the day it was released as a brushed sonic combat ready
F-27B airframe to when it was upgraded to the brushless
F-27C tiger meet scheme, the ParkZone Stryker has been
a favorite of many in this hobby ranging from beginners
to experts and is one of those airframes that can truly
be classified as a legend.
The new F-27Q version of the Stryker is a major re-design
of the airframe by Q. Q. Somenzini himself and includes
many improvements in both durability and performance.
Being a long time fan of this airframe and having purchased
and built from scratch countless F-27B/C airframes,
I was very thrilled to have the opportunity to get my
hands on the Q version for an official RCU review. Lets
unbox a BNF version, put it together and take it out
to the field...
F-27Q Stryker is shipped in a colorful box that is quite
nice to look at.
very few parts that are required to get the F-27Q Stryker
ready for flight are well packaged and I was pleased to
see that there was no damage to any of the components
all of the components removed from the box, you can see
that all that needs to be done is to install the rudders,
attach the nose and bind the receiver. The control surfaces
have been pre-hinged with CA hinges and the control rods
are supported by carbon rods to make them nice and stiff.As
this is the BNF version, the receiver has been attached
and all that remains it to bind it.

by world aerobatic champion Quique Somenzini,
the F-27Q Stryker delivers a thrilling blend
of speed and aerobatic precision that?s
unlike anything else in its class. Its fiberglass-reinforced
Z-Foam airframe has been designed to handle
abrupt wing loading changes at high speeds.
This, combined with its more powerful 480
brushless power system and twin rudders,
gives you an extra dimension of aerobatic
fun you won?t find with any other
flight-ready flying wing. Flat spins, blenders,
snaps, knife edge ? the F-27Q does
it all with the same smooth, predictable
handing that?s made every Stryker
a sport flying favorite.

familiar with the previous generation of the F-27B/C
Stryker will immediately start to notice all of the
differences that have been incorporated in the F-27Q
version as you remove the components from the box.
The nose cone which used to be a stick on deal has
been upgraded to a magnetic mount. Once attached,
it makes a pretty sturdy connection but at the same
time can pop off during a mishap to save the fuselage
from major damage. Another significant improvement
is the new magnetic canopy which covers the new enlarged
battery tray. The battery cover is held on by powerful
magnets in the front and with a latching mechanism
in the rear. the turtle deck design of the electronics
cover is also another nice improvement over the previous
design where the deck was held in place with plastic
nails that were attached directly to the foam which
usually wore out very quickly after a insertions.
The new turtle deck is held in place with a single
screw and removes/attachers quite easily. Underneath
the turtle deck, the pre installed AR600 and the 40A
ESC is visible. An extension has been pre-installed
to the bind port of the AR600 so you will not actually
have to remove the turtle deck at all to get the F-27Q
Stryker ready for flight.
of the major new features of the F-27Q Stryker is
of course the dual rudders. The control horns have
been pre-attached and a strip of dual sided tape is
provided to attach them to the fuselage. The wing
tips is another area where new features can be found.
A plastic cover wraps the wing tip to prevent against
damage and a wing fences have been molded in the fuselage
which according to the literature, serve to help in
stabilizing the Stryker when flying at higher speeds.
The leading edge of the wing also has a nice cut out
but I have not been able to figure out if it has been
added to serve a specific function or for looks. Either
way, they look great.
motor mount has also been redesigned and is now molded
in the fuselage. It is supposed to not only provide
a better platform to attach the motor to but to also
help in making the airframe more rigid. The bottom
of the fuselage now holds a single wheel and plastic
along the bottom of the fins. I am not super crazy
about the wheel as I probably would not land the Stryker
on a hard surface when grass is available but there
will surely come a time when I will try to shoot high
speed touch and gos by trying to bounce the Stryker
off the ground off the new wheel so I am looking forward
battery hatch (or canopy) has a very large cooling
hole in the front which should help get some air over
the battery and ESC to help keep them cool during
those high speed passes. Another major new feature
is the move to the outrunner 480 motor and the higher
pitch 6"x6" plastic propeller which is supposed to
help propel the F-27Q Stryker to higher speeds.
BNF version is shipped with a pre-installed AR600
receiver and a 3S2200mAh 25C LiPo battery and charger
that have pre-installed EC3 connectors. All of the
surfaces are actuated by metal geared DSV130M digital
manual contains information on how to assemble the F-27Q Stryker,
bind the receiver and setup the control surfaces. The CG point
is documented as 5.5" forward of the firewall which places
it right about the middle of the hand launch opening in the
bottom for quick reference.
that is required to get the F-27Q Stryker BNF ready for
flight is to attach the nose cone, bind the AR600 receiver
and install the rudders. The provided double sided tape
is all that I used to attach the rudders for a few initial
flights but the manual actually recommends that you use
some CA to help them stay on during high speed flight/maneuvers.
the rudders are installed, the two carbon fiber supported
control rods are installed and can be adjusted to center
the surfaces. The clevises are held shut by small pieces
of fuel tubing. I noticed that without the fuel tubing,
the clevises do not really like to stay on there very
tightly so it is probably best to check these before and
after each flight.
the spring and summer seasons in Houston are relatively
calm, albeit hot, and perfect for flying. However this last
season was day after day of windy conditions which did not
make for great conditions shoot video of the Maiden of the
Stryker. The Stryker however does not really care about
the wind as it cuts through it effortlessly and in my opinion
is actually even more fun to fly in slightly windy conditions
due to the higher speeds that can be achieved with a good
tail wind and the ability to perform inverted stationary
the photo shoot, we headed out to Scobee field in Houston
with two Strykers and got them both ready for flight. The
Stryker is very easy to launch in to the wind. I prefer
to apply about quarter throttle and give it a firm toss
in to the wind and lay on the power after it clears my hand.
The F-27Qs increased torque from the outrunner motor seems
to want to bank the Stryker sharply to the left when power
is applied abruptly so it is probably best to not
just nail it but to apply throttle gradually on takeoff.
the Stryker was up in the air, a few clicks of trim here
and there were all that was needed to achieve level flight.
Going to full throttle I immediately realized that the new
Stryker is a fairly bit quicker that the C version.
I would even go as far to say it performs close to a stock
C Stryker on 4S. I rolled the Stryker over and noticed
that I had to give a bit of down elevator to maintain level
course the maneuvers that I was very interested in performing
now that I had rudders were the flat spins and knife edge
flight. I setup for a high speed run over the runway and
banked the Stryker hoping to catch it with the rudder but
noticed immediately that the rudder has some roll coupling.
In fact, I was able to do a barrel roll on rudder alone.
I discovered that doing a nice knife edge does not actually
require a lot of rudder but more speed but eventually I
was able to perform an acceptable knife edge pass in both
directions which brought a grin to my face.
up was the flat spin. I tried for a while to get an upright
spin going but just could not manage to do it. The inverted
flat spin on the other hand is fairly easy to enter and
maintain by simply cornering the sticks after a blender
or when stalled at the top of a climb. You can spin fairly
flat down to a comfortable altitude but require a little
bit of recovery room on the bottom as you need to fly out
of the maneuver on the wing. As this was one of the first
couple of F-27Q Strykers in our field, several people came
out to the flight line to watch the flat spins and I could
hear laughs of amazement every time I performed these maneuvers.
high throws on the control surfaces coupled with the rudder
also allow for some nice snaps. It is really fun to start
a climb, perform a snap, come to a stop, then turn around
and fly the other way. I was very temped to try a parachute
but did not want to risk putting the review airplane in
the ground before I had a chance to finish the review. However,
the parachute and elevators (with some slight wing rock
in high alpha) are now among the repartuare of maneuvers
that you can fly with the Stryker.
always like flying inverted harriers with the older generation
of Strykers and the new F-27Q Stryker is no different. I
did not really utilize the rudders during inverted harriers
but felt like I could get slower, lower and higher alpha
harriers with the newer version that I could ever
more I flew the Stryker, I started to realize the new Stryker
is not only faster up top, but that it also allowed me to
fly at slower speeds which essentially translates in to
a wider flight envelope. I did notice a slight rocking or
yaw effect when approaching stall speeds when turning but
when using the rudder to make coordinated turns, this effect
flight times that I observed were less than the advertised
times of 8-12 minutes with my first flight running out of
power at around the 6.5 minute mark which seemed to be consistent
with further flights. During my second flight, I ran out
of power while trying to perform a low harrier pass but
was able to turn the Stryker upright and perform a pancake
landing from about four feet off the deck which did not
do any other damage than nick the prop.
one Stryker is fun, two or more is of course better, so
we handed the camera to a friend and took both the Strykers
up for some formation flying. It is always fun to try and
fly wingtip to wingtip in a slow pattern around the field
which yielded in some nice static photos which can be seen
out the video to see her in action!

you have never flown a Stryker before, you owe it to yourself
to try one out. The F-27B and the F-27C were both great
airframes which flew on inexpensive 2200mAh 3S LiPos, had
great performance out of the box and were open for extensive
modification to reach speeds well over a 100mph. On the
opposite end of the spectrum, the airframe could be slowed
down to provide a nice and relaxing flight allowing you
to achieve greater than 10 minutes of flight time. Parts
were inexpensive and you could build a Stryker from scratch
with a custom paint scheme. My favorite was to paint the
top yellow and the bottom black and to dress it up with
the F-27B stickers.
how does the new Stryker compare? Well I can safely say
that the new F-27Q Stryker promises performance and it delivers...
It is faster, more maneuverable, more aerobatic, includes
some well designed upgrades and flys great, really great. I'll
admit that when I first saw the media release of the new
Stryker back in April, being so used to the previous generation,
I was not really crazy about the new look but was intrigued
about the new features. The new look has now actually grown
on me while the performance and improvements over the previous
generation are a welcome addition and this will definitely
be an airframe that will make it to the back of my SUV every
time I go out to the field. Great job and thanks ParkZone!
