This instruction manual is designed to help you build a  great flying aeroplane. Please read this manual thoroughly 
before starting assembly of your 

PITTS

. Use the parts listing below to identify all parts.

Please  trial  fit  all  the  parts.  Make  sure  you  have 

the  correct  parts  and  that  they  fit  and  are  aligned 

properly  before  gluing!  This  will  assure  proper  

assembly.

 PITTS 

ARF is hand made from natural materi-

als, every plane is unique and minor adjustments may have 

to be made.  However, you should find the fit superior and  

assembly simple.

The painted and plastic parts used in this kit are fuel 

proof. However, they are not tolerant of many harsh 

chemicals  including  the  following:  paint  thinner,  C/A 

glue accelerator, C/A glue debonder and acetone. Do 

not let these chemicals come in contact with the colors 

on the covering and the plastic parts.

assembly. Cover your workbench with an old towel or 

brown paper, both to protect the aircraft and to protect 

the table. Keep a couple of jars or bowls handy to hold 

the small parts after you open the bag.
