  • They're neat little toys, I've seen a couple reviews of them in the past. They seem to get a pretty decent amount of battery life (compared to the average 12v RC car), some even have little charging stations on the controllers themselves.

    I still think I prefer the larger version RC cars though.. I'd like to see one come out with a mini fuel cell, that'd be slick.
    • No such thing as an average 12v RC car. The *average* electric RC car runs on a 7.2v, 6 cell battery pack.

      Even the cheap RC cars found at retail outlets are usually 4.8, 6.0 or 9vdc.

    At least they decided to use 4 different frequencies. With 2 brothers, I can't tell you how many times we fought about who got to use their car at that time. It made for frustrating races when an annoyed benchwarmer would turn on his controller and flick the controls.

      The article says "Here in the US only two frequencies, 27MHz and 49 MHz are licensed for wireless toys, and are used. That means only two cars can race each other at once, because otherwise the signals will conflict. You can find Asian imports in some places that operate at the other three frequencies, but they are not FCC-approved for the US."

      Sadly it is a real pain not being able to race more than 2 at times.

I played with one of these slick racers, but didn't opt to buy one myself because of the lame fun of only being able to race one other person. Now, how hard would it have been to use one channel coded for multiple devices (say 16 cars)? Damn, could you imagine the fun of setting up a track with 16 cars!

        Unless you have a Ham license -- there are frequencies allocated in the 6m (50-54MHz) amateur band for remote control. You must have at least a technician class license and follow some rules about having your callsign on the transmitter. You'd have to retune the transmitter and receiver but that is most likely just a new crystal since there isn't much of a front end on those things anyway and 47MHz is pretty close to 50MHz as far as the basic circuit design is considered.
      • Uh, the article is goddamned ignorant. I've personally participated in races involving four 1:10 scale cars. You don't need an entire MHz of bandwidth to control a radio control car. It's actually enough to have something like one-thousandth of that.

        One assumes that the bands are somewhat closer together for surface vehicles, because typically they only require two channels. Ritzy ones (like those with selectable forward/reverse) have three channels. Planes, on the other hand, often require four channels, and some radio control vehicles use as many as eight. Helicopters use five or six.

        this chart [greathobbies.com] describes the frequencies available in Canada, not the US. But note how close together the various frequencies are.

        Frequencies-As mentioned earlier, there are different frequencies used for controlling aircraft and surface models. Government has allotted one aircraft frequency band (72 MHz) and one surface vehicle band (75 MHz) for use in controlling models. The separation is for public safety. Each band has quite a number of individual frequencies. In addition, some equipment may be available on ( 27 MHz ) which is the CB band or on 50 & 53 MHz which is for Amateur Radio operators and a Radio Amateur's operating license is required to use equipment on these frequencies. These Amateur Radio frequencies may only be available on some equipment and would always be on a special order basis only. Delivery is usually in the order of 6 to 8 weeks.

        (Introduction to the Radio's Controls [gbso.net]. Radio Control Center, 1997.)

        So this is just plain lameness. I've personally witnessed more than 20 cars in operation at one time at the races sponsored by my former local hobby shop.

    I haven't seen either of the cars in the review, but when I lived in Japan lots of people had one called "Char-G" and it they were rediculous little things. Hobby stores had whole floors full of customizations for these things: faster motors, custom frame parts, etc... When it came right down to it though they're just not that fun to play with. They don't have the all terrain capabilities of regular-sized RC cars. When I played with my friend's Char-G it was only fun for about 15 minutes....and all I did was make it zoom around in a figure 8 for a bit and run it down a few flights of stairs "to test its durability" then it had to be recharged and after that I didn't really feel like playing with it anymore.

      • I picked a very similar R/C car up at a Discovery Channel store months back (looks like the same chasis, different brand name). My 150lb Newfoundland dog is TERRIFIED of it! Kinda like a mouse and an elephant. Pretty funny.

    • If you want a moderately small but still entertaining RC car, consider HPI's Micro RS4. They're considerably more expensive but they're very fast. They do not however have a lot of ground clearance. They are built like a (somewhat smaller) 1:10 scale car, and they move like one, too. They are AWD which helps traction on varying surfaces. Like other very small cars they are not suitable for anything deeper than office carpet (IE, the stuff that survives chairs being rolled all over it.) You can also race them outside on fresh tarmac or concrete.

      Actually they have almost as much ground clearance as 1:10 scale saloon racers. I broke the shit out of my 1:10 scale impreza (A Schumacher SST2000) by hitting a ~0.5" crack in a concrete street at about 28mph... and that's an electric car. Some of the nitroethylene-powered cars will do 50 mph out of the box. Well, once you break in the engine anyway.

      Personally I'm waiting for a R/C truck or buggy about the size of a Stomper (remember those? Ran on 1 AA battery? you could build tracks for them in the sandbox?) with working suspension rather than the stomper's fixed axles. I'd even settle for independent front and a fixed rear, if I had to.

      We discoverd that if you put the platic guard rails around the outside of every turn, you could even run them on slot car tracks. Never quite made it throught the loop though.

      Of course we also raced them up and down the driveway, until they got so gummed up with dirt that they didn't work any more. I wonder what they'd be worth today?

    I have expirenced a few quirks about them.

    1. There is a limited distance with the remote (15 feet or so). Many times while I was playing with the car, I had to point the remote antenna directly at the car for it to move. I am assuming that the remote does not have alot of distance, since I expirenced this problem.
    2. The turning on these cars is hard. With the small controls on the remote, it is hard to keep the car turning nicely.
    3. Also, the motors in these cars do not have munch go. Me and a few friends tried to make the car go up a small ramp (very slow incline), and the car would not go. Upon trying it farther out, the car would still stop on this ramp.

    These cars are fun, but do not try to do many stunts with them, or else they will not work that well. They do work wonders on a flat surface.

    I have some track from the old Aurora *slotless* race set (I still have some cars, but the tires rotted away - damn 70's disintergrating foam). These look like they would work great on this track (the track has a retaining wall on both sides).

    Probably not as manuverable as the old cars (the old cars would drive the opposite wheel of the lane that they were in, pinning them to that wall.)

    Had to be one of the more fun pursuits of my childhood. I recall racing with the Star Wars set - an X-wing fighter and Darth Vaders Tie Fighter. If the Tie rear ended the X-wing, the top would pop off and the Dark side won the day.

      Besides, just a motor for an RC10 approached the price of one of these cars. (However, when I broke a steering link on my RC10, I could actually replace it!)

  • I find it mildly amusing that while Radio Shack [radioshack.com] is virtually claiming to have "discovered" micro r/c cars and brought them to North America, reputable hobby stores such as this one [towerhobbies.com] have had them in stock for a while now.

    Just goes to show you what a large-budget marketing department can do for your image!
  • I wasn't paying attention when Ziff-Davis spun off ExtremeTech, and the first review I read there was for Lindows, last week.

    But just based on that one and this one, I have to wonder if they're too commercially compromised to deserve a straight Slashdot link, without some caveat...?

    Just wait....

    Someone will figure out how to put a strategically (and painfully) placed surface mount resistor or capacitor and shift the frequency up or down a bit from factory.

    Then you could race these with more than one person on the same frequency band.

    I have an amateur radio license (HAM). Technically, I'm allowed to use a wide range of frequencies for R/C or other 'remote control' use. Maybe I'll make mine work on the 2 meter band and I can control it at 100+ watts (or through a repeater)

    I'll have to be on another frequency with a friend miles away to tell me where my car is steering.
  • I got one of these after the last slashdot story on them, we had a blast playing with them at the office, but they don't keep your attention that long. On the plus side, they're neat to look at and the battery charge lasted longer than I expected, but they aren't very fast and won't run on most carpets.

    My cat,however, has not got tired of it yet, he will smack it around quite a bit.
  • 3 miles per hour..
    Wow, damn I that is some top speed. Better keep those pesky snails on leashes, you wouldn't want them embarrasing that 24kRPM engine now would you?

    At work, we have a bitchar-g racing table made from three small ikea square tables and some duplo blocks. It's a nice compact race area, but anything faster than the 1.0 motors (10,000 RPM) tend to spin out around the curves.

    • Since the small nature of thse cars force a rather bulbous body type, maybe you should chose such a body from the beginning. Yes, the car we all love, the AMC Pacer [mopar-owners-club.com].

      Poor car, designed with a "futuristic" look for a motor that never came into existence, the GM Wankel rotary.

    I have had one of these for about 2 weeks now and continue to have a lot of fun. The nice thing about it is it only annoys the dog, does not scare her. After chasing her with it for some time, she just lies down and ignores it. :)

    I have been getting around 5 to 8 minutes run per charge and the car works great on tile or wood floors, fair on a short berber and crappy on anything deeper. I also picked up the 'performance' kit and the higher end motor and gearing does increase speed with some decrease to run time.

    I also found a nice site [tomsimpson.org] that has been covering these cars and also has a nice little forum for discussing issues. There is even a post from some RS folks discussing how they have tweaked the cars.

    ...I've just put up a review of one of these things myself.

    It's here [dansdata.com].

  • I picked up a couple of Bit-Char-G units in Tokyo the other day (RX-7 and WRX - the STi model - even has the pink Subaru logo :). A quick assembly session in Bangkok over a couple of beers and vroom - I was away. Even my 4 year old son can drive the things.

    Back here in Australia we're racing them around the kitchen and, occasionally, on my work bench. I've been tempted to take them to the next dance party night and race them around the DJ console('scuse the blatant plug [quantumjelly.com.au] :)

    If you're living in tight spaces or don't have access to large "play" areas, these things rock. The guys at Subaru here are completely gaga over them (sprinting the WRX around the desk in the STi sales room - much fun :)

    Well worth the $$$...
