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.
