Spektrum DX8 gen1 Throttle Hold Timer not working
I have a Spektrum DX8 Gen 1. I don't have telemetry so I use a timer for my flights. Supposedly the DX8 has a timer setting to start when the throttle hold is turned off and stop timing when the TH is turned back on. This would definitely be my preferred method. However, I could never get it to work. Here are some pictures of the setup that I thought were relevant.
"hold" is inhibited here, but of course TH works fine when flying. I use it just like everyone else does. This is probably what truly activates TH and makes it work. The setting for the timer: 3:00 minute count down with "Hold". Proof that it is counting even with Throttle "Hold" on. Does anyone else use TH to activate the timer? and if so, how do you have it set up. What am I doing wrong? What am I missing?

What's your throttle curve in the H setting?

You are telling the timer to start when TH is on, change start to throttle and it should work.

Hmm..Okay. This has happened to me but I can't remember what I did and I don't have my Tx in front of me.
Next is check your Throttle Cut setting. What is it?

Since the "Hold" method for timer does not work for me, I am currently using the "Throttle" method for the timer. Also, Keep in mind, this is not actually "throttle", but instead it's stick position of the left stick (and again, TH switch position has no affect on timer counting). For a while, I set it to 10%. However, this caused me a problem recently. I was flying and apparently I spent too much time below 10% left stick (too much fun while stick banging) and my 4 minute timer was closer to 5 minutes of actual air time. Granted, I can adjust that % level lower to ~5or 1%... (and I have done that now) but I would much rather prefer to simply use the TH switch to start and stop the timer: - Timer running when TH off - Timer not running when TH on. which is the reason why I have created this thread, because I am not able to make this happen. I assume I am missing something because this seems like such a simple, obvious, and common use-case for the timer. I can't be the only person in history who wants a timer linked to the TH switch like this.

When I had a DX8 I set the timer to be based on throttle > 25%.
This way the timer only counts down when the model is told to consume power. Therefore will stop whenever hold is engaged.

Throttle cut setting was set to inhibit I activated Throttle Cut to 0% and "hold", it works the same as when it was inhibited. Quote:
HOWEVER, Again recall the "throttle" method in the Timer option is not actually linked to the real "throttle" percentage output on channel1. Instead, it's linked to the position of the left stick. And thus, if you are close to full negative collective when flying, then the timer stops counting, making a 4 minute flight into a >4minute flight. If you stick bang a lot (ex: full negative punch outs), the discrepancy can be a problem. Also, the TH switch has no effect. Also to clarify, my throttle curves are: N: 40 40 40 40 40 1: 60 60 60 60 60 2: 95 95 95 95 95 H: 0 0 0 0 0 Running Brain1's and Brain2's

I don't see a way to get exactly what you're looking for.
Another idea... If you choose "Throttle 1-Time" instead of "Throttle", then the timer will start the first time you raise the throttle stick above the set percentage, but then it won't stop until you press the Clear button. |

Okay, just looked at my DX8. I have mine at
Start: Throttle Out Pos: 25% I think that's what ArchmageAU was saying..

Selecting Hold in the timer settings chooses the Mix/Hold switch to activate the timer (switch on top right of transmitter) not actual throttle hold in f mode.

- Throttle (Throttle stick based) - Throttle Out (Throttle channel based) If you use the Throttle Out (channel based one), it works perfectly with Hold and Cut. (I used it for quite a while). Throttle out has been available since AirWare V1.01 of the DX8 software. (Which is why it is not listed in the official DX8 Gen 1 manual). My DX8 was using AirWare V2.06 (released 24 Sep 2012) when I sold it after using it for over a year. Quote:

I was playing with Throttle Out before my other post and it kept running all the time, even with the stick at the bottom or hold on. But I just tried it again with the value of 25% instead of the default 15%. That worked much better, and yes, that is what the OP wants. |

Anyways, Throttle "OUT" works exactly as was said to work, and is exactly what I am looking for. Of course it was there. THANKS EVERYONE! brb, I'm going to go bash my head into a wall a few hundred times for missing that. : arggg:
