STEP 1:  HINGING THE AILERONS

Important Information About the C/A Style Hinges Included with Your PT-19 Cornell EP ARF

The PT-19 Cornell EP ARF uses C/A style hinges to hinge the control surfaces.  These hinges are designed to be glued into
place, using thin C/A.  Do not glue these hinges into place using any other type of glue, such as thick C/A or epoxy.  Use of any
adhesive other than thin C/A could result in failure of the hinges during flight.

Your kit may include six larger hinges and six smaller hinges.  The six larger hinges are used to hinge the ailerons and
the six smaller hinges are used to hinge the elevator halves and the rudder.

Push two T-Pins through the center of three C/A style aileron

hinges, as shown.

IMPORTANT

  The T-Pins will keep the hinges centered while you

are hinging the aileron.

Working with one aileron for now, slide one hinge into each hinge

slot in the aileron, making sure that you push each hinge in up to the
T-Pins.  Don't glue the hinges into place yet though.

Mix and apply a generous amount of 5 minute epoxy to the gluing surfaces of both the vertical stabilizer and to the vertical

stabilizer mounting slot in the top and back of the fuselage.  Make sure to apply a thin layer of epoxy to the base of the vertical
stabilizer, too.

Push the vertical stabilizer down into place and realign it, double-checking the fit and alignment once more before the epoxy sets

up.  Quickly remove the excess epoxy and use pieces of masking tape to hold the vertical stabilizer in place until the epoxy has
fully cured.
