Spektrum DX7 Kill switch
Тәжірибелік нұсқаулар және стиль
the other day, as I was trying to get the battery out, my jacket caught the throttle and luckily the prop was a few inches farther from my face; otherwise, my face would of been swiss cheese. Anyhow, this vid shows a quick way to implement a "kill" switch with the DX7. Credit goes to rcgroups thread; however, I wanted to do this vid because those instructions on rcgroups were poor and it took me a long long time to figure it out.
a few things to remeber:
#1 safety - Remember to have someone hold your plane with the prop away from anyone; or like myself in the vid, take the prop off.
#2 I found that on some of my models I had to rebind the rx, otherwise it did some quirky things, so always rebind after doing this.
#3 on some models, I had to adjust the throttle trim to a much higher level otherwise the throttle was a bit off.

I am going to guess the "2P" on the AUX 2 2P menu item means 2-Position Switch. Great share, I will be using this as a safety backstop on my new-to-me DX7 I got today in a "lot" purchase.
Thank you. I should have done this a long time ago. No more models flying off the table.
Great information!!!! Thank you for sharing.
Thanks for this, did the job nicely and I've applied to three models on my Tx. Some forum posts on this topic just confused me. BTW, in the input select screen for Aux2 2P SW means 'two position switch'. I think.
That is pretty neat, thanks!
you're welcome! Yep...those props are not nice! glad you found it useful.
useful, thanx!!

Graham Bate Sorry. I'm all electric...so I don't know.
Why must you use mix 6 or could you use other mixs I'm trying to figure this out for my nitro plane instead of using down trim to kill it

@@jamesgregory7672 Unfortunately due to my career i haven't been able to fly for about 5 years. However I do have my radio so I will do my best to remember and hopefully help you out. In my radio I used MIX4 and set it to THRO>THRO. Then i set the upper rate to 0% and lower rate to 38% (38 if I recall correctly was minimal throttle for my engine to run). I set the SW to GEAR and had 0 offset. Once done the motor shouldn't run in one switch position and once you flip the switch it should start. I really hope I am correct and that this is able to help you out. Let me know the results if/when you test it that way I know for sure and someone else doesn't read this and gets lead the wrong way. Stay safe and have a blast flying!!

@@RCCFanatic it worked out perfect for killing my nitro thanks man legend :)
It's been and I can't really remember, but if memory serves me right any available mix that allow you to control with a particular switch would allow you to do this, and on mine the switch I wanted happened to be mix 6.
