A shrunken speedster revs up

The latest run of Nic Case's car topped his previous record by nearly 30 mph
John Gilhooley
After a motorcycle crash, Nic Case found a safer, but still thrilling, hobby: building radio-controlled cars. At 161 mph, his latest just smashed the world record.
The 46-year-old eked out extra mph any way he could, including adding an 11-horsepower R/C motor and a 12-cell battery pack normally used in hobby airplanes. He made sure his handcrafted carbon-fiber chassis would generate enough aerodynamic downforce to keep the vehicle on the track, and he designed an all-wheel-drive system to further increase traction. He also used a high-frequency receiver to ensure that he never loses control of the car.

So far, Case has raced it only twice, and he thinks he has a good shot at his ultimate goal: 200 mph. "The car's got more," he says. "I left a lot on the table."

Time: 6 months
Cost: $4,000
Handling: The car has no brakes, so Case dials back the power to the motors to decelerate. To prevent flipping, he added a gyroscope-based steering-correction system normally used in remote-control helicopters.
Tires: Case designed oversized tires to improve the airflow beneath the vehicle. Instead of relying on glue, he had the rubber vulcanized to the aluminum rims, "It's one less thing to fail," he says.

I would like to know what is the fastest electric car without all the money and gadgets added. I'm talking about an RC car using the hop ups maybe and making ones own tweaks to add to the performance. Anyone can take $5000 and make a RC fly. Not to say I'm not impressed with the 167 record it would be nice to know who holds the record of an out of box RC. I have a rustler that does 10 over the 70 mph from tweaking the chassis and gearing but if I put $5000 into a $300.00 car I'm sure I could add some speed to it.
Very impressive. It would be cooler if he added a small radio camera so you could see what it looks like moving that fast at only 1 inch off the ground.

if he added a radio camera it could knock it off balance and slow it down plus it could wipe out the battery
that is cool, i might try to make it.

very very very cool 161 mph! thats just crazy fast thats faster than a lot of cars thats cool how the world is making stuff never thought possiblea couple of years ago go america yah
That is indeed pretty cool.What is the world record for a "nitro" (glow fuel) powered R.C. car? Maybe I could take three or four jet engines,put them in a full size streamliner,hook radio controls to IT and put the record so far out of reach no one would ever break it.Surely that wouldn't be considered cheating,would it?
out of the box RC cars are not designed to go that fast , the point is he had to solve all the problems associated with going that fast with a minature RC car . Its sweet
great point, steve, and right on the mark.this is probably worked up on nothing more sophisticated than my Unix based pc, and the data is just as relevant as the bigs. wonder if he has tried to interest anyone in his data, like Team N.A.E. is doing. great work, Nic, and great point, steve28.
That looks like a nasty car! I'd love to get my hands on the RC of that one...

As far as expense you don't just double or triple cost to double or triple speed, even with real cars. 120 mph is very easy to attain with today's automobiles, but to go 240 you need a lot of money to get serious hp and you need good aerodynamics to be safe. To go 360 it gets crazy. Cost is not linear but an increasingly sharp curve upward as you increase in speed (assuming the same factor of safety and reliability). Hotrods big and small are expensive projects, especially when you go big.
Im using this article as a report and I was wondering what the range on these cars are. Thanks :)
Although a very cool gadget, the price tag of 4,000.00 is not in realms of the average remote control car that "Dad" and the kids play with on Sundays. This is a serious remote control and not what I would term "gadget". I would be interested to know how much range this little gem gets per hour; how long the tires last and what is the overall life span and replacement costs for parts, including the battery?

Wow this is amazing and to think the humble remote controlled car now travels at a speed equal to the road cars. I am assuming, as I don't know much about the quality and cost, that this is top range and for the serious user.
