RE: Futaba 12z
Interested on it, but not sure want to use G3, since there is some controversy on G3 noise rejection capability.
That will make it a 10 channel PCM or 12 Channel PPM, right?
Or will it be as above, but some extra channel if adding the extra decoder?
Thanks

The new 5114 rx allows you to change the sensitivity level. If you are a real noisey area you can change the rx mode, your will not be running 2048 resolution when you change the mode, I believe they said it will be in the area of 1600.
I have been running the 12Z/G3rx in my contest IMAC planes since April of 2006. Never had a problem.

RE: Futaba 12z
Thanks for the info. My software is 1.0.4/1.31 so is way out of date - I got it at Christmas and did not expect it to change so soon. Will have to try and update. I am trying to get to 10 channels (preferably proportional) with a Weatronics rx. I already know that the Weatronics does not support 2048 but so far I have only got 8 channels working. I have tried scrolling down but can only get to VC1 - 4; possibly I need to update the software. Will keep trying

RE: Futaba 12z
Does anyone know if this radio is capable of servo slowing? 8 weeks? Bax just mentioned that they would here maybe end of the year. 12Z or 12FG are on my short list.

I saw it somewhere on Tower's website but I do not see it now. Futaba rarely pre-announces, and I know why, they take forever. I would think early next year is a safer bet

RE: Futaba 12z
Thanks, that is an amazing manual. I've held this radio and it is sweet. I'd love one.
Looks like servo speed and much more is possible.
Matt, what you say is probably true. I'd like to hold out for a real step up into a radio I can use for a long time. The other offering are intriguing as well.
The MPDX-1 is really really cool looking, I've read the manual available at tower and seems like and endless answer to many extra channel dilemas.

Yes, it has servo speed setting. Page 60 of manual.

RE: Futaba 12z
Well I checked an MPDX-1. It does look like you can get 8 channels from one channel, all individually controllable with any switch, knob, even trim lever, each with reversing and ATV. No mixing, but they are not suitable for any flight controls anyway.
They do however look perfectly usable for everything from gear and brakes all the way to throttle, turbine auxillary control, even flaps, speedbrakes, etc. And you don't have to use that G3 receiver, I used an old plain jane DP149. Even that 9 channel RX lets you get 16-23 (!) channels of control.
I have never seen anything like this and I have spent years squeezing functions into limited channels. This is a whole new deal.

Need a failsafe setting for the turbine, so not sure how many channels you can get with the PCM and decoder in an plain DP149 or the G3 receiver.
Thanks

RE: Futaba 12z
Hi Edgar,
Good point on the failsafe shutdown, I will have to check as the MPDX-1 has onboard failsafe settings. I will try it.
It works with G3, PCM1024 and PPM. I have been assured it will work with FASST when it comes out (I would not have bought it otherwise).
I assume it would work with spektrum too, under PPM.
Regards,

RE: Futaba 12z
How does the MPDX-1 work? Sounds like you are saying that you could have 8 different servos plugging into the unit, and then the unit plugs into ...say ... channel 7 or whatever. Now I can control all eight servos with switches/dials/sliders or whatever individually??? Wouldnt whatever switch is assigned in the radio to control channel 7, control all the servos plugged in to the MPDX?? I just dont get it. Or does it just work like a giant matchbox where you can set individual end points and subtrims for each servo but you still control them all with one input device ie; joystick, switch or slider?

RE: Futaba 12z
I think you can control each channel individually. This is because the transmitter knows that the channel is being used for an MPDX-1 and adjust the signal accordingly.
I assume the resolution suffers in order to accommodate the information for all MPDX-1 channels in one normal channel.

RE: Futaba 12z
Hmmm .... I wonder how the transmitter would know? Is there somewhere in the transmitter program where you "tell it" you are using the MPDX? I dont know thats why I ask.
Thanks!

I turned on this function on my 14Z program but only connected a servo to the Rx channel that I set for MPDX-1 and the servo turning by itself with no control. This is because Tx sent eight encoded servo signals to one Tx/Rx channel and MPDX-1 decodes this mixed signal to eight independent servo signals. This is not magic, just think about this is similar to a single DCS wire between Tx/Rx that can transfer all channels' data from Tx to Rx and then Rx spray this data to each individual servo channel.

RE: Futaba 12z
Hello,
Your description of how it works is right on, but one correction, the MPDX-1 does indeed work with the 12MZ as well, I use it with a 149DP reciever
In addition, the 12MZ has the same number of channels as a 14MZ (12 + 2) when using G3 modulation

Seems like a good way to get more than 10 channels, in PCM, and not use G3
Do you know it it will work with the cheaper 12FG?
Thanks
