I am looking for standard setting for the Castle ESC.
Looking at the Cookbook is shows in Fig 2 that Throttle Type is Governor Mode. And the mode is set to Governor High.
The Desired Head Speed is
1. 9469
2. 9562
3. 9657
If I understand this correctly the Desired Head Speed is what the ESC will use as a base line to governor the motor.
I am trying to set the RPM to a desired setting in the FM 9 timer. I am not sure if the setting match what the plane is actually flying at. I will put a tach on it as I proceed. But I am thinking maybe the ESC is fighting with the Timer???
Am I out in left field again?
Can someone please post there file they are using with a FM9 timer on a large Stunter?
Thanks

Paul, I know what you are talking about and I am not sure there is a fix. Hopefully others have one. I used the Castle 50 and FM-9 on a relatively light plane (fancherized Twister) with great success but when I transferred the same setup to a full size ship I could not ever the the boost right. I am now using the Fiorotti. My symptom was that the boost only restored the preset RPM which was at times insufficient to adequately restore the momentum lost in a turn and it would start to pulsate. It would recover on long periods of high drain like the hourglass and overheads but not on the shorter legs like squares and triangles. It was never so bad that I couldn't fly it, affecting locking mostly, and I got used to it finally but never liked it. There may be a setting that would have cured this and perhaps fiddling with RPM and prop pitch may have circumvented it, but I will never know since I lost all of my Castle ESCs in a fire.
Good luck - Ken

Wow, sorry to hear about your fire loss. I hope is was not due to batteries.
I just put a tach on it. (We are in the outer bands of Hurricane Debby so playing in the shop.)
FM9 settings
Phoenix High
RPM 11,356
Actual RPM with Tach = 9240
Will try again adjusting the RPM.
-
Just bumped the RPM up to 11,534
RPM did not change
9240 ????

Paul,
I trust that you have the kV for your motor set right in the settings for the motor and have enough volts to spin at the speed you are looking for. Setting the battery on the throttle page will help see if you are in the right range.I normally run mine around 10K rpm in relatively light planes, but have run this set up in a 70 ounce SV without issue as well (although it has been a while). Normally I use the Set RPM mode and preset my ESC to the speed I desire in #2 a little slower in #1 and a little faster in #3 until I am more familiar with what is needed. On the FM-9 I use Phoenix set RPM and choose #2 and do a quick hop to see if it is what I am looking for and add or subtract as needed. Cannot say as I have ever gone back and tached the prop but the RPM has been inline with the setting on the ESC that the FM-9 has selected according to the info downloaded from the ESC.
Will be curious to learn what you find out. FWIW, I think that there was some discussion on SH from Mike Alimov regarding the throttle RPM in the Phoenix ICE/EDGE not matching up well with what was actually put out. Do not recall the outcome of that discussion since I generally use the Set RPM settings.
Regards,
John

So you don’t use the settings in the cookbook. Governor mode?
Anyway you can save off the config and email it?
Or screenshots?
I’m almost at the point of thinking of swapping for a BA or Cobra ESC.
-
Paul,
Guess I was not aware of these cookbook settings. Not good at following instructions... Just been using the information I sent in the last post. Will see if I can get some time to put together what you are looking for. Will take some shots of the FM-9 programmer as well.

Thanks for the feed back.
That is probably what I did wrong. I was going by the book. 🤓
I was going by the Cookbook.
I have the program box.
I think that cookbook needs revisions by someone that knows more than me.

Good info Thanks
So for desired head speeds?
Blank?
-
Yes, blank head speeds.
-
Yes, blank head speeds.
Ok will test it. Thanks Brent.
-
Head speeds don't do anything in Governor mode.

I tried to remove the head speed (leave it blank) it kept setting it to a number that it did not like.
Here is where I’m at.
Will do a test and tach it tomorrow.

This is my Castle ESC .DAT file if you want to download it.
Upload it into your CastleLink software and see if it loads.

Thanks a bunch Brent. I’ll give it a try in a few and report back. 👍🏼
-
Ok gave it a try. Seems a little better. The only change I see is the Head Speed Change Rate.
I’m not sure what effect that has.
After running a few tests the RPMs did change but some strange things happened and has happened. Let me explain.
Using the timer program box:
I set the rpm as low as it would allow. 8430.
The motor was tach’ed at about 7k
I’m assuming the box is in need of an update.
Set rpm to 10524 - tach’ed 9300
Set rpm to 10728 - I shut it down when it hit 15k on the tach. I could have been in 3 blade setting by mistake. I just did not want to chance it.
Set rpm to 10592 - tach’ed 9340
Set rpm to 10660 - tached 9360
So now I go back into the ESC to review the settings and now the desired head speeds all have negative numbers. Will post a screenshot below this post via taptalk.
I did also notice that the start up beeps have changed to just 1 beep the two beeps.

Desired head speeds went from blank to negative numbers. ???

Is it possible that the number of magnets is set wrong someplace? The difference is roughly the difference between 12 and 14 polls. Just a brain storming shot in the dark. Hope you get it right. On mine I never paid much attention to what the TAC said. I just flew it till I had it where I wanted then recorded what the box said and used that as a baseline.

Thanks Ken
It’s set to 14.
Cobra 3520/12 manual says 14 poles.
I’m curious as to why it took the liberty to put negative numbers in the desired head speeds.
Castle are high dollar ESC with too many variables.
-
The negative headspeed numbers are no worries.
Did you adjust the motor info to the Cobra 3520/12 motor's 820kv?
If you are running a 4s system, it should generally be set at 14.8v, and 5s would be 18.5v.

Yea I changed the KV and the voltage is the same.
Are the number of beeps the same as your getting? I know it supposed to play a happy tune and tell you how many batteries it sees. 🤓
-

Agreed, that in part is why I switched to the Jeti Spin Pro. Just as high dollar, maybe more but simple to set up. The nice thing about active timers is that they replace most of the things the high end ESC's do. Lots of R&D going on there. I expect my Fiorotti to be obsolete soon.

The Climb/Dive timer is quite easy to set up via bluetooth on your phone, and uses cheapo ESC's.

Yea I’m leaning that way.
I just did another test.
Set the rpm to 10796 - it did tach at over 16k !!!
It also shuttered at ramp up start, not like on the initial push of the button. Never experienced that before.
Something is definitely wrong. Maybe a bad FM9?
-
PROBLEM SOLVED!!!!!
Just for giggles and grins I decided to scroll through the different modes of ESC. There are a few for Phoenix. The some other brands. And then up pops Phoenix NEW high. I read it in the manual Phoenix HIGH and thought that was the setting in the manual.
When scrolling through the list of ESC’s, the NEW high is not listed close to the other Phoenix modes.
It is now working as I would expect it when changing rpms.
Thanks everyone for jumping in and pushing me to think. I like it when I learn something.
I’m living proof you can teach an old dog a new trick. 🐶

John's recollection is quite correct, and even though this specific issue was solved, I will summarize it for the benefit of others who use the Hubin FM-9 timer.
In summary, when a Castle Talon ESC is being programmed in the Phoenix New High mode, there will be a discrepancy in set RPM vs actual RPM. In order to get the actual RPM out of Talon, the FM-9 programmer needs to be set to the Castle Talon mode. If your programmer doesn't have that mode available, thatmeans it is an older version. It can be updated by ordering a new chip from Will Hubin, replacing the old chip in the programmer box.
-
Well I guess I had the old chip. I couldn’t get the desired Rpm / lap times using the Castle- FM 9 setup.
When going with set rpm settings it really drained the battery.
So maybe I created the battery issue using the set rpm settings.
My fix was a BA ESC and a C&D timer.
But still need a little more battery because the C&D does a speed up at the end. I think I can disable it but I like it to setup the landing. 👍🏼

What batteries are you using? I have found that Li-Ion can stand abuse far greater then Lipo. I regularly use 90% of the mah and keep them charged for days at a time. The ones I am using now are approaching 100 cycles on some and there are no signs of problems. My point - keep the full power at the end. Landings are so much better. If you are already using Li-Ion - Never mind.
If the battery police are listening in, I didn't write this, I was hacked. ~^
