aser 200 aircraft have a rich
heritage! The original may be
best known for the fact that
Leo Loudenslager won seven United
States Aerobatic Championships
between 1975 and 1982 in his. He
also stood on top of the podium in
1980, winning the World Aerobatic
Championships flying his Laser 200.
The Laser originated as a
Stephens Akro, but was completely
modified and redesigned by
Loudenslager to have a forward

fusealge, as well as new wings, tail
surfaces and cockpit. His Laser 200
was lighter weight, stronger and had
a more powerful engine, so he could
fly more difficult maneuvers.
The Laser was capable of letting
Loudenslager fly tumbling and
twisting maneuvers, but also more
precise aerobatics. His airplane has
had a significant influence on today’s
generation of aerobatic airplanes,
including the Extras.
Leo’s Laser 200 now hangs in the
Boeing Aviation Hangar at the Steven
F Udvar-Hazy Center as part of the
Smithsonian National Air and Space
Museum in Chantilly, Virginia.

What attracted me to the
AeroWorks Laser 200 30cc ARF was
its fidelity to scale, quality of build
and affordability.
If you compare the AeroWorks
Laser to the aircraft hanging in the
museum, you’ll see AeroWorks’
Your AeroWorks Laser 200
will come with the fuselage,
wings and stabilizers covered,
and the cowl is painted to
match. It uses very high
quality wood throughout.
The attractive, scale design
lines of the AeroWorks Laser
200 are complimented by
our beautiful cover model Liz
Jackson. The Laser sports a
76-in. wingspan.
We like that the
bottom of the
wings are done in
a contrasting color
scheme, which makes
for excellent in-air
visibility. Notice the
carbon wing joiner.
AeroWorks provides a complete hardware package for their Laser 200. It even
includes their CG Buddy and a nice set of decals.

The linkages that come with the AeroWorks Laser 200
provide an excellent fit to the airplane. You may want to
use longer servo arms if you are into 3D flying.
These are some of the supplies that you’ll
want to have on hand for building this
model. You’ll want some CA glue as well.
You can get all from towerhobbies.com.
The aluminum landing gear comes with
fiberglass wheel pants, plastic gear cuffs
and a set of lightweight wheels — it is a
high quality gear set.
The DLE 35 is a good fit
for the Laser 200. We had
no trouble fitting it to the
model, and getting it set up
for the carburetor to marry
with the throttle servo.
As you can see, the DLE 35 is a
rear exhaust design, and with a
rear intake carburetor. You will
like the fit and finish of this
motor and its ease of mounting.

package from AeroWorks.
designers have gone to some lengths
to do their research and to design
a model that is nearly 100 percent
accurate to scale. Then too, having
built other AeroWorks kits I knew
I would be getting a model that
was well built, with an exceptional
hardware package included.
Furthermore, the AeroWorks manuals
are some of the best in the industry,
which is to say they take you as
the modeler through the build in a
step-by-step fashion — they even
provide a DVD that includes the
manual and lots of photos detailing
the build. While I think, giant-scale
airplanes are outstanding to look at
and to fly, I liked the idea of building
this 1/4-scale model because it is
much more affordable to outfit with
engine, radio system and batteries.
In the case of my model, I bought
the DLE engine and Falcon propeller
from AeroWorks. I used Hitec RCD
servos, which were purchased from
Tower Hobbies. Also, I had the new
Hitec RCD Aurora 9X transmitter,
with an Optima 9 receiver, so it was
enlisted for this project. All in all, this
was a very affordable model to buy,
outfit and quick to build too.

The pull-pull control system for the rudder is a
straightforward install. Be certain to make sure the cables
are taught, without any slack, for best control response.
Notice, how clean the installation is for the ailerons. We
especially like the metal control horns and ball links that
AeroWorks puts in their kits.

AEROWORKS 30CC LASER 200 ARF
My model uses Hitec
RCD control gear
throughout, including
an Optima 9 receiver.
The transmitter is the
new Aurora 9X, which is
very easy to program.
This is what my final radio install looked like when it was
done. Building this model was a ton of fun because all the
parts fit well as per the instruction manual...
Here you see how the engine mounts to the firewall by
way of the aluminum standoffs. Also, notice how the
throttle linkage gets attached to the carburetor.
I ran the choke’s push-pull rod up to the front of the cowl
as shown. You can also see how the muffler gets attached
to the back of the engine and exhausts out the bottom.
I opted to use Fromeco battery packs in my model
because they are high quality and high capacity — 7.4-volt
2600-mAh Lithium Ion cells.
ARF ASSEMBLY
Like I said, AeroWorks’ instruction
manual steps you through the build
exceedingly well... You will not be
forced to guess at specific steps
in the model’s assembly. If you
follow the instructions one step at
a time, you’ll be rewarded with an
airplane that is fun to assemble and
outstanding to fly.
There are two areas of my
model’s assembly that I want to
expound on: the throttle servo install
and the alignment of the tail feathers.
Let’s start with the throttle servo.
While, the throttle servo’s plywood
tray is designed to glue to the side of
the fuselage just above the plywood
gas tank tray, I did not look closely
enough at the photos to see that
it does not glue to the the tank’s
tray, but rather just above it. This
generated a bit of problem for the
throttle’s linkage. As a result I had
to open the hole in the firewall a bit

RC SPORT FLYER . MAY 2014
more than is shown in the manual
in order to make for a friction-free
linkage run between the carburetor
and the servo. I recommend you
drill the hole in the firewall, align the
servo’s control arm with the throttle
linkage and then glue the servo’s tray
in the appropriate position on the
side of the fuselage.
The model’s tail feathers are
strutted by wire braces. This makes
for an exceptionally strong horizontal
and vertical stabilizer install, but if it
is not done properly, you will end up
with warped surfaces.
I recommend you enlist another
individual to help — even if their job
is getting the beer for when you’re
done. The reason for the extra
warm body is to help with holding,
tightening and loosening support
wires. You’ll need to continually
measure for perpendicular alignment
between the horizontal and vertical
stabilizer, as well as to make certain
Here is how I cut my
Laser 200’s cowl to
fit the DLE 35 engine
and muffler. Notice
the plastic exhaust
extensions have been
attached at this point.
none of the control surfaces get
warped or pulled out of shape.
Note the support wires utilize
both lefthand and righthand threads,
so as you turn a support wire it
will either tight or loosen, pulling
or pushing its respective control
surfaces. I found it rather enjoyable
to do, because I really get into
tweaking things until they are dead
on. In the case of the Laser 200,
I think it took my friend and I the
better part of 90 minutes to get the
empennage parts aligned properly.
I suggest you sight from the rear
of the model often to make certain
you are not pulling warprs or twistes
into the stabilizers. It is not hard. It is
time consuming!
Also, I would recommend that
you be certain to dial down all the
travel volumes in the radio prior to
energizing the radio receiver. This
will assure that no control surface is
overstressed, or that a servo is forced

A Falcon 18 x 8 wood
propeller provides the
thrust for the Laser. It
is covered by a TruTurn
aluminum spinner that I
painted with RustOleum gloss apple red.
You’ll want to put a
pilot in your model. In
this airplane, I’m using
a Hangar 9® 1/4-scale
pilot bust ((HAN9125).
It is a perfect fit for the
1/4-scale Laser 200.

into a stalled position, which could
otherwise damage it.
About the only other thing that
I would say about this build is to
be meticulous about making the
template for cutting the cowl. In so
doing, you will get a cowl that fits
the engine well, with enough airflow
to keep the engine cool in all flight
regimes.
Other than these items, I repeat,
the assembly of the Laser 200 is a
matter of follwing the manufacturer’s
instructions pretty much to the letter.

The weather here in “The Great
Northwest” has not be conducive
to model airplane flying, with winds
blowing nearly every day for the last
couple of months and rain part of
the time. FYI, some slope soaring
enthusiast pilots came to town two
weeks ago. They enjoyed winds from
30 to 62 mph.

AURORA
9X
I chose the Aurora 9X
transmitter for controlling
my AeroWorks Laser 200 because it has
nine channels of control, flight modes,
ultra smooth gimbals, five flight
switches, three trimmers and two
sliders. It is also lightweight and fits
my hands very well.
I outfitted the airplane with the
Optima 9 receiver because it handles all
the control functions of the Laser, with
a couple of spare channels left over.
Airplane Set Up
The Aurora 9X is set up to use the
airplane programming configuration.
The Laser was therefore programmed
in the System menu to have two
ailerons and a normal tail.
I have the ailerons programmed to
be on channel one and five, with the
elevators on two and six. The throttle
is set to be channel three and rudder is
four. It is a straightforward set up.
Programming
You’ll need to reverse channels one
and five for the ailerons, with all other
controls being normal.
The subtrimming required for my
Laser 200 was nearly zero. The one
elevator required 6 steps while the
other needed 37. In the future, I will
try to dial this subtrim out completely
by doing more mechanical adjusting,
however, the servo arms are aligned
with each other properly now, so it
may not be possible. Alternately, I may
use my Hitec RCD servo programmer
to adjust elevator number two’s center
position. For now I’ll fly it with the 37
sub-trim steps.
I’ve programmed the ailerons’
and rudder’s end points to be 125%.
The elevator’s EPA is 130%, while the
throttle is set to 55% high and 85% low.
Note that the dual rates for vthe
ailerons is set to: 65% for low with
-25% expo, 100% and -60% for mid, and
110% and -45% for high. The elevator is
programmed for: 24% and -25% expo
on low, 38% and -45% expo on mid, and
100% and -60% on high. The rudders’
control is set to: 39% and -25% on low,
68% and -45% on mid rate, and 116%
and -60% on high rate. We’ll see how
these settings work out once I’ve had a
chance to fly the model.
You’ll need to note that the
exponential is a negative value in
the Aurora 9X. If you program it as a
positive value you are going to have
very sensitive control at the sticks’
center positions, so make certain your
values are programmed negative. You’ll
be able to see a graphic representation
of the exponential at the dual-rate/
exponential programming screen.
I’m not using any Offset (OST) for
this airplane for any of the controls.
Note that I have the Throttle Lock
set on switch F. Forward is on and
back is off. Also, I’ve not set a throttle
curve yet, but I suspect that once the
airplane has been flown I’ll be setting
one using the seven-point curve that is
built into the Aurora 9X.
At this point I’ve not programmed
any flight modes or such into the
transmitter either — will do it later.
Finally, I set switch H to be the
Throttle Cut switch. I recommend you
do the same for you model, so that in
the event of problem with the airplane
you can kill its engine quickly if the
need happens. It is a huge safety issue
and one you don’t want to overlook.
I think you will enjoy controlling
your Laser 200 with an Aurora 9X. For
