    RCUniverse.com Review of the Wings Maker DF032

    • Futuristic look
    • Impressive flat spin!
    • Speed - very fast!
    • Easy to launch
    • Easy to land

    • Nose cone adhesive needs to be reinforced

    Flyzone pays tribute to the recent discovery that confirmed the existence of Higgs Boson conducted at the Large Hadron Collider (LHC) near Geneva, Switzerland. This collider is a 27 kilometer ring (yes, 16.8 miles!) used to accelerate particles to get them to collide at the highest energy. The collision data enables scientists to study, in detail, the subatomic structure of the matter and the laws of nature. The Hadron itself is a composite particle held together by one of the four fundamental forces of the universe: the strong force, which explains the title!

    High energy is required to enter the inner world of the atom, and to achieve this requires extremely high velocity, which is what Flyzone's Hadron is all about! This flying wing comes with a free side adrenaline, standard with every outing. To reproduce the effect of particles colliding, Flyzone decided to equip the wing with a thrust vectoring pusher engine, which allows for crisp and sudden direction changes and impressive maneuvers and spins.

    The Hadron is available in two versions:

    • (Tx-R )- Transmitter ready version that will work with any SLT ready radio
    • (Rx-R) - Receiver ready system. You will need your own radio system, including a receiver.

      We are reviewing the Tx-R version. The radio used for the test is a Futaba 14SG, equipped with a Tactic Module.

    The model comes in a fairly large box, with pictures of the Hadron close to its actual size.

    Several blocks of expanded polystyrene are glued inside the box to keep the model and parts in place.

    The Hadron is almost entirely build as it comes out of the box. Only a few assembly steps are left for the user.

    Included in the box:

    • Plane and the rudder
    • Two noses
    • Battery and charger
    • Propeller for 3S battery
    • Propeller for 4S battery
    • Battery and canopy latching system parts
    • Manual

    Manufacturer Information
    Rx-R version: $220
    Tx-R version : $280

    With nearly all of their flying surfaces horizontal by design, flying wings are limited when it comes to yaw authority. The Flyzone Hadron stretches the envelope to include violent spinning maneuvers and extreme aerobatics. How? Credit the large fin, plus a thrust vectoring unit that allows the Hadron's experienced pilot to tilt the motor and redirect the thrust. This gives the model greater maneuvering potential in addition to exciting speed!


    Wingspan: 33.5 in (850mm) 
    Length: 33.5 in (850mm) 
    Weight: 29.6 oz (840g)
    Battery: 2200mAh 3S 30C LiPo or
    2200mAh 4S 30C LiPo

    The nose cone attaches to the fuselage by a magnet which is glued onto the foam. While a unique design for the nose, the adhesive holding the magnet is not as strong as it needs to be. Mine detached before my first flight, so I opted to secure it by taping it in place. The magnet used to hold the canopy is much stronger and bonded more efficiently. The canopy mechanism is made with an added plastic piece as a medium between the foam and the magnet.

    The fuselage is reinforced with a carbon tube, which doubles as a battery holder. The battery is strapped to the tube using a Velcro band. The servos are pre-installed, as well as the control horns and linkages. Be sure to double check the assembly and the bonding of the horns with the ailerons. On the model I received, one aileron horn was loose and had to be glued back.  The rudder is secured with 2 screws.

    The vectoring unit is installed and ready to go. It is driven by a servo that is directly connected to the receiver. It can be coupled to the rudder control by mixing the channels on the radio. That is the best option, as that link can be enabled/disabled by flipping a switch in flight. Another option is to use a Y cable.

    The inner walls of the fuselage are marked, to help with the battery placement. Due to the very large fuselage, numerous battery types can be used and secured accordingly to keep the CG at the appropriate location.

    The Hadron is a power-hungry guy that quickly transforms electrons into speed. I tested the plane with 3 different batteries: the

    • 3S 30c 2200mAh (provided)
    • 3S 45c 2200mAh
    • 4S 45c 2200mAh battery
    For the 4S 45c 2200mAh battery, the propeller was switched to the lower diameter version provided with the kit. As you can see from the above logs, the power can rise to some impressive values, and the Hadron flies like some ballistic particles as the power increases.

    It is interesting to see that, while the high end 45C battery provides a better voltage stability and a slightly higher current that the stock battery, the difference in flight is only marginal.

    However, there is a big difference flying the Hadron on the 4S battery.

    Hand launch:

    There is a very handy finger-grip feature underneath the plane. This makes the Hadron very easy to throw. The plane did not have any tendency to roll on launch due to the motor torque. A simple toss at a 20 to 30 degrees climb angle and 2/3 of the throttle is all it needs, and the Hadron handles the rest from there.

    Flight on 3S battery:

    The plane only required a couple clicks to fly straight, and the fun began as soon as it was trimmed. The plane is very responsive on all axis, and the power is far from missing. Unlimited climbs are part of the flying envelop on the included 3S battery.

    With the vectoring thrust disabled, the Hadron is a reactive little flier that perform all acrobatic maneuvers in the book. The knife edge requires some speed, and a very large compensation in the opposite direction on the ailerons. This has a tendency of making the plane unstable and overdoing it will make it snap. The roll rate is very fast, and one has to concentrate to stop on the right position.

    Performing a nice and round loop is easy. Inverted fly requires a larger amount of down elevator than a standard pattern plane, but this is expected for a flying wing. The Hadron can perform the fun elevator maneuvers. Make sure you slow down the Hadron, while pulling the elevator to keep the fuselage horizontal. The nose should only be slightly up. Once the motor is completely stopped, you should have full elevator. The Hadron goes down on an almost vertical trajectory, perfectly leveled and flat, with a slight wing rocking. Re-apply the throttle slowly as you let go of the elevator to retrieve a normal flight mode. Be sure to synchronize these two actions: if the throttle is reapplied too quickly with too much elevator, the Hadron might actually stall!

    Now, with the vectoring thrust enabled, the Hadron becomes an entirely new beast! The first maneuver I tried was the flat spin, as shown on Flyzone's video. The Hadron is brought full throttle at around 10m above the runway, and then pulled for a vertical climb right in front of me. As soon as the plane is vertical, the rudder/throttle is brought into the upper left corner, and the elevator/aileron to the upper right. The Hadron stops in midair, and start spinning after hesitating in a couple of what seems like uncontrolled rolls. The flat spin is fast from the beginning and keeps on accelerating....looks very impressive! But, as I was amazed by the performance of the little plane, I had forgotten that gravity was slowly calling the Hadron back to Earth, and it was time to snap out of it. Stopping the spin is easy: just center the stick, and the Hadron slows down, and eventually moves straight. However, the plane may loose some precious altitude, and on that first spin during my first flight, the Hadron recovered only a few feet above the ground! 

    Flight on 4S battery:

    On a 4S, the extra energy stored in the battery is absorbed by the motor which turns it into exhilarating velocity that will please all the speed enthusiasts! The Hadron is noticeably faster, and screams on full throttle. I recommend having a low rate setup on your radio to make the flight very smooth and help keep the turns long and clean. The maneuvers the Hadron could perform on 3S are all feasible on a 4S, only faster and even more impressive!

    The motor pulls a higher current, which for a same capacity battery means shorter flight. I recommend keeping the flight under 5 minutes with a 2200mAh 4S, to prevent from depleting the battery in its entirety.


    Belly landing the Hadron is extremely easy, and actually quite fun. My favorite landing is to bring it in with some speed on a freshly cut lawn and watch it slide for several yards!

    The Flyzone Hadron

    The Hadron brings fun and speed to the very competitive flying wing market. By adding particle-like speed capabilities and vectoring thrust features right out of the box, Flyzone manages to differentiate themselves from the competition.

    The Hadron is well designed, robust, and very capable. Minor defects can always be found, and the nose attachment weakness I noted earlier will not compromise the fun, and will be quickly forgotten once the plane is airborne.
