The new Scorpio Super Miss
is an entry-level electric ARF. It's the perfect kit for me to
review at this time, because I'm working on a large scale twin
that I think would be an ideal candidate for electric power.
The Super Miss would be my introduction to electric flight, and
should give me a feel for how all the components work.
The Super Miss kit arrived as you
see it in the picture below. The review package included all
the components listed in Hobby Lobby's "Deluxe Combo"
version, and was quite complete. The very nicely built kit was
in one box. The other items, separately shrink-wrapped, included
a Hitec "Laser" 4-channel FM radio, Sanyo 7-cell 1700
mAh battery pack, a Hitec peak detection charger, JETI 30-3P
speed controller, a separate package of Sermos connectors, solder,
CA, epoxy, an Aero Haut carbon fiber propeller, prop hub adapter,
and an AXI 2814/10 electric motor.

and the motor is a "rotating can" type, so equipment
installation required a bit of creativity. This wasn't difficult,
just different than what the manual showed.

(3mm) were not included. I used Dubro 3mm screws.
Assembly of the Super
The instruction manual for the
Super Miss is simple and complete. The instructions are on the
beginning pages, and the illustrations are in a later part of
the manual, so some flipping back and forth is required. I simply
removed the section with the illustrations, and referred to them
as needed. Since this is an ARF, I won't spend a great deal of
time analyzing each assembly step. There's not much to do!
There are a few nicely-cut ply
parts included for the landing gear, servo tray, and wing joiners.
Everything fit perfectly.
I received the Super Miss accessories
a few days before the kit, so I took advantage of this by assembling
all the electrical components first. Each component includes
it's own instructions, and if you follow them, assembly is fast
and easy. I was able to test the motor, speed controller, and
radio before the kit arrived, and since this was my first electric
kit, this helped put my mind at ease. The AXI 2814/10 motor is
the "rotating can" type, and seemed quite responsive
and powerful. The JETI speed controller includes a BEC.(Battery
Eliminator Curcuit) As with most electric setups, there is a
separate "arming" switch, in addition to the normal
RC switch, and this is an added safety item.
When the kit arrived, I inspected
it carefully. All the covering was very nice, with no wrinkles,
all pre-glued joints appeared strong, and doing a test-fit on
all parts revealed a good fit between the parts. I followed the
instruction manual, which calls for assembling the wings first.
The wings, stabilizer, and vertical fin/rudder are all pre-hinged,
and there were no alignment problems. The dihedral braces required
a little sanding, and then fit perfectly. A nice touch was that
the wing was packed using small grooved balsa blocks to keep
the ailerons from being damaged during shipment.
soldering, and you're done!.
The rear "can" portion of this motor rotates, providing
additional torque, much like a geared motor would normally provide.
It works well, but requires the motor be mounted alittle differently.

were packed nicely, including these balsa blocks to protect the
The aileron control horns installed,
along with some light plywood protectors that prevent any damage
from the (included!) rubber bands used to attach the wings. (top
of the left wing shown) It's a very simple and neat installation.
The prop hub adapter and propeller
was assembled before attaching it to the motor, which is a bonus
of using electric power.
The Aero Haut carbon fiber 10-6 prop is very light! Proper downthrust
is already built into the firewall. Since this in a "rotating
can" motor, the mounting screws go into the front
of the motor. To make this a secure mount, I removed the balsa
front of the fuselage, and added a piece of 1/8th inch lite ply
in it's place. This would not be necessary if you used a different
type of motor.
Since the included
battery pack is the "flat" type, rather than the "stacked"
type, it had to go under the servo tray. The speed controller
and radio battery were simply stacked in front of the servo tray,
and held down with velcro.
The receiver was mounted
just aft of the servo tray, and no additional weight was needed
to achieve the correct balance.
The Hitec "Laser" 4-channel
FM radio worked fine, and I was impressed that even with all
the electrical parts basically stacked together, there were no
glitches or interference of any kind.

|Final steps included running the
motor, to get a feel for run times, painting the cowl section
of the plastic canopy and attaching it, and recharging the batter
pack. The plane balanced at the recommended point without any
additional ballast required.

final assembly, ready to fly.
We arrived at the field
at about 2PM to fly the "Super Miss", under overcast
skies and light winds. The grass was both a little taller than
usual, and a little wet from several days of rain, so hand launching
was in order. After attaching the wing and plugging in the aileron
servo, I advanced the throtte to the 75% position, and with a
light, standing toss, the "Super Miss" was airborne!
The plane had balanced according to the plan, so recovery from
the hand launch to smooth flight was almost instantaneous, and
just a couple of clicks of aileron trim had the plane flying
After getting a feel for the throttle response
and control inputs, I flew some gentle turns, and low passes
for the camera. Next, I took it to a little higher alititude
and tried some rolls. Rudder helps accelerate the gentle roll
rate, and the plane rolls like a typical trainer. Loops were
reasonble size, and no problem. Back at altitude, I slowed the
plane down, and gradually added elevator, until it gently stalled.
Recovery was very fast, requiring only a bit of throttle, or
a gentle lowering of the nose. Finally, I did some spins, which
were the gentle "trainer spiral" type, and even a
couple of snap rolls. Although not an aerobatic design, the plane
performs all these maneuvers with ease.
Landing, either with power or without, was simply
a matter of letting the plane settle into the approach naturally,
and gradually increasing elevator input to flare when a foot
or so off the ground. You can tell from my goofy grin in the
image below, that we had fun with this little plane, and I'd
recommend it to anyone as a second airplane, or as an introductory
Super Miss ready to fly!
The Super Miss is an
entry level electric kit that can be considered a good intro
to ailerons, a good intro to electric flight, and in general,
a good "second airplane" for new RCers. With a little
throttle management, flight times around 6 to 7 minutes are normal,
and the battery pack can be recharged with the Hitec Peak Detection
charger in a little less than 30 minutes. These times will be
shorter or longer depending on your charger.
Here are some flight photos. (Click for larger images)
This kit was my introduction to
electric kit construction, and was a good one. Following the
included instructions included with each component resulted in
all everything functioning correctly. The Super Miss was easy
to launch and had plenty of power. It was faster than I expected,
but still lands at a moderate speed, with no tendency to tip
stall. This is probably a result of the elliptical wing planform
and dihedral. This, combined with the flat bottom wing, gives
gentle flying qualities overall. I did roll, loop, and spin the
plane, and it handles as expected. Roll rates are fairly slow,
as expected, but adding a bit of rudder helps a lot. Overall,
the plane flew quite well, and I'd recommend it as a good second
plane for anyone. The slow roll rates are good for those new
