The vBar governor for electrics is coming out on 2/16. The ESC needs a mode to change the throttle output as quickly as possible in airplane mode. But it seems there is a delay with Castle esc's.

Can this be fixed in a future firmware patch?

I spoke with Ralph yesterday here in Nuremberg & will be bringing info of this back to our engineers so...............

Awesome, thanks!

Here is more info from Frederick (MrMel) who is currently doing the governor beta testing:

"Yes, here is how it works;
It's not that it does not work at all, it just that you get better performance with other brands that has no delay, even at 10 Castle has a "expo curve" on the throttle response, which others do not have.
The problem is also that if you put the VBar into more aggressive mode (higher gain) the Castle will stutter the motor since it's not ready with it's change when next command comes in."

Ah good, i have tried to contact patrick without success, feel free to contact me if you need detailed info.

Made a video to show the difference

Speedcontrollers different throttle response. (2 min 7 sec)

(unlisted so you need the link)

I hope they are able to give us an update to fix this. I just installed CC ice esc's on all of my vbar'd birds and more.

Patrick showed up here with us so we will be discussing it.
One of us probably will be contacting.

You'd think they would have discovered this with the TotalG eGov development.

I'd like to hear an ETA once they have a chance to look at the issue.

The TG ATG does not need the Castle ESC delay to be fixed. I have been running this setup for a year and it works fine.

Removing the delay would be nice though, for even better performance.

Exactly what is the problem?

I have been using CC ESC’s for many years with a couple of eMultiGov governors. They have all worked perfectly and have very tight headspeed control.

What about the new Futaba CGY750 with governor? I have one on the way and was planning on using it with my ICE 100.


?

To clarify the issue:

• Testing is being done with the vBar gov and several brands of ESC's
• Within this testing, it was found that a much lower gain must be used with Castle ESC's vs some some others. Higher gains would cause oscillations. Lower gains limit how well the headspeed can be regulated
• The root cause appears to be something like "expo" on the throttle output when in airplane mode with a max (10) throttle change rate. As seen in the above video

So it's not that it won't work. It's just that it doesn't work nearly as well as other ESC's that have a nearly instant throttle response. So as it stands now, if you want to use the vbar gov, a Castle ESC is not the best choice.

It's clearly to Castle's advantage making their ESC's the premier performer with the vbar governor. It becomes much harder to justify the super high end ESC's as the performance has been touted as better then anything else currently on the market.

Here's the marketing:

Governor
(not yet for Mini)

The V5.1 PRO contains a new developed governor function. Its not a separate unit, but communicates with all other internal algorithms to get the best possible results. This gives a performance, that currently is not known from governors. The governor for Mini VBar will be made available at a later point in time.


Extremly fast and precise headspeed control. Maximum power can be unleashed by taking the limits of the throttle into account.

Extra stiff headspeed, no lag if you apply load quickly.


Works with a preview of the needed power, which is possible because of watching the complete system.

Instant power, regardless what you do.


Very flexible, we have a solution for most configurations.

One Channel, or two, throttle curves internal or from Tx, just as you like it.


Usable for Nitro and Electric helis. Special modes take care of the different characeristics of the power systems.

Really good governing now available for nitros too


Softstart and autorotaion bailout, collective management to avoid motor overloading and much more.

Everything included, but really simple wiring.

V5.1 PRO defines a new reference. The type of integration is completely new and results in an exceptionally stiff headspeed at nitros or electrics, without the artefacts of an aggressive governor.

I just purchased the Castle Ice 100 and Hyperion Phase sensor in anticipation of the latest V-Bar 5.1 software. I really hope CC provides a firmware update to remove the delay.

Kontronik ESCs seem to have issues with the vBar gov as well:

Can someone remind me why we need flybarless?

Another interesting tidbit.

If you're in fixed endpoint mode and set the head speed change rate to max (20) there is a 2 second delay on throttle changes! So the average guy using v curves gets really bad performance.

This has me wondering. Does the Castle gov get sent through the same throttle filter as airplane mode? This would really hinder performance.

Here's the marketing:

Looks like CC will have to make an “External Governor” throttle mode option. Sounds like the same problem that the multi-rotor guys are having. For them the $15 Chinese ESC’s perform better than the $60 CC ESC’s.
