RE: why is 2.4ghz so good
27 mhz has tones of interference because there is little restriction on it and can be used for everything from cb to junk rc.
75mhz is designated land use.
2.4 ghz isn't really better, actually the frequency is garbage, the wave length and power output has next to no material penetration so you have to use multiple antenna and even multiple external signal amps in some systems because the signal only penetrates the model so far. the technology incorporated into this band makes it more convenient, no crystal to buy or worry about having your plane shot down by someone on the same frequency.

Well all of the above is true, but I'd say there is another distinct advantage; speed.... [sm=thumbs_up.gif]
The control response of the model is so much faster and you have a much more "connected" feel with the model due to the speed at which the data is sent from the tx to the rx.
I sometimes tell people it's a bit like comparing the difference in Internet access speeds between a dialup modem and broadband... lol

Long live the garbage! -I wish we had had it 20 years ago.

I must admit, I too fell into the I don't need 2.4 club until I experienced it. The connected feeling is absolute and the protection it offers is encouraging.

No impounding transmitter at large events, Small antenna, no crystals, no shootdowns, easier to compile a matrix at racing events, no waiting for your pin at the club field, piece of mind from shootdowns with large expensive models.
The upside is so large I find it difficult to lend any creedance to the nay-sayers. It is the most wonderful thing to happen with radios since digital proportion.

No crystals there either.
The TX will not go on air if the channel is occupied, so I can't shoot anyone else down. (Now, if just everyone would fly Multiplex, the worlds would be good!). Not quite the same level of protection, but had 72 gone to onboard scanners/channel busy detectors as had Multiplex, no shootdowns there either.
So, looks like the only clear "win" in your statement is no need to wait for the pin/impound . . . . the rest are not unique to 2.4 . . .

Hmm, comparing to my Multiplex Evo . . . .
