Got some more answers from Frank. Might look a bit confusing if one dont have the manual and the esc.
-----------------------------------------------------
Have been flying some more with it in the Joker2 with Actro motor now, and agree that the governor function works quite good, might even be good enough for me :-). But still I would like to have the option for making a manual throttle curve, maybe that's just me, and maybe one can say that this is not required if the governor is working good or maybe even better than a manual throttle curve.
1. Ok, I think the slow start with the SPC jumper only in place is very good already, have five jumper positions, but only four is named, and like this: EMK, REV, MOD and SPC the last jumper position is unnamed so I don't have a SLS jumper position unless it is the unnamed position? Can you confirm that the slow start will be even slower if both the SPC and the unnamed jumper position which might be the SLS position is mounted with a jumper?
A.
Because you have a prototype the label of the controller is not up to date but i think the software is. Try setting the unnamed which is the SLS jumper.
2. I made a mistake when I wrote 2 pole NEU motor, it is a 4 pole motor. From your manual I cant find out what the rpm limit is for a 4 poled NEU motor in SPC mode, Maybe you can explain how these limits works.
A.
The speed stated in our manual is caculated for actro motors which do have 8 poles. So you can reach double speed compared to them, meaning max. approx. 60000rpm when jumper REV is set.
3. In the manual the max speed for a 2 pole motor is 154.000 rpm. So is it 154.000 rpm or 70.000 rpm there is valid for a 2 pole motor with SPC jumper in place?
A.
yes
4. What it the rpm limit for a 4 pole NEU motor in SPC mode or with the controlpanel V3 attached?
A.
See above, approx. 6000rpm
5. What is the rpm limit with this controller and my Actro 32-3 heli Motor? in the manual page 20 the max. speed actro is 38500 rpm, but on page 14 it is 30600 rpm in SPC mode. Maybe the 38500 rpm is in REV mode? Further down on page15 maximum speed without controlpanel V3 is written to be fixed to 17500 rpm? I am confused....what is max. rpm with and without control panel V3, and with softstart eg. SPC jumper installed ?
A.
The max. speed o the controller can handle is 38500rpm. But this is limited in speed control mode because the speed contrller needs some overhead and also consumes some calculation power.
With jumper SPC max. speed is set to 17500rpm without jumper REV, with jumper REV it is 30600rpm. When using Controlpanel speed limit can be set within 2500..17500rpm (with jumper REV 4400..30600rpm) using a potentiometer.
6. You mentioned that REV jumper will raise the max rpm. guess that is only intended for being used with cars and boats as you cant fly a heli in this mode.
A.
The original intention is to set the same speed range using 14pol motors like our actro C or actro CL. But as a positive side effect 8pole-actro motors can be driven with higher speeds like in very high power helis (reported to be up to 25000 rpm..).
7. My akku wiring is made as short as possible, and below the recommended 30 cm.
A.
That is very good. This helps cutting over voltage porblems and optimises efficiency.
8. Know that startup is not impossible without slow start, but with a 4 poled NEU motor it is unrealistic as the gears will be destroyed quickly even that one is very careful, so not really an option for me. Therefore I assume that SPC mode is the only available mode for heli´s if one want softstart.
A.
Yes i think so.
9. Cant find any information on the controlpanel V3 in the manual, found it on your webpage, but still cant see what difference it will make except for the flashing light when the battery is empty, Can you explain what extra features I will have if I buy this unit?
A.
You can set the speed controller gains (proportional and integral) to you exact needs as well as the max. speed at 100% throttle you like to use. So you can adopt the behaviour of the speed controller to your needs. Controller gain with SPC is set to a comparatively high level used in high power helis.

The controller works exactly as designed I think, no problems so far, starts everytime, good softstart and good governor.
But the main interest for me is if it can give me max power in my heli´s with both the actro and the NEU motor, and I am still in doubt about that.
It all depends on this REV mode as I see it, With the REV jumper installed the controller is in car mode.
17500 rpm 8 pole / 35.000 rpm 4 pole is not enough. With a 1:11 gearing in the Joker, this is just enough for good performance, but not good enough for a power setup. 35.000 rpm with a NEU motor is not good enough if one is looking for 47.000 rpm.
So for a power setup there is only one option, and that is to get this controller working with the REV jumper installed to reach 30.000 rpm 8 pole / 60.000 rpm 4 pole, not sure if it is possible to make a good working setup with REV (car mode) activated in a heli, maybe / maybe not.
This is what is written in the manual about REV (car mode):
---
If installed, the motor can be run in both directions. The motor stops in the middle of the throttle, if throttle is turned forward it runs normal, backwards means revers rotation. Be aware that upon activation of the actronic the normal mode is scaled to 100% to speed. By differentiating the backward section of throttle you may set a limit on the speed in reverse direction.
If constant speed mode is activated, this jumper changes the speed range. This is to adapt ot set the same range (2500..17500rpm) for actro-C/actro-CL up to 30600rpm for normal actro.
