3689408226?profile=originalThe 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" 3689408226?profile=original
  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. 3689408243?profile=original
    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  OFF3689408351?profile=original

 

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,

  • Can someone explain the theory behind this mixing? And also how I could go about doing it on the 8J?

  • Hi, is this working with the T8J as well? 

  • hi,

    How to program simple mode in a different switch ?

  • Thanks for the write up Marco, I've now set up my T8FG to the same configuration.

    I'm sorry Veikko, i haven't tested the "joystick controlling" feature.

    Hi all, i've found a good combination for the T8FG with the "flight mode 4" to "RTL (right for the "failsafe function"), just follow this step:

    - go to "LINKAGE MENU"

    - go to "FUNCTION" and in the channel 5 assign "AUX1" and select "SE" switch for this function

    - exit and go to "END POINT"

    - in the channel 5 called "AUX1" set the sx end point to "50" and the right to "30", your display will show: "5 AUX1 135 50 30 135"

    - exit an go to "SUB-TRIM", set "AUX1" to "-170" (default is "0")

    - go to "MODEL MENU"

    - go to "PROG. MIX"

    - enter in the first program mix, go to the second page and enable the mix from "INH" to "ACT, select "SF" switch instead of "--", set MASTER and SLAVE to "AUX1 (all the rest to default)

    - go to the first page and select "POINT" instead of "LINEAR" and set this value: 1/2/3 at "-100", 4/5 at -50

    - exit and go to the second program mix, in the second page enable the mix from "INH" to "ACT", select "SF" switch instead of "--", set MASTER and SLAVE to "AUX1 (all the rest to default), in the first page set the second value (starting from the top) to "+100" and "Y" to "-100"
    , leave the other two to "0"


    In the planner set this flight mode (respect the order) and use SE and SF switch for change the mode:

    Flight Mode 1: STABILIZE
    Flight Mode 2: ACRO
    Flight Mode 3: LOITER
    Flight Mode 4: RTL
    Flight Mode 5: ALT_HOLD
    Flight Mode 6: AUTO

    Please verify the right pwm value, there must be a good margin (at least 20).
    Enjoy!


    Bests, Marco

    Hi Oliver, all is clear, but you have to consider the internal APM failsafe: if the rx stop to work ArduPPM automatically switches the flight mode to the number "4", then it is highly recommended to put on this flight mode the "RTL" (with autoapproach or autolanding enabled).
    This of course applies not only to T8FG but for any tx.

    Bests, Marco

  • Very helpful, thanks!

  • mine works with slave as gear not aux and thanks again oliver
