1.  If  you  have  not  done  so  already,  remove  the
major parts of the kit from the box and inspect for
damage.  If  any  parts  are  damaged  or  missing,
contact Product Support at the address or telephone
number  listed  in  the  “Kit  Inspection”  section  on
page 5.

2.  Remove  the  tape  and  separate  the  ailerons  and
flaps from the wing and the elevators from the stab.
Use  a  covering  iron  with  a  covering  sock  on  high
heat  to  tighten  the  covering  if  necessary.  Apply
pressure over sheeted areas to 

thoroughly 

bond the

covering to the wood. 

When  ready  to  fly,  you'll  need  some  additional
equipment  to  fuel  the  plane  and  start  the  engine.
The most important items include an electric starter,
12 volt battery, or chicken stick, fuel pump (electric
or hand-crank), fueling lines and fittings and a 1.5
volt  glow  plug  igniter.  Your  flight  instructor  will
probably  let  you  share  his  equipment  for  a  while,
but eventually you'll need your own. Visit your local
hobby dealer or see the Hobbico catalog for a full
selection, descriptions and pricing.
