Kit Introduction
Thank you for purchasing the X-Cell Fury 55 by Miniature Aircraft USA. This model is the culmination of
years of designing and manufacturing R/C helicopters. It is designed with the highest standards, and will
provide years of enjoyment. Whether this is your rst R/C model helicopter or you are an advanced R/C
helicopter modeler, the X-Cell Fury 55 is a fantastic choice for a “50 size” model.
R/C Helicopter Safety
A radio controlled model helicopter is not a toy, but rather 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 rening 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 rst 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/yer 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 ying eld. A number of guidelines for safe ight have been
developed by experienced yers and are set down here. It is urged that they be read, understood and followed.
Warning! – Risk of death or serious injury
Remote Control (“R/C”) Helicopters can be dangerous. Inexperienced pilots of R/C Helicopters should be
trained and supervised by experienced operators. All operators should use safety glasses and other appropriate
safety equipment, and exercise necessary precautions when fueling, repairing, maintaining, ying and
storing R/C Helicopters, and when using or storing R/C Helicopter accessories, equipment, fuels, and related
materials. R/C Helicopters should be used only in open areas free of obstacles, and far enough from people to
minimize the possibility of injury from the helicopter or any of its components falling or ying in unexpected
directions.
This helicopter is not a toy, but a complex ying 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 ight 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.
General Guidelines for Safe R/C Helicopter Flight
• Fly only at approved ying elds and obey eld regulations.
• Follow frequency control procedures. Interference can be dangerous to all.
• Know your radio. Check all transmitter functions before each ight.
• Be aware that rotating blades are very dangerous and can cause serious injury.
• Never y near or above spectators or other modelers.
• If you’re a beginner, get help trimming the model rst and ight 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.

• AMA is the voice of its membership, providing liaison with the Federal Aviation Administration, the Federal
Communications Commission, and other government agencies through our national headquarters in Muncie,
Indiana. AMA also works with local governments, zoning boards, and parks departments to promote the
interests of local chartered clubs.
• AMA is an associate member of the National Aeronautic Association. Through NAA, AMA is recognized by
the Fédération Aéronautique Internationale (FAI), the world governing body of all aviation activity, as the
only organization which may direct U.S. participation in international aeromodeling activities.

Important Assembly Tips - PLEASE READ
• Follow the instructions. The methods of construction documented in this manual have been proven to work.
Do not rush the build of your model! You have purchased a world class model helicopter kit, take your
time and realize that the nal result is now up to you. Take the time to fully understand each step, if you are
unsure please contact Miniature Aircraft USA.
• Follow the order of assembly. The instructions have been organized into major sections and have been written
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.
• 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.
• Use thread lock as indicated. Generally, any bolt or screw that threads into a metal part requires thread lock.
Model helicopters are subject to vibration and failing to use thread lock on any non-locking assembly may
result in a part becoming loose or falling off.

Getting Started
Bag 1
Locate bag 1, and the hardware for bag 1. Please take the time to identify the hardware for this bag. Please note that the use of
medium thread locking compound is always required when a part is threaded into metal.
Locate the right main frame side MA128-10, rear canopy mount MA128-61, front canopy mount MA128-62, and two MA0060-1
m3x6 socket bolts. Please refer to Illustration 1a for step. Install the canopy mounts on the outside of the right main frame.
Locate the MA128-55 upper main shaft bearing block, MA128-40 lower main shaft bearing block, two MA128-80 boom clamps,
six MA0061 m3x8 socket bolts, and four MA0060-1 m3x6 socket bolts. Please refer to Illustration 1b for the correct placement of
components in this step. Using the MA0060-1 m3x6 socket bolts, attach the MA128-55 upper main shaft bearing block, but do not
fully tighten the bolts at this time. Using two MA0061 m3x8 socket bolts attach the MA128-40 lower bearing block as shown. the
bolts for the bearing blocks need to remain slightly loose as the bearing blocks will have to be properly aligned in a later step. Using
MA0061 m3x8 socket bolts, attach the MA128-80 boom clamp blocks. Do not fully tighten the upper MA0061 m3x8 socket head
bolts at this time, these will be tightened after the boom is installed in a later step. Go ahead and tighten the lower MA0061 m3x8
socket bolts into the MA128-80 boom clamp blocks now.

Locate the MA128-47 tail rotor drive belt, and the MA128-46 tail rotor drive pulley. Refer to Illustrations 1i.1 and 1i.2 for this step.
Insert the tail rotor drive belt through the boom clamps as shown in the illustrations. Note the orientation of the tail rotor drive belt in
between the two tension pulleys. Place the tail rotor drive pulley on top of the lower bearing block, keeping correct orientation of the
drive belt between the tension pulleys.
Locate the MA128-52 main gear, MA128-49 autorotation hub, MA128-43 main shaft, MA0875-1 main shaft collar, MA0059-1
m2.5x6 socket bolt, four MA0062-2 m3x12 tapered socket bolts, and four MA0019 m3 locknuts. Refer to Illustration 1j for this
step. Start by assembling the autorotation hub to the main gear. The use of Tri-ow oil MA3200-02 is recommended to lubricate
the Torrington bearing in the MA128-49 autorotation hub. Tighten the MA0019 m3 locknuts equally around the hub. Do not use
thread locking compound on lock nuts. Loosely thread the MA0059-1 m2.5x6 socket bolt into the MA0875 main shaft collar.
Carefully slide the entire assembly into the frame above the tail rotor drive pulley. The MA128-43 main shaft is then inserted down
through the bearing blocks. (Note the orientation of the main shaft. The top of the main shaft has a hole all the way through, and the
bottom of the main shaft has a hole that only goes through half way.) Apply light pressure down on the main shaft, while tightening
the MA0059-1 m2.5x6 socket bolt. While tightening this bolt ensure that the collar is pushed up towards the upper main shaft,
eliminating main shaft vertical play.

Locate the “50 size” engine you intend to use, MA128-106 centrifugal clutch, MA128-104 aluminum fan, MA128-102 aluminum
fan hub, MA128-25 fan shroud plate, two MA0597-4 brass spacers, MA128-82 motor mount base, two MA128-83 motor mounts,
two MA0078-5 m4x10 socket bolts, four MA0064-3 m3x6 button head socket bolts, the MA0007 6mm washer, six MA0063 m3x10
socket bolts, four MA0067 m3x14 socket bolts, four MA0003 m3 washers, and two MA0062-2 m3x12 tapered socket head bolts.
Miniature Aircraft USA also recommends the use of a crankshaft locking tool MA3000-34. Refer to Illustration 2c for this step. The
engine you intend to use came with a crankshaft washer, and a crankshaft nut, you WILL use these parts with your Fury 55. Place
the crankshaft washer onto the crankshaft. Slide the aluminum fan hub onto the crankshaft. Slide the MA0007 6mm washer onto
the crank shaft. Install the crankshaft nut onto the crankshaft of the engine. Remove the back plate from the engine, and insert the
crankshaft locking tool. GENTLY tighten the crankshaft nut until it BEGINS to snug down. When the nut is properly “snugged” you
will notice no gap between the aluminum fan hub and the crankshaft washer. You will also notice as the nut is snugged down, there
will be no crankshaft play. It is CRITICAL that this nut is not “cranked down” at this point, as the fan hub will become distorted.
Thread the two MA0063 m3x10 socket bolts into the aluminum fan hub. Place the aluminum fan onto the aluminum fan hub, and
line up the mounting holes. Thread in the four MA0064-3 m3x6 button head socket bolts, attaching the fan to the fan hub. Set the
centrifugal clutch onto the aluminum fan hub, thread the two MA0078-5 m4x10 socket bolts through the clutch and into the fan hub.
Set the engine aside. Use four MA0063 m3x10 socket bolts to attach the MA128-82 motor mount base to the MA128-83 motor
mounts. Please take care to note the correct orientation of these parts as shown in the illustration. Also note that the “dimple” in the
motor mount should be facing “down”. Using two MA0062-2 m3x12 tapered socket head bolts, two MA0597-4 brass spacers, attach
the MA128-25 fan shroud plate to the MA128-82 motor mount base as shown in the illustration. Use four MA0067 m3x14 socket
bolts, and four MA0003 m3 washers, attach the completed engine mount assembly to the engine as shown in the illustration.
