ParkZone
has introduced a redesigned P-51 Mustang Park Flyer. This
new design is made from the tough "Z-Foam?",
has dual aileron servos for better control and a large magnetic
hatch to access the radio gear. You can purchase this plane
in two versions, a Ready to Fly (RTF) with a 27 mHz radio
or a Bind and Fly (BNF) version for a 2.4 GHz Spectrum Radio.
This
review will look at both the RTF and BNF versions of the airplane.

First
Look
The
ParkZone P-51D BL comes well packaged in a full color cardboard
and foam box. The Ready to Fly (RTF) version shown below comes with
a 27 MHz transmitter.
The
Bind and Fly (BNF) version shown below is identical to the RTF,
but it is packaged without a transmitter. The BNF version also includes
a pushrod and hardware for the optional rudder (servo not included).
The
airplane includes a 1300 mAh 3S LiPo battery and charger. The charger
is designed to be plugged into a 12V socket in a vehicle. The RTF
version transmitter is packaged with 8 AA batteries. Also included
is the screw that hold the wing to the fuselage, the tape that secure
the horizontal tail to the fuselage and a piece of tubing.
Shown
below are the optional rudder parts, a bind plug for the spectrum
radio and the screw, tape and tubing shown previously. The manual
is well illustrated and easy to read.

Assembly
Assembly
of the ParkZone P-51D BL Mustang is very quick. Slide the wing into
place, and secure it with the Phillips screw. Next, hook up the aileron
leads to the Y-harness. You can plug either lead into either plug.
Next
install the tail on the airplane. The elevator even comes with the
control horn pre-installed. Just slide the tail into the slot on
the fuselage, and secure it with 4 pieces of the supplied tape.
Then connect the elevator pushrod to the control horn.
The
ailerons come pre-hinged and the servos are installed and connected
to the control surfaces. The motor, propeller and spinner even come
installed. This airplane has some great details including molded
in panel lines and wing guns.
Tucked
under the canopy is a pilot decked out in WWII gear. The yellow
and red tail is very eye catching, especially in flight. The cowling
includes molded exhaust stacks. The only thing that is missing is
the awesome rumble of a V-12 engine.

Technical
Data
The
ready to fly weight of the airplane (RTF) was 1lbs 7oz. With a fully
charged battery, the ParkZone P-51D BL produced 2 lbs of thrust
at 8055 RPM, 17.3 amps, 197 watts with 11.43 volts under load (12.60
volts no load). That gives the airplane a 1.39:1 thrust to weight
ratio.
At
partial throttle where the airplane is comfortable cruising around,
the airplane was running at 49 watts, 11.52 volts under load and
4.2 amps, turning the propeller at 5000 RPM. At this throttle settings,
I was able to fly the airplane for 12-15 minutes at a time.

Flight
Takeoff
is easy. Apply full throttle and give it a good sturdy toss into
the wind. I prefer to hold the model in my left hand so I can have
my right hand on the ailerons and elevator in case something goes
wrong. If it's very windy, I would recommend that you have someone
hand launch it for you.
The
ParkZone P-51D BL flies great. It's not pitch sensitive and it flies
just as well fast as it does slow. After the first launch, I trimmed
the planes out and left it there. Both models only required minor
trimming.
Aerobatics
are nice and predictable. Loops are generally nice and round from
full throttle level flight. I found it helpful to dive slightly
to make sure loops are round when flying at less than full throttle.
Inverted flight requires a touch of up-elevtaor and rolls require
just a touch while inverted to remain axial. The other two pilots
and myself wished we had the extra control of the rudder while doing
aerobatics. Having the rudder will also allow you to slip the airplane
into tighter landing spots.
The
P-51D BL will handle a fair amount of wind. Just be sure to launch
into the wind. If your launching in moderate or gusty wind, get
someone to hand launch it for you so you can be ready on the controls.
Landing
is easy. The model slows down well and will not float as long as
you don't come in too fast. The big scoop on the belly will slow
this model down quick in the grass. Because this model is hand launched
and belly landed, it's well suited for the smaller flying field
like the local park or school field.
Flight Report
Takeoff:
Since
there is no landing gear, takeoff is a simple hand launch. The
plane has enough power, and a sturdy toss into the wind will
get you airborne.
Slow
Flight, Stalls and Spins:
Slow
flight is predictable, and the stall is tame. Since the optional
rudder was not installed for the review, I did not try spins.
Basic
Aerobatics (Aileron / Elevator):
Loops
and rolls are a lot of fun. With the controls set on high rates
you will need to add some up elevator during the second half
of the roll to keep the nose from tucking under. Add a little
less elevator for a barrel roll. Inverted flight requires some
up elevator to maintain level flight.
Advanced
Aerobatics (Aileron / Elevator / Rudder):
Neither
planes evaluated in this review had the optional rudder servo
installed (the hardware comes with the BNF version, but not
the RTF). If you purchase the BNF version, I would recommend
installing the extra servo.
Trim:
Once
I trimmed the model in roll and pitch, I did not change it for
the rest of the flight. This model doesn't require any additional
trim when coming into land.
Go-Arounds:
Go-arounds
are predictable and easy.
Landing:
Landings
are simple. Line up with the runway and cut the power before
touchdown. Hold some up elevator until the model runs out
of speed an inch or two above the ground.

The
ParkZone P-51D BL Mustang is well suited for the park flying field.
It hand launches easy and lands anywhere you can slide it to a stop.
The airplane doesn't have any bad habits that I could find. While
it's not a trainer, it would be a great second airplane. The kit
comes well packaged and ready to fly. It takes longer to charge
the battery than to assemble this airplane.
I
was very impressed with the "Z-Foam?" construction.
The fuselage has lots of molded in panel lines and the paint looks
great. The thing that impressed me the most is that you can glue
this foam with regular CA glue (you don't need special foam safe
CA). One of the review planes needed some repair and I used a technique
that I read on the fourms. Simply spray CA Accelerator (also called
"kicker") on to one side of the repair. Put your medium
or thin CA on the other side and press them together. I found this
technique worked great. Without the accelerator/kicker the CA takes
a long time to dry. I was able to glue a fuselage that was in 2
different halves back together in very little time. I also like
that ParkZone has made all the individual parts available for purchase.
That means if you bang up your P-51, then you'll be able to repair
it at minimal cost.
I
really liked the large hatch to access all the radio gear. This
feature is one of the great things that ParkZone incorporated into
this design from the T-28 and Corsair airplanes. It's held in with
a rare-earth magnet and is very easy to remove and replace.
The
only thing that I didn't like about this plane, is that the batteries
and speed controller come with a proprietary "ParkZone"
plug. That means that it's not compatible with my other LiPo battery's.
I have several of the 3S LiPo 1300 mAh batteries that this plane
uses, but could only use the battery that came with the plane. All
my LiPo battery's use the very common Deans or UltraDeans connectors
that is industry standard.
To
sum it up, I had a blast flying these airplanes. It's likely I'll
have one in the truck almost all the time so I can go get that quick
flight in at the end of the day. It's the perfect airplane to release
the stresses from the day. This pair of Mustangs got a lot of complements
on the flightline and in the air. While faster than my ParkZone
T-28, its still easy to fly. And you have to love those high speed
passes. Now if we can get ParkZone to make this thing rumble like
the full-scale P-51's.....

As there are several different battery plugs out there on the market, simply make a "jumper" to connect with your choice of connector. Would be a shame to take this awesome little Mustang to the park or flying field................and only fly it once!
