Mini cars come
in go in the trendy world of RC. Many times they are too
small, too expensive, or handle poorly compared to their
1/10 or 1/8-scale counterparts. They usually look a little
strange too because their looks get lost in their size
reduction. All this may change with HPI's new Cup Racer
Series of 1/12-scale 4WD touring cars, however. HPI could
be credited with starting a mini trend with their micro
RS4 and its combined small size and scale looks. HPI went
a little bigger with their mini size, then threw in some
real suspension, drivetrain, and normal sized electronics.
That combination alone might have made some people want
them, but throw in some classic, highly detailed bodies
like the Datsun 510, the Toyota Corolla, and the sexy
Datsun 240Z, and more people start paying attention. Can
this little touring car bring back what made TC so popular?
Time will tell, but we took out the 240Z to find out how
this classic body worked on a modern 4WD chassis. |
Features
Stand up, sit, lay down - These commands are usually used
on dogs, or given by our wives, but on the Cup Racer they
refer to the options you have with the front suspension.
Don't be fooled by our lay down position of the shocks;
the kit comes with the parts to allow traditional position
shocks (which work on all the current bodies from HPI),
and when a body that requires a lower front profile comes
along, a simple change of the towers will accommodate it.
We picked the lay down position because it looked cool.
Body of Art - Most touring cars are like a blank canvas.
Take away the headlights stickers and they don't look like
they're of this decade, or like real cars for that matter.
Part of the appeal of TC is that they looked like real
cars. The Cup Racer's body might be heavy, but it's highly
detailed and ready for LED lights!
Mr. Adjustable - The highly tunable suspension is enough
to get you cranked on angles from the start. HPI is all
about details, and this is true of any scale vehicle they
make. The front suspension has degree marks so you don't
have to guess what camber you have on each side. That
compliments the full range of tuning that's on the car and
the array of options parts coming soon.
- Rear ball diff externally adjustable and easy to
maintain
- Front gear diff�highly durable and easy to
adjust the action with grease
- Adjustable wheelbase to fit the wheelbase of the
scale body
- Stand up or lay downsteering servo can be put in
two different positions
- CV-axles keeps the power to the ground; these are
found on high end kits
Testing
It was tough to decide where a proper test should be done.
The body is really too nice to be banged up on an indoor
track, and full-on outdoor tracks are rare and way too big.
So I did what I thought most people would do. I set up a
small course in our parking lot, ran it in the office on
carpet and bombed around in our warehouse on smooth, dusty
concrete.
Acceleration and Speed - What may surprise many about the
car is that despite its small size it uses full-size
electronics and six cells (or 2s LIPO), which makes for
some good old fashion American style fun. Fast! While we
clocked her in at a cool 25mph, that speed was exaggerated
by the smaller size and nimble reactions of the car. There
was some noticeable torque steer, and though it is to be
expected on a small car with a heavy NIMH on one side, it
is still a negative.
Rating: 8 / 10
Braking - I dialed a lot of the brakes out of the ESC,
which was super easy on the Tekin controller. A smooth
finger rewarded me with arrow straight stops on most
surfaces, and a hard jolt of the brakes got the back end
kicking out. This would be desirable if you were going for
a drift, but it can sneak up on you a little. Stiffer
front suspension would help reduce weight transfer.
Rating: 9
Low-Speed - I was pretty surprised by the reaction of the
Cup Racer at low speeds. It was almost a little too
aggressive in that it could easily flick the rear around
with too much throttle, but on the higher traction of the
pavement it was much more controllable. The setup we ran
made for neck breaking left to right transitions and if
controlled properly made for a fun ride.
Rating: 10
High-Speed Handling - Hey, now. I'm sure that when this
was on the design board going 50mph wasn't really a goal.
It's small and it's low and it's fast. Those are things
that can cause a car to have some issues at high speeds on
surfaces that are maybe too rough. I wouldn't say our
parking lot is rough, but all I could think about was if I
flipped or broke a mirror or scraped up the paint on that
work of art I was going to be depressed. So the one time I
was being a hero and ripping a full throttle a small rock
sent it up in the air, but luckily it just jumped and
nothing happened. It was a little too nimble at high
speeds and would probably be more comfortable going slower
on smaller tracks. Dialing that out would hurt some of the
low-end, but that balance of stability and quickness is
often hard to find.

Wrenching
Maintenance - Over the years HPI has made some great leaps
in ease of maintenance, and despite its smaller size much
of the car is accessible for repair or maintenance. If
you've touched a 4wd touring car in the past 10 years this
will feel like an old hat.
Rating: 9
Wear and Tear - Okay, I'll be the first to admit I didn't
try to break this car. I drove it fast but with some care
because I love the body and I wanted to keep it looking
perfect. I did get a little crazy inside and crashed while
drifting, but it wasn't a sold hit. If you flipped this
car over you would probably break a mirror, or maybe a
bumper. These things are replaceable, but many people like
me won't want that to happen and might keep another
bashing body (B-Body) just to have some more fun. Based on
what I put it through it's a tough cookie; just remember
that it's small and little rocks are like big rocks and
can cause some problems.
Rating: 9
Tuning - As I've become an old, wise man in the hobby I've
come to appreciate the appeal of fewer tuning options. The
Cup Racer doesn't lack any tuning options, and it offers
those who want to change things the opportunity to have
some creative fun. It's not pro-factory-racing complicated,
but you can get lost in the options.

Conclusion
Sometimes looks make you ignore a lot of problems, but
this is not the case with the Cup Racer. Put in its
element - small medium speed tracks - the Cup Racer is
going to shine on many levels. Sure, it gets a little hair
raising as the speed increases, but isn't the fun being at
the ragged edge of insanity- The Cup Racer delivers that
insanity at more human speeds, but can provide the racing
platform some may be looking for in a small 4WD. You're
not going to be able to run this everywhere, and just
walking around the body makes me nervous because it's so
detailed, but there's something about an old car that just
makes people smile. This kit provides all the speed,
performance, and smiles a car should.
