HANGAR 9 ARESTI 4D
properly positioned for an MDS engine,
but I found that the opening placed the
tank too high relative to the Saito .72's
carburetor, so I enlarged the opening to
lower the tank.
I fitted the fiberglass cowl to the fuse-
lage and used paper templates that I
taped to the fuselage sides as "markers"
for the engine exhaust, needle valve and
glow-plug access ports. 1 then transferred
these marks to the cowl and opened them
up using a rotary cutting tool. I made
under-size cuts and carefully opened
them up to get a perfect-fitting cowl.
RADIO INSTALLATION AND FLIGHT SETUP
Radio installation in the Aresti is easy and
well thought out. I assembled the
pushrods using the supplied parts and
installed the servos, receiver and battery
pack. I hooked up the pushrods to the ser-
vos and control surfaces, and I used the
recommended control throws.
The Saito FA .72 is a smooth, strong-
running engine that provides all the
vertical performance you could want. I
used an APC 12x8 propeller, and it
proved to be a good match; it provided a
nice combination of vertical perfor-
mance and good
top-end speed.
Because the cowl
fits tightly around
the inverted engine
in the Aresti, I
highly recommend
a remote glow
setup. The rear tilt
of the glow plug on
the Saito makes it
cumbersome to
connect a standard
glow igniter. A
remote adapter
solves the problem
beautifully and provides the option to add
glow heat for idle enhancement.
CONCLUSION
The Hangar 9 Aresti 40 ARF is a classy-
looking plane with a no-compromise
aerobatic attitude. It is a great sport plane
and an excellent model to wring out your
aerobatic sequences. It's attractive with its
multicolored trim scheme and has good
contrast between the top and bottom of
the wing. The model goes together
quickly, has a fine-quality fiberglass cowl
and wheel pants and is a terrific value in
terms of looks, performance and excite-
ment at the flying field. ±
