Electric Stunt > ESC Settings
Castle Edge 50
Paul Taylor:
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.
Paul Taylor:
Just bumped the RPM up to 11,534
RPM did not change
9240 ????
John Paris:
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
