Safe safety switch

[tmc]

Hi everyone and since this is my first post here, thanks to the developers all around!

to my problem: I've setup the "thr cut" switch to be my safety switch for throttle stick.

CH3 S !THR -100

This works nicely, but the problem is: if i have the throttle stick at a high level and flip the "thr cut" switch accidentally, i don't want the motor to go nuts. Rather i would like it to be only switched on when the "thr cut" switch is activated while the throttle stick is at <-90%. I think this should be some sort of flip flop option and have tried the following:

custom switches:
SW1 v<ofs CH3 -90 THR
SW2 AND ON SW3 THR
SW3 OR SW2 SW1 ---

and of course safety switch:

CH3 S !SW2 -100

SW2 and SW3 should "remember" their state as long as THR is "on". The simulator does not play along (SW2 and SW3 are switched off when CH3 >= -90), but when i program the tx with this, it does seem to work. Since this is the throttle control we are talking about, i didn't want to test it on a life plane until i knew what was going on.

Could someone enlighten me as to how to do what i'm trying to do?

thanks and regards.

Which firmware (er9x or openTx)?
What you want is a "STICKY T-CUT" or sticky throttle cut. It's on the forum somewhere! You should also find a template for it in the templates menu.

i'm guessing. You're using er9x as firmware. Don't know which version though. Go to templates and you'll find one called "Sticky Throttle Cut". Try it. Be very welcome to the forum. I hope you are a beer drinker. If not, you will be soon.

Wow thanks guys. That was fast and it works nicely.

I couldn't find much documentation regarding the custom switches as well as the safety switches. The documentation just mentions both very briefly. Specifically, I would like to know if there is any difference between SW1-9 and SWA-C. Also, what does the "type" column in the safety switches (second column being "S", "A" or "V") mean?

oh and i am in fact using er9x version r790 (28.04.2013)

S - Safety Switch
A - Alarm (Audio alarms like beeps and sirens, etc)
V - Voice. But for this you need a voice module..

I mentioned the er9x version because the er9x-frsky version of the fw doesn't have the templates in it due to lack of flash memory. So, they were removed..
