The full scale
turbocharged SR22T with features such as the Cirrus Airframe Parachute
System, the built in Oxygen System, 60/40 Flex seating for up to 5
persons and seatbelts with airbags, is one of the most prestigious full
aircraft that is available to a very lucky few with the financial
means to purchase and maintain an aircraft of this caliber. For the
rest of us, there is the Great Planes SR22T ARF which successfully
replicates the features of its full scale counterpart for a very
pleasurable building and flying experience.
The Great Planes SR22T is marketed as a sport scale ARF which only
requires a short few hours of assembly time to get it ready for flight.
The SR22T can be powered by your choice of 2 or 4 stroke glow
engine or and electric brushless motor. The required components
for both, such as the engine/motor mount and gas tank are supplied with
the ARF. The elegant fuselage of the SR22T is modeled in fiberglass and
arrives from the factory in a black and red paint scheme. The ARF
arrives with many money and time saving features such as pre-routed
linkage guides, pre-hinged flaps and ailerons. The SR22T also arrives
with navigation and landing lights that have been installed at the
factory and the leads wired through the wings for the navigation
lights. As a bonus, the pictured slick aluminum spinner is also
included with the ARF.
first thing that will grab your attention as you unbox your new SR22T
will no doubt be the beautiful fiberglass fuselage and assembled canopy.
canopy is held in place with two screws in the rear and two dowels in
the front. There is a gargantuan amount of space in the fuselage for
mounting your flight battery, receiver and various other components.
canopy features a detailed dashboard sticker along with a convenient
cut out in the bottom to allow access for mounting pilot figures.

This model operates with either glow or electric power depending on
your personal preference. Pick glow for more realistic sound or
electric for ease of installation and maintenance.
Many assembly steps are already completed to get you into the air more
quickly. The fuselage is pre-painted fiberglass, the wings align on a
joiner tube and attach with thumb screws and the flaps, ailerons and
rudder are pre-hinged.

business end of the fuselage features pre-drilled mounting holes for
the nose landing gear and either the electric motor box or the glow
engine mounts. A control guide has been routed in the fuselage to allow
for nose wheel steering. Also note the cut out on the front right hand
side of the fuselage to allow for glow muffler spacing when mounted
sideways. This will no doubt eliminate an unsightly cut out of the
fuselage and cowl. The distinctive looks of the SR22T is captured with
the provided aluminum spinner and fiberglass cowl. Notice that the
landing light has been pre-installed in a very professional manner. The
electric option will require you to open up the left air intake on the
cowl but will leave the graceful lines of the airframe intact. The
navigation lights on the wingtips have also been pre-installed and the
leads routed through the wings.
tail section features air foiled stabilizers and an aluminum joiner tube
is provided. Once assembled, the tail is no longer removable as all the
components will be glued in place. The wings on the other hand are
easily removable with over sized thumb screws and slide easily on the
provided carbon fiber wing tube. The flaps and ailerons have been
pre-hinged for you saving time and effort to get the SR22T ready for
its first flight. A few other bags contain the rest of the small
components that are required during the short assembly such as the motor
mount, landing gear, glow gas tank and engine mount.
assembly process of the SR22T is a relatively painless and quick task
given that the provided manual is very detailed and covers each aspect
of the build in great detail along with tips to achieve balance and
control throws. Preparation of the wings involves the installation of
four mini servos on the servo bay covers and making the connections to
the control arms via the pre-cut slots in the hatches. The main landing
gear can then be installed in the wing and the wheel pants attached.
The complete process takes no longer than an hour to complete.
completed wings are attached to the fuselage with the provided carbon
wing tube and anti rotation pins in the rear. A convenient cut out is
provided to route the aileron, flap and navigation light leads in the
fuselage. The plastic bolts that hold the wing in place are very easy
to manipulate due to their over sized nature.
servos for the rudder and elevator are installed in the fuselage and
the control linkages routed through pre-installed guide tubes. The
vertical stabilizer and rudder are integrated in the fuselage and
require no further assembly other than the connection of the control
arm to the rudder. The horizontal stabilizer has to be prepared by gluing
in the rudder hinges and anti-rotation pins and then the two halves are
glued to the fuselage using the provided aluminum joiner. A metal U-connector is provided
to join the elevator halves and allows for a single control arm to
nose gear takes a bit of trial and error to assemble correctly but
overall is a painless process. The nose gear is installed on the
provided strut and the fairing attached. A white sticker is provided to
cover the side so the overall assembly looks seamless. The gear is
attached to the fuselage and the steering control rod is attached to
the same servo that controls the rudder. This is a very simple yet
effective solution to providing a responsive yet slop free steering
control on the SR22T.
final bit of assembly involves the mounting of your power plant. For
this review, I have been provided with the O.S. 50 brushless motor which is one of the recommended power options listed in the
manual for the SR22T. The motor box is provided as a set of laser cut
parts and depending on your choice of motor, has to be finalized by
choosing the correct firewall. Notice the convenient ear on the side of
the motor mount to attach your ESC. A hole has to be cut in the
fuselage to route the wiring in the fuselage. Overall, the installation
is very easy and quick thanks to the generous amount of area that is
available to mount the components.
complete the SR22T, I used a Futaba FS617R receiver and completed the
wiring inside the fuselage with room to spare. The cowl and spinner are
then attached to the fuselage and a few decals attached to the
airframe. I was able to achieve the recommended C.G. with the provided
6S3300mAh LiPo flight battery mounted in its most rear-ward
a wingspan of 69", the SR22T is actually very easy to transport. I was
pleased to find that I could fit the airframe with the wings attached
in the back of my Xterra SUV. If you have to take the wings off for
transport, assembly at the field is quick as installing two wing bolts
and six servo extensions.
the day of the maiden flight of the SR22T, we had a stiff cross wind at
the field but that did not deter us from getting this beautiful airframe
in the air for some photo and video opportunities. Installation of the
recommended 6S3300mAh LiPo flight battery requires a small screwdriver
to remove the two bolts that hold the canopy in place. While this may
seem like a chore, it is good to know that the security of the bolts
will prevent the canopy from coming loose in flight and it does not
take more than a few seconds to strap down the battery and replace the
canopy. To achieve the recommended C.G., I installed the battery in its
most rearward position and noticed that I was still a tad nose heavy. I
made a mental note to move the ESC in the fuselage to help with this
and decided to carry on.
handling with the SR22T is superb thanks to the steerable nose wheel.
After taxiing the SR22T to the top of the runway and facing the wind, I
advanced the throttle carefully and was pleased that the SR22T was
tracking straight for its first lift off. As the airframe picked up
speed, it rotated gracefully and started to gain altitude. I did not
have to trim the airframe much to achieve level flight. Once in the
air, I flew a couple of quick circuits to try and familiarize myself
with the flight envelope of the SR22T and immediately noticed that if
flown too slow, the SR22T will drop its left wing quite quickly and
noticeably especially in tight slow turns. I gained some altitude and
repeated the test to see that the SR22T can easily recover from the
stall given that you nose down and apply some throttle to get the
airframe flying again. At full throttle the SR22T almost behaves like a
sport plane. It is fast and precise and the sound it makes as the thin
airfoil cuts through the air is very nice.
SR22T is capable of performing a set of basic acrobatic maneuvers such
as rolls, loops, stall turns and even some very nice snaps. To see a
scale airframe with a large wingspan and short fuselage perform a non
scale maneuver such as a snap and level out perfectly was a pleasure.
The SR22T can perform very nice point rolls and fly knife edge with
minimal coupling from the rudder which was very surprising to say the
least. Inverted flight requires down elevator to be held which is
expected. Even being a tad on the nose heavy side for the first flight,
I could not find much that I did not like about the flight
characteristics of this airframe.
it came time to slow the airframe down and attempt the first landing, I
deployed the flaps and noticed that the airframe did not really exhibit
any tendency to balloon as it carried on with a wider flight envelope.
With the flaps down, you can really slow the SR22T to crawl like
speeds. After flying a slow circuit with the flaps deployed, I reduced
the throttle on the downwind and made the final turn towards the
runway. The SR22T descends in a very controllable manner and it is
possible to make scale like touchdowns with the nose pointed up and the
mains touching down first. There is very little clearance between the
recommended 14" propeller and the ground. On one botched landing, I did
notice that the nose gear flexed enough for the prop to make contact
with the ground. Overall, landing the SR22T was a very enjoyable
process as I watched the great scale outline of the airframe make its
approach and glide in for a very smooth landing.
limited my first flight to seven minutes to see how much I would have
to place back in the battery and was pleased to see that I had not even
reached half of the 3300mAh rating which indicated that 10+ minutes of
flight will easily be achievable.
Great Planes SR22T ARF
Great Planes has produced another gem with the SR22T ARF.
The build quality of the airframe is top notch, everything fits
together perfectly and there is not much left for the modeler to
perform but a quick assembly of the ARF. The ARF arrives with many nice
touches such as the pre-hinged flaps and ailerons, pre-installed
navigation and landing lights and even the spinner is included. The
SR22T can be powered by glow or electric and there are nice cut outs on
the cowl and fuselage to accommodate the glow muffler.
assembled, the SR22T does a great job of replicating the sleek looks of
the full size airframe and in the air, it performs flawlessly. Field
assembly is quick and the SR22T can even be transported with the wings
attached depending on the vehicle you have. The flight envelope of the
SR22T resembles that of a sport plane where it is capable of flying
fast, performing a basic set of aerobatic maneuvers and slows down very
for a very controllable approach for landings.
the only thing I can suggest as an improvement would be to have a quick
release canopy to make the life of electric pilots easier when it comes
to changing the battery as the current hatch is held in place with two
bolts. Overall, I was very pleased with the SR22T and look forward to
the next opportunity that I will have to fly it.
