ABOUT ADJUSTMENTS
R/C race cars, in general, are some of the most adjustable racing machines of any
scale. What’s really amazing is just how easy and quick it is to make all of our changes:
remove a ball stud to change roll center, one screw to change springs, or tape in some
weight to change the car’s distribution. On top of that, the X – 6 Squared is even more
adjustable, adding options like the transmission height and the servo position that many
other cars don’t have. It’s easy to get lost though, so here’s some advice from one of
the best in R/C racing, Brian Kinwald: “At any given track, only a few adjustments will
help the car get around the track faster. 90% of set-up changes just alter how the car
feels. The trick is to find those changes that really make a difference, and use the rest
of them to get the car to suit your driving style.” If you ever feel lost, like the car isn’t
working at all and you can’t seem to get it back on track, change completely back to a
standard set-up or something that worked previously and start again – it’s how we learn!
When there are lap times available, pay attention to both your fastest lap and you
consistency (how close the other fast laps are to the fastest one). If your fast lap is
significantly quicker than average, work on making the car easier to drive; if you can run
close to that fast lap the whole race, add some more steering or power and see if you
can go faster.
Finally, don’t be afraid to acknowledge if a set-up change didn’t seem to affect the car
on the track. Some adjustments are subtle, and different driving styles are sensitive to
various adjustments. Learning that an adjustment didn’t change much for you is a
valuable result – focus on other things, and perhaps try it again later as your driving
experience accumulates and set-up evolves.
DRIVING THE X – 6 SQUARED
The mid-motor X – 6 Squared is obviously a lot different than a rear-motor buggy, and it
can take a bit of driving to get used to. With its weight more central the X – 6 Squared
naturally caries more corner speed. With no “pendulum effect” from the motor hanging
off the rear axle, the car likes taking smoother racing lines, while the rear end stays
more planted. Watch out that you don’t slam into the motor guards of other buggies
through the infield!
