Smallest RC Cars? 155

fredhsu writes: "My brother-in-law bought two micro RC cars in Japan for me. They are both smaller than a matchbox. DigiQ from Takara is infrared-controlled, has two independent rear wheels powered by two tiny motors, and comes with a pistol-style analog controller. Bit Char-G from Tomy (Tomica) is radio-controlled, single-motor rear wheel drive, front wheel steering, and comes with an awkward controller with forward/backward + left/right switches. You really need to see the video clips to appreciate how small and maneuverable these cars are. I personally like DigiQ more, because of its powerful motors and analog controls. On the other hand, Bit Char-G has an extensive line of hop-ups and accessories. DigiQ sells for $50-$80 and Bit Char-G for $30-$50."

    About five years ago I used to have a Tomy Char-G and played around with it in the office. In the UK there was a limited range, of around 4 colours, each with their own frequency (ie. red controller with red car etc).

    As a result syncronised char-g races occured, with several cars of the same colour being controlled by one handset! Quite fun ;)

    I have a Bit Char-G, and it is pretty cool. It comes in kit form and you build it yourself. To drive it is ok, but better if you leave the chasis off (you can spin a lot better with less weight). You place the car on the side of the controller to charge it up before you use it, so no heavy batteries are on the car. The charged up car lasts about 2-3 mins before needing charging again but it is pretty cool.
    • Yes, and you charge the thing for about 45 seconds to get about two minutes of racing. Just remember to pull out the antenna on the controller all the way and point it in the direction of the car to get the most range which is about 5 metres. 4 of these things make good racing on hard floors in the corridor! Just put a few cones or obstacles and race around them!

      They are not all they are cracked up to be. It's neat to have a tank-like car with treads, but it's extremely slow.

      Also, if I were ever to bring it into the office, I'd be lynched for the amount of noise it generates.
      The USB/Serial interface you can get for it (hooked up via the controller) allows for control from your Mac (OS X only) or PC, but it's not precise. Any macro you try to set for it would fail after a few runs.

      Add to all that, the fact that it uses those mojo-expensive Lithium CR123 batteries (2 of them) and you have a rather unappealing gizmo. I bought two, so I could give one as a Christmas present to my friend, but it's still sitting in a cupboard. I got him a phone, instead.

    Not so long ago my girlfriend imported an Epoch Indoor Racer from Japan. While a little bigger than the cars talked about here, they're a whole lot neater. Real suspension, proportional steering, limited slip differential, and charge up in about 20 seconds. Extremely cool. It's built on a 1/42 scale, making them slightly larger than matchbox cars, but smaller than a CD.

    Also, if you're more the tinkering type, check out Tyco's Canned Heats. I have four of those things lying around in varying states of completeness. They're really easy to modify, so you can make then go faster and whatnot. Pretty fun.
  • I just bought a different brand from a duty-free shop at Tokyo/Narita airport a few months ago. It was a bit larger (about 10cm long) but it had fully digitally proportional steering and throttle with a pistol-style controller, which really comes in handy when you're trying to do tricky maneuvers. It was $45 US and came with 4 spare tires (?!). The transmitter took a 9V battery, and the charging station took 6AA's, so you wouldn't have to get an extra 120V A/C adapter. It's pretty fast, can probably keep up with a jogger. The car's battery lasts about 5 minutes, depending on your lead foot (or finger). My only complaint is that the radio range is only about 10-15 meters :( . But they have at least 4 cars that supposedly run on different frequencies so you can play with friends. I'll try to post a link when I get home tonight.

    I remember reading about R/C cars this size in magazines about 8 years ago, they were $100 - $200 then, and I'd always wanted one.

    The original was by Tomy, being imported as "R/C MicroSizers". The others were Chinese knock-offs (very common in the toy industry...) called "Z-Cars R/C". I think the other was called "Canned Heat, where the cars were packaged in transparent cans. Can't recall the name of the last one.

    All the cars at the toy show only had the FCC clearance for the 45 and 27Mhz frequencies, unlike the Tokyo/Tomy, which offered those plus the 57 and 35MHz. Hard to play 4-man R/C car soccer on only 2 frequencies...

    The price will come down when they hit North American shores in volume, especially with the Chinese knock-offs costing almost 1/2 as much as the Tomy models, although the $40USD/ea I paid for my originals from Hong Kong were well worth it!

    What is more interesting is the fact that Tomy made, in a limited silver-plated edition, given only to top executives (or some other such), an "ultra-tiny" (like, about the diameter of a quarter and a couple of inches tall) programmable "omnibot" (it was of the Omnibot line - just not available to general public). Very, very few of these robots were made. I have only seen one come up for auction on Ebay - it went for several thousand dollars, IIRC.

    Humor, not to be taken seriously

    Imagine this: The Pentagon offers to transport, arm, and fuel home-built drone aircraft to fly against Al Qaeda. Your aircraft must meet the following requirements:
    • On-board GPS
    • On-board video capability
    • Must be controlled via a soon-to-be-built wireless IP network in (let's say Somalia)
    • 500-pound payload
    From the comfort of your home, you can patrol your Pentagon-assigned territory, and engage targets as designated by the JSTARS targeting system.

    I figure the Pentagon can probably turn a profit by charging fees as they provide what is essentially the world's most realistic flight simulator. As an added bonus, they could sell the TV rights to the on-board video. Wouldn't it be fun to watch "The World's Most Terrified Terrorists"? Imagine what the MIT folks could build for this mission!

    I think the most ironic part of the whole idea is that it turns the tables on the bad guys. Under this scenario, their most terrfying time of day would be when school gets out in the US. "Oh no! Schools out! Everyone head for the caves!"

  • I can't believe they would steal cars from Smurfs then sell them to people. They can't get away with this!
  • One of the most thoughtful features (IMHO) in the Bit Char-G is that there is a lever under the car that you can use to "trim" the front wheel alignment. This really helps the car go straight. Also some word of advice on motors. There are four motors for the Bit Char-G. The MicroBee 1.0, 2.2 and 2.6. (I say 4 motors because the 2.2 is available in two part numbers. GS-01 as the stock motor in a kit and S-04 as an addon) The Japanese packaging was somewhat ambiguous as to what the numbers meant. When my friend and I bought one each, we soon learned that it correlates to speed, with 2.6 being the fastest. If you want to race, I obviously recommend the 2.6. I personally have a 2.2, and I frequently find myself spinning out the car. On the other hand, my friend's 1.0 is just the right speed to navigate on smaller desks and ad-hoc obstacle courses. BTW, I landed mine for US$15 whle I was in Japan. ;) Yoshi
  • Think a program could be hacked out so that the DigiQ can be controlled by a Visor or other infrared device? Are there any really small, good quality infrared controllers?


  • Smaller, faster, cooler. It's all great, but the kind of innovation I'd have to see for it to get out of the prototype stage is either better batteries, or more efficient devices that will run for more than 5 minutes.

    Not so much a problem with cars, but with RC helicopters and such, it's not so good when the batteries just die.

    And what about practical applications? RCToys.com sells at least one of their products as something that can actually have industrial applications. But with just 5-6 minutes of uptime, I can't see many practical uses. I'll be impressed if they come up with something that can go for 20-40 minutes without recharging. Maybe fuel cells will solve this.
