The Heli-Max MX450 is a fully aerobatic-capable helicopter,
offering the performance and flying manners of a 60-sized
machine in a smaller, more con venient pac kage .The MX450 is
fully loaded with precision machined aluminum parts for
smooth control without flexing along with a carbon fiber tail
boom and fin set to keep the MX450 light and more agile.The
recommended power system will give you explosive power off
the ground and more than enough power to do tick tocks,
tornado's, chaos's, and much more.

T ak e care to build straight and true.Misaligned parts will hurt the
helicopter's ability to perform the extreme aerobatics it is
designed for.

For the latest technical updates or manual corrections to
the MX450 visit the Heli-Max web site at

www.bestrc.com/helimax.Open the “Helicopters” link, and

then select the MX450 ARF. If there is new technical
information or changes to this model a “tech notice” box will
appear in the upper left corner of the page.

In the hands of a capable pilot, the MX450 is an impressive
3D performer. But for this helicopter to perform to its full
potential, it must be properly equipped with all the right gear
(servos, batteries, receiver, speed control). There may be
more than one type and brand of radio equipment that can
be used. But based on extensive testing, following is the
equipment we recommend so you can get the most
performance out of your MX450 and assemble it as shown
in this instruction manual.

Transmitter

At a minimum, this helicopter requires the use of a six-channel
helicopter transmitter capable of mixing between the throttle
and collective pitch channels. However, to unleash the full
aerobatic potential of the MX450, you will need a computer
radio capable of at least two sets of throttle and pitch curves.
The Futaba®6EXH radio (FUTK60** or FUTK61**) is an
excellent entry-level radio for use with this helicopter.For more
programming capability, any of Futaba’s higher channel-count
computer helicopter radios will work very well.

Servos

You will need four servos for the MX450.The servos should
weight less than 10 grams apiece, and should have a
minimum torque output of 14 oz-in. A good speed rating is
also important for helicopters, and we recommend that you
choose servos with a speed of 0.12sec/60deg or less. We
recommend the Futaba S3103 (FUTM0037) or S3107
(FUTM0025) for use with this helicopter. Note: The Futaba
S3108 servo will not mount to this helicopter without
modification, and is therefore not recommended.

Receiver

You will need a 6-channel receiver for this helicopter. A
small PCM receiver is strongly recommended for the noise
rejection and failsafe capabilities that PCM offers. We
recommend the Futaba R146iP receiver (FUTL0601) You
will also need a single conversion crystal to use with this
receiver. While most Futaba receivers are sold on high and
low bands, the R146iP is not banded and can use either
high or low band crystals.

Low band (channels 11 – 35) Crystal FUTL62**
High band (channels 36 – 60) Crystal FUTL63**

**Replace the “**” in the order number for the crystals with
the preferred channel number. For example, if you want to
fly on channel 33, order crystal number FUTL6233.

DECISIONS YOU MUST MAKE

CAUTION: Be aware that the MX450 is

operated on the same frequency band as larger R/C
models. If flying your heli 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.

Gyro Recommendation

We recommend the use of a heading-hold gyro with this
helicopter. The Futaba GY240 gyro (FUTM0809) is an
excellent choice.

Battery

The MX450 requires a 1200-2000 mAh 3-cell Lithium-Polymer
(LiPo) battery capable of delivering 15A of current continuously.
We recommend the ElectriFly™11.1V 2100 mAh pack
(GPMP0841).This battery will deliver approximately 7 min utes
of flight time with the recommended motor and speed control.

Motor

You will need a brushless motor capable of handling 15A of
continuous current, and up to 22A in bursts. The motor
should also have a kV rating of 2500-3000 RPM/V for use
with the included pinion. We recommend the ElectriFly
Ammo 28-45-2700kV (GPMG5215).

Speed Control

A 35-Amp or better brushless electronic speed control
(ESC) is required for this helicopter. We recommend the
Heli-Max 40A Brushless ESC (HMXM3004).

Charger

A charger capable of charging 3-cell (11.1V) LiPo batteries
such as the ElectriFly PolyCharge 1-3-cell LiPo charger
(GPMM3010) must be used. If using another charger, it
must be a LiPo charger or hav e a LiPo charge mode.Never
charge LiPo batteries with chargers not intended for LiPo
batteries or chargers on NiMH or NiCd settings.
Overcharging or explosion may result. In addition to the
PolyCharge, the ElectriFly Triton™(GPMM3150) and Accu­Cycle Elite™(HCAP0280) are also suitable chargers.

Battery Charging Leads

Many chargers (including the Triton and Accu-Cycle Elite
listed above) do not include charging leads, but rather have
banana jacks to plug the leads into. If this is the case with
your charger, you will need to purchase a charge lead to
match your battery. For the recommended battery pack, the
correct lead is GPMM3105.

❏ 1.Install the aluminum horizontal stabiliz er and the horizontal

stabilizer bracket onto the tail boom with two 2 x 8mm metal
screws. Do not fully tighten the screws at this time. Be sure to
add a drop of threadlocker to each screw.

❏ 2. Secure two aluminum tail strut ends and the rear frame

spacer to the frames with two 2x10mm machine screws as
shown.Use a drop of threadlocker to secure each screw.

❏ 3. Secure two tail strut ends to the aluminum ho r izontal

stabilizer bracket with 2x8mm metal screws. Use a drop of
threadlocker to secure each screw.

ASSEMBLE THE T AIL

IMPORTANT!

INSPECT Y OUR HELICOPTER

Check all screws on the helicopter for tightness. If any
screws are loose, tighten them before flying. If any
machine screw that threads into a metal part is loose, be
sure to secure it with a drop of threadlocking compound.
This check should include the tail blade grip screws,
which will require removal of the tail rotor blades.

❏ 4. Insert the carbon fiber tail struts into the aluminum strut

ends. Secure each end with a drop of thin CA.

❏ 5. Finalize the position of the horizontal stabilizer brack et,

and tighten the horizontal stabilizer screws to hold the
assembly firmly in place. Do not over tighten. Use a drop of
threadlocker to secure each screw.

❏ 1. Slide the rudder pushrod back through both suppor ts

on the tail boom.

❏ 2. Screw a ball link onto the threaded end of the

rudder pushrod.

❏ 3. Connect the ball link to the ball on the tail rotor pitch

control horn. Check to see that the ball link runs freely on the
ball, and loosen it if necessary using the following Heli-Max Tip .

arm should be completely horizontal with the ball end to the
rear as shown.

❏ 3. Using two plastic ser vo screw nuts, install the pitch

servo as shown. With the pitch servo centered, the servo
arm should be completely horizontal with the ball end to the
rear as shown.

❏ 4. Using two plastic servo screw nuts, install the elevator

servo as shown.With the elevator servo centered, the servo
arm should be completely horizontal with the ball end to the
rear.The output shaft of the ser vo should point towards the
front of the heli.

❏ 5. Using two plastic servo screw nuts, install the rudder

servo as shown. With the rudder servo centered, the servo
arm should be completely horizontal with the ball end up as
shown. The output shaft of the servo should point towards

❏ 6. Locate the 3 control rods and the 6 ball link ends.

1) Pitch (54mm)

2) Elevator (48mm)

3) Aileron (41mm)

All measurements are overall length with the ball links
threaded on to the metal rods.

❏ 7. Install the Aileron control linkage as shown.

❏ 8. Install the Pitch control linkage as shown.

❏ 9. Install the elev ator control linkage as sho wn.Be sure that

the swash plate is le v el with all the control arms and the servos
are horizontal. If they are not, remove and adjust accordingly.

❏ 10. Install the ball link to the rudder control linkage and

snap it on the ball attached to the control arm.

❏ 11. Install the Futaba 401 gyro on the top of the frames

as shown with double sided foam tape. Be sure the surface
is clean to get a good bond.An optional mount (HMXE7921)
is available for a more secure mounting, if desired.

❏ 12.Install the receiver in the bay under the spur gear.Be sure

to keep the receiver towards to rear of the bay as show. Attach
with double sided foam tape or Velcro. Make sure that the
receiver antenna is routed so that it cannot possibly interfere
with the main or tail rotor blades.There are many possible wa ys
to route the antenna, and you may ha ve to try different methods
to get interference-free operation, but it is essential that the
antenna be constrained from contact with the blades

❏ 13. Install the pinion onto the motor, and install the motor

in the helicopter. Be sure to set the gear mesh properly. This
can be done by pushing the pinion and spur together with a strip
of typing paper between them and tightening the motor screws.
The paper can then be removed by turning the gears to eject it.

❏ 14. Install the ESC to the bottom of the frames as shown

with hook and loop material or double sided foam tape.

❏ 1. Check the tail drive belt tension by pressing on one

side of the belt with a screwdriver. With gentle pressure, it
should be possible to push the belt approximately as far as
the picture shows. If you can easily push the belt against
itself, it is too loose.If it does not deflect easily, then it is too
tight.If y ou need to adjust the belt tension, simply loosen the
screws shown and slide the tail boom in or out. When you
have the tension correct, retighten the screws. Recheck the
rudder pushrod adjustment.

❏ 2. Attach the hook side of hook and loop fastener to the

battery tray.

FINAL ASSEMBLY & SETUP

❏ 3.Cut the window out of the canop y, and trim the flashing

from around the rear opening.

❏ 4. Cut the clear shield out along the molded-in cut lines.

❏ 5. Secure the shield to the canopy with the two small

screws packaged with the shield.

❏ 6. Install the canopy onto the helicopter.

❏ 7. Apply decals as desired.

8

❏ 1. Attach the “loop” side of the hook-and-loop material to

the battery. Mount the batter y to the batter y tray.

❏ 2. For safety, do not install the main blades while

performing bench setup.

❏ 3. Lower the throttle stick all the way and turn on the

transmitter.Connect your battery to the ESC. If the ESC has
a BEC switch, turn it on.

❏ 4. Check all the servos to see if they are centered. Since

you set the center points as you set up the linkages, they
should already be very close. Use the trims or subtr ims on
the transmitter to center the controls.

❏ 5. Make certain that the swash plate and the motor

respond in the correct direction as shown in the diagram.To
operate the motor, you may have to “arm” your ESC. Follow
the instructions that came with your ESC to do this.If any of
the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected
to those controls. Be certain the servos have remained
centered. Adjust if necessary.

❏ 1. Balance your main blades using the Heli-Max Blade

Balancer (HMXR4855). Do so according to the instructions
that came with your balancer.

❏ 2. Attach the main rotor blades. The blades should be

tight enough in the grips to hold their position when moved,
but still move easily by hand.

❏ 1. Cut out the pitch template from the last page of this

manual and slip it over one of the main blades.

❏ 2.We recommend 8 degrees of maximum collective pitch in

both directions as a starting point. Check to see that the bottom
of the pitch template is level with the flybar at maximum positiv e
pitch and the top of the template is level with the flybar at full
negative collective pitch.Adjust your linkages or radio endpoints
if necessary to achieve these values.

❏ 3. Once you are comfortable with the helicopter, feel free to

increase or decrease this pitch value to suit your flying style.

WARNING: Disconnect the motor from the ESC to prevent
accidental startup while performing pitch adjustment.

To set rates on the elevator and aileron, check to see that the
control rates are set to maximum for high rates. This can be
verified by checking that the ball link attached to the seesaw is
close to touching the main rotor grips at full input. Check the
elevator rate with the flybar perpendicular to the tailboom, and
check the aileron rate with the flybar parallel to the tailboom.
These maximum deflections work well for high rates, and we
recommend 60% of these values for low rates.

Rudder control throw will be affected by your gyro settings,
and will need to be tuned to suit your flying style.

❏ 1. Apply the two different colored stripe decals to the tips

of your main rotor blades.

❏ 2. At zero pitch, bring the main rotor up to speed and

observe whether the rotational planes of the blades are the
same.If they are not, adjust one of the linkages to bring the
blades into the same plane.

Ground check the operational 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 50 feet away from the model and still have control.Have
an assistant stand by your model and, while you work the
controls, tell you what the servos are doing. Repeat this test
with the motor running at various speeds. If the control
surfaces do not respond correctly, do not fly! Find and correct
the problem 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
receiver crystal from a previous crash.

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

Keep your f ace and body as well as all spectators a wa y from
the plane of rotation of the rotors whenever the battery
is connected.

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 MX450,
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-to-helicopter distance
while flying.
