12 FG spektrum?? is it out yet?

[jet78]

Greetings,

Does anyone know if the 12FG skeptrum version is out yet? I've been on the futaba website but it doesn't
seem to say anything about it... maybe I'm blind .... DOH!

Release date on Tower Hobby recently changed from early October to late October.

12FG skeptrum version

I believe you can use the Spektrum 14mz module in the the 12FG but I suspect you mean you want the Futaba FASST 2.4GHz Tx module. Note that the 12FG is not an integrated 2.4GHz Tx like the DX7 or X9303. It is a module-based Tx so you have a choice of which brand of 2.4GHz module-system you want to use, XPS, Spektrum or Futaba/FASST. Only the FASST module will give you all 12 channels, 2048 resolution (if the 12FG has it) and leave the trainer port unoccupied. Both the XPS and Spektrum modules use the trainer port. The Spektrum one will give you either 8 or 9 channels (I cannot recall) and the XPS module will give you as many channels as the 12FG will output in PPM mode, which could be 12 if it is the same firmware as the 12mz.

And just to clarify Kenneth (you're clearly following this 2.4ghz scene closely)

Spectrum binds the RX to a specific model in the TX?
Do Futaba and XPS have similar functions?

XPS and Futaba do the channel hopping thing,
Spectrum does not (but it wont go live if the channel is in use)

bummer, I was really thinking to get my hands on one...
in that case I wanted to switch to JR but the 12X also has no news......

maybe I'll wait till the 12FG 2.4ghz........

Spektrum has "ModelMatch" in the integrated Tx (DX7, X9303, 12X) which does indeed bind the Rx to specific model memory but cannot do so in the pluggable Tx-modules since the modules have no way of knowing what memory is selected in the host Tx. Same applies for XPS modules and for FASST modules as far as we know so far.

XPS will have one step further in their own Tx where the Tx will automatically switch to the correct model memory for the bound Rx. No news yet on when their own Tx will be available.

Right.

Spektrum is DSSS and chooses two clear channels at boot-up and as you say, won't actively transmit unless it can find two suitably low noise channels first. Once the channels are chosen they are fixed until the Tx is power-cycled.

XPS is DSSS and chooses a single clear channel at boot-up but it is the Rx that chooses the channel. If the noise floor at the Rx rises too fast or too far it will initiate a channel change to an alternate, lower noise channel.

FASST is FHSS and hops channels every 2ms from what Futaba says.

Great info, thanks!
I'm getting excited about XPS
