Congratulations on your purchase of the Extreme Flight RC 60 inch Laser EXP ARF!
I am a huge fan of the Laser 200 and the late airshow legend Leo Loudenslager. I always
knew that at some point Extreme Flight would have to produce a model of this iconic
airframe. My goal was to honor the unique legacy of Leo and his Laser while bringing the
model up to date to match the performance we have all come to expect from an Extreme
Flight EXP series aircraft.
One of the last modifications that Leo made to the Laser was to install a more streamlined
canopy. This canopy was installed on the Laser and flown by Leo prior to his tragic death
in a motorcycle accident. I much prefer the look of this canopy to the original and decided
to incorporate it into the Laser EXP design. In my research I found photos of the Laser
Z230, Laser 300 and 2000 that had all started incorporating much more streamlined
modern cowlings. I decided to incorporate a similar cowl into the Extreme Flight EXP
version as well. As such this model can't really be designated as any particular variant,
so I decided to simply call it the Laser EXP. Like all of the EXPs, the Laser excels at both
3D and precision maneuvers. It shares the long tail moment of the Extra and Edge which
gives it great stability in high speed precision maneuvers and it also features that famous
EXP elevator that allows for crazy pitch authority and great stability in high alpha
maneuvers. When the CG is properly set the Laser has minimal coupling and is a very
neutral aircraft.
The Laser EXP shares many of the attributes of the previous EXP airframes along with
some new features. Due to customer feedback we have changed the wing retention
method to make it much easier to attach the wings to the fuselage. The wings are also
slightly recessed into the fuselage sides which provide a much cleaner appearance and
insures the wings will appear flush with the fuselage sides. The Laser EXP incorporates
carbon fiber and G10 composites into the structure of the airframe, resulting in a
lightweight, yet twist free structure capable of handling extreme aerodynamic loads.
Carbon and G10 are used in high stress areas such as the landing gear mounting structure
and fuselage longerons to provide enormous strength and durability. A true piece of
carbon fiber art, the landing gear is airfoiled and has just enough "give" to cushion those
not so perfect landings. All control surfaces are pushrod driven with short linkages and
use ball links for slop free actuation with no binding. Optional Side Force Generators are
included and add to the already generous side area, increasing yaw axis authority and
adding stability in all angles of sideslip. Expertly painted fiberglass cowl and wheel pants
and 2 gorgeous high visibility Ultracote color schemes add the finishing touches and make
this an airplane that you will be proud to show up at the flying field with.

Tips for Success:
1. Before starting assembly, take a few minutes to read the entire instruction manual
to familiarize yourself with the assembly process.
2. Please take a few minutes and go over all the seams on the aircraft with a covering
iron on a medium heat setting. Also, due to climate changes, wrinkles may develop
in the covering. These are easily removed with a little bit of heat. Use a 100%
cotton tee-shirt and your heat gun and heat the covering while gently rubbing the
covering onto the wood with the t-shirt. Be careful not to use too much heat as the
covering may shrink too much and begin to lift at the edges. Take your time, and a
beautiful, paint-like finish is attainable.
3. Apply a bead of Pacer Formula 560 Canopy Glue at the intersection of the plastic
canopy and its wooden frame.
4. Take a few minutes and apply CA to high stress areas such as servo mounting trays,
landing gear mounts, anti-rotation pins, and motor box joints.
5. By the time your aircraft arrives at your door step, it will have been handled by a lot
of people. Occasionally, there are small dings or imperfections on some of the
surfaces. An effective method to restore these imperfections to original condition is
to use a very fine tipped hypodermic needle and inject a drop of water under the
covering material and into the ding in the wood. Apply heat to the area with a
sealing iron and the imperfection will disappear. Deeper marks may require that
this process be repeated a couple of times to achieve the desired result, but you will
be surprised at how well this technique works.
6. Use a high quality epoxy for installing the composite control horns. We highly
recommend the new Mercury Adhesives 30 minute Epoxy or Pacer Z-poxy. We are
very pleased with the results and ease of application and cleanup of these products.
7. When applying decals, first clean the area where the decal will be applied with
alcohol. Mist the area lightly with Windex or Rapid Tack before applying the decal
which will allow you to properly position it, and then use a rubber squeegee to push
all of the liquid from under the decal. This will result in very few air pockets
trapped under the decal.
8. Take the time to properly balance and trim your aircraft and set up rates and
exponential values. Your flying experience will be greatly enhanced once your plane
is properly dialed in.

Let's begin!
1. Locate the 2 wing panels as well as the composite aileron control horns and base
plates. Use a soldering iron or sharp hobby blade to remove the covering over the
slot for the aileron horn. Make sure you are doing this on the bottom of the aileron!
2. Insert the horn into the base plate and into the slot in the aileron. Use a fine
tipped felt marker to trace the base plate.
6
3. Remove the horn assembly and use a #11 blade to remove the covering from inside
the ink line you traced around the control horn base. Wipe away the ink line with a
cotton cloth or paper towel soaked in denatured alcohol.
4. Use sandpaper to scuff the portion of the horn that will be inserted into the aileron as
well as the bottom of the base plate.
7
5. Insert the control horn into the base plate and apply 30 minute epoxy to the slot
in the aileron and the scuffed potion of the control horn that will insert into the
aileron. Use a zip tie to ensure the slot is completely filled with epoxy.
6. Install the aileron horn into the aileron slot and wipe away any excess epoxy with a
paper towel or cloth soaked with denatured alcohol.
8
7. Remove the aileron from the wing to ensure all hinges are centered between the
wing and aileron. One way to ensure the hinges are centered is to fold them in half
and re-install into the aileron using the crease as a reference point.
8. Making sure the aileron is properly aligned between the wing root and wing tip,
hold the aileron fully deflected and apply a drop of thin CA to each hinge. Flip the
wing over and repeat.
