 2.  You must assemble the model 

according to the 

instructions

. Do not alter or modify the model, as doing 

so may result in an unsafe or unfl yable model. In a few 
cases the instructions may differ slightly from the photos. 
In those instances the written instructions should be 
considered as correct.

 3.  You must take time to 

build straight, true

 and 

strong

.

 4.  You must use an R/C radio system that is in good condition, 

a correctly sized engine, and other components as 
specifi ed in this instruction manual. All components must 
be correctly installed so that the model operates correctly 
on the ground and in the air. You must check the operation 
of the model and all components before 

every

 fl ight.

 5.  If you are not an experienced pilot or have not fl own this 

type of model before, we recommend that you get the 
assistance of an experienced pilot in your R/C club for 
your fi rst  fl ights. If you’re not a member of a club, your 
local hobby shop has information about clubs in your area 
whose membership includes experienced pilots.

 6.  While this kit has been fl ight tested to exceed most 

normal use, if the plane will be used for extremely high 
stress fl ying, such as racing, or if an engine larger than 
one in the recommended range is used, the modeler is 
responsible for taking steps to reinforce the high stress 
points and/or substituting hardware more suitable for 
the increased stress.

WARNING:

  The  cowl  included  in  this  kit  is  made  of 

fi berglass, the fi bers of which may cause eye, skin and 

respiratory tract irritation. Never blow into a part to remove 

fi berglass dust, as the dust will blow back into your eyes. 
Always wear safety goggles, a particle mask and rubber 
gloves when grinding, drilling and sanding fi berglass 

parts. Vacuum the parts and the work area thoroughly 
after working with fi berglass parts.

We, as the kit manufacturer, provide you with a top quality, 
thoroughly tested product and instructions, but ultimately 
the quality and fl yability of your fi nished model depends on 
how you build it; therefore, we cannot in any way guarantee 
the performance of your completed model, and no repre-
sentations are expressed or implied as to the performance 
or safety of your completed model.

NOTE:

  Some  technically-minded  modelers  who  wish  to 

check the wing, stab and motor thrust angles may do so by 

visiting the web site at www.greatplanes.com and clicking 

on “Technical Data.”

REMEMBER: Take your time and follow the instructions 
to end up with a well-built model that is straight and true.
