Very helpful, thanks!

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

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

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

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

hi,

How to program simple mode in a different switch ?

Comment by Michael R. Podlogar on June 16, 2013 at 3:48am

Hi, is this working with the T8J as well? 

Comment by Arunabha Bhattacharya on June 20, 2013 at 6:24am

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

Comment by Ground Loop on September 2, 2013 at 9:55pm

I wasn't able to replicate the six modes using exactly these values, but took the excellent idea and ran with it.

Arunabha, if I understood correctly, the basic idea is to use your three-position switch SE to select modes 2, 4, and 6.  In my case, switch SF then 'mixes in' a subtractive offset, engaging modes 1, 3, and 5.  So you set up the programmable mix to add an offset/bias in when the P.Mix mode is ON.  To accomplish this, I also had to change the endpoint mapping to push the top/bottom end around, just as described.

You want to watch the Channel5 PWM value carefully as you do this, and ensure that you are hitting all six modes, and also that the PWM value for each falls comfortably in the range shown in Mission planner.. you don't want one switch setting to be on the edge, or ambiguous.  I can tell you my values, but maybe yours too need to be different:

END POINT for AUX5 135 67   54 135

Leave the 135 values alone, and adjust the other two for the high/low flight mode to be comfortably in the range.

For PROG. MIX

I'm using -50 for both X and Y Linear offsets.

With these settings, I can easily place the PWM value in all six modes, and then configure them as needed.  I'm not clear on the problems with the Failsafe interaction, which other posts indicate might be something to do with a specific (non-Futaba) receiver.  In my case, the Throttle failsafe seems to work fine, and the flight mode is not changed.

My thanks to Oliver for the excellent idea -- I really like having all six modes available from switches.
