General Assembly Instructions

Thank  you,  for  purchasing  this  Stevens 

1911 Caudron  Racer

.

 

This  product  has  been developed  and 

manufactured using  state of  the art CAD/CAM systems  and features  a unique interlocking construction 

process  that,  when  compared  to traditional methods  found in other  model aircraft  kits,  save countless 

hours  of measuring,  cutting, sanding, and fitting.    We are  certain that  you’ll find our  kit  to offer  a  truly 

exceptional build experience.  As this  kit is  recommended for the novice model builder and pilot; we invite 

beginners  who have purchased this  kit  to seek  the  help  of a seasoned builder  and  pilot.   At any  time 

should one run across  a term or  technique that is  foreign please don’t hesitate to contact our staff with 

your questions.  

READ THIS!

Please 

READ

  and 

RE-READ

  these  instructions  along with  any  other  included  documentation  prior  to 

starting your build and/or contacting our staff for builder support.

Pre-sanding

Do not skip this  step.   Prior  to removing  any  parts  from the  laser  cut sheet wood use a sanding block 

loaded with 120-240 grit paper  and lightly sand the back  side of each sheet of wood.  This  step removes 

any residue produced as a result of the laser cutting process and, as  we have found that most stock  wood 

sizes run several thousandths of an inch over sized, slightly reduces the thickness of each sheet.

Leave your pre-sanded parts in the sheet until required in the assembly process.

Protecting your worktable

Use  the poly  tube  that  this  kit was  shipped in as  a non-stick  barrier  between your  worktable  and  the 

product assembly.  Promptly clean up any epoxy spills with rubbing alcohol and a disposable towel.

Bonding the assembly

As this  product tabs, notches, and otherwise interlocks  like a 3D puzzle we suggest that when fitting parts 

you dry fit (use no glue) the parts  together  first.   It’s  advised to work  1-2 steps  ahead in the instructions 

using  this  dry-fit technique  which allows  ample opportunity  to inspect  the fit  and location of assembled 

components  and realizes  a benefit  as  each  successive  part contributes  to pulling  the  entire assembly 

square.   Once you  arrive  at the end of a major  assembly sequence  square your  work  on top of  a flat 

building table and revisit the dry fit joints with glue.  Using the dry-fit process you’ll be able to recover from 

a minor build mistake and will ultimately end up with a more square and true assembly.  

Unless otherwise noted in the instructions  we find it easier to tack  glue part (temporarily bonding parts  in 

assembly using a small dot of glue) using medium CA glue applied with a fine-tip CA glue applicator tip.  

Tight fitting joints should be bonded using thin CA glue applied, sparingly, with a CA glue applicator tip.

Never force the fit!

Remember this  is  a precision cut kit our machines  cut to within 5 thousandth of an inch in accuracy.    Yet 

the wood stock  supplied by the mill may vary in thickness  by up to 20 thousandths.   This  variance in the 

wood stock  can cause some tabs/notches  to fit very tight.   With this  in mind, consider lightly sanding, or 

lightly pinching, a tight fitting tab rather  than crushing and forcing your  parts  together.  You’ll break  fewer 

parts in assembly and will end up with a more square and true airframe.
