Great Planes PT-60 Kit - GPMA0119 - Manual (Page 32)

F Use a heat gun to heat and stretch the film around
curved surfaces like the stab and rudder tips, while
pulling on the excess material You may need to pull
hard to get out all of the wrinkles, so wear a glove if you
need to Trim off the excess, then follow-up with your
sealing iron to secure the bond The idea behind this
approach (which can be applied to any part of the
model) is to pre-stretch the covering as it's applied, and
remove the air pockets that can expand later which
cause the sags and wrinkles

Applying windows
Use the patterns on the fuse plan to cut the window shapes
from a black self-adhesive MonoKote Trim Sheet After
cutting the pieces to size, wipe the area to be covered with
soapy water A couple of drops of dish detergent to a cup of
water is sufficient Peel the backing from the MonoKote
Trim Sheet, then 'float' it into position Wrap a paper towel
around a credit card (or something similar), then squeegee
over the area to remove the water Only work in one
direction, blotting moisture after each pass.
D 1 Attach the elevator to the stab with five hinges and
thin CA using the technique described in the Expert Tip
section on page 11, step "D" After the CA has cured, flex
the elevator to check for free movement.
D 2 Install the rudder using four hinges and thin CA.
D 3 Roughen the aileron torque rod "arm" with coarse
sandpaper for better glue adhesion Clean the arm with
rubbing alcohol to remove skin oils or any leftover
petroleum jelly.
D 4 Use a toothpick to pack the torque rod holes in the
ailerons with 30-minute epoxy, then install the ailerons
using four hinges and thin CA Be sure to clean off any
excess epoxy from the hinge line with a paper towel
moistened with rubbing alcohol
................... #2 x 3/8" Sheet Metal Screw (4)
.........Nylon Landing Gear Strap (2)
D 1 Seat the wire landing gear in the groove on the
bottom of the fuse Use a nylon landing gear strap as a
guide to drill 1/16" pilot holes for the screws Secure it with
two nylon straps and four #2 x 3/8" sheet metal screws
D 2 Enlarge the wheel hub axle holes of all three wheels
with a 13/64" (or #9) drill bit and electric drill
...................3/16" wheel collar (4)
(Set screw and wheel collar not included )
D 3 Install the two 3" wheels (not included) on the main
landing gear using four 3/16" wheel collars (not included).
Grind or file a flat spot in the landing gear wire at the point
of set screw contact for each of the outer collars This
provides a better area for the set screw to bite and helps
keep the wheels in place
