Before beginning construction, be sure to acquire the materials and tools necessary to complete your
model. You will need glue suitable for bonding wood, such as cyanoacrylate (super glue, or CA), white
glue, wood glue, or Duco cement. Protect your work surface using a sheet of parchment paper or wax
paper. For cutting the wood parts apart, a SHARP single edge or double edge razorblade is needed. A
sanding block and CA accelerator (if using CA glue) will be helpful.
It is not necessary to sand the parts of the One Sheet Glider in order to obtain a flyable model airplane,
however your model will fly much better if you take the time to properly sand the flying surfaces. Proper
sanding results in higher launches and improved glide performance. In addition, a well sanded model is
easier to adjust for proper flight.
Humidity is the enemy of a consistent flying glider. Changes in the moisture in the atmosphere causes
the water content of the balsa wood to change, resulting in warped flying surfaces which can make your
model unflyable. One method to protect against these warps without adding so much weight as to make
the model fly poorly is to lightly varnish the entire model with a spar varnish. The brand that has given
us the b
est results is Minwax Helman’s Spar Varnish. It can be wiped onto the model with a paper towel,
and any excess quickly wiped away. The goal is not to get a glossy finish, but rather to get a light coating
to soak into all surfaces of the glider. The varnish will take about 12 hours to dry, after which the entire
model should be very lightly sanded with 300-600 grit sandpaper.
Many fliers want a beautiful coat of paint on their gliders so they look eye catching. Warning: a thorough
coat of paint will make your One Sheet Glider too heavy to fly! If you are concerned about seeing your
model in the grass after it has flown, a very light coat of paint may help. If you seal your model with
varnish as described above, you can add a very thin coat of spray paint after sanding the model. Hold
the spray can 10-15 inches from your model and give light passes of paint with a sweeping motion. Only
add enough paint to your model to get a hint of color. The wood grain should still be clearly visible
through the paint. If you paint the model in this manner, you will add only a fraction of a gram of
weight, so your model’s flight performance will not be degraded. Any more paint than this can render
the model completely unflyable, so avoid using excess amounts of paint.
