Dave that's alot of action going on there. As far as using the MPDX it's only going to be used for ON/OFF, This will (hopefully) give me the 1 extra channel I need.

Pete

Thanks a lot nargargle

I will check if moving the model, the ailerons and rudder try tu return to neutral

I checked both MPDX ports and they both work as on off..

Pete,

Not sure we 're on the same wavelength... the MPDX-1 is a separate device that plugs into channel 11 or 12, and turns the one proportional channel at full update rate into 8 separate proportional channels at a fully proportional but slower update rate.

For 2.4GHz Futaba systems, you need the newer HS services receivers, it was not supported by the original "FS" receivers. You need the latest firmware update for the 14MZ TX to set up the additional channels .. that as been out for a long time (1-2 years).

Perhaps you are thinking of the two on/off channels (DG1 and DG2, channels 13 and 14) on the 6014? Those continue to be available an are unrelated to the MPDX-1. I have set up and played with the MPDX-1 and it is definitely full proportional, and even with the slower update rate is reasonably responsive.

Dave

I just want to share the setup for my Skymaster-Xtreme F-18C Hornet.
I'm using ailvator mode on Futaba 12FGA 2.4GHz FASST transmitter, it comes with 14-channel receiver and here’s the following setup and function:
Ch1: Elevator 1 (port side), 45mm up and down with -50%expo, aileron 35%
Ch2: Elevator 2 (starboard side), 45mm up and down with -50%expo, aileron 35%
Ch3: Rudder, approx 60% drive and -40% expo
Ch4: Aileron 1, 15mm throw with -40expo and 30% flaps mix on landing
Ch5: Aileron 2, 15mm throw with -40expo and 30% flaps mix on landing
Ch6: Throttle,
Ch7: Flaps 1, 25mm for takeoff and 50mm for landing
Ch8: Flaps 2, 25mm for takeoff and 50mm for landing
Ch9: Landing gear,
Ch10: Spoiler,
Ch11: Wheel brakes,
Ch12: 3-position switch engine aux ( shutdown, standby & smoke option),
Ch13: Rx Voltage monitor (no Tx control) and
Ch14: Rx Backup power supply
All surface control has servo reduced speed setup to prevent it from stress during sudden stick operation.
I’m also planning to put aileron on the flaps only for landing mode condition so I would have high control output on almost stall speed on landing.

Happy flying,
John

shoot 14 isn't enough....BW had the idea many years ago..when he was working on his 24 channel system! Never but never have too much altitude..power or channels)

Dave/All

I've a 12Z 2.4 of course. I need 14 channels for my F-14 if I wish to add smoke and use my tail hook and of course I do. Was going to purchase a 14MZ but I'm not rich like you guys so do you know if I can take advantage of this MPDX-1 deal or simply use the DG1 and 2 slots on the HS receiver? And yes, I still have a few older FS receivers; can I use these features on it as well?

Thanks.

Oh yeah, if I can, what do I need to do

Hey DJ,

It's up to you... I believe people have said that the 12Z can "talk to" DG1 and DG2 which are the non-proportional (meaning, they are two postions only .. full travel one way, or full travel the other way) channels in the 6014 Rx (the FS and HS both have them). They are channels 13 and 14. If that's enough, that's the simplest way to go.

You can use the DG channels for functions that don't need endpoint (ATV) adjustments. You can, if you wish, add a device like a matchbox or the futaba equivalent on the output to manually adjust the endpoints.

If you want to use the MPDX-1, it has to be a HS version receiver it is said not to work with the FS. I have not tried it...

What happens is this: you give up channel 11 or 12, your choice, to run the MPDX-1 .. but gain 8 new fully proportional channels which the MPDX-1 puts out for you.

Personally, I would not use the MPDX channels for primary flight controls, but they are great for supporting functions, and have essentially all the functions of the rest of the channels (e.g. ATV, failsafe, speed), just a slower update rate, meaning they respond a little more slowly to control inputs. I have played wih the MPDX quite a bit and it's really quite a nice unit.

I can assist offline if you wish...

Dave

U R da Man, Dave...I knew I could count on you And yes, I will take all the assistance offline, but let me just ask you this one real quick. How does one use the 8 other channels via the tx? I mean, how do you control those channels if controls on the tx are already accounted for?

But yes, the DG1 and 2 is all I should need.

Thank you, Sir.

The access the additional 8 channels, you go into the FUNCTION menu, and once set up properly,there will be a new sub-menu on the channel assigned to run the MPDX-1. When you open that sub-menu, you can assign a control input to each of the 8 channels on the MPDX-1. There will be similar sub-menus on other programming funcitons, e.g. servo reverse, ATV, etc.

Take a look at the MPDX-1 manual online on the Futaba website: [link=http://manuals.hobbico.com/fut/futm4158-mpdx1-manual.pdf]http://manuals.hobbico.com/fut/futm4158-mpdx1-manual.pdf[/link]

After downloading firmware update 1.6 and installing it into my 12FG, Multiprop appears in the Linkage menue, you then have to assign a channel to the MPDX 1 or 2 and the extra channels appear, the assignement appears to only work on the main channels and not on DG1 or DG2, I am still looking into this to see if it can be moved to them.

So we can say that the MPDX-1 does work on the 12FG, glad that is cleared up as I bought two of them on the off chance it would work.

Mike

Mike,

Already been down this road .. the MPDX-1 can only be used with channel 11 or 12. This makes sense if you think about it .. it has to encode 8 channels of full propo information (presumably serially) into the channel it takes over, and DG1 and DG2 are only on/off.

A strict reading of the 6014 HS manual says that when the data jumper is installed to enable 11 and 12 to be MPDX-1 "multipropo" channels, that BOTH 11 and 12 are not usable as normal channels.

I have my MPDX-1 in channel 12, and at least from empirical testing, channel 11 still functions normally. I've been meaning to ask the Futaba guys about this...for now I won't use it.

Dave

ww2birds

Unfortunatly you are right, they can't be assigned to the DG1 and 2 outputs, as you say it make sence as they are only switching channels, still I now have it all working and have 26 channels to play with.

Mike

Dave, my Brother

Where can I obtain Afterburner Lights? Don't want you and Andy having all the crowd pleasing glory

Thanks...

Hi DJ,

I believe the usual source is Dreamworks. I am waiting on a set now for my Yellow F-18 .. seems to be taking a while, maybe the factory is on vacation or something! Todd + co promised to email when available .. as you know they are a first-rate outfit, so I am sure they will.

If others know of an alternate source that would be great, but I do like the ones Todd sells that Andy has in his F-15 twin.

Dave

Hey Mike, did you test it in FASST mode or PCM/PPM?

Guillermo

FASST 2.4 is all I operate now days on my worth saving airframes and Spektrum if I don't mind loosing them occasionally.

Mike

Thanks Mike

I have 12FGA FASST and I just wanted to be sure prior to get the new 6014HS receiver and MPDX-1, that it will work with my transmitter.

Now I am going to get the new receiver and the MPDX-1 and download the 1.6 software version as you did.

Thanks again

Guillermo

Glad to of been some help.

Mike
