Perfect! Thanks for screenshot.
Now it is OK. It was rather only cosmetical issue, because throttle signal is not passed to the ESC at all in case your TX was off before the unit was on.

Ahh cool.. No probs..
I am still running my throttle cable from the RX (per 1.24) and can't be bothered rewiring it!!
Lets see how Jmann goes with his save testing..
Now you can wrap it up for afternoon!!
Oh & is it ok to fly with test23?? :)

While you're here..
A quick question that I have been thinking about.
I have finally sorted out a problem, with my pitch setting.
You may have noticed that in some of the screen shot's my pitch 0 value was actually 7.
I have fixed this by changing the PPM center value in OpenTX from the standard of 1500 to 1545.
Any thoughts?

Cheers,
Yak.

Yes, you can fly with test23 without any problem.

Changing center pulse for collective channel is OK and correct. There are differences across all the tranmitters and receivers.

Cool, I was just wondering why pitch was different.. (1542)
All of the others are 1500 and all (except throttle) even have the same endpoints.
Just something to check :)
If Jmann is checking this, whats your pitch setting?

Thanks,
Yak.

Good morning gents! Can't wait to test out the newest one and see if all is resolved!

The pitch channel has to be adjusted in the Tx always. I'll get you my values in a big after I get out of bed haha.

Test 23:

- No issue opening log or saving.
- When Tx is powered off and heli is either not plugged into computer or plugged in, heli does fast twitching on all servos until link is restored.

My Failsafes are set to "No pulse" in Open Tx

My Pitch center is 1500us as I changed the subtrim instead... In Servo tab It is set to 6 on the subtrim with the max limit at 89 and min limit at -77

Hmm, thanks.
Could you change your failsafe settings? At least for throttle channel? I believe it could fix the problem.

Sure,

The weird thing is, the issue is not present with the original 1.0.25 firmware with my failsafes set to no pulse.

I'll adjust them in opentx to a specified value.

You are quite correct.

When I set the failsafe values in Open tx to Custom and just put channel 3 (Throttle) to -100 It displays no issues.

Very weird.

However, it also activates rescue. Not sure if that is a good or a bad thing. Could be nice if I loose signal but it will also cut throttle so may cause more damage. I think I just have to adjust channel 5 to be a positive value when failsafes go on.

Thats because failsafe does not worked at all with Tarantis with 1.0.25 :(
