    Sometimes you feel like a nut sometimes you don’t. Some say I’m crazy but I have a good time and like Wiley Coyote I’m always scheming how to catch the roadrunner. So here goes.

    It’s my understanding that off all the factors of PWD speed that aero has one of if not the lowest percentiles of cause and affect. But it is a percentile. With the pro division finals between Chuck and Gso decided by .0001 it appears that every percentile matters.

    A 143g piece of wood traveling at approximately 11/12 miles per hour has a very small aero foot print BUT considering Newton’s law of gravitational pull combined with Eisensteins law of relativity the aero footprint should be relative to the object in question.

    Having said that it is IMHO that aero is as important as everything else in the big picture. So keeping in mind that .0001 if the obsession with drill and wheel/axle prep is important shouldn’t aero be as equally important even at 143g @11 mph @ 42’ ?
    Thanks....... RRR

    You’ll notice... if you look at the 3 main leagues and their different classes... the classes that allow fenders... all the pros run fenders. To be honest, my BASX car is the only car I have ever built without fenders, including our Awana cars the last 4 years.
    Since .0001 can often be the difference between podium and not podium, aero is given huge importance. Biggest issue is it adds a lot of work and is a much quicker build without. At the scout level on average (not always) a well built and tuned car doesn’t need fenders to dominate. But in the leagues where a thou or more often even a ten-thou is the difference, you do it all if you want to win.
    Check this video out by John regarding fenders. Can’t ignore results...

    Thanks Mr. Jimmy. I've seen that vid and you and John are correct. I don't think BASX allows fenders which is where I'm at currently. The extra work to create aero is in the Ace's wheelhouse. I've said before we may get outrun but we refuse to get outworked. Got 3 scales coming next Friday to start the weight bias adventure. It all matters when it comes to .0001. Finally settled on the correct avatar....love this one !!

    BASX is definitely tougher when it comes to aerodynamics because you can’t use fenders or air shields. After the chassis is down to 1/4 of an inch and the nose comes to a point, it’s hard to get much more out of it, and it’s also about trying to find the balance between how aerodynamic can I get it, and is it sturdy enough. I’ve had cars break because they are too thin, not necessarily too aerodynamic, but a thin inside.

    Hey Big man Lemme hold a dollar...LOL It ain't the money because my wife has money I haven't spent yet, but no space to put a track. I married way over my head but she is having to tote the load to keep up with my Dr. bills. Getting old ain't for sissies !!

    I agree that fenders are not normally needed at the scout level, unless you run into a league racers son.
    When you look at league racing, we are trying to gather up every .001 we can. Many racers are lost or won by less than a .001.

    Talk about close and a ten thou meaning everything... Pure Stock this month at APR... .0002 separated top 3 finishers.
    2.9392
    2.9393
    2.9394
    Crane’s wisdom being played out right there. Lead changed often. It was a great race to watch.

    I heard that mentioned during the broadcast. At the end of round 1 of Basico the field was separated by 2 hundredths m. That’s a speck of dust in any lane.

    Well, I'm still .0400 off the pace so I would address the 3 main food groups.
    Alignment, Wheels & Prep.

    Thing is, I do what the pros do.
    I just don't do any of it well.
    That's why they're Pros & my cars are just place holders.

    There is easy speed to be had if you use all the technique, tips & tricks we see here, but doing it top notch is the separator & that my friend is where the speed is.
    My hats off to all the top 10 every race.

    Spot on Jup. Those cats don’t get their banners by mail order they scratch for every hundredth a thousands at a time and are willing to share with us what they’ve learned in the past. But I have a feeling they all have their secret sauce they’re not ready to share just yet until the next new thing comes along and I don’t blame them one bit. They shouldn’t have to do all the thinking for us.
