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.
Hadron is available in two versions:
ready version that will work with any SLT ready
- Receiver ready system. You will need your own
radio system, including a receiver.

the envelope to include violent spinning maneuvers

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

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
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.
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.

Hadron is a power-hungry guy that quickly transforms
electrons into speed. I tested the plane with 3
different batteries: the
30c 2200mAh (provided)
45c 2200mAh battery
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.
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.
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
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!
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.
