I am trying to program my 12 FG for a 3 engine model. In Function menu I assigned Throttle, Throttle2, and Throttle3 to channels 1, 2, and 3. That works fine. When I activate the Throttle Cut and Idle down features they only work on Throttle channel 1. What am I missing? How do I get Throttle2 and Throttle3 to cut and idle down also??

Thanks

The Throttle-cut and Idle-Down functions only work on the Throttle channel.  Throttle2 and Throttle3 would not be affected.  The easiest way is to just use three instances of "Throttle".  You'll be able to set up the ATV's independently, as well.

Bax,

You mention ATV, but 12 FG uses AFR to adjust throw.  Is there an ATV adjustment somewhere that I am not aware of?

When I use 3 instances of Throttle, only one AFR is provided.  The throttle AFR affects all 3 channels assigned to it equally.  There is no way to set curves for each channel individually.  How do I adjust each throttle response curve individually??

By the way, what does "AFR" stand for???

Thanks,

Bryan

Sorry, I meant "AFR".

"ATV" means "Adjustable Travel Volume"The amount of travel the CHANNEL will move. Also known as the "End Point". The 14mz has it listed as "ATV (end point)". "Travel" is how much the channel moves when you move a control from end-to-end. "Limit" is the total amount of travel a channel will move when it's influenced by a mixer.

"AFR" means "Adjustable Function Response". This adjusts the FUNCTION. You can have several channels under a single function.

When we mentioned that you can use several instances of "throttle", we meant that you would set up, for instance, channel 1 as "throttle", channel 2 as "throttle", and channel 3 as "throttle". You can then go into each channel and adjust their AFR curves.

If you set channel 1 as "throttle", channel 2 as "throttle2", and channel 3 as "throttle3", then you can adjust only the throttle AFR, because the system assumes only one function with three channels working under it.

Understanding that AFR means adjustable <u>Function </u>response clears things up a bunch for me.  Thanks for that insight.  However the description you gave above is not how my 12FG is behaving.  After receiving your reply I programmed this example:

In function menu I made these assignments:
Throttle function to channels 1, 2, and 3,
Throttle2 function to channel 4,
Throttle3 function to channel 5,
Throttle4 function to channel 6,
And all to control J3 and trim T3.

Here is what happens:
The AFR menu provides a curve for each Function, not each channel.
Changing Throttle AFR changes output of channels 1, 2, and 3 together.  There is no way to adjust the curve response of these channels separately, but throttle cut and idle down do work for these channels
Changing AFR for Throttle2 changes response of channel 4 only.
Changing AFR for Throttle3 changes response of channel 5 only.
Changing AFR for Throttle4 changes response of channel 6 only.
By assigning channels 4, 5, 6 to separate throttle functions I can adjust the curves for each of these channels separately, but throttle cut and idle down do not work for these channels.

The End Point menu provides a Travel setting for each channel (not function).  Here I can tweak the total throw of each channel individually but not the curve response.

It makes sense that throttle channels have to be assigned to separate functions to allow separate AFR adjustments.  And I assume this is why Futaba provided 4 throttle functions, to allow up to 4 individually adjustable throttle responses.  It does not make sense that cut and idle down do not work for all throttle functions?

So I am still left with my original programming problem.  How can I adjust the response curve, not just end point travel, for each throttle separately, but still have throttle cut and idle down on all?

By the way, I have loaded latest software version 1.6 into my transmitter.

Throttle cut and Idle-down only work on "Throttle".  To get the same operation on additional throttle channels, you'll have to use a pmix set as an offset, and then set to the same switch as function you want to work with.

If you set all three of your engines to work as "throttle", then the throttle-cut and idle-down functions will work on all of the channels.
