Body that aerodynamically possible?

[roosterkill]

80MPH with this new body?? what traxxas has done to the body so it claimed to be capable of running 80MPH? The problem has always been the body lifting the chassis off the ground.

[rustler09]

i think the extra weight in the front MIGHT compensate that problem

[CowboyFan]

I doubt a few ounces will matter at 80mph. Doesnt matter to me, the mamba monster is wild enough in my revo, this little truck will be a hand full with that setup.

[roosterkill]

I doubt that few ounces make any different either.. I hope traxxas had done something to the body so it has good aerodynamics letting good airflow underneath that handsome new body

[Dialed_in]

I was also thinking it would go airborne at high speeds. I just hope the new body doesn't rub like the old one lol.

[rustler09]

a few ounces may not make that much difference, but they most likely added weight to the front (like they did to the rusty for the 70 mph). either way i dont think they would say it, if it couldn't be done. possibly it didn't have a body on it.

[tstmonkey]

Yea, I would think that around 60ish it would blow over like the 2wd version. I sometimes have issues with my 1/16 MERV blowing over at top speed.

[Out of Sight]

Maybe on the real production version..there will be air vents/louvres cut into the body to prevent air build up..but I agree..80mph? I think it will lift up even without the body! It will be good if Traxxas test the new Slash in a wind tunnel and PROVE their statement.

Prove what statement? They never said they made the body aerodynamic for 80mph runs. What they said was the body is more realistic and has sharper edges and bolder curves.

[Out of Sight]

They said it will go 80mph with the MMM brushless upgrade....That's the reason why this thread exists.

And? They probably added weigh to the front. Almost any Rc car including Touring cars have a problem staying on all 4wheels at incredible speeds. We are talking about scales speeds that are close to 800mph.

[Out of Sight]

And...we all want to know how they achieved, and recorded that speed with the MMM..they clearly said "80 mph is in your reach". Well I guess we'll see once its out on the market and prove whether it's theoretically possible or not.

Traxxas has been right about all their speed claims on all there vehicles. It will tell you what they used to achieve that speed. They have nothing to hide or to prove. :)

[StamJato]

I wonder if you could mount these things backwards to help some high pressure air escape? http://www.oocrcracing.com/index.htm

[Nitro Chicken]

LOL! Do any of you remember all the threads stating that 70 was impossible out of our VXL trucks? Please post your doubts here for future reference! :lol:
I am also pretty sure weight was added to get 80.

[StamJato]

Doesn't it make more sense to play with the aero than to add weight? I'm no engineer, but I try to think like one. If the body is modded to prevent blowovers, you could still bash, race, or do speed runs with the same setup, but with weight added to the front of the truck, performance will suffer in other areas.

No one said that they have anything to hide..but indeed they have something to prove again as they've had proven their claims before with their other vehicles.

I didn't start this topic to raise skepticism, rather out of excitement that maybe somehow traxxas had done something with the body so it's capable to handle 80mph speed.

[mistercrash]

Just wait until Over_revO gets his hands on one, he'll make it go over 100 mph. He made the ERevo go over 90.

I was just answering Out Of Sight post. Traxxas just cleaned up the body to make it have a more Corr Truck feel.

The front wheels are pulling plus you have the front diff/drivelines adding weight to the front. 80+ is easily possible.

[Beast Machine]

since this is a post about the 4Slash body. i'd luv to see a pick-up body for the 4Slash.
i'd also add Stampede shocks b'cuz i H8 that sag in the rear.
i dont like the scale realism when it comes to the saggin' rear.
give me good 'ol fashioned high clearance for my driving style.

I was running a 16 oz fishing weight on the front bumper of my vxl slash and at full speen 50+ the body grabbed the wind and took off like a plane. here is the original thread:

I also have a erbe converted to a slash and even with the extra weight of the revos chassis the body still supplies enough lift to send the truck air born.

i don't know if the stock body would do 80, but Sunny, PBO and i have all gone over 85 in a 2wd rustler. all you need to do is drop the ride height, tie the tires or run foams and put about 12 oz over the front bumper in whatever body you run. i used a pede lid. actually, it'll be alot easier to make go over 80 than the rustler. it's going to have much better traction and 100% less wheel spin.

Yup...last year Traxxas CS told me they used almost 2 lb of weight to get their Bandit to get to 70.

The only way I got to 74 is with the weight of the stainless camera on the front of the Rustler.

When running the 8000mah 3s & 35/76 gearing in the Slash VXL I could only get to decent speeds is by using the weight of 2 D size batteries to inside of the front bumper...even with the weight, Sunny only clocked me doing 54 before the front end came up and it became an RC plane. :p

[rustlerbasher]

seriously just put a little piece of lexan on the front and problem solved... that's what we had to do to get my friends rustler to hit 65... then we ran out of parking lot...





(new 4x4 slash) to scale, that's like a corr truck doing 800mph... that's fast :)

[veryfastgt1996]

with every vehicle, it is a combination of weight/ aerdynamics/ power/ battery/ tires/ weather(wind, humidity).

but lowering the body, lowering the truck, adding the right amount of weight in the RIGHT places, 80+ should be easily doable.

also remember the the 2wd slash's motor hangs off the back of the truck, making the truck heavy in the rear. also under acceleration the rear squats and the front rises.

with the 4wd version being 50/50 that issue will no longer be a issue, as will as the motor being being moved forward that issue is addressed as well.

+ the MMM itself will add weight.

i thought that would make a huge difference too. however, i can get my
Losi 8ight to wheelie up on it's rear skid plate with a locked center diff. if the slash has a tight slipper(which acts as a center diff in part), i think it'll still be a wheelie machine. i'm gonna put a wheelie bar on it as soon as i get it as i had to install one on my 8ight.

i think the speed is gonna be quite shocking to alot of people. i was blown away by how much speed was lost in wheelspin with the rustler being 2wd.
i'm really glad they did this.

[toolman]

If you mount this body on your 4x4 Slash, like this guy did on his 2wd, you could hit 80mph.http://monster.traxxas.com/showthread.php?t=453703&page=4
