• A dimensionally deluxe flying wing with a preapplied crisp, futuristic,
military-inspired red, black, and gray graphics scheme.
• The included brushless power system can be fed with either an 11.1- or
14.8-volt LiPo battery, with nothing more than a quick propeller swap
• Thrust vectoring allows the Hadron to perform insane flat spins and
other extreme maneuvers.
• The airframe is reinforced with carbon rods in its wings and on the
• Molded-in-the-foam indexing marks simplify CG verifications and
proper battery positioning.
• Magnetically retained nose cone is easily removed and replaced,
should any less-than-perfect hand launches or landings crumple it.
• Although the quality is superb and the engineering is sublime, the
sticker price for this foam model may cause some modelers to raise an
AT A GLANCE ...
My Hadron’s all-up weight came in at 30. 8 ounces when
outfitted with a 3S 2,200 mAh LiPo battery, while a 4S 2,200
mAh pack bumped this weight up to 33 ounces. Running both
versions across my Eagle Tree eLogger yielded approximate
readings of 300 watts on a freshly charged 3S pack, and
slightly more than 500 watts on a 4S pack! Don’t forget to use
the smaller 5 x 5 propeller when running the 4S!
Given the Hadron’s lack of landing gear, I took it to my
favorite grass field for the first flights. I like not having landing
gear because it helps keep the loading on this airplane on the
lighter side. After range checking the Tactic radio
gear on-site and double-checking all control surface
deflections, I was ready to begin flight testing.
I like to use the timer function of the Tactic
TTX650 radio. The assembly manual suggests
countdown values of 3. 5 minutes when flying the
Hadron on a 3S LiPo and 3 minutes when flying it
on a 4S pack.
If you fly the Hadron from a hard surface,
Flyzone’s landing skid plates on the underside of
the flying wing will help minimize any damage to
the airframe when sliding across a concrete runway.
With a little practice, the Hadron can be landed
with practically zero ground speed. Before I can
discuss the landings, I probably should first get it
into the air! And getting the Hadron aloft requires a
There is no need to overthink the hand launch.
The Hadron has plenty of wing area and its power
system provides plenty of power. When launching
the Hadron, remind yourself to follow through when
releasing it. I mentally remind myself that my launch motion
should end with my hand aimed at the point toward which I
want the Hadron to be traveling when it leaves my hand.
The finger grips molded into the foam on the bottom of
the Hadron make it easy to get a good grip on the aircraft. An
alternate launch technique used on flying wings is one that
eliminates any chances of the propeller carving its way across
the back of your hand. Grasp the wing’s LE and use a side-arm
toss to throw it forward in an arc-like motion.
I set the vectored thrust mix to rudder only and use low
rates when launching. With the power at nearly full throttle,
