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)
