1. Introduction
Congratulations on your purchase of Century Helicopter Product’s Swift Carbon 550 Kit. The Swift Car-
bon 550 is a high performance machine providing the agility and durability that is expected out of a heli-
copter of this caliber. The attention and praise by the R/C helicopter community is well deserved as the
Century Swift line is unmatched in affordability, quality and performance.
In order to take advantage of your Swift’s performance capabilities we recommend using a high quality
computer radio system with 120 degree eCCPM mixing. The radio system should have at least 6 chan-
nels to use modern heading lock gyros, Standard servos can be used with a specialized high speed tail
servo.
Warning
This radio controlled model is not a toy! It is a precision machine requiring proper assembly and setup to
avoid accidents. It is the responsibility of the owner to operate this product in a safe manner as it can in-
ict serious injury otherwise. It is recommended that if you are in doubt of your abilities, seek assistance
from experienced radio control modelers and associations. As manufacturer, we assume no liability for
the use of this product.
Pre-assembly Information
Upon opening the kit, all components are in individual bags. Please thoroughly read through this manual
before attempting assembly. Some specialized tools are recommended but not required for full assembly.
Be careful when opening each bag as not to lose any hardware. As a reminder, all metal to metal screw
assemblies require “blue” thread lock compound, all metal to plastic screw assemblies require slow set-
ting CA and all bearing race to metal shafts should use “red” thread lock compound.

2. Battery Warnings & Safety
For Lithium Polymer and NiMH/NiCD cell or battery packs purchased.
1. Never fast-charge any battery type unattended.
2. Never charge Li-Poly cells or battery packs at any rate unattended.
3. Only charge Li-Poly cells or battery packs with a charger designed specically for lithium polymer chemistry.
4. Li-Poly cells can ignite because of unmatched cell capacity or voltage, cell damage, charger failure, incorrect
charger setting and other factors.
5. Always use the correct charging voltage. Li-Poly cells or battery packs may ignite if connected to a charger
supplying more than 5 volts per cell.
6. Always assure the charger is working properly.
7. Always charge Li-Poly cells or battery packs where no harm can result, no matter what happens. We suggest a
brick box or likeness. Have sand handy in a bucket for any need to extinguish any re. NEVER use water on any
cells or battery packs.
8. Never charge a cell or battery pack in a model. A hot pack may ignite wood, foam, plastic, etc.
9. Never charge a cell or battery pack inside a motor vehicle or in a vehicle’s engine compartment.
10. Never charge a cell or battery pack on a wooden workbench or on any ammable material.
11. If a cell or battery pack is involved in a crash:
a. Remove the cell or battery pack from model.
b. Carefully inspect the cell or battery pack for shorts in the wiring or connections. If in doubt, cut all wires from cell
or battery pack.
c. Disassemble the pack
d. Inspect cells for dents, cracks and splits. Dispose of damaged cells.
12. Dispose of cells or battery packs as follows:
a. Discharge: with the cells or battery pack in a safe area, connect a moderate resistance across the terminals until
the cell or battery pack is discharged. CAUTION: cell or battery pack may be hot.
b. Discard:
i. NiMH: place in regular trash
ii. NiCD: recycle (cadmium is toxic)
iii. Li-Poly: puncture plastic envelope, immerse in salt water for several hours and place in regular trash.
13. Handle all cells or battery packs with care, as they can deliver high currents if shorted. Shorting by a wedding ring,
for example, will remove a nger.
14. Always store cells or battery packs in a secure location where they cannot be shorted or handled by children.
15. When constructing a battery pack, always use cells of the same capacity (mAh)
16. DO NOT store fully charged or discharged batteries in your helicopter.
17. When cutting wires, always cut ONLY ONE WIRE AT A TIME.

1) Align the mounting posts from the front transmission
gearbox with the mounting posts at the rear of the main
frame. The horizontal n on the tail boom facing should
face up so the rudder pushrod and tail boom support struts
hang below the tail boom.
2) Using the hardware provided attach the tail section to
the frame section. Do not fully tighten the screws till
the following step.
1) Align the transmission gear mesh before fully
tightening the screws holding the frame and tail sections.
Good alignment is smooth and free of resistance without
slipping or skipping teeth. (HINT:) place a strip of paper
between the gears to give proper clearance. Turn the
main gear while feeding the strip of paper between
through the gears. If the strip of paper comes out torn,
then the gear mesh is too tight. If the strip of paper
comes out not matching the obvious accordion pattern
from the gears’ teeth, then the gear mesh is too loose.
2) Attach the tail boom support struts to the horizontal n
clamp and the rear mounting posts on the landing struts
as shown by tightening the four set screws. (HINT:) To
help prevent rotation of the horizontal n mount, wrap the
area under the horizontal n mount with a few layers of
electrical tape.

1) Before proceeding to measure and install the
pushrods, make sure you have adjusted the
ybar to it’s optimal level (ybar paddles at and
parallel to the ground). Adjust the ybar until
the outer at spots align with the set screws
in the ybar control arms (set screws facing
upward and ybar control arms are ush up
against the seesaw).
2) Make certain that the ybar is equal in length
on both sides of the rotor head before tighten-
ing the ybar control arms. Set the ybar control
arms ush and level to the seesaw and tighten
the set screws using locktite.
It is very important that before you install the
pushrod linkages that your transmitter’s bat-
teries are fully charged. Then remove all the
servo horns from the servos and center all the
mechanical or electronic trims on the radio.
Due to the different types of radio and servos
that are chosen to install into the helicopter,
match each pushrod to the lengths in the table
for optimum setup.
Note: All dimensions are in millimeters and
are measured from the centers of the con-
trol balls or ball ends.

There are three servos that are mounted on the left and right main frames. They work together to tilt the swashplate
producing the collective pitch, roll cyclic pitch (aileron control) and the fore-aft cyclic pitch (elevator control). Before be-
ginning this section you should center all servos using the radio. All servo arms must be set with linkages as pictured at
90 degree angles. All servos mount with M2.5x12 self tapping screws, M2 servo balls and M2 Nuts. IMPORTANT:
Century logo on all ball links must face OUTWARD as pictured.
The pitch servo will mount with a full servo arm on the
lower opening of the left side of the main frame. The dis-
tance between the steel balls (center of ball) on the servo
arm should be 25mm. Use the 4 servo screws and 2 servo
mounting tabs to mount the pitch servo with the servo arm
further toward the rear of the frame (pictured above).
Place two servo balls on to the pitch servo arm facing
inside toward the frame. Attach 2 of the 49mm linkages to
the servo arm balls then to the balls on the pitch bellcrank.
Use the 4 servo screws and 2 servo mounting tabs to
mount the elevator servo with the servo arm output fac-
ing toward the front inside of the frame (pictured above).
The distance from the center of the servo to the center of
the ball on the servo arm should be between 20-22mm
Place one servo ball to the pitch servo arm facing in-
side toward the frame. Attach two 50mm linkage to the
servo arm ball then to the balls on the elevator bellcrank
(CNE581).

The aileron servo will mount with a full servo arm on the lower
opening of the right side of the main frame. The distance be-
tween the steel balls (center of ball) on the servo arm should
be 12.5mm. Use the 4 servo screws and 2 servo mounting
tabs to mount the aileron servo with the servo arm further
toward the rear of the frame (pictured above).
Place two servo balls to the aileron servo arm facing inside
toward the frame. Attach 2 of the 49mm linkages to the servo
arm balls then to the balls on the aileron bellcrank.
Move the collective stick to its maximum position and watch
for any roll (aileron) or pitch (elevator) inputs. If an input is
found, the problem will be one of the following in the table.
The table describes the symptom and the steps to correct
them.

CCPM Servo Guidelines
8. Installing and Adjusting Control Components
The goal in the end after all the servos are mounted is to have the swashplate sit level or at 90 degrees to the main shaft and
have the swashplate move equally fore, aft and side to side. The swashplate will also travel up and down as the three servos
work together. This will result if the previous instructions have been followed and the ATV function for the three CCPM servos
has been set very, very accurately to eliminate pitch change when moving the aileron or elevator sticks.

The Rudder Servo Pushrod changes the pitch of the tail ro-
tor blades to increase or decrease the torque compensation to
rotate the nose of the helicopter about the main shaft.
Use a servo horn in the shape of a cross and trim the 3 of the 4
arms off. The Rudder Servo Pushrod has a preset length from
the factory. Use the 4 Servo screws and 2 servo mounting tabs
to mount the servo with the servo output facing the forward right
side of the helicopter (pictured to the right). At this point, turn
on your radio equipment to center the rudder servo. Attach the
servo horn at 90 degrees aligned with the servo.
Use a servo ball on the outside of the servo arm. Attach the front
end of the rudder control rod to the servo ball.
