This is a review and flying report covering the ZupAir Zulu 59-inch wingspan molded-foam sailplane
with leading edge drooperons. You might
have three questions. The first one could
be: Will I get my money’s worth when
I buy the kit? The answer is yes. The kit
is an excellent value. The molded foam
prefabrication is high, and the parts
count is low.
Second, is the model easy to build or
assemble? Yes. I don’t see how it could be
quicker or easier. For those who are not
adept at control system installation and
setup, an ARF version with preinstalled
servos and linkages is available.
Finally, how does this sailplane fly? The
Zulu flies wonderfully—especially on
the slope—surpassing my expectations,
even after I’d seen it flown by other RC
pilots. It has the splendid characteristic
of handling gently, smoothly, and
predictably for beginners and less
experienced fliers. Further, in the hands
of experienced slope pilots, kick up the
control surface rates and it rocks and rolls
through impressive aerobatics.
The Zulu is made from EPO foam.
Four large pieces (two wing halves
with carbon-fiber spars embedded, a
fuselage with a motor mount installed,
and the vertical fin) are carefully packed
in separate cushioning bags. There are
also two small foam parts (hatch and
nosecone), and a fiberglass wing joiner.
The elevons, molded in foam, are
mounted and hinged and the control
horns are installed. The required
pushrods and clevises are provided.
Markings were added at the factory.
Included is a concise, nine-page
owner’s manual. No more instructions
are needed because there is so much
prefabrication. Most of the manual
explains the control linkage setup and
variations available for special extreme
and advanced aerobatics.
The recommended radio gear needed
for completion is a transmitter with
elevon-mixing capability and dual rates; a
standard-size receiver with two or more
channels; two mini servos with 2 kg/
cm or more torque (EMAX ES09MD,
