possibly causing injury to yourself.
11
TURNING THE MODEL ON
TURNING THE MODEL ON
❏ Place the helicopter on its side and open the battery compartment door.
Connect the fl ight battery and place the battery in the compartment as shown.
❏ Carefully place the extra wiring into the battery compartment and close the
battery door. Place the helicopter onto a fl at surface and proceed to the next step.
12
❏ Your Novus helicopter uses a 2.4GHz system that requires linking the
transmitter to the receiver when the unit is powered up. With the transmitter
turned off, connect the fl ight battery to the helicopter. Then place the model
on a fl at surface and turn the transmitter on. You will notice that the trim tab
indicators are moving and the navigation lights on the helicopter remain solid.
This is an indication of the linking process. Allow the helicopter to remain still
and do not move the transmitter sticks during the linking process.
❏ Two loud tones will be emitted from the transmitter. Continue to allow the
helicopter to remain still. After a couple of seconds the navigation lights will
begin fl ashing rapidly. This indicates that the binding process is taking place.
The tail navigation light will stop fl ashing and the anti-collision beacon on top
of the helicopter will begin operating. This indicates that the transmitter and
helicopter have bound properly and the helicopter is now ready for fl ight. Always
step 15 feet [4.5m] away from the Novus Helicopter before operating the throttle.
Your Novus helicopter has a safe start feature built in that prevents
the motor from activating unless the collective stick has been lowered
to the lowest position. If the motor won’t run and turn the main blades,
please make sure the collective stick is all the way down and leave it
there for a couple of seconds. Then try moving the stick up slowly.
13
TRANSMITTER CONTROLS
TRANSMITTER CONTROLS
All controls are described with the tail pointing directly toward you. This is
the best way to fl y in the beginning since it keeps the control inputs oriented
the same direction. Once you start getting comfortable you can work on side
hovering and nose-in.
The dual rate switch provides dual control rates for the cyclic and tail rotor controls.
Please use the low rate until you become accustomed to your Novus.
The Heli-Max Novus UH-1D Huey CX is a lightweight helicopter. Taking that into
consideration, you should only fl y indoors or in calm winds less than 1mph. The
Novus should be fl own in a large area of at least 50 feet [15.25m] square with
no obstacles.
The Novus UH-1D Huey CX is lightweight and due to this it does not fl y well in
ground effect (air disturbance when the model helicopter is hovered below 1
foot [30cm]). The model should be fl own at a minimum altitude of 1 foot [30cm]
to avoid the instabilities cause by ground effect.
Crashing
If you have operated radio control models in the past then you probably already
realize that it is not a matter of “if” you are going to crash, it is a matter of “when”
you are going to crash. Once you realize the model is going to collide with
something or crash into the ground, you should always bring the throttle stick all
the way down to stop the main rotor blades from rotating. If you can remember
to do this, chances are you will not damage the helicopter in the crash. The
main rotor blades carry a lot of RPM and inertia during fl ight. Cutting the power
to the main rotor blades will prevent most of the crash damage.
Takeoff
Slowly add power, observe the model and make all of the necessary corrections
to keep the model level. If you feel a trim adjustment is needed, lower the throttle
to idle and make trim adjustments before lifting off for the fi rst time. You will fi nd
that model helicopters never allow you to return the sticks to center. You just
need to position the stick as needed to maintain a steady hover.
You will notice the cyclic controls lag behind your inputs. This is normal and
something you get the feel for with time. It’s normal to drift around in a hover
until you become accustomed to fl ying the model. The cyclic controls are fairly
sensitive so only small movements are necessary.
Hovering
Once the helicopter is up in the air, simply try to hold the helicopter in one spot.
If this is your fi rst model helicopter, it will require some practice. Wind or air
currents have a big effect on the stability of the helicopter as well. Be patient
and slowly work forward, as trying to rush the learning process can be costly.
18
Landing
Level the helicopter into a steady hover and slowly decrease power until the
helicopter settles onto the ground.
Basic Maneuvers
Once you become comfortable with hovering at different orientations and
landing, it’s time to move on to more advanced 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 feel
uncomfortable, then bring the tail back toward you. Once you start getting
comfortable, try moving the helicopter to the side. Then turn back and fl y back
to the other side in straight lines. Then work into rotating the helicopter around
360°, which is called a pirouette. The helicopter can drift during these so make
sure you have plenty of room when you fi rst start practicing.
Nose-in Hovering – After pirouettes it’s time to move on to nose-in hovering.
Take off and climb to 10 feet [3m]. Practice half pirouettes from tail in to nose-
in hovering and try to lengthen the delay in between. This will give you a little
practice nose-in and still give you a chance to get out of trouble. As your skills
improve you’ll remain nose-in for longer periods of time.
GOOD LUCK AND GREAT FLYING!

MAINTENANCE AND REPAIR
MAINTENANCE AND REPAIR
The Heli-Max™ Novus UH-1D Huey CX is an extremely small helicopter.
Working on a model this size will require small tools. The DTXR0170 DuraTrax®
Precision Phillips Screwdriver 00x75mm is recommended. On occasion it will
be necessary to replace damaged parts after a crash. Please use this section
as a guide to performing these steps.
Main Rotor Blade Replacement
Remove the blade bolt using a #00 phillips screwdriver. After the blade bolt has
been removed, slide the rotor blade out of the blade grip. Reinstall the new blade,
ensuring that the holes within the blade and blade grip are aligned properly.
Reinstall the blade bolt.
20
Main Rotor Grip Replacement
Remove both blade bolts and main rotor blades. If working on the upper rotor,
remove the fl ybar and linkage. The only way to remove the blade grip is to cut
the grip on both sides as shown. Remove the two halves. Remove the two metal
pivot pins from the head block. Slide the two metal pivot pins from the center of
each grip into the blade grip. Press these pins in until they are fl ush. Align the
new blade grip on the head block and from the outside of the grip. Push the pins
into the head block. Install the fl ybar and main rotor blades.
Replacing the Flybar
Remove the fl ybar linkage from the blade grip. Press outward on one side of
the head block and simply rotate the fl ybar carrier from the head block. Once
the fl ybar carrier has been removed, press the fl ybar weights inward and turn
them 90°. Now pull them off the end of the fl ybar. Remove the fl ybar linkage
from the old fl ybar and install the linkage onto the new fl ybar. Install the fl ybar
weights onto the new fl ybar and slide the fl ybar pivot back onto the head block.
Reinstall the fl ybar linkage.
21
Replacing the Landing Gear
Remove the four landing gear screws and carefully remove the landing gear.
Route the battery lead through the new landing gear and place the landing gear
back onto the helicopter. Install the four landing gear screws.
22
Replacing the Main Gear
The Novus Huey uses an inner solid main shaft and a hollow outer main shaft.
To access the main rotor gears it will be necessary to remove the landing gear
fi rst. Remove the lower main gear retaining screw. The lower gear will simply
drop down off the main shaft. If you need to replace the upper main gear, slide
it down off the main shaft and reinstall the new gear, ensuring that the fl at
spot molded inside the gear aligns with the main shaft. Reinstall the lower
gear, ensuring that the screw aligns with the fl at spot machined on the inner
main shaft.
Replacing the Main Shaft
The Novus CX uses an inner solid main shaft and a hollow outer main shaft.
Remove the lower main gear retaining screw. When performing the following
step please be careful not to lose any small bearings or bearing blocks. Slide the
inner shaft and upper rotor head from the outer main shaft by pulling upwards.
If you need to remove the lower shaft, disconnect the servo linkages from the
swashplate and pull upwards. Transfer necessary parts from the old shaft to the
new shaft and install following the reverse order listed above.
23
Tail Rotor Blade Replacement
Carefully pull the tail rotor from the tail motor using your fi ngers. Press the new
tail rotor onto the shaft. Verify that the tail motor spins easily.
