Flyzone
has recently released a new Select Scale rendition of the famous bent
wing fighter, the F4U Corsair. Finished with the famous Major
Gregory 'Pappy' Boyington number 86 'Lulubelle' trim scheme and
being a Select Scale model, the F4U
Corsair ships with an impressive list of features that is sure to
thrill warbird and scale enthusiast such as navigation lights, a pilot
figure, molded panel lines, a replica radial engine and rotating
retracts complete with functioning gear doors.
The
F4U Corsair is constructed from AeroCell foam which is know to be light
and durable. The F4U Corsair is
available as an RTF which includes the TTX600 radio or as an Tx-R
version which allows the modeler to use virtually any transmitter with
the AnyLink adapter.
Power
is supplied via a brushless motor and
ESC and can be powered by either a 3S2100mAh battery or for more speed
and climb a 4S2100mAh battery without having to change out the ESC,
motor or propeller which is a very nice and rare feature in a model of
this size and price range. The
F4U Corsair arrives with all of the electronics pre-installed which
includes five micro servos for the control surfaces and the retracts.
This review will be based on the Tx-R version of the Select Scale F4U Corsair which does not arrive with the TTX600 transmitter.
As you open the box, you will notice that the components have been individually wrapped and secured in the box.
Due to the low component count, the time to get the F4U Corsair ready for its first flight should be minimal.

One
of the biggest things that the F4U Corsair has going for it is the
inclusion of the rotating retracts with the functional gear doors. When
you flip the wing over and look at the bottom, you will find the gear
doors that are completely flush with the bottom of the wing which not only look great but will help in reducing drag. Powering
the system and actuating the retracts, you will see the mechanism springs to life as
the retracts rotate and flip open albeit a bit too fast for scale like
operation. The included struts have a shock absorbing feature and are
painted white and I have to say look great. The gear doors are actuated
by a metal lever that is connected to the strut which is a simple and
hopefully fool proof way to achieve this great feature. The steerable
tail wheel is not retractable but arrives with a shock absorbing setup.
The
wings are detailed with panel lines and the linkages for the ailerons
are concealed inside the wings. A single servo actuates both ailerons.
The guns and radiators are visible from the front which add the scale
touches that should make this Corsair standout from the crowd of foam
Corsairs out there. Navigation lights have been attached and are functional on the wingtips seated in clear plastic.
About
the only thing that stands a bit off on the F4U Corsair is the radial
engine which seems to be missing a cylinder head but looks good
regardless. A painted pilot figure of Major Boyington has been included with the F4U
Corsair and adding a small scale antenna should not be that hard for
the inclined modeler.
The
cowl is
pre-attached to the fuselage and has small vents on the sides to allow
for hot air to exit and help cool the brushless power system. The
horizontal and vertical stabilizers have also been treated to the
detailed panel lines. The Tx-R version does not ship with a battery or
charger.
Tactic
AnyLink Adapter
A
transmitter alone can only do so much. But a transmitter with AnyLink?
can do wonders. It's so revolutionary that a patent is already pending,
and so simple to use that it takes only seconds to add. Yet, once it?s
installed, your transmitter will be able to fly:
All
Tx-R? (Transmitter-Ready?) airplanes;
Most
electric aircraft equipped with a 2.4GHz SLT? receiver.
But
that?s not the only amazing thing about AnyLink. Here are three more:
AnyLink
works with virtually any transmitter, regardless of brand, band or
modulation.
AnyLink
enables your transmitter to send out a true, 2.4GHz signal ? and
operate with all of the interference-free dependability of a
frequency-hopping, spread-spectrum system.
AnyLink
offers all of the convenience, versatility and benefits listed above
for far less than the cost of a new 2.4GHz radio system.
The
battery compartment is accessed via a small hatch on the top of the
fuselage that is held in place with a small plastic latching mechanism which secures the hatch nicely to make sure it does not blow off during those high speed passes down the runway.
The Tx-R version will require an AnyLink adapter or a TTX transmitter with at least 5 channels.
The
assembly process of the F4U Corsair starts by attaching the vertical
stabilizer to the fuselage. The concealed control linkage is connected
to the pre-routed control rod and the vertical stabilizer slides in
place and is held in place with a single screw. I usually hang my
planes to a peg board by their tails and found that after a while the
whole mechanism had worked loose so you may want to glue the assembly
in place and cover the screw opening with some white balsa filler.
The
vertical stabilizer slides in to the top of the fuselage and is held in
place with a screw that is affixed from the bottom of the fuselage. The
elevator and rudder control linkages can then be adjusted from under
the fuselage using the easy set screws on the control arms.
The wing can then be mounted to the airframe. All of the servo leads are marked which makes the process straight forward.
The wing is held in place with a single screw. Once the wing has been
mounted and the system bound and powered on, the retracts can be
actuated.
The
flight battery installation requires a bit of maneuvering to get the
battery installed in the forward position of the fuselage.
The battery is held in place securely with Velcro strips that are
attached to the bottom of the battery and I did not see a need for any
additional tie down strips. Both the 3S and 4S battery (which is a bit
taller) can fit easily in the forward location inside the fuselage
which was a nice treat. The propeller and spinner can then be
attached to the motor and the F4U Corsair is virtually ready for its
maiden flight.
The
overall weight of the Corsair (minus flight battery) was 43.6 oz. The
3S flight battery came in at 6.5oz and was able to produce 400W at 35A
while the 4S battery was 8.7oz and could produce 690W at 50A. With only
~2oz between the flight packs, I did not see a major difference in the
balance of the airplane both on the table and in the air which means I
could swap out the batteries at will without having to worry about
re-balancing the airframe.
Finding
good weather to maiden a new airplane in Houston is sometimes a
challenge. Even though the weather is not very cold in the winter,
the wind is usually another story. That is why when we found a
semi calm and sunny day in December after waiting for a few rainy and
windy weekends, we were out at the field ready for a full day of flying.
Having
a 48.5 in wingspan, the F4U Corsair can be transported to the field
without having to take the wings off so field assembly in my case was
non existent. Once at the field, I double checked the recommended C.G.
and control throws per the manual and installed the 3S flight battery in
anticipation of the first flight.
On
the ground, the steerable tail wheel does a good job and as long as the
tail is down, taxiing the Corsair does not provide any challenge. With
the runway cleared and the Corsair facing the wind for its first
flight, I advanced the throttle and watched as the tail quickly lifted
off and the F4U Corsair was climbing in no time at all. Right rudder
has to be applied as with any other tail dragger and the rudder is
quite effective in keeping the nose pointed straight during take off.
Once
in the air, I pulled in the gear trimmed out the F4U Corsair and took
it high to experiment with its stall characteristics. As I slowed the
Corsair down, I waited for a premature stall to occur which thankfully
never happened. I was amazed at how slow I could fly the Corsair with
complete control and without fear of a stall. The Corsair seems to be
impossible to stall when reducing power from level flight as it simply
wants to glide without dropping the nose or wingtip. To induce a stall,
I raised the noise and backed off the throttle and with the noise
pointed up I did finally get
the Corsair to stall. Recovery was as simple as applying throttle as
the nose pointed down and flying out without loosing a great amount of
altitude.
After
experimenting with the stall characteristics, I advanced the throttle
and found that the F4U Corsair can respond with nice high speed passes
over the runway which we clocked at 55-60mph with a radar gun. With the
4S battery installed, the Corsair really comes to life with very good
vertical performance and level passes in the 70-75mph range but at the
cost of reduced flight times of course. Loops from level flight and
slow and scale like barrel
rolls are all possible with the provided power system and control
surfaces. I found the recommended elevator throws to be a bit too
sensitive which I quickly remedied by adding a bit of exponential to
the elevator. The recommended roll rates allow for some scale like
rolls. The Corsair can maintain inverted flight and can perform pretty
much any sport maneuver such as split-S, Immelman and stall turns.
Since
the Corsair has functional gear doors, I was initially worried that the
additional drag induced by the gear doors with the gear down would
cause unwanted flight characteristics but found this to not be a major issue
as I dropped the gear and performed a few circuits before approaching
for landing. With the Corsair lined up over the runway, I reduced the
throttle and watched as the Corsair bled off its speed and altitude and
approached the runway in a controlled manner. The ailerons provide good
control even at lower speeds to handle the runaway gusts that seems to
want to flip you over right before touchdown.The Corsair exhibits an excellent glide ratio that is easily controllable all the
way down to touching down on the runway which made landing the Corsair
a breeze.
Flyzone Select Scale F4U Corsair
I
am a sucker for Corsairs and the new Flyzone Select Scale F4U
Corsair has all of the right components to make it a winner in my book.
Inclusion of scale details such a pilot figure, panel lines, a replica
radial engine, guns and rotating retracts with functional bay doors is
a great plus in a model of this size and price range. The fact that the
provided power system can handle 3S and 4S batteries for increased
speed and vertical performance is a huge benefit that you will not
easily find in competing models. The rotating
retracts have worked flawlessly so far and I do not have any reason to
expect anything but good performance from them going forward. The
functional gear doors are simply amazing and add the final touch of
scale realism which will make you want to choose this airframe
every time you head out to the field. I do wish that the speed of the
retracts could be slowed down a touch as neither the TTX600 or the
Futaba 8FGS radio that I had provided the servo speed capability which
would allow me to achieve this. Great job Flyzone.
