Futaba crystals operate on the postive shift (sine wave starts earlier), and Airtronics(Sanwa) start on the negative shift(sine wave starts later). What this means is that....nah, it Electrical Engineering terminology, I don't want to confuse people now...

They 75, 40 and 41. The 40 and 41 are used overseas, and here in the US, the FCC has deemed them illegal because they are frequencies used by emergency services. If you do get a hold of these be warned, if you get caught at your local track with these, the FCC will shut down the track unless that channel is stopped being used. That's what I have heard from guys who organize parking lot races...

Laka

It all boils down to no the Futaba crystals won't work in a receiver made for a Sanwa/Airtronics radio system. You need to get the right crystals for the receiver in order to get the radio and receiver to "see" each other. Another option is to get a Novak synthesize receiver to go with your synthesize module in your M8.

If you need more help try to catch me at RCTech.

Your such a gearhead.

I was using Futaba radio before I switched to Airtronics M8. So, therefore I do have a few Futaba's RXs.

In order for to have Futaba's RXs works with M8 TX you must use Airtronics's X-TAL in a Futaba's RX. In my case I am using 75Mhz.

yeah komkit, i did the same thing, but i think that the question is...


will futaba rx crystals work in an airtronics reciver?

i mean i could be wrong, but that is how i saw it

and i never have tried futaba crystals in my airtronics transmitter or reciver

im sorry, my question was indeed vague: what i meant to ask was aside from the standard frequncies like: 27.255 - 27.125 - 26.995... does airtronics or sanwa have odd ball frequncies in the 26 or 27 mhz range like 26.895 or 27.235

thanks

yes, but not under airtronics, but under sawna, they offer the european and japineese crystals, but the fcc banned them for use, or hasn't approved of the use of them
