1740g's too. Still experimenting with amount of ballast and location tho. Its working really well tho to be fair.Under servo, under speedo and about 40g under lipo. I'm using thin lead sheet so its easy to cut and fit.

What's the thinking behind running that amount of weight?

Sounds surprisingly heavy!

lipo and brushless more than makes up for the extra weight

Well there's a little bit more to it than that. First of all there is front/rear distribution and then there's overall weight.

Distribution if you weight your car up front to rear you want something around 35% front and 65% rear. This is more important than overall weight.

If you run a big lipo then chances are by the time you've added wieght to the front you'll be in that overall weight ball park, however this is not a bad thing as often weight is grip and it almost always makes the car easier to drive.

So you're saying you need to weigh the car to 1740g to get the correct front to rear weight distribution?

Weight does not only apply to the X-6, it's all cars. A light 2wd car doesn't have much grip and with the amount of power we have nowadays you need a bit of weight to keep the wheels on the ground.

What dan is saying is that don't just add weight and expect the car to be perfectly balanced.

The optimum weight/grip ratio seems to be around 1740g, this is something that the X team have speant a lot of time figuring out. Once you have figured out how much weight you want to add you then need to think about where you want to position the weight to affect the balance of the car. Again the X team have also worked hard on figuring the best front to rear ratio for the X-6 and Super_Dan has worked hardest to figure out that the dream figure is 35% front 65% rear.

Concerning the fairly high weight for a 2WD buggy:
Do the guys in the States add a similar weight in the car, for instance at Cactus Classic?

The AE team uses a so called 'lightweight setup' for LIPO with a weight of the B4 of 1515g ready to race.

/norbert

P.S.: I received my Squared just right now and couldn't give it a go up to now...

If you weigh your car up to 1740g then you want the weight on the front wheels to be 609g and the weight on the rear wheels 1131g

Interesting reading all this!
I've been running a light X6 with a Tekin 3400mah lipo which only weighs 204g!!

Just put some full strip lead sheet under the lipo and under the ESC to take it up to 1700g

Well I don't run an x6 and to get to 1740g I would have to run 420g of ballast which simply wouldn't fit without a redesign of the chassis (unless anybody has a load of spare tungsten they don't need.)

I currently have a 65 / 35 weight distribution at the minimum weight limit.

It sort of seems counter intuative to be running that much ballast on a racing car.

Dan / Body Paint. Out of interest what sort of tracks were you testing on to come up with that weight?

Were they particularly bumpy?

The reason I ask is that yes heavy cars generate more grip but they also generate more momentum and higher lateral loads too. - So I can see weight being an advantage on rough tracks., but on a smooth track I would expect cornering speed to be worse than for a light car.

This is certainly what you see in touring cars and 1/12.

the 1740g is x6 specific not 1/10th offroad specific we have jus found that this weight works best for the x6 with lipo not sure about other off road chassis sorry
