even death.
This RC helicopter is not a toy! Incorrect
operation may cause serious injury or damage. If
you are a novice pilot we strongly suggest that
you should find an experienced pilot in RC
helicopters to assist you.
It is absolutely necessary to read the manual of
the helicopter before operation ,it is mandatory
to check all control systems and mechanical
linkages for proper operation before every flight.
Safety first!
8. Since the helicopter can fly very fast, it may
cause potential danger, so the choice of the flight
field is of great importance.
9. Do not fly near crowds, high voltage cables or
trees to ensure the safely of yourself and others.
10. Do not fly in bad weather such as rain or
thunder storms to ensure the safety of yourself.
11. It is suggested to fly at an open field for
beginners, and fly with a training set to practice
Please Note: The Rapier features automatic binding
when the TX & RX are turned on. If you happen to be
flying with a friend or colleague using the same
radio system, please ensure that one is properly
bound before binding another, as it could be
possible for one TX to be bound to two Rapier
receivers if by chance they are turned on at exactly
the same time.
It is important that you only charge the included
3S 11.1V 2200mAh Li-Po Battery with the included
3S 11.1V 1.0-Amp Li-Po Balancing Charger. Your
battery is equipped with special Charge Protection
Circuitry and Balance Charge Leads with connector
that are only compatible with this charger.
Attempting to charge the battery using another LiPo charger or non Li-Po compatible charger could
result in serious damage.
We have put together a quick start guide to get
you up and running with your Rapier ASAP. If you
are not a novice you can be up and running with in
the hour.
These models are set up and factory tested to fly
out of the box. Minor trimming may be required and
some basic set up tips are advised for the more
advanced pilot.
Out of the box your Rapier will hover and in the
3D Fly mode is more than capable of basic 3D, with
a tweak or two to the settings
it is even capable of the more advanced 3D. We
have tested many of them out of the box and have
them flying inverted as well as flipping about with
no changes at all to the out of the box set up.
If you are a first time modeller it is
recommended you use a flight simulator to
familiarise your self with the basic controls, the
RealityCraft RC Helimaster SIM is a good starting
Please familiarize yourself thoroughly with the
Battery Warnings and Guidelines section before
continuing. A detailed Guideline and Safety page on
handing and charging LiPo batteries can be found at
the rear of the manual. The included 3S 11.1V 1.0Amp Li-Po Balancing Charger will charge a near
fully discharged (not over-discharged) 3S 11.1V
2200mAh Li-Po battery in approximately 1.5-2.0
hours. Insome cases the charge time may be shorter
depending on the actual amount of capacity left in
the battery after a flight.
NEVER charge the battery unattended.
NEVER charge the battery by flammable material.
ALWAYS charge the battery in a tin or LiPo safe
sack, away from combustable material to contain
any possible fire risk.
Once you are familiar crack on with our quick
start check over and 10 step check:
1. First of all set up your flight battery to be
installed in the machine using the supplied
Velcro to hold the battery in position in the
battery tray, make sure it is secure and not likely
to come loose during flight.
2. Put the battery on charge using the supplied
balancing charger, this should take no more than
3. Put the 8AA batteries in to the transmitter (not
4. Check all the switches on the transmitter are in
the away / up position when ever you turn it on
and the throttle is at the low position, the most
The Li-Po battery included
with your Rapier 3D will
arrive partially charged. For this reason the initial
charge may only take approximately 30-50 minutes.
The charger requires up to 3-Amps of 11.515 Volt
DC input power that can be supplied by the optional
AC to 12V DC, 3-Amp Power Supply for convenient
charging anywhere an AC outlet is available. NEVER
attempt to power the charger from an AC outlet
without the use of a proper AC to DC adapter/power
important note here is to ensure the FLY switch
in the up / away position or NOR. The transmitter
has a safety feature to stop it turning on at full
throttle but treat it like a loaded weapon when
the model and the heli are turned on.
5. Check the model over paying important attention
to make sure all ball links are connected, also
check the main and tail blades as well as giving
the model a good once over for anything obvious
6. Put your fully charged battery back in to place
and secure it in the model with velcro.
7. Put the throttle at the low position and turn on
the transmitter.
8. Now plug the battery into the speed controller
and put the canopy back on – be careful as the
helicopter is now armed and dangerous
9. Put the model in a safe place to take off and take
a few step back and test the control surfaces,
right aileron for right aileron, backward for
backward and left tail command will send the
lower tail blade turning clockwise when viewing
the model from behind, although this is not an
issue out of the box it is worth a quick sanity
check each time you go out to fly.
10. Slowly lift off and enjoy.
bottom of the box the throttle is reduced. This
introduction of negative pitch and more power will
mean you can start to fly the model inverted, roll,
loop and general fly the model around with a little
more vigour.
When you get to the stage where you want to do
more 3D flying you may want to introduce more
throttle a the mid stick throttle position.
We would recommend to use the following
throttle settings, 100% at low stick, 80% at mid
stick and 100% at high stick position. To achieve
this you will need to follow the next steps:
NOTE: disconnect the three bullet connectors
between the motor and ESC.
1. Flip dip switch EXP to the ON position, with dip
switch PLT/PITCH and RUDD/GYRO SENS (dips 9
and 10) in the off position.
2. Now turn the rotational dial on the front top right
of the transmitter clockwise to the + position.
3. Now turn the dip switch EXP (dip 8) to the OFF
position and turn the transmitter off and on.
Should you be unfortunate enough to bump you

The Rapier is a great model offering some
amazing performance and great value. Here are a
couple of things to ‘DO’ to make sure you can enjoy
it for as long as possible:
When flying inverted or flying around you may
want to increase the throttle at the mid point with
the FLY switch in the 3D position.
The basics of flying inverted involve introducing
negative pitch while increasing the throttle, this is
unlike the normal throttle setting (in the up / away
position) where when you bring the stick to the
• Do check the model over before and after every
flight, pay special attention to the blades and
control rods / balls.
• Check for a full charged transmitter and main
battery pack.
When the stick is pushed up, the swashplate
should raise, increasing the pitch of the main
1. First turn the transmitter on and lower the
throttle/collective stick completely, also make
sure the FLY mode switch is in NOR or away
fly mode
switch in
2. Once the battery has been properly positioned,
fasten the hook and loop strap around the
battery for added security. Then, plug the battery
into the battery leads of the ESC.
With the stick pulled back down, the swashplate
should lower, decreasing the pitch of the main
Although each Rapier 3D is control tested at the
factory, it is a good idea to test the controls prior to
the first flight to ensure none of the servos, linkages
or other parts were damaged during shipping and
handling. Before proceeding, disconnect the three
bullet connectors between the motor and ESC. It is
not safe to perform the control test with the motor
connected to the ESC.
Position the helicopter to view it from the left or
right side. Move the left-hand stick up and down to
check the collective pitch control.
Again viewing the helicopter from the left or right
side, move the right-hand stick forward and aft to
check elevator pitch control. When the stick is
pushed forward, the swashplate should also tilt
While viewing the helicopter from the rear (tail
boom toward you), move the right-hand stick left
and right to check aileron roll control. When the
stick is pushed to the right, the swashplate should
also tilt right.
With the stick pulled back, the swashplate will
tilt toward the rear.
With the stick pushed left, the swashplate will tilt
to the left.
While viewing the helicopter from the rear (tail
boom toward you), move the left-hand stick left and
right to check rudder/tail rotor pitch control. When
the stick is pushed to the right, the tail pitch slider
should move to the left.
With modern day gyros you have the option to
adjust the gain (the amount of correction it gives)
both up and down. The more you have the more
stable the tail and easier it is to control, but if you
have too much the tail / nose can wag. Out of the
factory there is no need to adjust anything, however
if you make tweaks, change the servos or change
the head speed you may need to adjust this.
Another feature of this transmitter is rudder
mixing which compensates for RPM changes but
with the Gyro in this machine you wont be needing
that so when following the instructions below
please ensure dial V1 in the top right is turned anti
clockwise to the negative value position.
1. Flip the RUDD MIX ./GYRO SENSE dip to the on
With the stick pushed left, the tail pitch slider
should move to the right.
2. Turn the V2 dial, top left of the transmitter to the
12 O’clock position, this is approximately 50%
and should be a starting point, if its too lively,
turn it up (clockwise) and if it wags turn it down
(counter clockwise). It is possible to adjust this
on the bench or whilst flying (obviously once
After powering the model on and allowing the
ESC and gyro to properly arm and initialize, bring
the main rotor blades of your Rapier 3D up to speed.
You can check the blade tracking either on the
ground or in the air at approximately eye level. It
might be a good idea to have an assistant on hand
to help sight the blades. Again, be certain to
maintain a safe distance of (20-25 feet) from the
helicopter when checking the tracking of the main
rotor blades.
Once the main rotor blades have been brought up
to speed, note which blade is running low and
which blade is running high (by the colored tracking
tape). Helicopters with variable pitch on the main
rotor blade all have pitch control links .You only
need to turn the control link of the higher or lower
blade to bring it in line. With the Rapier the
adjustment to the main blade holder is on the
trailing edge, if the blade you are adjusting is the
high blade in the tracking excersise detailed above
then you need to bring this down, so unscrew the
ball link to the trailing edge by 1 turn and
remeasure, if you need further adjustment and go to
the lower blade and bring this up by screwing the
ballink on the linkage rod by one complete turn.
When making a rod longer ensure you leave enough
thread into the ball link. So as an overview the best
way is to adjust both pitch control link is at the
same time.
3. When the required gain is achieved flip to DIP
back to off.
Caution: Be sure to maintain a safe distance from
the helicopter (20-25 feet) when tracking the main
rotor blades.Blade tracking is a critical element to
the flight performance of just about any helicopter,
Main rotor blades that are out of track may cause
vibration, instability, and loss of power due to
increased drag. Although the main rotor blades of
each Rapier 3D helicopter are tracked at the factory,
minor adjustments to blade tracking may be
required after blade changes, linkage adjustments
or repairs. To check main rotor blade tracking and
make any required adjustments, please note the
following tips: Before proceeding with the test flight
of a new model, or any model to which changes or
repairs have been made, be certain that the main
rotor blades have been properly installed and
secured. The main rotor blade mounting bolts
should be tightened so that the blades can pivot in
the blade grip when moderate pressure is applied.
Never allow the main rotor blades to swing freely in
their grips.
Blades out of track
need adjustment
If the main rotor blades are still out of track, you
need to adjust another blade, and repeat the
process to check the blade tracking and make
adjustment until both blades run in track. With
proper adjustment ,the helicopter will fly stably and
the swash plate to the control arms these too
should be horizontal / flat. In turn this should
give 0 degrees pitch out put on the blades, if
needed adjust the rod links equally each side to
get it level – this is the first check and a great
bench mark for a rebuild.
The pitch travel and factory set up for this model
is perfect for most peoples tastes right out of the
box and should not need changing. However should
you be experienced or wish to tweak this or should
you need to change this at a later date do a rebuild
then the following steps can be taken to check and
correct / check the pitch range.
1. Check the speed controller is not connected to
the motor to avoid any unwanted spinning up of
the main blades.
2. Flip dip switch PLT / PIT to the ON position, this
will enable the pitch travel adjustment function
3. in FLY mode Normal or the away position, both of
the dials V1 and V2 function, V2 will adjust the
whole range available, i.e. +/-12 degrees down to
-0 and dial V1 will just lower the bottom end,
adjust as needed.
Before starting this process please disconnect
the motor from the speed controller:
1. Check the speed controller is not connected to
the motor to avoid any unwanted spinning up of
the main blades.
4. Flick in to FLY 3D mode and the V2 dial is the
only one that functions allowing top and bottom
pitch adjustment only.
2. You can now turn the transmitter and model on.
5. Once complete flick the DIP switch PLT/PIT to off
and restart the model and TX.
3. With the FLY switch in 3D mode (towards the
pilot) put the pitch stick to the middle, this will
centre the servos, please make sure all servo
arms are centred and horizontal, also running up
6. Once set up is complete reconnect the motor.
