Greetings and congratulations on your purchase of the Extreme Flight RC

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

heritage 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. I was never a fan of the original cowling on the Laser. In my research

I found photos of the Laser Z230, Laser 300 and 2000 that had all started

incorporating much more streamlined and "sexy" 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. The motor box construction has been changed

to the style of the 60 inch EXP aircraft as it has been proven in these

airframes to be rock solid and easier to assemble in production. Due to

customer feedback we have also 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 provides a much cleaner appearance

and insures the wings will appear flush with the fuselage sides.

If repairs become necessary, the Ultracote colors used on the Laser EXP are

as follows:

True Red-part number HANU866 (Oracover #023 Ferrari Red)

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.

3. Use a fresh bottle of thin CA with a fine glue tip when attaching the CA

hinges. This will ensure that the proper amount of CA wicks into the hinge

and surrounding balsa wood and creates a proper bond between the wood and

hinges. We are big fans of the Mercury line of adhesives as well as the glue

tips provided by them.

4. Apply a couple drops of CA to high stress areas such as anti-rotation pins,

landing gear mounts, servo trays and motor box joints .

5. All of the G10 control horns are the same with the exception of the elevator

horn. Its base has been shortened to fit the depth of the elevator.

6. When applying decals, first clean the area where the decal will be applied

with alcohol. Mist the area lightly with Windex before applying the decal

which will allow you to properly position it, 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.

7. Take the time to properly balance and trim your aircraft and set up rates

and exponential values. Your flying experience will be greatly enhanced by

doing this.

Please note: The assembly of the Laser EXP is almost

identical to the assembly process of the previously

released Extra 300 EXP. Most photos will show the

Extra component assembly. Only assembly steps

which differ will show the Laser components.

Items needed for completion

-Masking tape

-Hobby knife with #11 blades

-Razor saw

-Thin and medium CA. We highly recommend Mercury M5T thin and M100XF medium

formulas as well as the Mercury glue tips.

-30 minute epoxy. The new Mercury adhesives Epoxies have worked very well for us.

-Blue Loctite.

-Silicon based glue (Zap-A-Dap-A-Goo, etc.)

-Electric drill with an assortment of small drill bits.

-Small flat head and Phillips head screw drivers.

-Standard and needle nose pliers.

-Metric balldriver or allen key set.

-4 sub micro metal geared servos. All flight testing was performed with Hitec HS-65MG

and HS-5065MG digital servos and we strongly recommend the use of either of these high

quality servos.

-Torque 2814T/820 Brushless Outrunner motor.

-Airboss Elite 45 Amp ESC.

-4S 2100-2700 mah LiPo battery.

-APC 12x6 E prop (NOT the slow fly version!).

-52mm Extreme Flight spinner.

-2 18"-24" extensions for the 2 rear servos and 2 6"-8" extensions to go between the

receiver and the aileron servo leads. We recommend the 28 or 32 AWG extensions to save

weight.

-Adhesive backed Velcro and Velcro strap for battery retention.

Let's begin!

1. Locate the 2 wing panels with ailerons as well as the 2 G10 aileron control

horns. Remove the ailerons from the wing and remove the covering over the

slot for the aileron horn on the bottom of the aileron with a sharp hobby

blade. Make sure you are doing this on the bottom of the aileron!

2. Scuff the portion of the control horn that will be glued into the aileron with

sandpaper.

3. Use a glue tip on your bottle of medium CA and apply glue to the slot as

well as to both sides of the control horn. Insert the control horn into the slot

and make sure it seats properly against the surface of the aileron.

4. Remove the covering from the aileron servo location and make sure the

hinges are centered in their slots.

5. Slide the aileron into position on the hinges and secure with several drops

of fresh thin CA. This process is much easier and more effective if a fine glue

tip is used. Make sure to deflect the surface as pictured while applying the

CA.

6. Use the screws provided by the servo manufacturer to secure the aileron

servo in the designated location. 1 screw installed in the center hole at each

end of the servo is adequate to secure the servo. Make sure the output shaft is

positioned toward the trailing edge of the wing.

7. Locate the 2 threaded pushrods that are the same size and 4 micro ball

links along with 4 2mm screws, nuts and washers. Thread the ball links onto

each end of the pushrods and secure to the servo arm and control horn with

the 2 mm hardware as shown in the picture. Use the longest arm provided

with your servo.

Repeat this process for the other wing half.



8. Locate the carbon fiber main landing gear, 2 axles, 2 washers, 2 locking

nuts, 2 wheels, 2 wheel collars and the 2 wheel pants from the hardware

package. Place the threaded portion of the axle through the hole in the

carbon gear, slide a washer over the threaded portion and screw the lock nut

onto the axle, but do not tighten completely. Place the wheel onto the axle and

secure with a wheel collar. There is a slot pre-cut in the wheel pant to allow

it to fit over the axle. Before installing the wheel pant place a drop of silicon

based glue onto the wheel pant just above the pre-cut slot. This will prevent

the wheel pant from rotating, but allow it to move in the case of a mishap

which may help to prevent damage. Slide the wheel pant into position over

the axle and tighten the nut on the axle, taking care to make sure the wheel

pant is positioned properly. Repeat this process for the remaining wheel pant.

Again this is probably better explained in the following series of pictures.
