i figured that they did being it was the first outing with the car at a big race. and from the extremely good results,it looks like it is working very well.congrats on the virgin run with the new car. [/QUOTE]


You never implied anything other than that...it was another poster that made the comment...

It's all good....I'm sure that there were several BMI chassis cars that did well too(for many different brands!)

I ran a BMI T2 carpet chassis set at Vegas mod and 19T foam tires. I thought it worked good. Then I started having a little problem of the car not feeling like it was in the track. As it turned out, the grip for a big carpet race was not there as usual and tire wear was high. I asked some team drivers for some advice as this was the first time I have ever ran foams. They said the BMI chassis was too stiff. Everyone that was running one that switched back to a stock chassis went faster. So I did that and that didn't help at all. What I did in my last race was to sauce my tires longer and that was it. I guess maybe I asked the wrong questions and didn't really know that it was lower traction carpet then normal. I was told that as the event went on longer to sauce less and less time on the tires. That's what I was doing. I sure did learn a lot.

that is pretty funny that they told you that.it doesnt surprise me though. Andy Moore changed over to my cyclone chassis kit which was alot more rigid than the chassis he had and he said it was night and day better than the chassis he went there with.sorry to hear about that though buddy.that was new conditions to most i spoke to.and to see alot of drivers changing to double pink fronts was pretty wierd too.

AS FOR JAYSONS CHASSIS'S THEY ARE THE BEST IN THE BUSINESS I REALY THINK THEY COPIED OFF OF HIS DESIGN.MY BMI T2 IS ALWAYS EXTREMLY FAST SO YOU WONT SEE ME WITH A 007.ALSO X RAY WAS SO INVOLVED IN THE FLEX CHASSIS AND DIDNT KNOW THAT A STIFFER PLATFORM WILL OUT PERFORM A SOFT FLEX CHASSIS.WHEN YOU SET THE GEOMETRY OF THE CHASSIS A STIFFER PLATFORM WILL BE MORE NOTICEBLE TO SLIGHT CHANGES WITH A WEAK CHASSIS SET UP CHANGES WILL HAVE TO BE MORE DRASTIC TO GET THE SAME FEEL.

Sorry I have to disagree. I don't work at Xray but I know that they have engineers and designers who do this stuff 8 hours a day 40 hours a week and so on. If they are pursuing a design idea and it makes it into production then rest assured that it's going to impact performance in a positive way. I believe currently they know more about chassis flex then anybody out there. It will be interseting to see how far they develope it.

hudy/xray does do nice stuff but i definately think that tamiya is top as far as developement and inovation.just look at how they always set the new platforms and standards.

That they do, no doubt, but I think Xray has got some momentum going and have Tamiya looking over their shoulder.
Great stuff....

Not true they seemed to eliminate there flex settings if you look at the new breed.I know a lot about suspension geometry and chassis stiffness been around full scale racing longer than rc companies so believe it or not but i know what i am talking about.

Look again. The US version has the flex slots removed to make it stiffer for carpet but the EU version is for asphalt and has all the flex slots as the T2 plus a few more flex options.

In basic theory you are completely right in saying that a stiffer chassis is better. However that only holds true if you can generate enough overall grip to ensure the tyres and suspension setup can handle the maximum side load put on them during cornering.

Unfortunately in rubber tyre racing the simple fact of life currently is that we don't generate enough grip given the very high speeds we run at nowadays. This means we need more options than just the suspension (damping) to absorb some of the peak load during cornering. This is where chassis flex comes in.

Comparing RC to full scale racing is generally ok, but not allways completely valid. For one thing I have yet to see a full scale racing car go through corners at a speed of 500Kph on a road coarse or do 850Kph (with brushless it would be over 1000Kph, i.e close to the sound barrier!) on the main straights. Scale wise these are the kinds of challenges RC car designers have to cope with today.
