I believe that the engineers have done a good job with this on road car. The use the aerodynamics to help pull the car down to the road. Like a wing only in the opposite direction. The on road car that you had obviously did not have that benefit. They use some similar principles like the Indy cars. If you could invert an Indy car at speed it would hold the road because of this effect. I heard that these cars are a little unstable under 50 mph that is about when the ground effects start to kick in after that it sucks down to the road and is stable as can be. I have a Losi 8ight that will run just like your buggy and it too is stable at around 70 mph, I have not had it to 100mph, but I bet it would be a whole lot different. I'm sure it would not be as stable.

Such a cool car...I am so torn on getting one. I like to drive aggressive and my road that I drive on is probably not smooth enough for the XO. Oh well.

1/8th scale wings are like open wheel F1/Cart/Indy cars. They produce mad amounts of downforce at the expense of high drag from the wing.

A 1/8th scale buggy at 100mph if it still had its original wing will be supremely stable. But it'll require a ton of power to reach 100mph, more than the XO-1 needs due to the massive drag the wing will generate.

Almost all of my old nitro cars that topped out around 55mph would gain another 5-7mph without the rear wing. With the rear wing at those speeds there was massive understeer.

Now fab up a mount and stick a 1/8th wing on the FRONT of your buggy too and it'll stick like glue to the road.

#YOUTUBE TRAXXAS XO-1 they dont go down the street.and as for1/8th scale buggy needing alot of power listen the traxxas XO-1s gearing is 34 tooth mod 1 pinnion gear and 44 or 46 spur or what ever on 25c batteries unless you swap em out now Im geared 33/44 with 65c batteries i honestly get 3 passes then kaput capice.FACT when a rc BUGGY goes 70mph the force is 80 to 90 pounds of pressure on the wing look at it like this a midget stands on our rc wing and a elephant stands on a top fuel dragster.

FACT: that is totally false. For one the wing mount would most likely break with 80 pounds on it. Second of all the bottom of the buggy would be dragging on the ground since there is no way those little shock springs are going to support 80 pounds. Take the wing and mount off of your buggy and hop in the back of a truck and hold that wing up in the air, have your friend drive at 70mph and then tell us if you still think there is 80 pounds of downforce.

Listen dude i work on top fuel dragsters i refuse to argue with you but let me say this,can you name somthing that goes stupid fast that doesent have a wing?The degree/angle always determinates how much force the back wheels apply along with suspention or struts i.e "hookin upp".These brushless cars never hook up you could be at 80 mph and then..tire spin they skate the street the whole way unless you're a beast with throttle control then you wont smoke the tires.by the way what you wanna do wanna line up if the race is right ill fly you down here!

So you changed oil on a dragster once and now you are a pro in aerodynamics? J/K A quick google search came up with anywhere from 3500 to 7500lb downforce on a top fuel car wing. Elephants weigh up to 25,000lbs and average about 16,000lbs. So yes I guess it could be like an elephant sitting on the wing of a dragster...a very small elephant. So now lets scale up the 80 pounds of force on the buggy wing @ 70mph, it comes to 5120lbs at a scale speed of 560mph. Pretty low compared to the dragster. The math shows its plausible. Ill admit I was wrong. And no, im not traveling accross the country to drag race an RC car, however if you want to pay to send me, my doorslammer car and my 2 man crew down there to drag race against your similar street legal car I would be all over that! And no, putting a license plate on the back of a top fuel car does not mean it is street legal!

Here's my set up now lx1e Steve neu built 1521 thunderPower 6s 65c Mamba XL bec disabled added capacitor banks alpha tires rear different spooled. All shocks have no shock oil no downforce in wing and GPS 123mph radar gun124mph the same one you see in my avatar i will say no more my noble knight

Not true Cmac, I love my Losi 8 for that reason, it is completely stable at all speeds. I've had my losi 8 up to 113 MPH so smooth and stable it's not even funny. Just look at my videos. I have one pass at 106mph and it's a cadillac going down the street. So if you guys have any doughts about the stability of a buggy, i just proved it..

That's good to know that it is possible to maintain stability at that speed. I myself have never driven a rc vehicle at those kind of speed. If I can find the right kind of place I might give it a trying. What kind of gearing, motor,esc,tires etc did you use for that kind of speed?
