Like I said from the start though, this is the wrong car at the wrong time from traxxas; trying to market it as experts only ( by having an insane price... ) is stupid as rich idiots will buy it, thinking they can drive it down the street at 100mph without doing any work what so ever to the setup & radio. Heck, I have dual rates set up on my ~40mph MTs that run offroad when I do straight line runs...

Scale is an odd word in RC. What is a 1/10th scale TC a scale model of exactly? What model car? The basic rule of scale is that it takes 10 1/10th scale cars to equal the length of 1 full size similar type car. But with the different makes and models its a very broad term.
But if you want to fall into that category than a 1/7th scale car like the XO-1 at 100mph is doing a scale speed of 700mph. Its true and not true at the same time. Since at 100mph the aerodynamic forces acting on the car are 100mph forces, and not 700mph forces which is near Supersonic at sea-level.
Look at what happens to this famous clip of a Porsche GT1 flipping at Road Atlanta. I believe the turn is just coming out of the Esses after turn 5. Which means he likely isn't going much more than 140mph but its hard to tell with the camera zoom. But just like the last Traxxas video posted air got underneath the car, not much. But it was enough to act as a wedge and lift the nose more. The more it lifted, the more air pressure there was under the car and the more area the air pressure had to act directly against. Hence the GT1 took flight.
If the air can FLIP a full sized race car why is it so surprising that it can do the same to a 1/7th scale model traveling at 100mph?
