new ParkZone Slo-V
Electric RTF slowflyer is meant for either indoor gym
flying or outdoor park flying. The 45.9" wingspan and
geared 370 power system enable the Slo-V to fly very
slowly at an all-up weight of only 15oz. ParkZone™ Charge-and-Fly™
park flyers come ready to fly. Everything you need to
enjoy a relaxing flight in the park is in a single box,
including the batteries. No gluing, painting, or hassles!
In as little time as it takes to charge a battery pack,
about 30 minutes, you're airborne.

time required to ready the Slo-V is about 30 minutes
it may not actually be "Ready to fly right from the box",
it does come with everything needed to get the Slo-V flying
in one box. This includes the transmitter, transmitter AA
batteries, rechargeable 600mAh NiMH flight pack and DC peak
charger. All that’s left for the modeler is approxametly
30 minutes of assembly, which can easily be done while the
battery pack is charging. Best of all, the Slo-V is X-port
dual high/low rate switch is provided on the transmitter
ready the transmitter, you need only to screw in the antenna
and plug in the 8 supplied AA batteries. Not mentioned
in the Key Features above is that the transmitter has
a switch for high-low rates. This is a nice feature that
I have not seen from ParkZone before. The rate settings
change the control surface gain on the V-tail. The high
rates would be best suited for indoor flying and the low
rates for outdoor flying. The low rate limits the amount
of control surface travel so maneuvers are smooth and
gear mains, tail gear, and wing guides simply press into place
is some amount of assembly required to ready the Slo-V for
flight. The gear mains and tail gear simply press into place
but the wing requires some sticky-back guides and tape to
be applied. My wing arrived damaged but I had no problem pressing
it back into shape before applying the plastic guides that
hold the proper dihedral. Although a bit beat up looking (probably
due to the UPS guy tossing the package into my driveway without
stopping), it should still fly fine.
V-tail is secured to the fuselage using plastic plates and
tail section must be assembled with a plastic "V" piece
and two long thumbscrews. The control rods are then
connected on the bottom side of the tail. I needed to
initially thread my screws in from the opposite side
to get the holes cleared in the plastic "V" piece. The
wing is then secured to the fuselage with 4 rubberbands.
tail linkage connects without tools and the wing connects
with four rubberbands
could not find where the manual said to install the wheels
so I put them on last just before testing the control
surface directions. The wheels simply slip onto the metal
axels and are held on with a plastic cap.
plastic option tray can be used to attach any X-port Module
servos, receiver, and geared motor are all ready to go.
I only needed to snap on the plastic option module tray
for when I test out the X-port enabled Drop Module.
Slo-V was Ready-To-Fly at 15oz
Slo-V was ready to fly in about 30 minutes. The control
surfaces seemed fine and I really liked the High/Low
rate switch function. I can't wait to test fly it
Slo-V is similar in size to the popular GWS Slow Stick
put my new ParkZone Slo-V next to an old "friend" for
comparison; the GWS Slow Stick. The sizes and dimensions
looked very similar, if not exact. The big differences
that I noticed were in the V-tail design and in the level
of integration. The Slo-V comes virtually Ready-To-Fly
in a complete kit and it is X-port enabled. This can be
an easier path for entry level R/Cers and it makes a great
typical take-off with the Slo-V; uneventful, stress-free,
and totally enjoyable!
managed to video my maiden voyage of the Slo-V which is
something I've never done before. It flew great but I
did need to land it and re-adjust the tail linkages since
my transmitter trim tab was at the end and I was flying
with a constant stick offset. All this is captured in
Slo-V cruises around a small field next to the parking lot
where I work.
switched to the low rate setting and it gave a perfect
control for the small field I flew in at lunchtime.
The high rate setting is likely best for indoor flying.
I preferred the low rate setting on the transmitter
since I found myself over correcting on the high rates.
Although the flight time was decent with the stock battery,
the 6-cell pack can easily be replaced with a 2-cell
Lithium pack that weighs around 3oz like the Kokam 1500mAh
cells or the ThunderPower 2100mAh cells.
Overall, the plane flew fine and I had about a 10 minute flight
on my first charge.
The NiMH pack will get stronger after a few more flights.
couldn't tell any difference in flight between the Slo-V
and my other favorite slowflyer plane. Although my preference
is for a standard horizontal and vertical stabilizer,
the Slo-V's v-tail design seems to provide equal authority
and is easier to repair. Spare parts are also available,
The Slo-V lands
without any effort. I simply dropped the power level
and let it decend onto the pavement. I also tried a
hand-toss of the Slo-V over grass and this worked very
well on only 3/4 throttle. Although the Slo-V comes
with an adjustable wing saddle to offset the Center
of Gravity (CG), I saw no reason to change it from the
stock position. For indoor flying, you may want to slide
the wing saddle a bit forward to make the Slo-V more
tail-heavy and slower.
ParkZone Slo-V can be flown either indoors or outdoors. The
45.9" wingspan and geared 370 power system enable the
Slo-V to fly very slowly at an all-up weight of
only 15oz. ParkZone™ Charge-and-Fly™
park flyers come with everything you need in a single
box. In about 30 minutes, you're airborne!
For spare battery packs, aside from getting a second
7.2v 600mAh NiMH Slo-V pack, the 7 cell, 600mAh NiMH
pack used by the ParkZone J-3 Cub is a great choice.
For a longer flight duration, try changing to Lithium
Polymer battery technology. A 2-cell Kokam 1500mAh pack
or 2-cell ThunderPower 2100mAh pack will double and
triple your flight time, respectively.
manual includes some great tips for first-time flyers
and it was well written. ParkZone does not recommend
this 3-channel control system for first-time flyers
but it can be done successfully with the help of an
experienced RC flyer. Spare parts are available for
repairs at your local dealer and it is recommended that
the Slo-V only be flown in light winds up to 5mph.
had a great time flying the Slo-V and it was my first
ever video of a maiden voyage. Although the linkages
needed to be lengthened, no tools were needed in the
field for this alteration. The high/low rate feature
on the transmitter worked very well to limit the amount
of control surface travel. I feel that the overall completeness
of the kit, plane and manual design, and flying characteristics
of the Slo-V was a job well done by ParkZone.
