Thank you for purchasing 

The microHawk Capacitor-Power Motor Glider

 from Stevens AeroModel.  This model 

has been developed and manufactured using state-of-the-art CAD/CAM systems.  Our kits feature a unique 
interlocking construction process, that when compared to traditional building methods, saves countless hours of 
measuring, cutting, sanding, and 

fi

tting.  Also included in this kit are building 

fi

xtures which will aid in assembly, 

their construction and use will be described in the step by step build instructions. We are certain that you’ll 

fi

nd 

our kits to o

er a truly exceptional build experience.  

IMPORTANT!

Please 

READ

 and 

REREAD

 these build instructions along with any other included documentation before starting 

your build and/or contacting our sta

 for builder support.

Pre-Sanding (Optional)

Before removing any parts from the laser-cut sheet wood, use a sanding block loaded with 250 - 400 grit 
sandpaper and lightly sand the back side of each wood sheet.  This step removes any residue produced as a 
result of the laser cutting process.  This step also slightly reduces the thickness of each sheet of wood.  We have 
found that most stock wood sizes run several thousandths of an inch oversized.  Leave all parts in the sheet 
wood until required for assembly.

Protecting Your Work Surface

Use the poly tube that this kit was packed in to protect your work surface from the glues used during assembly 
of the model.

Bonding the Assembly

This product’s tabs and notches interlock like a 3D puzzle.  We strongly suggest that when 

fi

tting parts, you dry 

fi

t (use no glue) the parts together 

fi

rst.  It is advised to work 1 - 2 steps ahead in the instructions, using this dry-

fi

t technique.  This allows the opportunity to inspect the 

fi

t and location of assembled components, and shows 

the bene

fi

ts of our construction technique. Once you arrive at the end of a major assembly sequence, square 

your work on a 

fl

at work surface or by using the included assembly 

fi

xtures and bond the dry 

fi

t joints with glue.  

Using the dry-

fi

t process, you’ll be able to recover from a minor build mistake and will ultimately end up with a 

square and true assembly.

When using CA, apply glue with a 

fi

ne-tip CA glue applicator.  Unless otherwise noted in the instructions, we 

fi

nd 

it easier to “tack glue” parts (temporarily bonding parts in assemblies, using a small dot of glue).  

When using wood glue, apply a small amount of glue to the surfaces to be bonded. After assembly, pin your 
parts into place and allow them to dry throughly.

Sanding

Do not sand the individual parts of this model.  This kit is precision cut to assemble with the correct angles and 
incidences to ensure proper 

fl

ight performance.  If desired the laser burn may be removed after assembly. 

Never Force the Fit!

This is a precision laser-cut kit.  Our lasers cut to within 5 thousandths of an inch in accuracy.  Yet the wood stock 
supplied to us by the mill may vary in thickness by up to 20 thousandths.  This variance in the wood stock may 
cause some tabs and notches to 

fi

t very tightly.  With this in mind, consider lightly sanding or lightly pinching a 

tight-

fi

tting tab, rather than forcing the parts together.  You will break fewer parts in assembly, and end up with a 

square and true airframe.
