I don't understand the quest for the lightest buggy when it doesn't seem to have any relavance to what wins the race

the smoothest thing over bumpy ground is a 70 ton mbtank

it matters because the less weight, means less likely to break. My 3922 gram mbx5r was breaking arms like crazy. It even got called a fat car by the JBRL guy at round 5.

Round 6, with an 808 that weights 3326, i qualified basically the same with only 1 round, as i did in 2 rounds with the previous car.

Weight does matter, especially when changing the direction of the weight once moving. Coming out of a corner and going around corner the lighter car will always win, assuming balance and tires are similar. Coming out of a corner and hitting a jump should be double the benefit with a lighter car. If spring ratios and oils are set up properly, a lighter car can perform as well as a heavy car in the bumps also. Your motor works less, your clutches last longer, and the car wont beat itself up so bad in crashes if its lighter.

Just some thoughts...

MMM, power to weight ratio, isn't that what we strive for
Quicker in all aspects on the track, even on rough areas,less momentum.

I get the principal but how often does it transfer into an actual result ,with half a dozen manufacturers having cars in the worlds finals all of different weights and possibly but I don't know for sure but one of the heavier cars won ......it seems to be more about bragging rights than actual fact

another thing ,if a car is heavier the window of oil wt and spring strength is wider and would in theory at least be easier to tune and would also be less critical to track condition.

Lighter should also give you better runtime. The only thing I dont like about lighter is that the heavier buggies can push you around.

so... if the weight transfer and the side to side balance is what makes a good buggy then I guess that Hot Bodies really has a top performer with the D8 after placing four buggies in the final event and winning the championship...

Once you start adding different servos it makes one hell of a difference. Some are double the weight of others.

We need a comparison of rolling chassis without wheels and tyres.

I'll tell everyone at the track to dismantle their buggies next time I'm weighing them Seriously, thats up to the manufacturers to start advertising naked weights. Or at least somebody that has access to all the naked kits. Weights will start to be advertised as they are becoming a selling point, just like in other industries

The biggest portion of the D8's weight is the chassis. The thing is almost a pound by itself.

they went with a 4mm chassis witch is great to prevent too much flex but, it adds weight to the overall picture... still handles great

I think the best way to evaluate a product, is to look at the mythology behind the product.
Most of the buggies out there are pretty much the same and I'm sure that all of those A-main drivers would have been more or less placed the same if their buggies were different.
One thing is for sure, a lighter buggy will be faster around the track in any reasonable drivers hands!!!
Tyre weight is the most important factor and this is something very few drivers think about
Think about it this way, if a buggy weighs 3500g, it is a 300ml soda heavier than a buggy weighing 3200g ,now think if you have to catch that soda traveling at 30 mph, damm it'll hurt

Dang.... and that Losi even has a tank of a motor RB C6 on it. WOW nearly 1/3LBS. When I drove the D8 I knew it felt heavy compared to my 808, but I didn't think it was that heavy.
