Spirit System

+1 on this. Would like to know if after 5 seconds, does the unit go into slow-spool up as opposed to bailout spool-up? For big autos, this could be a problem!

For now it is not possible to change the time. Good compromise was needed so it can't negatively affect normal usage for all customers.
We want to make the settings as easy as possible so adding next parameter is not the best way for us.
Altough we will consider the parameter and hopefully find the best solution.

Is autorotation enabled if the throttle is dropped to zero or has it to stay above zero?

It is still enabled until preconfigured Autorotation Bailout period will expire.

So if you will set 10s for the bailout, bailout can be activated anytime in these 10s even if the throttle was at zero.

Bailout, will work great on Nitro. But on Electric, remember once ESC sees 0% ESC Build-in Spool-up will kick in, even Spirit likes to spool faster on Bailout.
You need to adjust ESC as well, to meet this, if possible......

Now, Autorotation Bailout again with V 2.0.0 - I'm using the Spirit in combination with a CC 80 Edge HV. Which way do I have to go?
1. Using the CC internal bailout function - but then the throttle has to go below 1.2ms

2. Using only the Spirit functionality - and to increase the Head Speed change rate in CC?! Otherwise the RPM comes up not very fast. And is it correct that at 1.25 ms the motor does not stop?

Many thanks

With new Version 2.0, Auto rotation Bailout with CC Edge works fantastic now, Spoolup 10 Seconds Bailout 3 Seconds.
I keep this updated in regards to latest feedbacks, 17th April 2016

From a principle point of view, it should work this way with any ESC with integrated Bailout functionality.
If your not looking for Bailout but just Governing via Spirit, don't program the mixer in your TX.
Configure the rest, so Bailout can be enabled later by just adding the mixer in your TX (transmitter).

You got two options to get Gov functionality:
a) Use ESC in Multirotor Mode, which leaves full control to Spirit GOV, any wrong manipulation (like deselecting Gov in Spirit) will strip gear.
b) Use ESC in External Gov Mode with build-in Autorotaion Bailout, which leaves Spoolup and Bailout control to ESC and Spirit combined. I prefer this one, as its more safe for users.

ESC (Castle Creation Edge) ESC Preperation:
1) Configure ESC in Vehicle Type : External Governor
2) Enable Autorotation
3) Initial Spoolup: 8 (This is for Spoolup)
4) Rate Change: 20 customs (This is for Change and Autorotation Bailout)
5) Optional, adjust Startpower under tab Motor for the first revolutions I had to lower on 12S (15) , 6S (59 medium) was fine.
6) Enable AUX Wire for RPM out, If there is no AUX, use 3rd party Sensor to tell Spirit current motor rpm.

TX Preparation:
For Spirit 12% is Bailout threshold, above 50% GOV engaged
1) Make sure your TX matches 0..100% on Spirit Diagnostics from Hold to Full
2) Define a Mixer on a Switch, I call it Autorotation Training Switch, If I enable this Switch, Hold will not go below 15%
Pending on TX how you do it. On my DX 9 I use Switch E (Mix E-> TRH 30% ) On Flightmode Hold only.
Test it on Spirit Diagnostics, you should see normal throttle out, but if this Switch is enabled, see 15% on Hold.
Well with this, you tell Spirit, as well as ESC to activate Bailout.

Spirit with Firmware 2.0 Preparation:
From a conceptional point of view. Spirit unit sees whats coming from TX, this is telling Spirit what to do. Spirit than adjust what it's sending to ESC pending on min max Range. Now we have to adjust range to meet ESC requirements.
On my CC Edge setup, ESC likes to see the following, with activated Autorotation in Gov Mode: OFF > 1000us, Bailout 1000us...1100us, Full ..1900us. If we do the calculation, 1100us equals 11.11%, while Spirit requires at least 12% for Autorotation, so we need an overlap of this two ranges to be on safe side. On TX we mixed up to 15% so we done there, now we have to match on whats send to ESC. What we do, we lower the min, to get higher % value to stay within ESC Bailout window. On Range 900..1930us, 15% will give 1054us, that's perfect. Remember below 50% it's pass through adjusted by min/max range.
1) Spirit Gov. Min Range: 900us this is very important
2) Spirit Gov. Max Range: 1930us
3) I use 200Hz, works with 333Hz as well but does not make sense.
4) Spoolup Rate: "fast", try "very Fast" later, I use "very fast".
5) Spoolup rampup: 140us, this closes the gap from 900us to 1100us for immediate revolution after Hold release on initial Spool up.
6) To get max overlap on Spirit Bailout and CC Bailout, Enable Switch on Hold and increase MIX from 30%, till Motor starts to rotate, than lower by 2% I ended up at 38%

Troubleshooting:
To monitor ESC signal, add Servo instead of ESC or use Y-cable and add Servo. You should see initial position and coming out of Hold a Jump (Spoolup-rampup), followed by slow moveup to full position.

Tuning:
Try very fast next, if you looking for even faster speedup, rise Spoolupramp up to 200us, this will give you 2-3 Sec Auro Bailout. As this little jump is also added on top, coming out of Bailout.

Hope it works fro you as well, I enjoy new Bailout just today with my SOXOS 700 12S Setup with CC Edge 160HV and SOXOS 600 6S CC Edge 200A a lot, let me know.
Big thank to Tomas

Many thanks for the explanation - now I know why it didn't worked. I set the External Gov mode instead the Multirotor mode.

But I have still some points and questions:

1.) I also prefer option b.) - It is saver and in option a) the motor will not stopp totally - correct?

2.) In the Spirit manual is stated, that the Bailout is activated if the signal does not drop below 1.25ms - 12%. From my point of view 1.25ms is equal to 25%, if I take a range from 1 to 2ms. What is correct - 1.25ms or 12%? I assume 1.25 ms

3.) As I know, the Bailout is activated in the CC between 1.1 and 1.2ms - thus it would be save to take 1.15 ms



4.) If I assume the 1.25ms to be correct, I would have to set a range from 800 - 1950ms in order to get with 30% (to be savely above 25%) a value of 1.150ms which is in the range of 1.1 to 1.2 ms.


Am I wrong? The best argument is that it works for you as decribed [emoji1]

I think Spirit input range 0..100% is 1100..1900, where 1250 would be close to 12%. I can validate this tomorrow.

Governor is controlled by the input from your transmitter - which is configured to match 0 - 100% range in the Diagnostic tab.
The ESC range can be changed in the software to whatever you want, so 12% can be simply value you wish to be at the output.

Both numbers (% and pulse) are relative for the ESC. If you move the bottom limit it can fit anywhere you wish.
