I. Kit Introduction
R/C Helicopter Safety
A radio controlled model helicopter is a technically complex device that must be built and operated with
care. It is also a fascinating and challenging part of the R/C sport, the mastery of which is very rewarding.
A model helicopter must be built exactly in accordance with the building instructions. The kit manufacturer
has spent much time and effort refining his product to make it reliable in operation and easy to build. The
essentially bolt together construction can proceed quite rapidly, giving the builder a strong sense of
accomplishment that encourages hasty progress from one construction phase to the next, so that the
completed model can be more quickly seen and enjoyed. It is essential to recognize and guard against this
tendency. Follow building instructions exactly. Vibration and stress levels are high and all fasteners and
attachments must be secure for safe operation.
Note that this is the first use of the word SAFETY in these comments. Previously the kit manufacturer’s
efforts to ensure reliable operation were mentioned. That is ALL that he can do. Safe operation is the
responsibility of the builder/flyer and starts with careful construction and continues with selection and
installation of reliable radio equipment and engine.
The need for safety is nowhere greater than at the flying field. A number of guidelines for safe flight have
been developed by experienced flyers and are set down here. It is urged that they be read, understood
and followed.

Guidelines for Safe R/C Helicopter Flight
•
•
•
•
•
•
•
•

Fly only at approved flying fields and obey field regulations.
Follow frequency control procedures. Interference can be dangerous to all.
Know your radio. Check all transmitter functions before each flight.
Be aware that rotating blades are very dangerous and can cause serious injury.
Never fly near or above spectators or other modelers.
If a beginner, get help trimming the model first and flight training later.
Don’t “track” the main blades by holding the tail boom. This is a temptation to builders who cannot
hover yet and is very dangerous.
Follow all recommended maintenance procedures for model, radio and engine.

WARNING!
This helicopter is not a toy, but a complex flying machine that must be assembled with care by a
responsible individual. Failure to exert care in assembly, or radio or accessory installation, may result in a
model incapable of safe flight or ground operation. Rotating components are an ever present danger and
source of injury to operators and spectators. Since the manufacturer and his agents have no control over
the proper assembly and operation of his products, no responsibility or liability can be assumed for their
use.

III. Kit Assembly Process
Assembly Tips
1. Please note that this assembly manual consists of a photographic journal of the steps necessary to
construct this helicopter. The builder is encouraged to pay close attention to the "building notes"
and other details noted in the pictures and to carefully review all the photo’s in a given step. The
placement of a given part may be better understood when viewing another view of the assembly.
2. Follow the order of assembly. The instructions have been organized into major sections and have
been developed in such a way that each step builds upon the work done in the previous step.
Changing the order of assembly may result in unnecessary steps
3. The photos in this manual are organized within each step to correspond with the order of assembly.
The sequence of the photos within a step is from top to bottom and from left to right.
4. Clean all metal parts: All of the steel parts in this kit are coated with a lubricant to prevent them
from rusting. This coating can interfere with the adhesives and thread locks needed for assembly.
Use a solvent such as alcohol or acetone to clean the various metal parts, especially threads
5. Use only the formula of thread lock as indicated. Model helicopters are subject to vibration and
failing to use the correct formula of thread lock on any non-locking assembly may result in a part
becoming loose or falling off.
6. Sand sharp edges on any frame plate that Velcro® or wires may rub against to prevent them from
being damaged over time by vibration
7. Make sure every bearing runs smoothly after component assembly. If it does not find out why. A
rough running bearing will fail prematurely.
8. As a general rule any bolt that threads into a metal part should have thread lock applied
and any screw or bolt that threads into a plastic part should have thick (ONLY)
Cyanoacrylate adhesive applied
9. Assembly sections contain the following content:
a. The contents of each bag
b. An overview of part relationships
c. Assembly overview
10. Photographs will contain assembly icons that indicate use of thread lock, adhesive or lubricant as
needed. If an assembly has more than one of the same part number, application of thread lock,
adhesive or lubricant will apply to all of the same numbered parts in that photograph Examples of
the icons are as follows:

Thick
Adhesive

Blue
Thread
Lock

Green
Thread
Lock

Lubricant

Grease

Fastener Guide
This page contains a list of all of the threaded fasteners in this kit. They will print at actual size. If
it is not clear what the part number of a fastener is, simply find the fastener on the chart and
match its part number and description

flanged side.

Building Notes:
Do not over tighten bolts. Make
sure pulleys spin freely

Use an allen driver to push a
bearing into each pulley and
seat against the flange

Be careful not to get any thread
lock in the bearings.

Set aside allow the thread lock
to dry before installing the
pulleys.

Aileron

Initial Setup for servo centering

Plug in all servos according to manufacturer’s channel assignments. It is not necessary to connect the throttle channel
at this time.
For Futaba FASST, the following are the default assignments (your system may vary)
•
Ch1 = Aileron
Ch4 = Pitch
•
Ch2 = Elevator
Ch5 = Gyro
•
Ch3 = Throttle
Ch6 = Rudder
In your radio, set the model type for helicopter and set the swash type as 120° CCPM. Check the radio manual to find
the correct swashplate setting and channel arrangement (For Futaba this is SR-3/HR-3).
Channel Layout

Swashplate Type

At this point in the setup you don’t need to power up the ESC but only the receiver and servos. If you are using a
separate Rx battery, plug it into the receiver and proceed. If you are only using an ESC with a BEC for Rx power, don’t
connect the ESC to the motor when you power up for this step.

•
Slide the servo horns for each channel onto each servo exactly in the middle of its travel as shown
•
Failing to get them set at center will create interaction in your swash plate travel.
•
If possible, center the horns on the servos without using any sub trim. As a last resort, use the sub trim
function to precisely center each servo.
•
Make sure you install hex nuts on the ball retainer bolts using threadlock

B)

Setup for Collective, Cyclic and Rudder

For the following steps you don’t need to power up the ESC, only the receiver and servos. If you are using a separate
Rx battery, plug it into the receiver and proceed. If you are only using an ESC with a BEC for Rx power, don’t connect
the ESC to the motor when you power up for this step.
As you go through these setup procedures, make sure that none of the controls bind at full throw. If so, adjust the
individual servo throws until the binding is resolved.

B.1

Setting Swashplate Movements

The first step is to make sure that the servo reversing and swash mix settings are correct for the controls to move
properly.

B.1.1 Collective Movements
For a sport flying/3D setup, a linear pitch curve is appropriate (a straight line- 0%,25%,50%,75%,100%) as your
pitch curve data points.
Pitch Curve - Linear

Check the movement of the collective commands
Starting with the collective, when moving the collective stick up and down, all three servos should work in unison to
equally raise and lower the swash plate.

If the movements are not correct, first make sure that the servos are connected to the correct channel on the
receiver.
If the servos do not move in unison, they can be adjusted by either:
•
•

changing the servo reverse settings for one or more of the cyclic channels
changing the “sign” of individual cyclic channels on the Swashplate mix menu (Swash AFR on Futaba radios).
For example if it is a +50% for a channel, make it a -50% to make it correct. You may have to change this for
one channel or all channels.

B.1.3 Swashplate – Center Level
With the collective and cyclic sticks centered, visually center the swash plate to ensure that it is straight. A swash
plate leveling tool is also helpful in this case. If the swash plate is not 100% level at center collective, looking at it
from the side, as well as the front, use a small amount of sub trim in the appropriate channel to make it level.
Collective Centered

When properly centered, the swashplate will be level from all viewed angles. Also, if the servo arms are the correct
length, all rods will be parallel with the main shaft as shown

B.1.3 Swashplate – Extreme Throws Level
It is now time to make the swash plate level both at full positive and negative pitch. Raise the collective stick to its
fullest position upwards. Visually inspect the swash plate. If the swash plate is not level, use your servo ATV’s
(Endpoints) to adjust each servo to create a level swash plate. Once again, inspect the swash from the front/ back
and from each side to make sure that the swash is level.
Now lower your collective stick and follow the same procedure mentioned above to make your swash plate level when
giving negative pitch.
What this has created is a totally level swash plate during its entire travel.

B.2.2 Pitch Curve Setup
Now center the collective stick once again. If all links have been built per assembly manual’s instructions, a check of
the main rotor blade pitch should find it close to zero degrees pitch. Adjust either the double link from the flybar
cross tube to the bell mixer, or the long linkage from the swash plate to the bell mixer to get the blade angle zero
degrees.

B.3

Rudder Setup

Make sure that the t/r servo and gyro are connected to the Rx according to the manufacturer’s recommendations.
For a typical gyro (like the Futaba 401), set the gain on the tail to roughly 45%.
Set the limits for the tail servo for maximum throw to allow greater servo resolution. Use the Endpoint menu in the
radio to adjust the Rudder ATV’s to adjust your pirouette rate (A recommended starting value is 100%) or follow the
instructions from your gyro manufacturer.

Rudder – Radio Left Rudder

Rudder Servo Left

T/R – Full Left

Now that the tail rotor slider has been adjusted for full travel, enable heading hold in the gyro using a gain of roughly
45%. Check to make sure that the heading hold is working properly. If not, refer to the gyro documentation to
determine the cause.

C)

Setup for Speed Controller

Because of the wide variety speed controllers and the differences in their setup, refer to the manufacturer’s
recommended settings for your specific speed controller.
In some cases as with Futaba radios, you may need to “reverse” the throttle channel direction. Please note the
manufacturers directions in regards to throttle direction settings.
MAKE SURE that the speed controller is properly setup BEFORE connecting the drive motor. If the ESC is improperly
setup, the motor may start unexpectedly causing injury or damage. BE CAREFUL!! Electric motors are capable of
making their full power immediately!
