start guide, we strongly
recommend that you read the instructions carefully before use.
- Always switch on the transmitter first
- Make sure the throttle stick is in the low position before the battery is connected.
- Let the model take off (by hand pushing or lifting off a flat / flat surface)
- Load the model on a flat / flat surface
- Remove the battery from the regulator
- Always switch the transmitter off
Suitable Flying Fields
Due to the size and weight of the model, it is seen as a “Parkflyer”. It is
therefore recommended to fly the model in a park, schoolyard or other area
that is large enough and that no persons or structures are in the way. We
recommend an airfield size of at least one soccer field. The larger the area,
the better, especially when flying is first learned. DO NOT fly on parking
lots or areas where many people are located.We also recommend flying over
lawns, since in the event of a crash less damage will occur on this surface.
Short lawns are better suited to take off or land, as long lawns can cause an
overrun and damage to the model can occur. An ideal airfield provides smooth
surfaces for launch and landing (for example, asap) and lawns to fly over.
Fly on expansive surface without obstacles and bushes. Never fly the airplane close to a motorway, train tracks, power lines, people gathering, flight or residential areas.
Flying Conditions
Fly the model only on calm days without wind, especially when you are still
learning to fly. It is also strongly advised to fly only under quiet
conditions until you are familiar with the controllers and the handling of the
model. Already weak winds can make the learning of flying much more difficult
and carry the aircraft even from your field of view.If you are a beginner, we
recommend allowing a more experienced pilot to fly the model and trim properly
before attempting your first flight. A tested, flyable and properly trimmed
model is much easier and more comfortable to fly! Please contact your local
hobby shop and / or model flying club to find an experienced pilot in your
area.
After properly trimming the aircraft in a quiet environment and being familiar
with the handling/characteristics, you can fly in light winds or experience
and self-assessment at wind speeds of up to 8-11 kilometers per hour.
DO NOT fly on days of high humidity such as rain or snow.
Charging Instructions
To charge the supplied lithium battery, use only the supplied USB charging
cable. Charging the lithium battery with a charger that is not compatible with
lithium batteries (such as a NiCd or NiMH battery charger) or another lithium
battery charger with incorrect settings may damage the battery or even cause
property damage or personal injury to lead. Follow the steps below to charge
the lithium battery with the included charger.
- Always unplug the battery from your plane
- Carefully plug the charging cable into the USB port on your computer or USB adapter.
- Connect the battery to the charging cable.
- The charging process takes about 3.5 hours. For safety reasons, never charge the battery for longer than 4 hours. While charging, the red LED indicator will be flashing. When the charging is finished, the red LED will be off.
Transmitter
Binding Process
Binding is the process by which the receiver is programmed to recognize the
GUID (Global Unique Identifier) code of a particular sender. When a receiver
is connected to a transmitter, the receiver responds only to that one
transmitter.
-
Turn off the transmitter. Throttle the control lever down to the lower position.
CAUTION:
Keep the Gyro switch in the middle or novice position
CAUTION:
Leave the aircraft in a quiet position for the gyro to be calculated. -
Connect the battery to the aircraft and turn on the transmitter within 5 seconds.
-
The receiver LED indicator flashes for about 3-8 seconds to automatically connect.
-
When the receiver LED indicator stops flashing, the connection process is complete.
Follow the steps below if you are using normal use:
- Switch the transmitter first
- Connect the battery with the aircraft
- The LED receiver indicator flashes for a few seconds
- Shift the throttle lever up to Max and then down to Min to unlock
- Now a normal use should be feasible
DANGER:
DO NOT fulfill these steps near persons or other property to avoid injury and
to avoid damage.
CAUTION:
Make sure that the transmitter is first turned on and then connected to the
battery. If you want to switch off the transmitter, make sure that the battery
is first switched off or not connected.To enable easy flying, the Easy Trainer
is supplied with a pre-installed gyro. To turn on the gyro, slide the stick to
the “Anfänger” (Beginner) position. To turn the gyro off, slide the stick
toward the “Experte” (Expert) position. The center position allows a weaker
gyroscopic effect.
ATTENTION:
It is strongly recommended to turn on the gyro during the pilot’s flight,
especially when flown by a beginner. Please note that the aircraft should be
about 5-7 seconds in a quiet environment before the gyro is turned on for the
first time to allow calibration.
Calibration of your Control System
- Move the throttle stick to the minimum position
- Turn on the transmitter and then the receiver
- DO NOT unlock the gas
- Hold the sticks as shown for several seconds
- Once you hear a “beep” sound, it means the remote control system is calibrated based on the horizontal level you hold it on.
Control Surface
Start to Fly
Until you are familiar with your plane, you should not fly if the wind speed
exceeds 16 km / h.Check Before Departure: Always check the correct response to
input from your controller before each flight. Make sure the ailerons,
elevator, and rudder are working properly and that none of the functions have
been reversed by mistake
Hand Start
Until you can efficiently fly your model, you should always be supported by a
second person at hand start. Your helper holds the modelat the bottom of the
fuselage. When both have signaled “ready”, move the throttle lever to full
power. Your helper should take a few steps with the aircraft high above the
head, then throw the model quickly but controllably, either parallel to the
ground or with tip up. At first, the model will still rise gently, but within
a few seconds it will also reach enough speed to climb up high. Move the
elevator to “up” (up) to establish the ascent. Once you have reached a safe
flight speed at a comfortable height (about 15 feet), use the controls as
necessary to make a gentle turn away from the runway.
The Flight
You should keep in mind that when the aircraft flies away from you, you have
to move the aileron stick to the right, so that the aircraft is moving to the
right.When the model flies towards you, move the aileron stick to the right
and the aircraft moves to the left. Of course, the aircraft still responds in
the same way, it is only that your orientation has reversed. This should be
kept in mind while they are learning to fly (and it is also a good reason to
take flight hours from an experienced pilot!).To make a turn, pull the
elevator upwards while you operate the aileron to bring the model into a
transverse position. To stop the turn, move the aileron in the opposite
direction.As soon as you have lifted the aircraft to an appropriate altitude,
your first task will be to trim the model for the straight ahead flight. The
model flies best at about 3/4 gas. Adjust the trims of the transmitter so that
small control surface adjustments can be made as required until the aircraft
flies straight without countersteering. Maybe your helper can adjust the trim
for you.Remember to keep the model high enough to have enough response time
for corrections, but do not fly too far away. Otherwise, it will be difficult
to detect airports and directions.A final check before landing: look at how
the model will react when it’s time to land and you turn off the engine. To do
this, turn off the engine while the aircraft is still in the air. The model
should pass in a gentle, downward glide landing approach. Thus, the model
should react when it is actually time to land. Turn the engine back on and go
back to your original altitude. Try again, this time adding landclasses. Give
gas to get back up, and take the landscaping away again. Practice this climb
and glide a few more times to accurately assess the distance you need to land.
Landing
To land you fly past the wind past the landing area. Now move gently in the
wind direction, guide the landscaping and reduce the throttle so that the
aircraft enters a descending glide path. If necessary, add some gas to extend
the glide path until you reach the runway. When the model approaches and loses
altitude, use the elevator to control the landing approach and altitude.
Continue to change the height until the model touches the ground. At this
time, the height control should be pushed completely or almost completely
forward. This causes the aircraft to slow down and settle on the ground.
Later, if you have more experience with your plane, you can fly with pleasure
and slow flybys with raised landscaping.
WARNING:
If the propeller jams during a rough landing and can not turn, the batteries
and the speed control become very hot when you try to give more gas. Turn the
throttle lever down immediately to stop the engine. If you do not, the engine,
speed control and / or battery will be damaged.
After Flying
Disconnect the battery and remove it from the aircraft. Then turn off the
transmitter. Allow the battery to cool before recharging, or allow the engine
to cool before installing a new battery for the next flight. Check the
aircraft carefully to ensure that nothing is loose or damaged.
One-key Return Instruction
This airplane comes with one-key return function, which enable the plane to
return by the opposite direction that the plane takes off. Follow below steps
to activate the function:
- Place your plane heading to the take-off direction.
- Do NOT unlock the throttle, press the activation button and hold for several seconds until you hear a “beep” sound, the rudder surface will respond, meaning the one-key return function is now activated.
NOTICE:
Every time when you power on the plane, it requires to activate the one-key
return function. To use this function during flight, press the one-key return
switch button. the plane will turn around automatically, back to the opposite
direction where it takes off.To quit, just press again the switch button, or
control any servo stick(rudder/elevator), the plane will back to your control
immediately.
Not matter you flies the plane under manual control or gyro assist mode, when
you turn on the one-key return function, the plane will enter gyro assist mode
automatically to help stable flying back. When you quit this function, the
plane will back to the what the control mode it was.
CAUTION:
This function is bound to the receiver, instead of to the transmitter,
which means the plane will return ONLY to the opposite direction that the
plane takes off. It also means when the plane returns and passes the position
where you activated the function, the one-key return function will NOT return
the plane back to the take-off position.
Disposing of exhausted batteries
The following instructions are addressed to those who use batteries or products with built-in batteries and do not resell them in the delivered condition.
- Exhausted batteries must never be thrown into the household waste! You are legally required to return the exhausted batteries so that a correct disposal can be guaranteed. You can hand them over at local collecting points or directly in the shop. As being a retailer for batteries we are required to take them back. Our take-back obligation for rexhausted batteries is limited to batteries which were/are new batteries of our range. Old batteries of the type named above can therefore be returned to us either sufficiently postage paid or they can be delivered free of charge directly at our dispatch warehouse at the following address: MSG Online GmbH, Wirtschaftspark 9, AT-8530 Deutschlandsberg.
- Meaning of battery symbolsBatteries are characterised with the symbol of a crossed waste bin (see below). This symbol indicates that batteries must not be disposed in the household waste. At batteries which contain more than 0,0005 percent of Quicksilver, more than 0,002 percent Cadmium or more than 0,004 percent lead, the chemical name of the used harmful substance can be found under the waste bin symbol – „Cd“ stands for Cadmium, „Pb“ for Lead and Hg“ for Quicksilver.
- Starter BatteriesThe following special features apply when it comes to buying starter batteries: The seller is acc. § 10 BattG obliges a final deposit of € 7.50 including VAT if the end user does not return the used starter battery to the seller at the time of the purchase of the new starter battery. The customer receives a pawn coupon when purchasing a starter battery. If the old starter battery is returned to a return point set up by the public waste disposal authority, the customer has to confirm the disposal by means of a stamp and a signature. Subsequently, the customer has the possibility to return this confirmation to the seller, with the identification of his customer number for the refund of the deposit. Alternatively, the customer can also hand over his old starter battery together with the Pfandschein to the reimbursement of the deposit directly at the seller. (Due to the Dangerous Goods Ordinance the dispatch of the old battery to the seller is not permitted.)
Disposal
General
Dispose of the product at the end of its service life in accordance with
applicable legal re-quirements.
(Rechargable) Batteries
As an end user, you are obligated by law (battery ordinance) to return all
used batteries and accumulators, disposal of the household waste is
prohibited!Batteries/accumulators containing harmful substances are marked
with the symbols be-low, which indicate the prohibition of disposal via
household waste. The designations for the heavy metal are Cd = cadmium, Hg =
mercury, Pb = lead (designation stands on battery, for example, under the
rubbish symbols on the left).You can dispose of your used batteries free of
charge at the collection points of your muni-cipality, our branches or
wherever batteries are sold.They thus fulfill the statutory obligations and
contribute to environmental protection.
WEEE ordinance
Electrical products do not belong to household waste. You can dispose of your
old, used electrical products free of charge at the public collecting points
of your municipality.
Safety Notes
Do not use your lithium polymer cells until you have read and fully understood
all safety instructions. This lithium-polymer instruction booklet contains
important safety instructions to avoid potential hazards that could lead to
injury to persons or equipment. For damages caused by improper use, storage
and / or charge of the batteries, which are not in compliance with the safety
regulations, we can not assume any liability or guarantee and do not pay any
damages. The guarantee claim of an accumulator automatically ends with the
manipulation by the acquirer. These include e.g. the removal of components
(cables, heat shrink tubing, PCB), the self-assembly of individual cells into
one pack, the re-sol-dering of cables and boards. It is generally recommended
to have special packs made exclusively by the manufacturer, as they can be
used in a rational, high-quality manner and according to the safety
conditions.
Storing:
Never throw lithium polymer into water or expose it to moisture. Also, they
must not be stored near fire, hot and / or hot places, in the sun or near
combustible materials. Cells that heat to more than 60 degrees Celsius can
destroy themselves or begin to burn. Therefore, always keep lithium-polymer
batteries in a fire-proof place. Keep out of the reach of children!
LiPo batteries should generally not be stored longer than one month. For a
longer storage, a battery should only be charged up to approx. 50-70%.
Avoid short circuits:
The poles of the lithium polymer battery / rechargeable battery must not come
into contact with metal objects accidentally or deliberately, as this usually
causes a short circuit! In the case of a short circuit, an extremely high
current is generated in milliseconds, which can lead to overheating of the
cell, leakage of electrolyte and consequently explosion and flame formation.
Avoid swallowing electrolyte fluid or contact with eyes, skin or mucous
membranes.
Damage to the aluminum laminate sheathing:
Lithium polymer cells must never be opened, separated, deformed, bent or
brought into contact with other packs or soldered. Soldering tags must not be
bent, torn or thrown to the ground. This can cause an internal short circuit
and an explosion with flame formation. Also, be aware that the electrolyte
fluid contained in an LiPo battery is harmful to health.
Charging:
Charge lithium-polymer cells only with suitable charging devices or
appropriate charging programs.
The max. charge current must not be more than 1C (single capacity); For an 880
cell max. 880mA, for a 1100 cell max. 1100mA, for a 1800 cell max. 1800mA,
etc. The charging voltage must not exceed
4.2V per cell!
If the cell overheats too much (> 50 ° C) or increases the cell voltage above
4.2V, the charge is to be terminated immediately! Never use stan-dard chargers
for Ni-Cd or Ni-MH! This can also lead to the leakage of electrolyte and the
risk of explosion. Li-Po‘s should only be charged cold (room temperature
).Lithium-polymer cells may only be charged and stored on a fire-proof, non-
flammable base or in suitable containers. Also avoid unattended loading!
Discharge:
The specified discharging currents must be adhered to. The pulse loadings are
in a millisecond range and should never be used for continuous current
applications. The cell voltage must not fall below 2.9V, otherwise the cell
will be destroyed irreparably. In any case, the discharge must be aborted
before an explosion can be avoided. Reload your LiPo as soon as you notice the
first performance losses.
Usage:
Never use a LiPo battery with other batteries. An unwanted discharge can
destroy the LiPo cells or the battery used.
WARNING:
Due to the enormous energy density, lithium-polymer cells can ignite or even
explode when damaged.This can be caused by extreme overcharging, accident or
mechanical damage, etc. It is therefore extremely important to monitor the
charging process. After an accident, the pack should be checked at the very
least. For example, the pack may have been damaged by an accident but will
only heat up after half an hour. In case of damage, keep the pack under the
most careful observation. The use of a defective battery in an electronic
device can cause damage to it.
Case of Fire:
If lithium polymer cells catch fire, do not use water as a extinguisher, as
this will only foster and aggravate the fire! Please ask your local fire
brigade for suitable extinguishing material which should always be within
reach (eg dry sand).Also avoid inhalation of the lithium gases, as this can
lead to irritation of the mucous membranes, cough, breathing problems and
laryngeal inflammation. These complaints can also occur with a time lag.
Disposal:
Batteries contain toxic substances. Therefore, do not throw used lithium
polymer cells into the household waste, but dispose of them accor-ding to the
relevant laws. To avoid accidental short-circuiting, always tape the battery
pack with an insulating tape.Lithium cells may only be discharged into the
battery collecting receptacles when they are unloaded in the case of trade and
public waste disposal vehicles. If the cells are not fully discharged, these
must be protected against short circuits as a precaution on the poles with
adhesive tape.Safety when handling lithium-polymer batteries is only
guaranteed if the safety instructions described above are follo-wed and the
LiPo‘s are not subjected to any extraordinary stress.Improper use can destroy
the cells or result in personal injury.We can not be held responsible for any
damage to persons, models or cells.
About the technology
Lithium-ion polymer batteries (in short: LiPo) are completely based on Li-Ion
technology.The difference to the Li-Ion battery is in the electrolyte.It was
thickened and combined with a polymer film. Thus, it is no longer liquid or
semi-liquid. These characteristics result in an extremely flat battery with a
very high energy density with 3.7 V instead of 3.6 V with Li-Ion.
Current rating
This varies depending on the manufacturer between 2C and 90C. Please pay
attention to the manufacturer‘s instructions.
Charging
The rechargeable battery can be recharged at any time, it does not have a
„lazy effect“ and must never be unloaded manually.If the battery is discharged
below 3V, it must be charged with 0.1C up to approx. 3 – 3.6V. This ensures a
gentle summons. The battery is then charged up to the charging voltage of 4.2
V (exactly: 4.235 ‘with 0.5 – 1 C. A charging current of 2C is also possible,
but can shorten the life of a battery (please note the manufacturer‘s
instructions).A must for the battery care are LIPOBALANCER. The use of such a
device leads to a significantly longer running time of the LiPo batteries. A
balancer ensures that no overcharging takes place.For a transfer it may, inter
alia, also come when the cells of a pack drift over time, there are various
causes for this. Deviations occur, for examp-le, after prolonged storage due
to different self-discharges or different charging effects after several
charging cycles.
Example:
In the normal case, a pack with four parallel and four series-connected cells
(4s4p) has a lower voltage than the outer ones, since they become warmer
during operation and thus have a higher self-discharge. After a few cycles,
the difference is perhaps only 0.02 or 0.05 volts, but after 30 cycles one may
already observe differences of 0.2 volts, depending on the cell and discharge
depth.If this pack is now charged with a voltage difference of 0.2 Volt, the
charger will charge as before also up to 16.8 Volt total voltage. However,
this voltage will no longer be evenly distributed among the four groups
connected in series. The cells are now loaded, for example, as follows: Group
1 – 4.3 volts, Group 2 + 3 – 3.1 volts, Group 4 – 4.3 voltsThe cells with 4.3
volts charged cells age very fast, which is not immediately noticeable until
the next flight.In the unloading cycle, the individual groups are now unloaded
accordingly. While the outer cells are e.g. Still have a charge of 3.6 volts,
the inner cells lie at approximately deep discharged 2.4 volts.With an LiPo
balancer, this misconduct can be circumvented by balancing the cells of the
pack (Lifetime is thereby extended). In addition, the user is informed of the
state of each cell during each charging process, as a result of which
expensive measurements are omitted.
