R/C Car Aims to Hit 200mph
Meet the toy car that's faster than a Ferrari
Radio control car enthusiast Nic Case is planning to obliterate the current R/C land speed record of 134.4mph, with a figure nearer 200mph.
Powered by a 29.6 volt direct drive motor, his home-made X2 R/C car has been months in development and can theoretically hit 274mph. However, the actual figure will be nearer the 200mph mark when you incorporate air and road-generated friction.
Nic has put special foam based tyres on the X2 which can deal with the stupidly high RPM, while a gyroscope will be used to sense if the car goes off course and correct its path.
That’s one R/C car that you don’t want driven into your ankles…

I loved racing Radio Control Cars as a kid, up and down the country... though they would only reach upto 40mph, and you had to manage the batteries against the speed output of the motor or else you wouldn't last the 5 minutes for the race.
I wonder if I can add all my previous R/C cars into my profile:

Once I had an R/C car that hit about 60mph. Unfortunately, the radio signal only lasted for about 150 feet or so until it was out of range. It kind of turned me off to fast R/C cars...
..and the vehicle was last seen proceeding in a northerly direction at a highly illegal speed m'lud...Unfortunately it was "below our radar"Tires will definitely be a problem. They are in tether racing. Tether racing cars race on a 70 foot oval tethered to a central pivot. The "big cars" (10cc -- or 0.60)go over 200 mph. The record is 206 mph. Speeds are somewhat limited because of the cable they have to carry goes up at 200 mph or so.
At 206 mph, the little cars (no more than 6 pounds or so for safety) go so fast that you cannot see them. You can see where they've been by their blue exhaust, and the best tether racers can tell how a car is running by listening to it run, whether the car is bouncing, running to rich or lean, etc.
The cars are timed for six laps. Speeds rise until the engines get too hot and then start to fall off. The racer gets his choice when to start the clock. Cars are stopped by hanging a broom over the track, hitting a lever that sticks out of the top of the car and cuts off fuel when its tipped. The engines have glowplug ignition, so cutting off fuel is the only way to shut them down.
And where I started out, tires have been a major problem, dealing with centrifugal force, the aforementioned bounce, traction, etc, etc. If these electric motor boys think that putting several months into developing their car is going to make them fast, well, look up "hubris" in the dictionary.

There are videos at the site (I could get only one to work) plus oodles of pictures. Check it out.
