9?s 80-inch giant-scale-legal P-51D Mustang 150 ARF is a
full-throttle scale flying experience perfectly suited for large-scale
modelers. The model features UltraTract metal retracts with struts,
scale flaps, authentic UltraCote trim scheme and other prototypical
details. The level of exceptional scale detail Hangar 9® has
built into the P-51D is virtually without equal. From the scale
display 4-blade prop and prepainted aluminum spinner all the way
to the molded bombs, Hangar 9 has gone the extra mile to produce
a World War II fighter that looks as if it really could be raiding
Japanese forces in the Pacific theater.

radio system in the P-51D will be the Spektrum DX7. The Spectrum DX7
is a full-range, full-performance Spread Spectrum radio system that
can fly anything from small electrics, to gas-powered IMAC planes, to
turbine jet models, without regard to frequencies or available pins.
The packaging and 108 page manual are top notch! Based upon the JR 7202
midrange sport radio, the 20-model DX7 transmitter is full featured.
It has all the programming capabilities to satisfy the demands of my
P-51D project and the majority of R/C modelers.
DX7 is packed with new features like ServoSync (lower latency), ModelMatch
(prevents flying wrong model), and is compatible with the existing AR6000
receivers. The DX7 package (SPM2710) comes with four powerful 72oz/in
DS821 Digital Sport Servos, a 1500mAh NiMH transmitter battery, 4.8v
1100mAh NiCD receiver battery, Tx/Rx dual wall charger, and On/Off switch
use the DX7?
Full Range Performance
* Glitch-Free / Freq. Pin-Free
* Fastest Response (lowest latency)
* Tested in Electrics, IMAC, and Turbines
My day job as a Systems Engineer has provided me with several decades
of experience with radio communications and spread spectrum technology.
Since we were already utilizing the benefits of spread spectrum techniques
in military and commercial applications, I knew that someday it would
revolutionize the consumer market and find its niche in the R/C industry.
As a result, I was less apprehensive about trying the DX7 in an expensive
application than others in my area have been. Bob Violet Models (BVM)
sells and recommends the DX7 for both electric-powered and turbine-powered
jet applications. In addition to many successful IMAC giant scale applications,
glow and electric helicopter applications, and intense indoor applications
where many transmitters operate within a few feet of each other (e.g.
JR and Great Planes E-fests), I have not seen or heard of any interference
the original DX6 was geared toward smaller electrics and parkflyers
with a slightly limited range and noticeable latency issues, the DX7
provides full performance through increased range, redundant dual-channel
receivers, and increased system speed. The reduced latency (time from
stick movement to servo movement) is now the fastest response time of
any other 72MHz PCM radio on the market.
of requiring a frequency pin to ensure that no one else interferes with
your radio, the DX7 scans all 80 channels at 2.4GHz, finds two that
are free, and locks onto them before enabling the transmitter. The receiver,
which was uniquely ?bound? to the transmitter during the setup
procedure, is turned on first and scans all 80 frequencies as well waiting
to hear the correct binding code (unique for each DX7 transmitter) in
the two channels selected by the transmitter. In this manner, your DX7
transmitter cannot interfere with other radios. Equally important, other
DX7 radios cannot interfere with your radio system.
addition to worry-free automated channel selection, the AR7000 receiver
in the DX7 package has a second smaller receiver attached to a six inch
extension cable. By placing the second receiver 2?-6? away
from and adjacent (90 degrees opposite) to the main receiver, it can
see a different RF environment that may still clearly ?hear?
the transmitter when the main receiver has a signal fade. Further, the
2.4GHz radio system is immune to car ignition noise and other RFI (Radio
Frequency Interference) noises that are commonly created in a much lower
frequency domain. The result of this so-called diversity reception has
proven to be the most bullet-proof, glitch-free performance on the R/C
market today. Spektrum also has longer extension cables available should
you need to mount the two receivers farther apart for added convenience.
when you think the DX7 design is impressive enough, along come new and
innovative features like ModelMatch and ServoSync. A personal pet peeve
of mine is when I successfully launch a plane into the air and then
realize I forgot to change the programmed model on the transmitter.
The elevator, rudder, and throttle all worked fine on my ground test
by I failed to notice that my ailerons were reversed. This scenario
is quite painful and I have done it more than once. The ModelMatch feature
in the DX7 embeds a unique code in the receiver during the binding process
that remembers the user-programmable models name. If the wrong name
is on the screen, the model?s controls simply will not respond.
In addition to saving your pride, or plane, the ModelMatch feature can
prevent stripped servo gears and broken linkages.
is a new feature to the DX7 that re-sequences the data between the transmitter
and receiver based upon the type of mixing you select. This ensures
that the servos working together will receive their direction changes
together resulting in a synchronized movement that allows the control
surface to precisely follow the stick movement without delay. Unlike
the latency seen in the earlier DX6 model, performance demanding pilots
that use quick stick movements will absolutely love the ServoSync feature
and low latency of the DX7.
Hangar 9 P-51D will be well protected with the Spektrum DX7 radio system
and benefit from the fastest stick-to-servo response in the industry.
power system plan for the P-51D is to use the E-flite Power
160 outrunner motor and a Castle Creations Phoenix HV-110 ESC.
This motor/ESC combination will be powered by a 10 to 12 cell
LiPo supply and a 4-blade prop for blazing power and scale authenticity.
The power level will be around 3000 watts on the 16lb airframe
which will provide an awesome 187w/lb!
E-flite Power 160 Outrunner Motor is ideal for 160-size sport
and scale airplanes weighing 12-20 lbs (5.4-9 Kg), 3D airplanes
up to 15 lbs (6.8 Kg), or models requiring up to 2700 watts
of power. All the mounting hardware and mating connectors come
with the motor.
prop adapters mated perfectly with the supplied spinner backplate
of my P-51D. The E-flite Power 160 motor comes with two 12mm
prop adapters so that the motor can be mounted on either side
of a firewall. One is meant to fit over the 8mm drive shaft
and the other is meant to attach to the rotating can.
supplied 5" spinner can be used with either the static
prop display or the real operational prop. It must be cut to
fit the blades so you need to decide which prop to use it for.
Spare spinners can also be purchased at Horizon Hobby for this
model. For my project, I choose to use the spinner for the actual
ago, ESCs were not programmable. You were basically stuck with
the settings that came with the controller. The first programmable
ESCs then used the throttle stick in a series of movements to
configure a few settings like BRAKE ON/OFF, MOTOR TIMING, and
CELL COUNT. Feedback from the setting change was often heard
as a series of beeps from the motor being pulsed at an audible
rate. When the flexibility of changing ESC settings became more
than just a few parameters, the throttle stick method became
complex and cumbersome to use.
the pure pleasure of using the Castle LINK software! The interface
cable can be purchased at Castle Creations and the software
can be downloaded from the Castle Creations Web site. After
connecting the Castle LINK device to my USB port and a single
6s battery to my Phoenix HV110 ESC, I was able to program the
exact settings I wanted into the controller and save the setup
to my computer hard drive.
Two of the Castle LINK features that I found very innovative
were that I could not only update the firmware code in my HV110
ESC but I could reverse the motor direction without changing
the wires between the motor and ESC! This worked out great for
me because I had discovered my motor was spinning clockwise
instead of counter-clockwise. I do not have to remove the cowl,
cut the tywraps, and swap wires. I have heard that some of the
folks flying pattern planes were having Phoenix HV ESC issues
on a 12s LiPo supply and Castle Creations has made some recent
improvements in operation. It is very convenient to simply download
these improvements from the Internet into my P-51D without removing
photos show the default settings for the ESC. Typically, I disable
the brake (Brake Strength = 0%), set the Throttle Type to FIXED,
disable the Current Limiting, and set the Cutoff Voltage to
a fixed minimum that disables low-voltage cut-off. My philosophy
is that I know what I am doing and I want to be in control.
Experience has taught me that this type of plane will no longer
fly before I deplete the LiPo packs to an unsafe level. The
drop in power is very noticeable and it allows me to properly
land without undue stress from having the motor stop while in
that this setting scenario will not always apply to all
types of models or to other modelers.
the intermediate level electric flight enthusiast, I recommend
the "Auto Li-po" Cutoff Voltage and the "Normal"
Current Limiting settings for added safety to the ESC and battery
The assembly starts by attaching the ailerons and flaps. To attach
the ailerons, it is helpful to first drill 1/16" holes in
the slots to aid the CA in wicking farther into the surfaces.
I also used Dubro (#252) T-pins to keep the hinge centered when
pressing it into place. The ailerons hinges were then glued with
ZAP Thin CA.
flaps were attached by gluing the supplied nylon hinges with epoxy.
I first tested the fit and found one hole that wasn't drilled
all the way. After drilling the opening longer, the hinges were
glued with 5-minute epoxy. Note that the manual calls for using
30-minute to allow sufficient time, if needed.
I didn't see it in the manual, I found two plastic machine gun
pieces in the box. With some silver paint and 1/8" brass
tubing, you can easily add a scale-looking hop-up to the P-51D
without an airbrush.
aileron and flap servos installed quickly. After first mounting
the hatch blocks with Pacer 5-minute Z-poxy, the DS821 servos
were screwed into place. I followed the manual's recommendation
for servo extensions and routing the wires to the exit hole that
will go inside the fuselage.
aileron linkage uses a 2" threaded rod and the flap linkage
uses a 1-1/2" threaded rod. A metal clevis and nut was included
in the kit for each end of the rod but I added my own keepers
from cut fuel line hose. I was pleased to see that control horn
mounting for both the flap and the aileron is not visible from
the top side of the wing. It is obvious that special attention
has been designed into the Hangar 9 P-51D to keep it looking scale.
retract installation went well but it did take some thought
to properly set up the linkage as the photos in the manual were
limited. All the hardware is supplied except for the needed
1/2" machined servo arm (HAN3531). I also added some small
plastic spacers between the gear door and the retract. The wheel
comes pre-installed onto the strut. The strut assembly is simply
pressed into the retract mechanism and then tightened in place.
second retract installation was easier after learning from the
previous one. By adjusting the length of the small plastic spacers,
the gear door can be made to sit perfectly in-line with the
that one retract servo is reversed or you must use a reversing
second retract installed much easier after learning from the
first one. I adjusted one of the plastic spacers between the
retract mount and the cover for a perfect alignment with the
two wing halves were prepared for joining and then epoxied together.
The fit was excellent! Note that three servo control lines exit
from each wing half. I labeled each control line near the connector
with a sticky-back cable label.
mounting the wing, I choose not to use the supplied nylon 1/4-20
screws and tubes. Instead, I used metal Hillman furniture bolts
and held them in place with some spare APC prop spacers. The
Hillman bolts use a 5/32 hex wrench to tighten. On planes this
size, I find myself wanting more wing security and easier installation.
The metal Hillman furniture bolts won't stretch or degrade with
use. The hex wrench won't slip off like the slotted screwdriver
needed for the nylon screws. The fiberglass air scoop needed
some slight sanding before being epoxied in place.
decided to make a change to my receiver battery. For my P-51D
conversion, I will replaced the 4.8v 1100mAh NiCD receiver battery
with two Ultimate BECs from Hobby Lobby. The so-called UBEC
eliminates the need to keep a separate receiver battery charged
as it takes power right from the main flight packs.
that you can simply use a single UBEC if you like. Be sure to
use the 5v version as the JRPS791 retract servos do not like
running on 6v.
need to keep multiple Rx. battery packs charged.
using dual UBECs, one UBEC will provide 6v to the receiver and
servos while the second UBEC will provide 5v for the three retract
servos. In this manner, the control surfaces will have the benefit
of higher torque and speed from the 6v, 20 gram, UBEC and the
added safety from the isolation of a retract jam.
using a JR Matchbox for my 2 retract servos, I can simply plug
the retract servos into the 4-channel Matchbox, plug in the 5v
UBEC output into the Aux. Batt. jack, and plug in the supplied
extension cable (shown left) to channel 5 of my DX7 receiver.
Note that the jumper plug with the red wire in the Aux. Batt.
jack is removed when feeding external power to the servos instead
of using power from the receiver.
JR Matchbox is a convenient way to manage power routing and control
surfaces using multiple servos.
wiring harness for my P-51D is greatly simplified by the new
6970 Arming Switch from MPI. It can be mounted right in the
fuselage and will either arm or disable my entire power system
with a single plug.
rudder and horizontal stabilizer mounting were very easy. The
fuselage comes with the vertical stabilizer already mounted
so the rudder is simply held in place with CA hinges. The horizontal
stab is aligned by two support bars and held with 4-40 screws
that need to be tapped after drilling holes.
assembly design makes the elevator removable for traveling or
cut an extra access opening to test the fit of a Robart 121
retract mechanism but discovered that it would not fit due to
the existing control rods. The rework would not have been a
minor task so I decided to use the stock tailwheel system.
stock tailwheel system installed easy but there was some binding
on both the tailwheel and the mount on the gear wire that needed
to be sanded. I wrapped a small piece of fine sandpaper around
a toothpick to lightly sand the insides of the wheel and pre-installed
mount holes. I made a few minor modifications to the stock assembly.
First, I added a second wheel collar to the inside of the wire
to make the tailwheel sit centered under the fuselage. Second,
I replaced the stock 8mm screw that tightens the turning arm
on the wire with a socket head screw which is much easier to
tighten with a hex wrench in the confined area.
pilot for the Hangar 9 P-51D is from Century
Jet Models. The lower torso was easily removed with
a craft saw as it was originally pieced together at the
waist area. I added my own touch-ups to the pre-painted
pilot figure and cut the stock plastic cockpit seat from
the P-51D detail kit. By adding half of a shoulder strap
to the back of the seat, it enhanced the scale look. The
control stick was made from a rubber grommet base, grey
control tube section, and a hand-cut rubber handle.
dash gauge decal was transfered to a piece of cardboard
before gluing into the cockpit. I also decided to screw
the canopy in place instead of gluing it so I can add further
scale details in the future. The canopy screws were colored
black with a fine tip marker. Adding simple details like
this is a great deal of fun and adds to the scale realism
of the warbird.
E-flite Power 160 motor uses a similar x-mount to the AXI
5330 motor. This meant that the nylon spacers and screws from
Hobby Lobby could be used to mount the motor in the P-51D.
Since the 4" long 8-32 screws were not long enough, I
needed to extend the firewall by making a box from 5-ply aircraft
grade plywood and hardwood blocks.
mounting the extension to the firewall, I drilled several
air holes and mounted #10-24 T-nuts. The extension was coated
with epoxy and then screwed into place. I also used some Pacer
Z-42 Thread Locker on the 2" long #10 screws. Not shown
in the first two photos are two smaller blocks that were glued
and screwed into place on each side of the narrow middle section.
They can be seen in the motor photos.
used 3-1/8" of spacers (two 1" spacers, two 1/2"
spacers, one 1/8" spacer) between the x-mount and the
firewall extension box. An additional 1/4" spacer was
used to take up some screw length so it didn't run into the
original firewall. This provided about a 3/16" gap between
the spinner backplate and the cowl. The 4" long screws
were easily secured by a screwdriver entering the front of
the cowl. Again, Pacer Z-42 Thread Locker was used to keep
the screws secure.
Castle Creations Phoenix HV 110 ESC is an overkill for this
application but it makes me feel safer that I will not be
pushing the speed control to its limits. The HV 110 ESC can
use up to 36 cells NiCd/NiMH or a 12s LiPo pack. The 110 amp
current rating can deliver up to 5500 watts (or 7h.p.) of
power. I plan to have about 3000 watts of full throttle power
in my final setup.
mounting the ESC, it was prepared with a Dean's Ultra male
connector and the mating connectors from the E-flite Power
160 motor. It mounted easily between the nylon spacers using
a single tywrap. A few extra tywraps were used to hold the
wires away from the rotating can. A few extra tywraps were
used to hold the wires away from the rotating can. Although
it is possible to swap two of the wires to reverse the motor
rotation, it was not needed since the Castle LINK software
allowed me to reverse the motor direction without changing
mounting the cowl bottom, the spinner backplate was perfectly
oriented and extended 3/16" from the cowl. Note that
the Graupner 16x8 3-blade prop shown is for testing the power
system so I could decide on my final prop size and blade count.
At this time, I expect that an 18" 3 to 4 blade or 19"
to 20" 2-blade prop is needed on a 10s-12s LiPo pack.
Another undocumented scale item in my P-51D box was the exhaust
manifold. I now believe that these parts, along with the machine
gun barrels, are part of the Scale Detail Set. Although the
manual has this set as part number HAN4065, the same part number
shows up as the scale spinner on the Horizon Hobby Web site.
painted the pipes black and added some sticky-back rubber pads
to change the shape a bit. The manifolds were attached to the
fuselage with three black screws that I supplied. Alternately,
you can also glue the manifolds to the fuselage using RC-56
MPI Arming Switch mounted easily in the soft thick balsa area
of the fuselage side. I used the supplied screws, washers, and
nuts to keep it secure. I re-wired my MPI Arming Switch to eliminate
a pair of Dean's Ultra connectors. Since I am using two packs
in series to obtain either a 10s or 12s total voltage, I also
needed an On/Off switch in-line with the UBEC power inputs.
finish the inside hook-up, I used three JR DS821 digital servos
to control the rudder, tailwheel, and two elevator halves.
Spektrum AR7000 dual receiver was positioned per the manual recommendations.
Remember to re-bind the receiver after all the control surfaces
have been set up for their fail-safe positions. When the model
has retracts like my P-51, I find it preferable to have the GEAR
DOWN position set so that no movement occurs on the flight line
when I arm the plane.
5v UBEC feeds power to the retracts via the JR Matchbox. The two
retract servo cables then plug into the JR Matchbox. The 6v UBEV
for receiver/servo power is under the servo bay.
Universal Battery Eliminator Circuit (aka Ultimate BEC, UBEC)
is made by Kool Flight Systems and is available through Hobby
Lobby. It is an external circuit that taps power from your battery
flight pack and regulates the voltage to the necessary 5 volts
to power your receiver and servos. It does not replace the speed
control. However, it replaces the BEC function in a speed control
with much more capabilities.
can handle up to a 29 cell battery pack (35 volts input)
can power up to 8-10 servos (3-5 amps)
versions exist for higher input voltages and for 6v outputs
JR Matchbox serves several purposes in my setup. It acts as a
device for easy power separation for my dual UBEC scheme as I
can simply plug the other UBEC power into the isolated power input
of the matchbox. In this manner, a retract jam will not take out
my receiver and plane control servos. Fortunately, the design
of the integrated retract mechanisms in the P-51D will be difficult
to jam so a single 5v UBEC could be used for the entire system.
Other retract systems that use long linkages with elbows in the
middle are more prone to jamming.
JR Matchbox also allows me to use the same retract servo for the
opposite wing side as it can provide reserving. The alternative
is to buy the mating reverse retract servo or use a reversing
Y-harness. Finally, when I was considering a third retract servo
for my tailwheel, the Matchbox would allow for an easy plug-in
of this third servo. Overall, the JR Matchbox is a convenient
way to manage power routing and control surfaces using multiple
shown in the photo are the two "Y" harness cables needed
for the ailerons and flaps. The flaps use a reversing "Y"
6s and 4s 5000mAh 20C PolyQuest LiPo packs are held in place by
Velcro and some foam blocks (not shown). I created a platform
for the packs using plywood slats and then glued mating Velcro
to the surface. Note that the arrows denote that the packs were
moved forward to just behind the firewall for a perfect balance.
Only half of the pack should remain visible in this view.
decided to create a custom P-51 fuselage holder so that I could
use it in my new trailer for traveling as well as on the field
benches for mounting the wing. The plane is now easily assembled
and the power system completely disarmed until I insert the MPI
Arming Plug and turn on the On/Off switch to the radio. There
is no movement on any control surface including the retracts.
Zinger 18x10 4-blade prop arrived today. Joe Zingali even made
the hub hole 12mm (by request) for a perfect fit. The $57 pre-assembled
prop costs $67 including shipping. The Zinger 2, 3, and 4 blade
props can be purchased in many sizes. Remember to specify the
"pro" blades as shown painted below. The older standard
blades shown above are not efficient by today's standards.
Zinger 4-blade prop was painted black with yellow tips by my friend,
Paul Weigand. He also added the Hamilton Standard decals made
by Major Decals for an added scale touch. These decals are available
from Horizon Hobby (p/n MAJP6WT)
or your local hobby shop.
that we added a pin in the prop hub to key the spinner backplate.
The black markings in the front help orient all the pieces including
the spinner as it is cut to fit the blades and the mounting screw
holes. The finished prop and stock spinner looked great!
Hangar 9 150-size P-51D is finished and passed the ground testing.
We set the control surfaces per the manual but added additional
elevator throw and exponential to help combat a possible nose
over when landing on grass. In the past, warbird designs like
the P-51 would not have the gear mains mounted forward enough
to help prevent noseovers. As it turned out, we discovered that
the Hangar 9 150-size P-51D had no tendancy to nose over on grass
goal for this project was to have a full throttle current between
80-90 amps. This parameter stresses the motor most as it is rated
for 80 amps for 15 seconds. Assuming a 10%-15% offloading in the
air, and proper air cooling, the P-51 can then burst about 3000
watts for some impressive fly-bys. A 20C 5000mAh pack can deliver
100 amps. LiPo savvy users know that this should really be the
burst current setup and that 70% of this marketed rating can actually
be used for continuous current delivery. This rule of thumb in
today's marketing helps to ensure that 100-300 pack cycles can
power system measured 3300 watts at 100amps using a 10s (20C)
Lipo supply. With a 10% minimum unloading in the air, this puts
me right on my target goal of 90 amps with a power level around
200w/lb at an all up weight of 16lbs. I was excited to my warbird
in the air!
We waited to test fly the Hangar 9 P-51D until a beautiful spring
weekend arrived in upstate NY. The P-51D performed very well
with the electric power system and easily landed without flaps.
Take-offs, landings, and aerobatics were smooth and predictable.
The forward positioned gear mains had no tenancy to create a
nose over on grass. The torque of the 4-blade prop was impressive,
requiring rudder and aileron compensation. The retracts worked
great and the built-in struts provided for smoother take-offs
only poor performance came from the low quality linkages on
the ailerons and flaps. Several of the threaded control rods
pulled out from the metal clevises as if the rod diameter was
not a good fit. This prevented us from testing the flaps properly.
The longer elevator and rudder control rods did not exhibit
this loose coupling problem with the metal clevis. I plan to
replace the threaded rods and metals clevises with some Dubro
4-40 rods and linkage hardware. Only one side of the aileron
and flap linkage needs to be adjustable so the other side can
have the clevis soldered in place.
video of my Hangar 9 150-size P-51D shows the first two flights
in 10-15mph wind. Both landings were without flaps on the grass
runway. The elevator was a bit too sensitive on the first flight.
After the first flight, the battery packs were moved forward
to just behind the firewall for a perfect balance. The performance
of the E-flite Power 160 motor is a perfect match for this great
looking scale warbird. On the second flight, I attached my eDVR
and added a few quick clips for a Pilot CAM view from the air.
A few of the last fly-bys include real P-51 engine sound. It
is difficult to tell if this is an R/C model or full scale plane!
The Hangar 9 150-size P-51D Mustang ARF is a winner! The assembly
time is quick and provides a great large-scale experience for
scale flying enthusiasts with intermediate to advanced flying
skills. The level of exceptional scale detail will catch the modeler's
eyes at the flying field and the performance of the E-flite Power
160 motor will leave them very impressed. The model will stay
clean using the electric power system and can be flown at all
R/C events. The electric power system also allows for using a
4-blade prop for that added a great scale touch on the ground
and in the air.
UltraTract metal retracts, struts, scale flaps, authentic UltraCote
trim scheme, and prepainted aluminum spinner, all demonstrate
that Hangar 9 has gone the extra mile to produce a World War II
fighter that looks, and flies, as if it really could be raiding
Japanese forces in the Pacific theater. My only concern was with
the aileron and flap linkage rods as they did not securely screw
into the metal clevises. Other than that, this plane will proudly
sit next to my Hangar 9 .60-size Corsair on the flying field...ready
