    RCUniverse.com Review of the Flyzone Select Scale F4U Corsair Tx-R

    • Available in RTF and Tx-R versions
    • 3S or 4S power
    • Quick Assembly
    • Rotating retracts with functional gear doors
    • Navigation lights
    • Included pilot figure
    • Molded panel lines

    • Replica radial is missing a cylinder.

    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.

    Overview

    Flyzone makes it easy to fly the famous bent-wing fighter ? AND includes exciting features, such as navigation lights and retracts, that most other Corsair models require as extras. Choose the RTF for all-in-one convenience, or use your favorite transmitter with AnyLink to pilot the Tx-R. At a park or local club site, all eyes will be on you flying the Select Scale Corsair!

    Specs

    Wingspan: 48.5 in 
    RTF Weight: 48 oz 
    Length: 38.5 in 
    Wing Area:426 in2
    Wing Loading:16 oz/ft2
    Requires:Anylink compatible 5-channel transmitter





    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.
