Watching a de Havilland Tiger Moth
fly is a special experience—kind of like listening to a string
quartet play Johann Pachelbel’s “Canon” while sailing on a calm
ocean at sunset. I’m talking sheer grace here. With the GWS Tiger
Moth, you can experience this brand of aerial elegance within the
confines of a softball field or even a gymnasium. I’ve been an RC
modeler for 30 years, and weaving this pretty little vintage bipe
around the infield of a local softball field as I stood on the
pitcher’s mound made me feel the excitement of the novice once
again. I call it big-time fun with a tiny RC model.

| As you can see
from the kit contents, the parts count is low, and that means
shorter building time. |
 |
| While there’s
there plenty of space in the radio compartment for the GWS
flight pack—and I highly recommend it—other radio gear will
fit just as well. |
THE KIT AND
CONSTRUCTION
When I hear the word “kit,” images of balsa
and plywood bundles come to mind; I’m talking lots and lots of
parts. As you can see from the photo, the Moth’s parts count amounts
to a mere 35 or so. Low parts count notwithstanding, everything
except the radio and speed controller is right there in the box—even
glue! One of the kit’s nicest features is the well-written,
full-color (that’s right; full color), 18-page instruction
booklet.
Because most of its components are foam, for the
moderately experienced modeler, building the Moth shouldn’t go past
four to five hours. I have only one bit of advice that is not in the
instructions: the struts are made of ABS plastic that has a very
glossy finish. Before you glue the struts to the wings, I suggest
you roughen 1/16 to 1/8 inch of both sides of both ends of the
struts to ensure a better adhesion. If you use epoxy, as we did (a
recommended option in the instruction booklet), this is particularly
important, as epoxy doesn’t adhere well to high-gloss surfaces.

| The GWS flight
pack includes a GWR-4P 4-channel FM receiver, a CS50 speed
control, a 150mAh battery pack and two GWS Pico (standard)
servos. Packs are available for JR, Futaba, Hitec and
Airtronics radios. Price is $95. The crystal must be purchased
separately. |
 |
| Just in front
of the landing-gear wire is the battery-holding box. It is
specially sized for a 7.2V 150mAh Ni-Cd
pack. |
 |
| The tailskid is
simply glued into a precut slot in the fuselage. Vee-bends are
put in both the rudder and elevator pushrods for
shock-absorbing purposes. |
FLIGHT
PERFORMANCE
From the
moment the Tiger Moth left my hand, I could tell it was one solid
flyer. A few slow-flyer and park-flyer designs of just a year or so
ago have given models of this type a reputation—undeserved, for the
most part—of being under-powered, marginal flyers. This is not true
of more recent releases in this market and is definitely not the
case with the Tiger Moth. Though you should never expect anything
approaching glow performance from any model in this class, the Moth
does climb to altitude with authority, and with its gear-driven 9x7
prop, it has enough thrust to get you out of trouble if the need
arises—and, sooner or later, you know it will. Using the 150mAh
6-cell Ni-Cd packs specifically designed for this model, I got 7 to
9 minutes of duration, depending on throttle use. With suitable NiMH
cells, I’m sure 12- to 15-minute flights would be
realized.
This little bipe can be maneuvered in small areas,
doing high, banked tight turns, just as a biplane should, yet it has
the rock-steady characteristics of a trainer and doesn’t show any
tendency at all to snap; in fact, you could teach a beginner with
this one or, with the controls set up at maximum, you can create
your own aerial circus in the confines of a baseball diamond.
This little bipe is so much fun that I could fly it until I
had a serious case of numb thumbs. It’s simply one of the best
flying slow flyers I’ve come across to
date.
CONCLUSION
GWS has really hit upon a
successful combination with its airframes and drive systems, and the
Tiger Moth, in my opinion, is its best yet. It has tremendous
vintage beauty in the air, it flies fantastically and—here’s the
best part I haven’t told you about yet—sells for only $55! What else
can I say but go get one for your backyard or next family camping
trip.
