Great Planes Float Set 40 Preassembled - GPMQ1882 - Manual (Page 10)

❏
1. Install a 5mm wheel collar and set screw on each of
the four ends of the float gear wires. The photo shows the
two right ends of the gear wires.
You must now determine how the floats will be mounted to
your model. In most cases, you will be able to use the
existing landing gear mounting block, already installed in
your model, for the front mount of the float wires. You will
probably need to install a rear mount, however.
If you are installing the floats on a recently produced Great
Planes J-3 ARF (fabric covered), the model may already
have the rear mount installed. Other models will require that
you install a rear mounting block.
❏
2. Place the fuselage of your model on your work bench,
upside down. Place the float gear wires on the fuselage.
Determine if there is a rear mounting block in your model. If
there is, cut the covering from the groove in the block, then
proceed to “Install the Float Gear Wires” on page 11.
❏
3. If there is no rear mounting block, you must install one.
Remove the landing gear from your model. Place the float gear
wires on the model and mark the location of the rear float wire.
Note that we have reinstalled as many of the screws, etc. as we
could, so as not to lose them and to seal the holes in the
bottom of the fuselage. In the steps that follow, we will show
how we installed the mounting block in the Great Planes J-3
ARF. Your model may require some changes.
❏
4. Check for a former inside the fuselage in the location
you have marked. Use a pin to poke through the bottom of
the fuselage and locate the edge of the former. Notice in the
photo how the mounting block will fit against the former. Do
not be concerned if your model does not have a former that
is so conveniently located.
❏
5. Mark the outline of the mounting block on the fuselage
bottom so that the groove in the mounting block will be
directly under the location of the wire already marked on the
fuselage. Cut the covering and balsa sheeting from the
fuselage at the marks. Save the covering.
