Freewing’s Avanti S is an o;cially licensed
version of SebArt’s turbine-powered Avanti S
designed by Sebastiano Silvestri, a model that’s
fairly well known in RC aerobatic competition.
Constructed out of molded EPO foam, powered
by an 80mm EDF on a 6S LiPo battery, with
electric retracts and a full set of running lights
and beacons, Freewing’s version is an attractive
I found a few demonstration-flight videos
online and thought the model looked just about
perfect for my wants, so I signed up for the
preorder. A plug-and-play model, there’s not a
lot needed to get it flying, just a radio system and
FREEWING MODEL AVANTI S
battery. I have plenty of suitable 6S batteries,
and a quick search through the radio parts box
yielded a Spektrum AR9350 receiver that I knew
would work well, so I was set to go.
When the Avanti S was finally delivered and
unboxed, I was surprised at the low parts count.
;e airframe is beautifully molded, smooth,
well-finished EPO foam. ;e color scheme is
well done, some of it in paint and some in decals,
all fairly well matched and applied. ;e power
system, retractable landing gear, and servos are
all installed, and the flying surfaces are hinged
and ready to connect. ;e battery and radio
compartment access hatch is large, attached to
the fuselage by both strong magnets and a latch
at the rear. It’s covered by the canopy, which is
formed out of tinted clear plastic and covers a
basic cockpit that can be detailed if desired.
;e first thing I did was to avoid having to find
and install a pilot figure by painting the inside of
the canopy black. I don’t like a clear canopy on a
model with no pilot, and the black canopy looks
sharp and fits with the overall color scheme.
While the paint dried, I laid a towel on the workbench to protect the foam finish and started
assembling the airframe.
;e installation of the stabilizer and the fin
assemblies goes quickly. Snake the servo wires
forward into the radio compartment and fit the
parts into place; four bolts hold each of them
securely. It couldn’t be easier. ;e two wing
panels with the retracted landing gear are next.
;ere are three carbon-fiber tubes in the wing:
one glued in the aft part of each wing panel and a
longer one that acts as a spar. With the spar tube
inserted through the fuselage, the wing panels
slide into place easily. A notable design point is
that the retracted landing gear fits easily into
the fuselage through a hole in the wing root big
enough for the wheel. Wing-panel servos, lights,
and landing gear are connected to the radio by
way of a seven-wire ribbon cable—clean and
easy. When it’s all together, four screws hold
the two panels in place. ;at’s a total of only
12 screws to assemble the whole airframe.
;e next step is installing the receiver. All
the servo leads come together in the forward
part of the battery compartment, where they’re
plugged into a control board. Six leads for the
receiver connections are factory installed and
marked, so it’s a simple procedure to plug them
into the proper channels in the receiver. ;e
instruction manual gives basic settings for the
control throws, which have worked well for me.
To finish the assembly, I used the supplied glue
to attach the freshly painted canopy to the hatch
cover and taped it in place overnight.
At the rear of the wing root is a carbon-fiber subspar for additional strength. ;e
molded plastic root is sturdy, and just forward of the main spar tube a connector
circuit board is mounted. ;is makes connecting everything in the wing an easy,
Big wheels, electric retracts with
sturdy aluminum struts, and
trailing-link suspension on all
landing gear make the Avanti S well
suited to grass- and rough-field
;e fuselage wing roots show some attention to detail. ;e wheel well is big
enough to accept the wheel in its retracted position, making assembly easier. Wing
servos and lights are connected by a seven-wire ribbon cable.
;e bottom of the fuselage has a plywood keel molded into the foam for added
ruggedness. ;e large hatch at the left is where the fan unit is installed. Also visible
are the four wing retainers, the red LED, and the two ribbon cables for lights,
retracts, and servos.
