OPERATIONAL WARNINGS
OPERATIONAL WARNINGS
●Please allow a 10 minute cool down period after each flight so the
motor controller and motor can cool down. Failure to do so may cause
loss of control due to the controller overheating and shutting down.
●Inspect the main rotor blades and blade screws before each flight for nicks
or loose components. If any damage is found or if the blades have been
damaged, replace the blades before flying the model again.
●The motor controller has a soft cut function that will reduce the power output
to protect the flight battery. Toward the end of a flight you will notice a slight
power reduction. Land the model immediately. The flight time of the EC145
can be as long as 6 minutes (Standard Hover) but this will vary depending
on your flying style.
●After a crash you must inspect all plastic parts on the helicopter for damage
before attempting to fly the model again.
●Always unplug your battery from the helicopter after use.

Transmitter (RTF model)
Please fully read the transmitter manual included with your helicopter to learn
more about how to use and adjust your TX610.
Important Transmitter Functions
The Throttle Hold Switch (HOLD/
FLAP) is used to disable the power
output of the motor but has no
effect on the other controls. The
throttle hold function is intended
for autorotation landings off power
descent to landing; this maneuver
is really not realistic with a motor
driven tail. In addition to autorotation
the throttle hold function can be
used as a safety switch while
handling the model since it disables
power to the motor. Turn the transmitter on and set the throttle hold switch to
the on position. Now you can safely connect the flight battery without having to
worry about inadvertently moving the throttle stick once you place the model on
the ground. Verify that the idle up switch is off and the throttle stick has been
moved to its lowest position. Then, simply turn the throttle hold off. The model
is now ready to fly. Another use for the throttle hold function is to disable the
motor before a crash without having to drop the collective stick, possibly forcing
the model into the ground.
The UP-1 function is enabled and
ready to use. The UP-1 Switch
(UP-1/GEAR) function is used for
aerobatics. If you are a beginner to
aerobatics, remember this switch
sets the motor speed (see your
TX610 manual for details) while
still allowing positive and negative
pitch control. This means if you get
confused flying, pulling the throttle
stick back WILL NOT decrease the power to the motor but rather add power.
Hence it’s a good idea to learn to use the Throttle Hold Switch when you feel
a crash is imminent!

GET THE MODEL READY TO FLY
GET THE MODEL READY TO FLY
Install Batteries In The Transmitter
Remove the battery cover
from the back of the transmitter
and install eight “AA” batteries
into the transmitter. Double-
check the polarity of each
battery before replacing the
battery cover.
Charge the Flight Battery
Plug the wall power supply
into any 110V standard outlet.
Plug the remaining 4mm plug
into the side of the charger
box. The center front panel
LED will light, letting you know
the charger has power. Plug
the helicopter's power battery
into the open connector of the
charger. The charger will
beep twice letting you know
the battery is connected.
At this point you can select
a slower or faster charge
rate by pressing the - or +
buttons located on the face
of the charger. While the LED
is illuminated you will need
to press the charge button.
You will hear 3 beeps and the
charge cycle will begin.

11
When charging is complete all the LEDs will flash and you will hear a steady set
of beeps coming from the unit. Unplug the flight battery. It is now ready to use.
NOTE: Your battery charger ranges from 0.3 AMPS to 0.7 AMPS in 0.1 AMP
increments. The higher the value, the faster the battery will charge. We recommend
charging on the 0.6 AMP setting (Default).
Turn the Transmitter On
Verify that the HOLD/FLAP and UP-1/GEAR functions are off, and slide the
power switch up to turn the transmitter on. If the transmitter is turned on with the
HOLD/FLAP, UP-1/GEAR or throttle stick forward, the screen will show “3D” or
“T-H” and a warning will sound. Turn the HOLD/FLAP and UP-1/GEAR functions
off and/or move the throttle stick to the low position to continue. Now is a good
time to make sure the electronic trim buttons on the transmitter are centered.
We do not need to use them as the incredible Heli-Max TAGS™ system controls
all flight center trims.
Install the Flight Battery
1. Slide the front portion of the
canopy forward to expose the battery
compartment.
3. With the helicopter placed on a flat
surface, plug the battery in, taking care
not to bump or move the helicopter.
2. Slide the battery into the helicopter.
Make sure the battery is slid all the way
to the front of the battery tray.
4. Reinstall the front canopy by aligning
the guide slots and slipping it into place.

12
Once the flight battery has been connected, always handle the
helicopter as if it has full power available. The helicopter must remain
still for the gyro to initialize properly. This process is instantaneous
after the helicopter is held still. Turn off the HOLD/FLAP switch and
the helicopter is ready to go. Now is a good time to turn on the HOLD/FLAP
switch until you are ready to start flying.
To learn more about flying your EC145, skip forward to the “Flying Your EC145”
portion of the manual.
™
Your EC145 uses the Tactic SLT™ protocol. This means, with the simple addition
of the Tactic Anylink™ to your favorite transmitter, you can enjoy your Heli-Max
EC145 with a familiar transmitter. After the purchase of your Anylink, make sure
to fully read the instructions so you understand how to properly and safely use
the Anylink system.
When using the Anylink you must make sure to follow the proper
mapping procedure for your radio brand. Failing to do so could cause
an un-safe condition. How to map your transmitter, as well as a list
of compatible transmitters is included with your Anylink. You can
find this and more information on the Tactic website. www.tacticrc.com
®
LINKING
LINKING
The Tx-R version of the EC145 requires you to link your transmitter to the helicopter.
When using a Tactic SLT transmitter or Anylink, one must follow the procedure
below to complete the task. If you need to link or re-link for any reason, here is
the proper procedure to do so.
1. Turn on the transmitter, making sure all the switches are in the back
position and the throttle is down.
2. Remove the canopy from the helicopter and locate the small black button
near the front of the PC board.
3. Place the transmitter in close proximity to the helicopter (1 to 2 feet away).
4. Plug a fully charged the battery into the helicopter.
5. Press and hold the Link button for 3 seconds or until the LED remains on.

13
6. Monitor the flashing LED.
When it stays on “no flashing”
your transmitter is now linked
to the helicopter. Note:
There is a second LED in
the center of the PCB. When
your transmitter is linked and
the helicopter held still, this
LED will flicker letting you
know your TAGS stabilization
system is working and ready.
Here are some Transmitter setup guidelines to help you
get started.
FUTABA: You will find that regardless of the Futaba system you choose, the
basic setup is the same. This includes the Futaba 6EX, 7C, T6J, TJ8 as well as
others. We have listed the setup of a Futaba T6J transmitter. It’s also worth noting
that even though the EC145 uses 120 degree CCPM (cyclic-collective-pitch-
mixing), with the Heli-Max TAGS system you must select the 90 degree swash
arrangement. In a Futaba system this is called H-1 or 1-S under swash type.
The setups listed will get you going and might suite your flying style. If not please
feel free to make adjustments to suite your flying style.
Here is the setup for the Futaba 6J.

FLYING YOUR EC145
FLYING YOUR EC145
Takeoff
During your first flights it is important to have light winds. Also, if you are flying
from grass, place a rubber mat or pad down on the grass so the small rotating
parts don’t get hung up in the grass.
Turn off the hold switch and very slowly add power and observe the model.
During “spool up,” it is important to note that the torque of the main blades can
cause the helicopter to rotate slightly clockwise. This is normal.
Your EC145 has the incredible Heli-Max TAGS system. The TAGS system takes
care of all center trim functions of the transmitter. Having said this you do not
need, or want, to move or adjust the trim buttons during flight. If you notice any
slight flight drifting, give it some time. After the helicopter's swash and servo
links “break-in,” the drift will diminish.
Hovering
Once the helicopter is in the air, simply try to keep the helicopter in one spot.
This will take some practice. Remember that even a light breeze will have an
effect on the stability of the helicopter, so please take your time, be patient and
wait for a calm day.
Landing
Level the helicopter into a steady hover and slowly decrease power until the
helicopter settles onto the ground. You might notice as the helicopter is ready
to touch down it moves around a little. This is normal as the helicopter enters
ground effect. Remember to unplug the battery from the helicopter after your
flight is complete.
®
BASIC MANEUVERS
BASIC MANEUVERS
Once you are comfortable with hovering in one place, start working on orientations.
This means hovering the helicopter in all positions, nose to the right, nose to the
left and the nose pointing at you (nose-in). Getting good at this fundamental
discipline will allow you to progress much faster in some of the more advanced
flying maneuvers.
Slow Pirouettes
Add a small amount of tail rotor (left or right) and try rotating the helicopter slightly
sideways and see if you can hold it there. If you become uncomfortable you will
want to bring the tail back towards you. Once you are comfortable, try moving

16
the helicopter to the side and turning back. Then fly back to the other side in
straight lines. You can try rotating the helicopter around 360°, which is called
a pirouette. The helicopter can drift during this maneuver so make certain you
have plenty of room when you first start practicing.
Forward Flight
Now it’s time to work into basic forward flight. Just take the basic hovering
maneuvers listed above and slowly fly out farther and faster and always bring
the helicopter back after one pass. Practice controlled slow flight in close as
well. The more time you spend practicing here, the easier things will be later on.
Chandelles
Your first step is chandelles. Fly straight across in front of you and pull up to a
45° angle. Now at the top, when the helicopter slows down to a stop, apply left
or right tail rotor to bring the nose around 180° and continue back down the 45°
angle. As you progress with the maneuver you can pull a greater angle than
45°, but 90° would be considered a “stall turn”.
