is known to have termed the phrase "Quick Build" to
describe a high level of prefabrication with their ARF
models. A QB descriptor in the title of an Aeroworks
ARF indicates that the model will have a good amount
of the assembly such as pre-drilled motor mounts, hinged
control surfaces, drilled cowling, etc... done right
out the box. Staying true to this description, Aeroworks
has now introduced its first airframe with the moniker
QB-L. The -L indicates that the model will arrive with
all of the features of a QB aircraft but in addition,
special attention has been paid to making the aircraft
as light and strong as possible.
The first QB-L airframe that has been released by Aeroworks
is the ever popular Extra 260 in a 52" wingspan that
is targeted specifically for electric power systems.
The Extra 260 QB-L carries with it a long list features
that sport and 3D pilots desire such as strong but light
carbon landing gear, control horns and main tube, air-foiled
control surfaces, quick release canopy for quick battery
changes, a generous area to accommodate various sizes
of batteries and last but no least SFGs in both wingtip
and inboard positions. The QB aspect of the Extra
260 includes features such as hinged control surfaces,
pre-drilled cowl and a motor mount that is ready to
accept a variety of popular power options that is surely
to get you out of the garage and in the air as quickly

"Light" aspect of the Extra 260 QB-L will become apparent
as you start looking over the fuselage and the perfectly
laser cut parts that have an abundance of lightening
holes. The canopy is held on with a turn screw that
is very easy to remove and attach. The latching mechanism
should make sure that the dreaded canopy blow off

nice feature can be found in the horizontal stabilizer
where an alignment pin has been installed to make
installation and alignment of the tail easier on the
modeler. Covering has already been removed from the
stabilizer and all that is required is a bit of work
to align and CA the assembly in place. The carbon
landing gear should help in reducing the overall weight
of the Extra 260. The sturdy tail wheel will bolt
on to the bottom of the airframe to help absorb the
shock from those harrier landings. Only a handful
of parts and a few hours of assembly is all that stands
between you and the airfield.
has some of the best manuals in the industry and the manual
of the Extra 260 QB-L does not deter from this statement.
A detailed manual that covers the quick assembly process
in a step by step manner is provided inside the box to get
the assembly process going. The manual calls out the
C.G. point along with the recommended throws on all surfaces.
To help setup the control surfaces, three throw meters are
included with the ARF which is a nice touch.
assembly process of the Extra 260 QB-L starts in the usual
ARF fashion by going over the covering then hinging the ailerons.
The CA hinges have already been slotted and inserted for
you so all that remains is to make sure that they are
centered and set them in place using a few drops of thin
the ailerons, I have chosen to use the recommended Hitec
HS-65MG servos. I chose to use a 3" extender which eliminates
the need for further extenders on the receiver as the
lead then becomes long enough to reach the receiver inside
the fuselage without any issues.
servo is then mounted in place using the hardware provided
with the servo.
control horns and push rods can then be installed per
the manual. The control horns that are supplied with the
kit are advertised as being lighter and stiffer carbon
arms. They fit perfectly in the pre-slotted area on the
aileron and all that is required is to slightly sand the
surface and set them in place using medium CA. The push
rods utilize ball links on both sides making the connection
ultra smooth and slop free.

side force generators are installed next. The installation
of the inner SFGs require a small section of covering
to be removed from both the top and bottom of the wing.
The SFGs then simply slide in place. The outer SFGs are
held in place using 4-40 bolts and bonded washers.
the wings completed, the focus of the assembly shifts
to the tail section. The single piece elevator is routed
through the opening in the fuselage before the horizontal
stabilizer is inserted. The horizontal stabilizer utilizes
a locator pin to make sure that the stabilizer is centered
in the fuselage. The manual explains the process of aligning
the stabilizer in great detail and once the stabilizer
has been centered, thin CA is used to set it in place.
I also hinged the elevator at this point and made
sure that I was getting the advertised 60 degrees of throw
before I set it in place using thin CA.
tail wheel is then inserted and glued in the pre-drilled
and slotted section in the rudder. The rudder is attached
to the fuselage using three CA hinges and set in place
using a few drops of thin CA. The tail wheel assembly
is then affixed to the fuselage using three wood screws.
the elevator, I chose to use the HS-82MG that is recommended
for the ARF which installs in the pre-cut bay in the tail
without any issues. I used a 12" servo extender to
reach the receiver and mounted the servo in place. The
control horn and push rods can then be installed and the
throws checked. The rudder utilizes a pull-pull setup
to get weight off the tail. I used another HS-82MG servo
inside the fuselage and routed the rudder cable through
the openings in the fuselage to make the connections to
the control arms. Ball link connectors are used throughout
to get a nice and tight connection to the rudder which
allows for full deflection in either direction.
main landing gear is then installed by attaching the axles
to the carbon landing gear. The wheels are held in place
using wheel collars on each end and the whole assembly
is then attached to the fuselage. The wheel pants simply
slide on and are locked in place using the pre-drilled
locations using a 4-40 bolt that bolts to a pre-attached
lock nut in the wheel pant.

this review, I was supplied with the Hacker A30-12XL
a 70A ESC which is one of the recommended power systems
that will help keep the overall weight as low as possible.
of the unique features of the Extra 260 QB-L is the pre-drilled
motor mount locations and the wooden spacers that help
in setting the perfect distance of the spinner back plate
to the cowling. The Hacker installation required 5 spacers
to be utilized. I trimmed the mounting bolts to make sure
that there were no sharp edges which could pierce the
battery in case of a mishap.
ESC is then mounted to the bottom of the motor mount and
held in place using double sided tape and Velcro ties.
A cooling duct is attached over the ESC to help route
air over it and keep it cool.
installation of the cowl is very straight forward and
utilizes 4-40 bolts and bonded washers. The use of bonded
washers through out the assembly is also a big plus when
it comes to making sure the bolts stay tight but at the
same time do not damage the component that they are holding.
cowl being pre-drilled was a nice touch and lined up perfectly
giving me a very small gap between the spinner and the
front of the cowl. The recommended 13x6.5 prop is can
then be installed using the provided white spinner. The
C.G. point is conveniently placed right on the wing tube
and a handy balancer is provided with the ARF to check
overall balance. With the 4S2800mAh flight battery installed
mid point in the battery tray, I was able to get perfect
balance as recommended in the manual. The Extra came in
right around 54 oz without the flight battery which was
in the advertised range for this airframe.
the assembly nearing completion, I binded my Futaba T8FG
to a 617FS receiver and mounted the receiver to the vertical
support of the battery tray. Using this location, I was
able to connect the aileron leads without having to use
additional extenders. The wings are held on using a single
bolt on each side. To complete the assembly, a cooling
hole is cut in the bottom of the fuselage and the Extra
260 QB-L is ready to be setup and taken out to the field.
provided control throw gauges come in very handy when
setting up the recommended triple rates in the manual.
I was able to achieve all of the recommended rates using
the triple rates feature of my Futaba 8FGS without any
the maiden flight of the Aeroworks Freestyle Extra 260 QB-L,
we headed out to our usual weekend hangout at Scobee field
on a calm and comfortable fall day. Having a convenient
52" wingspan, the Extra 260 QB-L is small enough to be transported
without having to take the wings off but can be broken down
by simply removing the wing bolts and aileron servo leads
at the field, we double checked the control surface, the
C.G. and the throws before heading out to the runway for
the maiden flight. Ground handling with the steerable
tail wheel did not present any issues and I was pleased
with the amount of control the Extra provided on the ground.
With a freshly charged 4S2800mAh flight battery, I lined
the Extra 260 QB-L in the center of the runway and increased
the throttle and watched as the Extra picked up speed and
lifted gently off the ground.
airborne, I proceeded to switch to mid rates and gain some
altitude and trim the airframe. My immediate reaction to
how the Extra 260 QB-L handled was very positive. I felt
a strong connection to the airframe and was comfortable
enough to try a few low passes without fear of a stall.
Rolling the Extra inverted, I was pleased to see the airframe
pull through without a drop of the nose which indicated
the C.G. was right on spot for my flying style. As I rolled
the Extra on its side and attempted a few knife edge passes,
I was pleased to find how little coupling the Extra exhibited
and was immediately able to notice how much lift and control
the SFGs provided. Within a few minutes, I was performing
low and slow knife edge passes over the runway in complete
confidence that the Extra would pull through without any
found that the recommended low rates could be reduced even
further to allow for more control in the precision department
as I continuously over controlled the elevator and rudder
while trying to make precision maneuvers. After reducing
the low rates a touch, I was pleased to find the Extra 260
QB-L tracked straight and true through loops, rolls,
hammer head turns and various other maneuvers I put it through.
I was especially pleased with the Extra 260 QB-L in its
capability to flat spin in both the upright and inverted
coming out of an inverted flat spin, I switched to high
rates and attempted and elevator to loose some altitude
and bring the Extra in low and close over the runway. I
was very pleased to see that there was minimal wing rock
in the upright orientation and was able to harrier the Extra
around with ease and total confidence. To transition to
a hover, I had to give a burst of power which brought the
nose up vertical and I found that I was over controlling
the rudder again as I initially struggled to keep the Extra
perfectly still. On later flights, I increased the rudder
exponential which helped greatly in achieving easily controllable
hovering maneuvers. I also noticed that there was minimal
torque induced by the motor while hovering which can be
easily countered by the large throws provided by the ailerons.
maneuvers were a pleasure to perform with the Extra 260
QB-L. I really like the way an Extra looks while doing rolling
harriers and this Extra did not disappoint. Inverted harriers
were virtually rock stready and the Hacker A30-12XL provided
enough power to rocket the Extra back in the sky in any
sign of trouble. On subsequent days where the field was
flooded from heavy rains, I particularly enjoyed flying
the Extra over the flooded areas as I attempted to dip the
rudder in the water.
it comes to landings, the Extra provides a nice glide ratio
and can come in with power off to settle on the mains without
any issues. Flight times with the 4S2800mAh battery were
in the 7-8 minute range which was long enough to provide
for a mix of precision and 3D flying.

(Pilots, Stills & Video: Burc Simsek and
think that the Freestyle Extra 260 QB-L is a great new addition
to the offerings that are available from Aeroworks. The
QB-L aspect of the airframe seems to provide a good balance
between all up weight and airframe strength as the Extra
exhibits a flight characteristic that is floaty when it
comes to 3D but carries enough mass to help track through
precision maneuvers as well. I think it provides the perfect
mix of sport, precision, and 3D which is rare in an airframe
of this size. I am usually not a big fan of how SFGs look
on an airframe however I think that the size of the provided
SFGs are just about right and I can tell that they really
do work. One of the more impressive maneuvers that can be
performed with the Extra 260 QB-L is small radius flat turns
both upright and inverted which are no doubt aided by the
was very pleased by the looks and the performance provided
by the Freestyle Extra 260 QB-L and can easily say that
it has earned its place in my hangar for months to
come. In the meantime, I look forward to what Aeroworks
have up their sleeve with regards to the new QB-L build
