I dont know if this has been mentioned yet, but has anyone tried to see if the N/A and Japanese 27mhZ channels differ? I only ask this because a while ago I remember seing on a MicroSizer page that it was something like 27.045 mhz, maybe the Japanese 27 is different? I dont know. Thx to anyone who knows :p

confirmation, on the micro sizer manual here on page 4, near the bottom it says-
Carrier Frequency 27.145 MHz Carrier Frequency 49.860 MHz. Seems to be narrow band? :confused:

Here's something interesting....
 

I have a 2 speed boost Bit Char-G and my GF has a regular..,they are both 27Mhz according to the boxes, but we race with each other just fine! I was all bummed out cause I forgot to look at her box before I got mine, but it turned out it doesn't even matter?????

Strange, but no complaints here :-)

huh?
 

why are those two frequensies the only ones LEGAL in USA? what's so bad about the others?

because the 57,35 and 40 have something to do with navigation and communication things i think

dont forget things like garage door openers, car alarms, home alarms, and other communications...music!...wireless guitar amps are close i heard(may be wrong) bu t i believe 27 hz is close to our wonderful cordless phones at home...hmmm where are pagers, cell phones and wireless internet ...i really dont care its all just thoughts

The other frequencies may not be "illegal"
 

According to the FCC rules (Part 15, subpart D), just about any low power transmitter is unregulated. Several years ago, the limitations for unregulated transmitters was that it had to be under 100mW (.1W) input power. I just browsed the FCC website, and they have made several amendments to Part 15 for other wireless devices like wireless network cards and other microwave devices. Lots of technical jargon and what not, so things have gotten a lot more complicated to determine the legality of the other frequencies. I would hope that the FCC has better things to do than to confiscate harmless RC toys at customs. I mean heck, I can buy a toy wireless microphone that broadcasts on the FM band (88-108Mhz) that has more range than a Bit! "Real" RC gear is a different story, because the transmitters have a higher power output.

A Bit clone that I purchased had a sticker on the box that claimed it was FCC compliant under Part 15 rules, it was a 40Mhz car - and it was purchased at Kay-Bee toys, a larger importer.

Just another side note, the Bits and other "toy" grade RC cars use different frequncies for running multiple cars because their receiver circuitry is not selective enough to allow separate "channels" within the same frequency band like the "hobby class" RC's. Thats why some people may experience problems when running frequencies that are close together.

If that's the case, what are b40m, b45m, b35m, b57m, used for in the US?

Got a tomy multi-band controller. It has a switch foooooor: 1. For regular unboosted cars in the japs 4 bands (27,35,45 and 57). 2. For boosted cars, witch are run on a different freq. 3. For boosted cars to be run without the boost function.

Add this to some of the extra bands on the market and that makes 10 usable cars at the same time that I know of.
27mhz
27mhz (boosted cars)
35mhz
35mhz (boosted cars)
40mhz
45mhz
45mhz (boosted cars)
49mhz
57mhz
57mhz (boosted cars)

VERSE interference of course.

Any more freqs?

why don't people do what arceeguy did?

I got a Panther clone (These things suck they're not worth the 10 bucks they cost!!! Don't waste your money on these things!!! The rubber tires are so hard they crack and the motor is wired with wire as thin as ZipZap SE's reciever antenna's are!!! Not to mention my MicroSizer with a 1.6 motor is faster than this Panther which supposedly has a 3.6!!!) 35MHz and it interferes with my 27MHz MicroSizers...

Thanks for the info. The only reason to get a clone bit is for the different frequencies. There's always one major fault with all bits.

If anyone doesn't know, the new Super Bit Char-gs have the same frequency as the original Bits but the frequencies can be changed to different types (example 40mhz A,B,or C. or 27 A,B,or C. these are just examples. there are more frequencies.) In the USA, the "super" microsizers have only 27 and 49. But as I said, they come in a,b and c. You can change the type on the controller but not on the bit.
