set of recommended control throws and
exponential rates, including flap throws.
The recommended CG is provided in
the assembly manual. Placing the flight
battery squarely in the middle of the
space provided for it made my Strega
The Strega’s all-up weight is 48
ounces. Using my Eagle Tree eLogger, I
ran the Strega up on a freshly charged
flight battery. Holding it at wide-open
throttle for a 15-second burst yielded a
static reading of 600-625 watts.
RocHobby does not provide
information or specifications regarding
the Strega’s wing area. I calculated it to
be roughly 308 square inches. Armed
with this data, I calculate the Strega’s
performance to be an impressive 200
watts per pound, with a wing loading of
22. 4 ounces per square foot.
But enough of this number mumbo
jumbo … let’s get this racer in the air!
I was slightly reluctant to break down
the Strega for transport because of the
way that I had arranged the abundance
of servo wires within the square cavity
located above the wing. Fortunately, the
model fit fully assembled into the cargo
compartment of my midsize wagon.
Model aircraft in this 1-meter-
wingspan range strike a nice balance.
They are large enough for good in-flight
visibility, yet small enough so to not have
excessive demands when it comes to
storage and transport.
Pull the wing if you must. The four
fasteners are perfectly aligned and
reattaching the wing is stress free. Ensure
that you get all of the connections
correct when reattaching the wing.
It would be nice to see RocHobby
utilize a combination-style connector
to combine all of the functions of each
wing half into one connector, such
as is used on some of the larger FMS
warbirds. This all but eliminates the
chance for making a servo connection
mistake when repeatedly removing and
installing the wing.
At the field, I always perform a quick
range check and final verification of
control surfaces. With my daughter
poised to gather in-flight media, I
I upped the throws on the rudder in
my transmitter to 125%, which slightly
decreased the turning radius. Any
additional improvements will have to
be undertaken mechanically by shifting
the pushrod(s) around on the servo and
control horns. The rudder and tail wheel
are attached to the same side of the
rudder servo horn.
Dropping the flaps to half position,
I positioned the P- 51 at the end of
the runway and slowly eased the
throttle forward. The Strega smoothly
accelerated, pivoting up onto the mains
as it built speed. A little preemptive
right rudder was required to keep it
With a subtle pull on the elevator
stick, it was off and climbing. I initially
found it necessary to keep pushing
the nose down as it climbed out, but I
held off applying any trim until after I
had pulled up the flaps and gear. With
the flaps and gear stowed, six clicks of
down-elevator had the Strega holding
altitude with minimal stick input.
My first few flights usually involve
plenty of slow-speed flying to give the
photographer good photo opportunities.
Exploring this flight profile early comes
with the added benefit of familiarizing a
pilot with how the aircraft will behave at
slower speeds and when in the landing
pattern. The Strega was impressively
stable and docile while cruising at
approximately half throttle. But slow-speed flight is not what this model is
Upwind and at altitude, I firewalled
the throttle stick and set up the Strega
for a diving, high-speed pass down the
runway centerline. Leaving the throttle
at full, I carved several tight, oval
patterns around the field to simulate a
Reno-style Pylon race.
The sound of the four-blade propeller
and power system at maximum output
is pleasing to the ears! The Strega stays
nicely on track and is arguably one of
