World's Fastest R/C Car, anyone?

Maybe scale mph but certainly not real mph. The fastest so far is Cliff Lett's 114 mph run. The fastest out of the box is a claimed 80 mph which is this car http://www.racing-cars.com/usa/produ...?recnumber=292

i guess my remote controlled corvette doesnt count? i seriously wish i had video.

I was reading it. It's not 80 mph "out of the box."

For Top Speed it says:

So well...technically it's not 80 mph right out of the box, but it can reach 80 mph and possibly even more if you play around with the gearing. But Schumacher makes great onroad touring cars.

Wow, I didn't realize that so many of you guys/gals had RC cars. They are truly wonderful machines, that can carry the same technologies as the full-sized scale racing cars.

I subscribe to RC Car Action and RC Nitro. Both are great mags. However, I haven't heard too much about the speed contest latly. Last I knew it was delayed until after June and hadn't heard too much about it after that.

I did have a few ideas for breaking the speed record, but didn't have the resources to make them come true. Of coarse there is always the route of taking and boat load of batteries and hooking them up to a low turn brushless motor. I would say Lithium polymer batteries would best suite this application. But, it would be rather interesting to see a nitro break the record.

Have any of you seen a tether car in action? They are capable of reaching speeds of over 200 mph. That is realtime speed, not scale. In other words just as fast as some of the fastest full size cars on the road these days. the catch is that they need a "push start" to get going, but once they do they rocket up to 200mph in not much time.

Here is a vid of them in action(scroll down almost to the bottem of the page):

If you were to take either a brushless motor or a nitro engine to get a tether car configuration up to speed, that would take place of the human "push start." You would need the primary drive system to get the tether configuration up to about 80mph before it could take off on its own. 80mph is how fast the "push start" gets the tether car going to before it is on its own.

Hopefully the weight of the tether configuration in the car wouldn't weigh it down so much that the primary drivie system couldn't get up to speed(80 mph). It sounds logical, but this would call for a great R & D in aerodynamics and chassis distrabution to accomplish this. Anyone confused?

I have always been interested in this hobby, and because of it I had already had a good resource of info about robotics. I say this to encourage people to look into this hobby. It is not only to have fun, but 3/4 of the time you find yourself working on them, matinenceing them, or learning about them, rather than running them. It definately is a worth-while experience.

This is an interesting article I found in todays local newspaper:

Earning a living is hard, sure, but this is ridiculous

By MARK GUYDISH

WILKES-BARRE - "Yeah," Walter Letanski said on the store phone shortly after the robbery. "Your mother does have a broken wrist and an ankle sprain. They sent her up to get a cast. It's broken in two places."
The snatch-and-run saga that left Karen Letanski sprawled on the ground outside the family store happened with lightening speed, but the effects will last for months.

"Three guys in their 20s came in," explained Walter, owner of Walter's Hardware on Coal Street, on Thursday afternoon. "Two were at the counter talking to my wife. The third guy was over in the hobby department."

Walter was near the back of the store. His wife grew suspicious when one of the men talking to her made eye gestures, apparently to the man behind her.

That man then grabbed a gas-powered, remote-control model truck and ran out the door, with Karen following. The two other men charged out behind her, hitting her in the back and knocking her down. "I heard my wife scream," said Walter, who would not disclose his wife's age.

It was not going to be an easy escape, though.

A customer in the parking lot saw the commotion and followed the three in his vehicle as they ran up a side street, hopped in a car and sped off. The customer continued to follow, Walter said, until the culprits went the wrong way on a one-way street.

One of the three men had been in the store before, about a month ago, Walter said. He came in with another person - not one of those who robbed the store Thursday - and that person tried to buy a model car with a check. But a call to the bank revealed the check was no good, so the men left.

The previous visit, the bouncing check and the parking lot witnesses gave police "a lot of good leads," Walter said, increasing the odds the men will be caught. He praised Wilkes-Barre police for their speedy response.

The toy the men stole? A Horizon Hobby HPI Nitro monster truck worth $400. If it's not recovered, that's money out of Walter's profits. The insurance deductible is more than twice the car's value.

But that's not important, of course. His wife is. He fears she'll be hobbled by the injuries for months.

Which also makes work at the store harder. She's part of the staff, along with his kids. "We really have a family business here," he said, his voice trailing off for a moment.

Then he picked up again. He described the three robbers as white men of average height - 2 or 3 inches shy of 6 feet - and thin.

"It would have been better if it had been my son," at the counter when the thieves struck, Walter said. "They wouldn't have knocked him down."

A customer interrupted, asking for help and guiding Walter to the boxes of gas-powered, remote-control vehicles.

"My son wants one with four-wheel drive," she said.

Obviously, he wants to get his the honest way.

This is when you just let them go. I mean, a swiped Savage will hurt you, but so will a few grand in medical bills.

Let them win the battle--then win the war.

have any of you thought of using dual egines on a car because you could probaly get twice as much speed out of them. You could make a tank that is twice as big so that the car stays balanced. But hooking them both up could be difficult. But the only problem I can see is weight because more weight the slower the car can go. Oh and I was wondering if any one has checked out the traxxas jato if so could you tell me anything about it's performance.

[sanddrag]

There's a couple cars on the market with dual engines, but I think they are all monster trucks. The hardest part is getting them both tuned to run the same. More weight doesn't necessarily mean less speed, it means less acceleration.

[santosh]

Dual Engine that reminds me of the Jep hurrican 2 hemi engines. But back on topic. Who won the competition this year/got the fastest car?

[team222badbrad]

I have not seen the Jato on the track, but I have looked at the truck before it was released at a hobby show. It looks pretty cool, but I am not sure this would be the best vehicle to mod for speed.

How about going for a bigger engine rather than running 2 engines?

The only vehicles I have seen with twin engines are monster trucks such as the Giga Crusher.

http://www2.towerhobbies.com/cgi-bin...&I=LXHJB2&P=ML

My Losi LST has a .26 engine weighs 13 pounds and goes about 39 MPH.

I am sure you could get the 5 pound Jato to go much faster with a bigger engine, the only downside is that you would have to greatly mod the transmission, if not build your own.

Find the most powerful engine with the highest RPM.

The other problem with the Jato is that there is not much room for a bigger engine as far as I can see, I could be wrong here.

The truck seems pretty balanced also, however, the engine is mounted to the left side of the truck.
