INTRODUCTION

TABLE OF CONTENTS

3

For any helicopter to perform to its full potential, it must be
equipped with all the right gear (servos, batteries, receiver , etc).
While other brands of equipment can be used, the equipment
we recommend has the advantage of being extensively tested
and proven effective. If you assemble this model according to
this manual and use the recommended equipment, you should
get top performance from your Kinetic .50.

We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club.The AMA is the governing body of model
aviation and membership is required to fly at AMA clubs.
Though joining the AMA provides many benefits, one of the
primary reasons to join is liability protection. Coverage is not
limited to flying at contests or on the club field. It even applies
to flying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way .There are over 2,500
AMA chartered clubs across the countr y.Contact the AMA at
the address or toll-free phone number below.

Failure to follow these safety precautions may result in
severe injury to yourself and others.

• Keep your face and body as well as all spectators away
from the plane of rotation of the rotors.

• Keep these items away from the rotors: loose clothing
(includes ties, scarfs and shirt sleeves), long hair, and
loose objects (such as pencils, screwdrivers) which can f all
from shirt or jacket pockets.

• The spinning blades of a model helicopter can cause
serious injury. Main rotor blades are consumable items,
please inspect blades before flight.

• When choosing a flying site for your Kinetic .50, stay clear
of buildings, trees and power lines.

• AVOID flying in or near crowded areas. DO NOT fly close
to other people, children or pets.

• Maintain a safe pilot-to-helicopter distance while flying.

• Your Kinetic .50 should not be considered a toy, but rather
a sophisticated, working model that functions very much
like a full-size helicopter. Because of its performance
capabilities, the Kinetic .50, if not assembled and operated
correctly, could possibly cause serious injury to you or
spectators and damage to property.

• You must assemble the model according to the
instructions. Do not alter or modify the model, as doing
so may result in an unsafe or unflyable model. In a few
cases the instructions may differ slightly from the photos.
In those instances, the written instructions should be
considered as correct.

• You must take time to build properly, true and strong.

• You must use an R/C radio system that is in first-class
condition and a correctly sized engine and components
throughout the building process.

• You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air .

• You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
linkages or other connectors often and replace them if they
show any signs of wear or fatigue.

• If you are not an experienced pilot or have not flown this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for y our
first flights. If you’re not a member of a club, your local
hobby shop has information about clubs in your area
whose membership includes experienced pilots.

SAFETY PRECAUTIONS

Two of the most important things you can do to
preserve the radio controlled aircraft hobby are to
avoid flying near full-scale aircraft and avoid flying

near or over groups of people.

AMA

CAUTION: Be aware that the Kinetic .50 is

operated on the same frequency band as most R/C
models. If flying your helicopter within five miles of an
R/C site, there is a real possibility that you could be
operating your model on the same frequency (channel)
as another R/C pilot. If this happens, a crash will
result—with the person flying the more expensive
model suffering the greater loss (and having greater
potential for property damage or injury). The best thing
to do is to join an R/C club and fly at the site where
frequency control measures will be in effect.If you insist
on flying elsewhere, always be aware of your proximity

to R/C flying sites.

Remember: Take your time and follow the instructions
to build a safe and enjoyable model.

This is a partial list of items required to finish the Kinetic .50
that may require planning or decision making before starting
to build. Order numbers are provided in parentheses.

The Kinetic .50 requires five servos.The cyclics, throttle and
collective require a minimum of 42 oz/in for basic aerobatics.
A Hi-Speed and Hi-Torque tail servo such as the (FUTM0224)
Futaba®DS9254 is highly recommended to obtain the best
performance from the gyro.

A 6-channel transmitter is required to fly the Kinetic .50.
Modern computer radios make adjustments considerably
easier and are highly recommended. Plus the features on
the radios today make 3D maneuvers possible.

ADDITIONAL ITEMS REQUIRED

DECISIONS YOU MUST MAKE

We, as the manufacturer, provide you with a
top quality, thoroughly tested ARF and instructions,
but ultimately the quality and flyability of your finished
model depends on how you build it; therefore, we
cannot in any way guar antee the performance of your
completed model, and no representations are
expressed or implied as to the performance or safety

of your completed model.

• There are two types of threaded fasteners used in this kit:
Self-T apping Screwsare designated by a diameter and
a length and are intended to thread into plastic.

This is a 3mm x 10mm Self-Tapping

Machine screws are designated by a diameter and
threads per mm/inch. This type of screw is referred to as
Socket Head Cap Screw (SHCS) through out this man ual.

This is a 3mm x 10mm SHCS

• Thread Locker: Model engines generate a lot of vibration

and cause screws to work loose.Thread Locker (GPMR6060)
should be used on all machine screws when they are
threaded into a pre-tapped hole in metal. Generally blue
thread locker is removable and should be used in all cases.
Please keep in mind only a small amount of thread locker is
needed to retain the bolt. Please check preassembled
components for thread locking compound.

• Ball Links: If you look closely at the

plastic ball links used on this helicopter
you will notice the holes on each side of
the link are different sizes.The side with
the smaller hole also has writing on it as shown above.
When you snap the link on, make sure the writing is to
the outside. If you accidentally snap the small side on
first, the ball link may crack. If the ball link does not pivot
freely once snapped on, you can use a small pair of pliers
to lightly squeeze the link and help loosen it up.

• When you see the term

test fit

in the instructions, it means
that you should first position the part on the assembly to
verify it fits properly. Once you are sure, then proceed with
the instructions or assembly.

• Photos and sketches are placed before the step they
refer to .Frequently you can study photos in following steps
to get another view of the same parts.

Before starting to build, take an inventory of the model to
make sure it is complete, and inspect the parts to make sure
they are of acceptable quality. If any parts are missing or are
not of acceptable quality, or if you need assistance with
assembly, contact Product Support.When reporting defective
or missing parts, use the part names exactly as they are
written in the Kit Contents list.

SET MODULATION TYPE

6EXH

7CH

9CH

Most computer radios are capable of transmitting in FM/PPM
or PCM. Depending on your radio and receiver, you must set
the modulation type in the radio. If the modulation type is
wrong, the receiver and servos will not operate at all. If you
are having problems, this is the first thing to check.

Once the modulation type is changed, it is necessary to
power down and power up again before the change will take
effect. Futaba radios also keep the modulation type in
memory for each model. If the modulation changes from
model to model, then the transmitter must be powered down
and up again before the controls will work.

❏ Futaba T6EXH:Select the [MODL] menu and press (Select)

button twice.The screen should now show [PULS] [PPM/PCM].

EXPONENTIAL

Exponential should be used to soften the control feel around
center. Futaba radios use a “–” percentage to soften the
sensitivity.Please read your transmitter’s instruction manual
to determine if “–” or “+”e xponential should be used.Futaba
users should start out with –30% exponential on the
following controls: Forward and Aft cyclic, Left and Right
cyclic, and Tail Rotor.

Most radios allow you to set the e xponential f or low and high
rates independently; you should set both rates to the same
value in case you accidentally have the dual rate switched
on. Dual rates are not needed on the Kinetic .50. If you still
feel the model is too sensitive, increase the exponential %
until you are satisfied with the overall feel.

SUB-TRIM

If possible, sub-trim should be avoided.Most servo arms are
designed with an odd number of splines which allows you to
rotate it 90° or 180° and change the center position of the
arm. If you cannot get the arm perfectly straight, then a
small % of sub-trim may be used but it is best to a v oid using
it. Sub-trim can decrease the available throw one direction.

FAIL-SAFE

6EXH

7CH

9CH

This function is only available for PCM receivers and cannot
be used on FM.What fail-safe provides is a set of commands
for the servos to follow if the receiver should experience
interference for more than two seconds. Please set the
throttle [FAIL SAFE] to bring the engine back to idle and
leave all other servos set to [HOLD].This will help to prevent
damage in the case of severe interference.

SERVO SETUP AND LINKAGES

Most servo arms have an odd number of splines, which
allows you to rotate it 90°, 180° or 270° to help with the
centering. All servo arms should be perpendicular to the
servos when installed in the Kinetic .50.

FORWARD/AFT CYCLIC SETUP

❏ 1. Turn on the transmitter and receiver and center the

sticks.Test fit a servo arm onto the ser vo.The arm must be
perpendicular to the servo, as shown above. (If the ar m isn’t
perfectly aligned, rotate it 90° and recheck alignment.Repeat
until 90° alignment is achieved.)

❏ 2. Remove the arm and using a pair of wire cutters, clip

off the three unused sides. Install a metal control ball into

the servo arm at 10.5mm from center (second hole out from
center on Futaba arms). Using thread locker, install the
2mm nut onto the back side of the servo arm and tighten.

❏ 3. Verify the servo arm clears the left/right cyclic servo.If

MAIN BLADES
Warning: The blade root reinforcements must be glued to
the main blades. Please inspect the blades for damage

before assembling them.Do not exceed 1700 RPM with the
wood blades or failure may occur. Blades are considered
consumable items and should be discarded if there is any
sign of damage.

❏ 1. Position the blade as shown above and test fit the top

reinforcement on the blade.

❏ 2.T urn ov er the blade and test fit the bottom reinf orcement.

HEAD AND LINKAGES

❏ 3. Once you have verified everything fits properly, mix up

some 30-minute epoxy and apply it to the exposed wood on
the root of the blade.Install the top and bottom reinforcements
as shown above. Double check your work to verify the
reinforcements are installed properly. Install and tighten the
two 2.6mm screws into the reinforcements as shown.

❏ 4. Use a paper towel dampened with isopropyl alcohol to

remove the e xcess glue from the blade.Before the epoxy sets,
install the blades into the grips to clamp the reinforcements
down onto the blade.Once the epoxy has set, you can proceed
to the next step.

❏ 5. Using the 4mm bolts and nylon lock nuts, install the

blades into the grips as shown.

BLADE BALANCING
Note: All main blades must be balanced before use. We

recommend using the Heli-Max Blade Balancer (HMXE4855).

❏ 1. Apply the two colored stripe decals to the tips of your

main rotor blades (for use in blade tracking later on).

❏ 2. Prepare the balancer for use by rotating the brass

adjustment dial until the bubble in the vial indicates level. Make
sure that the blade balancer does not move during this process.

❏ 3. Place one blade onto the balancer with the leading

edge against the side with the level. Shift the blade on the
balancer until the bubble indicates level. The middle of the
black balancing tray is now at the C.G. of this blade. Mark
this position on the blade with a felt tip pen.

❏ 4.Line up the ends of both blades.Transfer the mark you

made on the first blade to the second blade.

28

❏ 5.Position the second blade on the tray, with the mark at

the center.Add balancing or electrical tape to the lighter end
until the bubble indicates that both sides are level.The C.G.
of both blades is now matched. If the tape ends overlap,
make sure the overlapping end points to the

trailing

edge of

the blade.

❏ 6. Your Heli-Max Blade Balancer includes four sizes of

blade mounting plates and a nylon mounting bolt.Select the
mounting plate that best fits the holes in the blade grips.
Secure the mounting plate and two blades to the balancer
with the nylon mounting bolt.

❏ 7.Add tape to the C.G.of the lighter blade until the bubble

level indicates that the two blades balance.Using a different
tape color in this step will remind you that future
adjustments will require both balancing steps.

PITCH CURVES

❏ 1.The pitch gauge is used by setting the desired pitch on the

gauge and adjusting the blade pitch until the top (or bottom) of
the gauge is parallel with the flybar.Make sure the flybar is level
while doing this.If y ou need to make an adjustment to the pitch
of the blades, then adjust the long linkages that connect the
swashplate to the mix er arm.The goal is to have positive 10° at
full throttle/collective and negative 10° at low throttle/collective.
Then use the pitch curves within the radio to adjust the
collective pitch range.

Warning: Beginners should use a maximum negative 2° collective with the throttle stick at idle. It helps to reduce the
sensitivity of the collective and prevents hard landings when the throttle is brought back to idle.Later, once you advance and
need more negative collective, simply make adjustments in the transmitter

.

❏ 2. Tur n on the transmitter and receiver.Move the collective

stick to full throttle. Place the pitch gauge on the blade as
shown and set it to +10°.Align the top (or bottom) of the pitch
gauge with the flybar. If necessary, adjust the long linkage
between the mixer and the s w ashplate .Once the correct pitch
has been established, adjust the length of the linkage on the
opposite side to match.

❏ 3. On your transmitter, place the throttle/collective stick in

the center.Verify that the setting is around +4.5°.If the pitch is
off, adjust P oint #3 in the pitch curve on your radio .If you adjust
Point #3, adjust Points #2 and #4 to maintain a smooth curve.

❏ 4. Lower the throttle/collective stick on the transmitter to

the bottom. Verify that the setting is around –2°. Use pitch
curve Point #1 if adjustments are needed. Once you are
finished, set Point #2 to keep an even curve.

❏ 5. Repeat the pitch curve setup for the Hold function and

any other Idle Ups you may need.

FUEL LINES

❏ Cut a piece of 4" [102mm] fuel line for the carburetor

pickup line and install. Use the remaining fuel line for the
pressure line to the muffler.

MUFFLER INSTALLATION

❏ Install your muffler f ollowing the man ufacturer’ s instructions.

Mounting hardware should be included with the muffler.

BODY AND MOUNTS

❏ 1. Slide the threaded rod through the frame.Using thead

locking compound, install the body mounts as shown abov e.

FINAL ASSEMBLY

30

31

❏ 2.T rim the front of the body as shown abo ve .Make a clean

cut by making several passes with a hobby knife. Mark the
body 5/8" [16mm] up from the back edge and 5/8" [16mm]
right. Drill 1/4" [6.4mm] holes for the rubber grommets.Install
the grommets into the body.

❏ 3. Install the front body clamp using two 3x8mm self-

tapping screws. Please note that the wider end should face
the back of the canopy.

❏ 4. Depending on your muffler, it may be necessary to cut

the body for clearance.Leave at least 1/4" [6.4mm] between
the body and muffler.Mount the body by sliding the canopy
latch onto the “L” bracket on the servo tray. Lift up the back
portion of the body and push the grommets onto the rear
body mounts.

❏ 5. Once the body is installed, trim and test fit the

windshield. When satisfied with the fit, drill 1/16" [1.5mm]
holes at the locations shown and use 2x3mm self-tapping
screw to attach the windshield. Repeat for the other side of
the body.

DECALS

❏ Clean the body thoroughly with glass cleaner to remove

any mold release left over from manuf acturing.Spraying glass
cleaner on the body before applying the decals enables you
to reposition them until they are perfectly placed. Once in
place, use a squeegee to remove the cleaner, allowing the
decals to “stick”in place.

CHECK THE CONTROL DIRECTIONS

Turn on the transmitter and allow the gyro 5 seconds to
initialize before moving the helicopter or oper ating the sticks .If
everything has been adjusted properly the swashplate should
be level with the main frame when the sticks are centered.

Forward Cyclic

❏ Look at the helicopter from the right side. Push the right

stick forward.The swashplate should tilt forward as shown.

Aft Cyclic

❏ Pulling the right stick back should make the swashplate

tilt backwards.

Left Cyclic

❏ View the helicopter from the rear. Pushing the right stick

to the left should make the swashplate tilt to the left.

Right Cyclic

❏ Continue to view the helicopter from the rear. Pushing

the right stick to the right should make the swashplate tilt to
the right.

Ascend Collective

PREPARE FOR FLIGHT

32

33

❏ When the left (collective) stick is pushed forward, the

swashplate should move up and the carburetor should open.

Descend Collective

❏ When the left (collective) stick is pulled backward, the

swashplate should mov e down and the carb uretor should close.

Left T ail Rotor

❏ When the left (tail rotor) stick is moved to the left, the tail

pitch slider should move to the right as shown.

Right T ail Rotor

❏ When the left (tail rotor) stick is mov ed to the right, the tail

pitch slider should move to the left as shown.

Gyro Compensation Direction

❏ Pick the helicopter up by the main shaft and rotate the nose

to the left (counterclockwise).The gyro should compensate by
moving the tail rotor pitch slider to the left (toward the tail
boom). If the pitch slider moves right instead, change the
reversing switch for the servo.

RANGE CHECK

Ground check the range of your radio before the first flight of
the day. With the transmitter antenna collapsed and the
receiver and transmitter “ON”, you should be able to walk at
least 100 feet awa y from the model and still ha ve control.Have
an assistant stand by your model and tell you what the servos
are doing while you work the controls. If the controls do not
respond correctly , do not fly! Find and correct the prob lem first.
Look for loose servo connections or broken wires, corroded
wires on old servo connectors, poor solder joints in your
battery pack or a defective cell, or a damaged receiv er crystal
from a previous crash. Failure to follow these safety
precautions may result in severe injury to you and others.
Keep yourself and all spectators away from the plane of
rotation of the rotors. Keep these items away from the rotors:
loose clothing (shirt sleeves, ties, scarfs), long hair, or loose
objects (such as pencils or screwdrivers) that may fall out of
shirt or jacket pockets into the rotors.The spinning blades of a
model helicopter can cause serious injury.When choosing a
flying site for your model, stay clear of buildings, trees and
power lines.AVOID flying in or near crowded areas.DO NOT
fly close to people, children or pets. Maintain a safe pilot-to­helicopter distance while flying.

BALANCE THE MODEL (C.G.)

The Kinetic .50 should balance level when picked up by the
flybar with the flybar perpendicular to the tail boom. If the tail
drops, the helicopter is tail heavy and you need to add
weight to the front or if possible move equipment forward. If
the nose drops, you need to add some weight to the tail of
the helicopter or move equipment back as needed.

The C.G. on a model helicopter is not as critical as it is on
model airplanes, but can cause some trim problems as you
learn to fly .If nose weight is needed, consider using a larger
capacity battery.

At this stage, the model should be in ready-to-fly condition.

IDENTIFY Y OUR MODEL

Whether you fly at an AMA sanctioned R/C club site or
somewhere on your own, y ou should alwa ys hav e y our name,
address, telephone number and AMA number on or inside
your model.It is required at all AMA R/C club flying sites and
AMA sanctioned flying events .Fill out the identification tag on
page 38 and place it on or inside your model.

CHARGE THE BA TTERIES

Follow the battery charging instructions that came with your
radio control system. You should always charge your
transmitter and receiver batteries the night before y ou go flying,
and at other times recommended by the radio manufacturer.

Read and abide by the following e xcerpts from the Academy
of Model Aeronautics Safety Code.For the complete Safety
Code, refer to

Model Aviation

magazine, the AMA web site

or the Code that came with your AMA license.

GENERAL

1) I will not fly my model aircraft in sanctioned events, air

shows, or model flying demonstrations until it has been
proven to be airworthy by having been previously,
successfully flight tested.

2) I will not fly my model aircraft higher than approximately

400 feet within 3 miles of an airport without notifying the
airpor t operator. I will give right-of-way and avoid flying in
the proximity of full-scale aircraft. Where necessar y, an
observer shall be utilized to supervise flying to avoid
having models fly in the proximity of full-scale aircraft.

3) Where established, I will abide by the safety rules for the

flying site I use, and I will not willfully and deliberately fly my
models in a careless, reckless and/or dangerous manner.

5) I will not fly my model unless it is identified with my name

and address or AMA number, on or in the model. Note:
This does not apply to models while being flown indoors.

7) I will not operate models with pyrotechnics (any device

that explodes, burns, or propels a projectile of any kind).

RADIO CONTROL

1) I will have completed a successful radio equipment ground

check before the first flight of a new or repaired model.

2) I will not fly my model aircraft in the presence of spectators

until I become a qualified flier, unless assisted by an
experienced helper.

3) At all flying sites a straight or curved line(s) must be

established in front of which all flying takes place with the
other side for spectators. Only personnel involved with
flying the aircraft are allowed at or in the front of the flight
line. Intentional flying behind the flight line is prohibited.

4) I will operate my model using only radio control

frequencies currently allowed by the Federal
Communications Commission.

5) I will not knowingly operate my model within three miles

of any pre-existing flying site except in accordance with
the frequency sharing agreement listed [in the complete
AMA Safety Code].

9) Under no circumstances may a pilot or other person

touch a powered model in flight; nor should any part of
the model other than the landing gear, intentionally touch
the ground, except while landing.

PREFLIGHT

34

35

Please try to find a local club (check www.modelaircraft.orgfor
listings) or find an experienced modeler for help before starting
to fly. There are a lot of mistakes that can be made during the
assembly of helicopters that an experienced modeler can catch.
They will help you get the model setup properly and verify that
the model is trimmed out and ready for your first flight.

The web sites listed below are discussion forums for R/C
Helicopters and Planes.There is a lot of information available
on the forums.

www.rcgroups.com

www.rcuniverse.com

www.runryder.com

Computer flight simulators are excellent practice bef ore risking
your model.Great Planes RealFlight®G3.5 (GPMZ4405) is the
most realistic simulator available and is highly recommended.

CONTROLS

Shown below are the controls available on the Heli-Max
Kinetic .50 and how they operate during flight.

Forward Cyclic

Moving the right (cyclic) stick forward causes the helicopter
to lean forward and start moving forward.

Aft Cyclic

Moving the right (cyclic) stick backward causes the helicopter
to lean backward and start moving backward.

Left Cyclic

Moving the right (cyclic) stick to the left causes the helicopter
to lean left and start moving in that direction.

Right Cyclic

Moving the right (cyclic) stick to the right causes the helicopter
to lean right and start moving in that direction.

Ascend Collective

When the left (collective) stick is mov ed f orward, the helicopter
will ascend.

FLYING

Descend Collective

When the left (collective) stick is moved downward, the
helicopter will descend.

Left T ail Rotor

When the left (tail rotor) stick is moved to the left, the
nose of the helicopter will move left and the helicopter will
rotate counterclockwise.

Right T ail Rotor

When the left (tail rotor) stick is moved to the right, the
nose of the helicopter will move right and the helicopter will
rotate clockwise.

TRAINING GEAR

If you have ne v er flown a helicopter bef ore, consider purchasing
training gear.It not only helps prevent crashes and tip-ov ers, b ut
prevents damage b y softening not-so-perfect landings.The Heli­Max Training Gear (HMXE2025) is highly recommended.

FLYING CONDITIONS

During your first flight, it is very helpful to fly in light winds and
have a helper to keep an e y e on things around you.If you are
flying off grass, make sure it is cut low. This will allow the
helicopter to slide around without catching. Finally, make
sure there are no obstacles or distractions in your flying area.

BEFORE EACH FLIGHT

Please inspect the model for loose or damaged parts.
Inspect the main rotor blades and ball links. Make sure you
have selected the proper model in the transmitter and all of
the controls operate in the correct direction.

ST ARTING THE MODEL

Set the engine’s needle valve to the recommended factory
setting. Please review the manufacturer’s operating
instructions for the engine.

If you are flying at a club, be sure y ou use their frequency control
system.T urn on the radio first and select the correct model.Turn
on the helicopter next. Allow the gyro to initialize for at least 5
seconds before moving the model or using the transmitter.

Fill the fuel tank. Make sure the idle up switch on the
transmitter is set to normal mode and the throttle is at idle.
Check the throttle arm on the engine to verify it is at idle.

Attach the glow igniter to the glow plug. You must have a
solid hold on the blade grip in case the model starts at a
throttle position other than idle. Use the starter to turn the
engine over. If the engine does not want to start, check the
glow plug by removing it and attaching the glow igniter.
Verify that the needle settings are correct. It is possible the
engine could be flooded. If no problems can be found,
assume the engine is flooded.Remov e the fuel line from the
carburetor and try starting the engine again.

Once the model has been started and has warmed up,
remove the glow igniter. Carr y the model out to the location
where you plan on flying. Place the model on the ground and
walk back at least 30' [or 10m].

ADJUST BLADE TRACKING

If you feel uncomfortable adjusting blade tracking by yourself,
please have a helper do the sighting f or you and simply fly the
model. Slowly bring the main rotor up to speed but do not lift
off the ground. Please wear safety glasses when performing
the next step. Observe whether the rotational planes of the
blades are the same. If they are not, adjust one of the short
double linkages to bring the blades into the same plane.

TAKEOFF

Slowly add power and observe the model. If you feel it
needs trimming at any time, simply lower the collective stick
all the way down to land and adjust the trim on the
transmitter.For now, simply bring the collective stick up until
the helicopter is “light on the skids”. As you become more
comfortable with the helicopter, you can lift higher off the
ground. Stay low until you become comfortable.

If you should get into trouble, simply bring the collective stick
down slowly and the helicopter will settle and land. This is
when the training gear serves its purpose, since it helps to
level the helicopter automatically before landing.The tr aining
gear will also allow the model to slide on most surfaces.

You will notice the cyclic controls lag behind your control
inputs.This is perfectly normal and something you get the feel
for with time.It’s normal to drift around in a hover until you are
used to flying the model.The cyclic controls on the Kinetic .50
are fairly sensitive so only small movements are necessary.

HOVERING

Once the helicopter is hovering, concentrate on holding the
helicopter in one spot. This can take some practice.Wind has
a big effect on the stability of the helicopter .Be patient and take
your time.Trying to rush the learning process can be costly.

LANDING

Level the helicopter into a ho ver and slowly decrease power
until the helicopter settles onto the ground.

BASIC MANEUVERS

Once you have become accustomed to ho vering, it is time to
work on moving the helicopter around.Just pic k some points
on the ground (you can mark the ground if you like) and fly
the helicopter over to them. Tr y to maintain a steady hover
directly over those points. For now, always keep the tail
pointing directly at you.This helps to keep your orientation.

Pirouettes: Add a small amount of tail rotor (left or right) and
try rotating the helicopter slightly sideways and see if you can
maintain the hover. If you get uncomfortable bring the tail
back towards you. Once you begin to feel comfortable, try

moving the helicopter to the side and turning back.Then fly
back to the other side in straight lines.

Once you become comfortable with those you can try
rotating the helicopter 360°, which is called a pirouette.The
helicopter can drift during pirouettes, so make sure you
have plenty of room to perform the maneuver.

After pirouettes, it is time to move onto nose-in ho vering. It is
best to wait for a calm da y.Take off and climb to 15'.Pr actice
half pirouettes, working from tail-in to nose-in hovering.Try to
lengthen the delay between the transitions. As you improve,
you’ll remain nose-in for longer periods of time.

Now it’s time to w ork into basic forward flight.Just take the basic
hovering maneuvers listed above and slowly go out farther and
faster, but always bring the helicopter back after one pass.
Practice controlled slow flight in close as well. The more time
you spend practicing, here the easier things will be later on.

AEROBATICS

When you become comfortable in fast forward flight, you can
slowly progress into aerobatics.Once you are in forward flight,
use the idle up switch to raise the rotor RPM for aerobatics;
this provides the power to fly inverted. Also, in wind, it may be
difficult to descend for a landing without the idle up on.

The first step is chandelles. Fly straight across in front of you
and pull up to a 45° angle.Now at the top, when the helicopter
slows down to a stop, apply some tail rotor to bring the nose
around 180° and continue back down on the 45° angle.

As you progress with the maneuver, you can pull to greater
angles, up to 90 degrees.This would be called a stall tur n.

Loops: Once you are comfortable with chandelles and stall
turns, it’s time to move onto the loop.The key to the loop is
entering with plenty of air speed. Start pulling aft cyclic to
enter the loop. As the model goes inverted at the top, pull
back on the throttle a little bit (towards negative (–)
collective) to help hold altitude. As the model comes back
vertical, add some positive (+) collective to speed. One of
the most common mistakes made on loops is using too
much negative (–) collective at the top of the loop.

Flips: These are a lot easier to perform than they sound.
Start with plenty of altitude. From an upright hover, slowly
add in full forward cyclic.As the model approaches vertical,
bring the collective stick back to center. As the model

continues to fly inverted, you will need to start adding in
negative (–) collective (or pull the collective stick back
towards you) to maintain altitude. As the model transitions
back to vertical, again bring the collective stick back to the
middle and start adding in positive (+) collective as the
model comes back to the upright position.

It is all a matter of timing. The most important thing is to
move the sticks smoothly. If you are too aggressive with the
sticks, the head speed will drop and you will lose power.

Rolls: These are very similar to flips and require proper timing
on the collective.From fast forw ard flight, slowly mov e the stic k
to full right cyclic.As the model approaches knife edge (b lades
vertical), slowly move the collective stick towards 0°. As the
model approaches inverted, you should slowly move the
collective stick towards –5° (to maintain inverted flight). By the
time the model reaches knife edge again, the collective should
be near 0°. Slowly move the collective stick towards +5° to
maintain upright flight. This is a simple maneuver to perform
but one of the most difficult ones to perfect.

Inverted Hovering: Keep in mind flying a helicopter in v erted
is very difficult but can be learned. One of the problems is
three out of four controls are reversed (forward/aft cyclic,
collective and tail rotor).You have to mentally reverse these
while flying.It will take some pr actice.If you have a simulator ,
this is the best place to start.

Perform a half loop and hold the inverted por tion for short
periods of time.As you become accustomed to the re v ersed
controls, you will extend the time you fly inverted. This is
very difficult and will take some time to pick up. Also, make
sure you have plenty of altitude for recovery.

GOOD LUCK AND GREAT FLYING!
