Let's compare a Losi 8ight 3.0 (narrow car) to say an MP9 or D815 car (wide car). On what type of tracks or conditions would the Losi 8ight 3.0 excel or have an advantage over the wider cars that are considered more "stable"? Thanks

Id think high grip the narrow would have the advantage, more agile and quicker weight tranfer, generates less grip so you dont need to use setup to lose grip possibly losing speed at the same time.

Wide chassis has the advantage on loose tracks, as they tend to generate corner grip

in my experience there is no advantage to narrow chassis whatsoever, wide chassis is just more consistent on more surfaces and has superior flex characteristics, this applies in 1/8 and 1/10.

even on super high grip 1/10 carpet racing, the wide chassis cars are better..

Well there has to be something , why else would losi, tekno etc use a narrow chassis if wide was just better.

I would think that narrow chassis would be better in low grip since the mass of vehicle is more closely aligned to the centerline.

what about the goold old mbx7r VS eb48.3 debate ? EDIT : oh I'm in the nitro section !

I can say this. I went from the D815 to the Nb 48.3. Being on the east coast most of our tracks are low grip and bumpy, Medium at best. I am missing driving that D815. The Tekno with the narrow chassis is a handful on these types of tracks. I've had one chance to run it on high grip and the thing was phenomenal! The D815 handled these low traction bumpy tracks much better, not as easily upset, very stable. Also had a chance to drive a Losi 4.0 last weekend. The Losi was hands down a better car on the low traction bumpy track. When their is grip the Tekno really shines, it's an extremely fast and agile car. In my opinion the wider chassis cars are much better in any situation. The Losi chassis isn't that much wider than the Tekno but the extra bit of width it does have made it more stable and bettering handling. The Tekno is very fast, you can see the sections on the track where it shines. I end up loosing time though to the guys driving the Kyoshos etc because I'm fighting the car through the rough sections and the wider chassis car is just floating through it.

Doubtful that any of that has to do with a few mm's of chassis width. Has everything to do with suspension and geometry.

...and 3mm or 4mm chassis.

I have had them all at this point ... Eb48 which is easily the narrowest , to the mp9 which is the widest. In my experience the narrower the car is, and the more centralized the weight is , the more aggressive a car is . It simply reacts more quickly to inputs and the track features. The wider cars are a bit slower to react . I think that makes them easier to drive . Where a bumpy section will throw a tekno into a tank slapper , the K car cruises. The skinny cars also love to take a small mistake and turn it into a big one. Both can be set up to make traction. You have to be a good driver to run the narrow cars consistently, if you can they are very fast. If you don't get to run every week and just show up to run every once in a while , a wider car is the way to go . The wide cars also seem to need less set up work from track to track in my experience.

I guess the wider chassis acts like a lower CG chassis with the parts more spraid onto it

If you guys recall a while back, HB tried to make a car called the CR8 which was an ultra narrow chassis design. I remember a vid where hara was testing it and he said it was too twitchy. Narrow chassis have their niche condtions that it excels in, but like everyone says, wider is more well-rounded.

Alton brought the cr8 concept to AE a couple years ago too hoping to make it happen. That buggy was very slim and the engine was as close to centerline as you could get. I don't think it went over well and we all know what AE did for their 1/8th scale program.
