The bottom of the model is painted. The
fuselage is open on the bottom to provide
easy access to the flight battery.
Acrylic latex enamel, thinned approximately
20% with Windex, was sprayed onto the
aircraft with an airbrush.

I started by painting the bottom color first, followed by the
upper camouflage surfaces. After the camouflage base colors
were on, I went back over the edges to define them, but leave
a soft edge. The canopy and rear fuselage stripe were then
masked off and sprayed.
After a day’s worth of drying, the whole airplane was
rubbed down with 1,000-grit sandpaper to remove any
overspray and leave a smooth surface for applying decals.
Callie Graphics supplied the excellent decals.
With the decals applied, it was time to give the model a few
simple panel lines. These were applied using a 2B pencil and a
plastic straightedge. When they were done, it was back to the
airbrush. I wanted to give the panel lines an accent to further
Using masking tape along the lines and a light finger on the
trigger, a thin layer of paint was spread along the lines—leaving
merely a little color. This was done on every line including the
simulated rib lines on the control surfaces.
I like to use contrasting colors on the lines. On the green
camouflage surfaces, for instance, I use brown to accent. I do
the reverse on the brown camouflage with green. Brown was
also used on the bottom lines. This gives a nice detail that
tends to define the lines well.
With the panel lines complete, it was time for a clear
protective coat. Krylon makes excellent clear coats and I prefer
the satin finish in most cases. The model was given two light
coats to protect the finish. Painting the propeller and spinner
creates an overall good look to the model. With the painting
complete, it was time to recheck the balance and then go
Tony Accurso took the B-339E on its maiden flight. The
build was simple and easy, and flying the model is even
easier. The control throws were set up with dual rates,
using roughly 3/8 inch up and down on both elevator
and ailerons for low rates, and double that for high. I
like to start there and then adjust the
control throws after trimming out
Using approximately 60-70%
power and a little up-elevator
trim, merely a firm straight-ahead
launch is needed and the Buffalo
climbs straight out. After a
decent height is reached, reduce
power to roughly half and trim the
surfaces for hands-off flight.
It doesn’t take long to enjoy this model. The
little Brewster will do any aerobatics that aileron/
elevator-equipped aircraft are capable of and do them
well. Check the stall. If this is done by slowly reducing
power and pulling up-elevator, it will finally drop its
nose straight ahead and start flying again. In a slight
headwind, it will nearly hover in this condition.
Landings are as easy as it gets—either dead-stick and glide in
or use a little power with the nose elevated to pinpoint your
I hope you will try your hand at building and flying this little
Buffalo and enjoy it as much as I have.
