14mz/12z channel assignment and channel grouping ?

[medflight]

Are the channel assignments (in the function menu) and the channel grouping that everyone is talking about (607 vs. 617) related to each other? When the radios transmit in 72, the channel grouping kept the throttle and gov channels from receiving their signals at the same time. From what I've read the 617 groups ail, ele, and pitch so there is less interaction for eccpm helis. Does this mean the throttle and gov are receiving their signals at the same time, which was previousely undesireable, or am I confusing two completely different things.

I hope I understand your Question, so here goes,
Channels 1 through 6 all have simultaneous pulses followed by 7 through 9 and dg1, and 10 through 12 and dg2. so you want to use there new channel numbers like:

Channel 1 Aileron
Channel 2 Elevator
Channel 3 Pitch
These 3 channels are 100% sync'd for the swash channels.

Channel 4 Rudder
Channel 5 Gyro
Channel 6 Throttle
Channel 7 Governor, and this DOES work with the TJ pro or rev max and should work with other devices which does not behave correctly with simultaneous input pulses.

In my opinion Futaba done it right this time, Thanks Futaba

The CSM range of Gyro's don't like CH5 for the Gain. I had to put mine on CH10 to get it to work

Will be hard for him to plug it into Channel 10 on a seven channel receiver. LOL
617 is a 7 channel receiver.

"In my opinion Futaba done it right this time"

I guess this is really what I was wanting to know but I'm trying to understand it. From what you said, channels 1-6 on the 617 have simultaneous pulses followed by channel 7, which is on a seperate pulse of its own because there is no channel 9, 10-12, or dg's.

All I have heard anyone talk about is ail, ele, and pitch. I assumed the first three channels were grouped together and 4-7 were grouped together. This would have the thr and gov receiveing their signals at the same time.

[DavidH]

When the radios transmit in 72, the channel grouping kept the throttle and gov channels from receiving their signals at the same time.

Don't understand exactly what your trying to say. Even when not using the 14 channel 2048 PCM receiver. I use the same channel grouping with a 9 channel 1024 receiver as I use with a 14 channel 2048 receiver. I use the default grouping in the radio with all receivers

Channels are grouped like this using the default grouping
Channels 1-2-3 Throttle, Rudder, Gyro
Channels 4-5-6 Aileron, Elevator, Pitch
Channels 7-8-9 Governor1, Governor2, Aux

In that case completely ignore what I said. I was thinking about the G3 - which I think our friend is trying to compare to. Do the Dx's group the channels the same as the G3 or are they as the old way

[Jeff Palmer]

Its hard sometime to get futaba to answer support questions on the 14mz, its even harder to get answers on the 2.4 stuff.
As that being said, the pulses are coming from the radio either 12 or 14mz, I DO not own a 12 but, I don't think its any different than the 14MZ. I do not a own a 617 receiver, and I do not think the grouping would be any different, I have been wrong before.


But why would futaba change the pulses from the 6014 to the 617? Yes i know, stranger things have
happen!

607 and 617 receivers have differnet servo groupings, see Post #13

You are exactly right. I just didn't have my radio with me and couldn't remember the order. It doesn't matter if you are using 1024 or 2048, the order is the same. It changes when you go to 2.4, at least in 7 ch. mode. When in 7 ch. mode ail, ele, and pitch are grouped together (so I've read) just like in 1024 or 2048, only on different channels. I'm wondering if the other channels are grouped together into one group. If so, this would group the throttle and gov channels together.

Let me back up a little. When I set up a Revmax on my 12z with a 9 ch. rx., I have to switch to an aux channel for calibration. When I switch it back to gov I can't use a channel that is grouped with the throttle. To accomplish this I had to reassign a couple channels. Off the top of my head I can't remember what they are, either 6 and 7 or 7and 8. This keeps the throttle and gov from receiving their signals at the same time. This is why I was wondering about the grouping of the tm-14/617. I'm thinking that if the throttle and gov are grouped together that they will conflict with each other like before. Only difference being is there isn't enough channels to reassign them.

Yes there is difference between the 12Z and the 14MZ. They do some of the same basic programming thou.

Yes the grouping is different on the 617 2.4 ghz receiver.

The difference between the 617 and the 608 and 6014. The 8 channel and 14 channel use 2048/G3 resolution. G3 is when the transmitter is set in Multi Fasst transmitting mode for the 8 channel and 14 channel receiver. When using the 7 channel or less receivers the transmitting us set to 7 channel mode. When in 7 channel mode the resolution is basically 1024 steps and not 2048 steps.
No reason that I see for the throttle channel and the governor channel to be grouped together. Once the governor is engaged. It is on and controls the throttle of the engine. So really makes no sense to group them together.
In an eCCPM heli. It is important the aileron, elevator, pitch are grouped together and updated at the same rate.
Throttle, rudder and gyro grouped together is also better. Rudder and gyro need the same updating as throttle

So if your useing a 617 receiver the output pulses groups would be , 7-6-1-2-3-4-5 is that correct David?

[DavidH]

I am really not sure how they are grouped on the 617 when using the 7C tranny. But yes the 3 swash channels are grouped together. I am not sure what is done with the other channels. As long as the three swash channels are updated together that is the main concern.

The sequence of servo signals on the R607 is 1-2-3-4-5-6-7
The sequence of servo signals on the R617 is 7-6-1-2-3-4-5

The delay between left Aileron (1), right Aileron (6) is noticeably shorter with the R617. Especially heli-pilots may benefit from this change - improved three servo swashplate setup.

This is a copy and paste from another web site.

[DavidH]

I guess that applies when using the 7C transmitter with the 617. You can change the function of the channels on the 12's and 14 to any thing you want. So the grouping can be maximized just by changing the functions of the channels that are updated together.

David

[medflight]

I'm not wanting to change or reassign anything. Just trying to figure out if the throttle or gov is grouped with ail, ele, and pitch. If not, I can't see why it wouldn't cause the same trouble it did on 72.

[andrewt1971]

Well if i read this http://2.4gigahertz.com/faq/faq-fasst-q1058.html correctly, then the channels are sequential not grouped so you shouldn't have a problem. I think! Which brings me to my question, if the receiver sequence is 7 6 1 2... why does choosing 7channel fasst on my 12FG put the 120 degree swash servos on 1 2 and 4? even with the output sequence of the 607 receiver they would have been better on 4 5 and 6 surely, or am i missing something fundamental?

[heligio]

Ok, so can someone tell me in wich order channels should be
assigned on 607 and 608 receivers to get best results with
eCCPM helicopters?
Or wich function should be assigned to wich channel?

Thanks,
Gio.
