General Tips: 

We recommend that you follow the general order of construction shown in this manual for 
the fuselage, as it makes access to everything easier and saves time in the end. The last 
item to be glued in position should be the Fuel tank mounting plate, as it makes access to 
the  rudder  tray  and  exhaust  system  less  easy.  The  wings  and  stabs  can  be  done  at 
almost any time, and only need servos installing anyway, as the control-surface horns are 
factory-installed for you. 
 
The  first  thing  to  do  is  protect  the  finished  paint  on  the  outside  of  the  model  from 
scratches and dents during building - so cover your work table with a piece of soft carpet, 
cloth  or  bubble-plastic.  The  best  way  to  stop  small  spots  of  glue  getting  stuck  to  the 
outside of the fuselage is to give the whole model 2 good coats of clear car wax first, 

but 

of  course  you  must  be  sure  to  remove  this  100%  properly  before  adding  any  additional 
decals  or  markings.  If  you  prefer  you  can  cover  the  majority  of  the  fuselage  with  the 
bubble-plastic used to pack your model for shipping, fixed with paper masking tape, which 
also protects it very well. 
 
When  sanding  any  areas  of  the  inside  of  the  fuselage  to  prepare  the  surface  for  gluing 
something onto it, do NOT sand right through the layer of glasscloth on the inside foam 
sandwich ! It is only necessary to rough up the surface, with 60/80 grit or equivalent, and 
wipe off any dust with alcohol (or similar) before gluing to make a perfect joint.  
 
Before  starting  construction  it  is  a  good  idea  to  check  inside  the  fuselage  for  any  loose 
glass fibres that could cut your hands, and a quick scuff over any of these with a coarse 
Scotchbrite 
pad will remove them. 
 

Note: 

It is 

very important 

to prepare the inside of all composite parts properly, by sanding 

and 
cleaning  the  surface  with  de-natured  alcohol  or  equivalent,  before  gluing 

any 

parts  to 

them.
