900MHz isn't internationaly recognized and 2.4GHz varies from country to country in terms of exact frequency range and power levels so the only truly universal RC band is 27MHz (and nobody with half a brain is going to be using that for giant scale :-) |

Actually, I thought something that was related to more than one country at the same time was considered "International" or at least trans-national. . thus the title that 900 mhz is an international frequency. And yes, most countries have their own little way of doing things on 2.4 ghz. . just the nature of independent nations doing what is best for themselves.
There are a lot of people holding 2.4ghz up as the panacea for all problems RF related in our hobby. Sorry, but every thing that has been thrown out so far, in the way of things that are supposed to hop frequencies, dodge other transmissions, and keep you linked to your receiver . .well . .all of them CAN go wrong, and have proven it more times than necessary to prompt a very loud Caveat Emptor for those wiching to go 2.4g. Modeller beware .. things are not as perfect as the slick advertising, slogans, and technical data overload would have you believe.
When someone invents a system that NEVER has a problem caused by outside sources, then I'll be a lot more interested. That has not happened yet, and the opposite seems to be the rule. . every system has a problem of some sort, be it quirky frequency changing, a limited number of channels it has access too, UID glitches, or just plain old "someone walked all over me with a huge signal". It happens. Still.
This is a great discussion. . I hope it continues.
