Bushing Alignment 101
We've had quite a few questions about the setup for our world record breaking 24-hour car. Many of the questions are along the lines of "What's the one thing that made the biggest difference?". An obvious question but not one that is easily answered. Our response generally goes something like: "The one biggest thing is paying attention to a LOT of little things." This may sound like a bit of a smart-ass answer; however, it is very true. Ask any experienced car builder who races competitively and they'll probably agree. The old saying, "The devil is in the details." certainly applies to setting up a slot car.
One example of a little thing is bushing alignment. Many racers never give the rear bushings much thought - snap them in place, maybe a little dab of glue, slide in the axle and secure the various drivetrain components and away you go. Unless the bushings are badly misaligned, the axle (and wheels/tires) will spin; however, it's important to keep in mind that ANY unnecessary friction in the drivetrain WILL adversely affect the cars performance - acceleration, braking and top speed. While aligning bushings may seem like overkill (and it may be for some racers and some types of racing - we're not suggesting every racer has to do this for every car...), it's a great example of one "little thing" that when combined with a bunch of other "little things" can make a big difference.
Aligning bushings is not difficult - the how-to videos we put together describing the process take longer to view than it actually takes to align a set of bushings once you've done it 2 or 3 times. Take a peek and you can be the judge if bushing alignment is something you want to include in a future build.
