ACM/APM Futaba T8FG (Super) Mode configuration for all 6 modes

The APM WIKI has a good page to describe the setup of the Radio for switching the Mode with the RC toggle switches.

However, there was no help on how to setup the T8FG. It's not rocket science, but took a bit of try and error to set it up.

I thought I document this here so it can be linked into the WIKI along with the other Radio guides for the benefit of my own short term memory deficiencies as well as to make this easier for anybody else with the same radio.

 

Here a quick guide for that Radio to save yourself the time to play around with something more exciting:

We will use two toggle switches. In my case I used "SE" as the main switch which also controls the radio channel 5.

This switch has three positions. To be able to select 6 positions we need a second switch. I used "SF", which is a two position toggle. so 3 x 2 will allow you to set all 6 modes.

 

  1. To get the right min/max PWM output we first need to set the Endpoint of channel 5 "SE":
    Linkage Menu (LNK) > END POINT > Move to Channel 5 and adjust to have a low of 67 and 72 for your channel.
    Your display will show: "5 AUX1 135 67 72 135"
  2. To be able to add in the second switch "SF" we need to add a Program Mix which will influence the first channel "SE".
    Model menu (MDL) > PROG. MIX > Choose any, I choose 1 as it was empty.
    On the first page change the x and y Offsets (OFFS) to +25 each.
    Continue scrolling to the second page and set ACT to ON. In the next field, set your second switch. "SF" in my case.
    Set the "MASTER" to SF and the "SLAVE" to "AUX1" or whatever your Channel 5 is called (Default of the radio would be "GEAR"). You can ignore the LINK setting which should not be selectable anyway.
    So the whole page reads:
    #1   ACT OFF   SF
    MASTER  SF
    SLAVE     AUX  OFF

 

That's it!You now can control all 6 modes with your T8FG.

 

You can test the settings in the ACM/APM setup and test menu:

In CLI Mode: setup > modes

 

Flight modes
----------------------------------------
Pos 0: LOITER
Pos 1: RTL
Pos 2: ALT_HOLD
Pos 3: AUTO
Pos 4: STABILIZE
Pos 5: SIMPLE

 

Enjoy,

 

Ollie.

Any info for Futaba T7CP?

Good information, saved a lot of time, thanks.

I wonder what might be wrong? I configured my t8fg s like you have done. But if I have set RTL or AUTO in APM to mode 6 the motor doesn't run automaticly...only when I increase the throttle??? If the RTL or AUTO is set to modes 1-5 everthing works fine....Is my futaba giving some sort of throttle mix when mode 6 is on?

In Auto Mode you should have to give it throttle to start the programmed waypoints. Its a security measure. Strange the would just start in 1-5. You can always check the output PWM values in TEST mode to verify the values. if they dont match just trim them a little.

But what will happen when the aircraft is in AUTO mode and I accidentaly change the throttle to 0 or I loose my radio connection will It still continue in AUTO or RTL mode? If I put TX throttle position to 0 during AUTO or RTL will it override the AUTO/RTL´s automatic control? Is the throttle safety function only for the start phase of the AUTO flight?

Here are the PWM test results, what do you think...

Correct me if I'm wrong. You can use your SF together with SE switch to change mode right? I only can toggle mode 3 and 4 using SF switch only . How do I make SE switch usable? Do I need do the same thing as the SF settings for SE switch?

Seem like things have changed with the new T8FG firmware. In Prog.-Mix page 2 has changed. I only can choose from functions (e.g. throttle, rudder, ailerion...) but not switches like "SF". Any idea how I can get it done anyway?

EDIT: I found the solution! There is one function called "H/W" which seems to be "hardware". I fyou choose this, you can set hardware-switches insted of only functions.

Thanks for helpin myself :-)
