What's holding speed freaks back? Power or keeping the car down?

I'm still trying to figure out what laws of physics they think they are breaking so I can laugh even harder.

Air resistance, friction, etc.

The "breaking the laws of physics" is obviously a hyperbole though.

Are they running out of RPM on the motor??? Gear it really high, to the point where it can barely move from a stand still....use a push car to get it up to like 50mph, then take over.....

Getting to 200 will reveal alot of new little things that will eventually end up in the AE kits. Looks like they may need to add a wing to that rudder to prevent lift.

At 200mph the governing factor will be aerodynamics.

Overcoming the drag will require a huge amount of power from the motor (gearing up reduces the torque at the wheels so that wont help). The solution will be more volts and more powerful motors!

Downforce will be critical; too much and it will create even more drag (and dig itself into the floor). Too little and it will get airborne.

Awesome project, hope they hit the target!

The car looks remarkably similar to a gentleman who was using a Castle Creation setup to achieve the same goal. Even the bodies orange color is the same.

That is because its the same Nic Case who is the current RC land speed record holder. His last car was Schumacher Mi3-based, this new one is Associated TC4-based, and Associated have obviously chosen to support him.

200mph is definitely attainable power wise. Traction and control will be the problems.

Both.... plus keeping the transmission together, keeping the tires on the wheels, keeping the bearings from melting, etc.

Don't know what technology they used here. But if I were trying it, I'd guess four 10,000KV brushless motors with axle bearings, one on each wheel, direct-drive; solid-rubber tires, and a single ESC that would make your eyes water. Plus a radio that had at least a mile range on the ground (aircraft radios have that range, but only because the model is up high).

Or, to cut to the chase... no electrics at all (except radio), freewheeling wheels... and a small turbine engine like they're using on model jets nowadays.

Those Associated guys are probably encountering problems we never imagined.
