I have Trex600 and xl motor with HV85 and 611 gyro with gain of 36 .. I have been very pleased with the gov with v1.55. The problem of significant tail twitching and obvious motor surg, started after I loaded v1.56.. Here is the data file that worked well with 1.55 and was not happy with 1.56

I did not get a chance to test 1.56 this weekend. I will try it next weekend.

Do not cut the red wire between the ESC and receiver on any CC HV ESCS. Disabling the red wire only applies to the regular Phoenix ESCS, not the HVS. If you cut the red wire on an HV the ESC will not work. The brown and red wires carry voltage and about 40 mw to power the opto isolators in the ESC.
The latest release of firmware, 1.56' fixes a bug in gov mode. You might have to reset your gov gain with the new software but it is worth it as the governor will work better over a wider range of headspeeds. This means if you are changing headspeed in gov mode you shouldn't have to change gov gain to get the different headspeeds to not tail twitch. The 75% in 'Heli: Fixed Endpoint' is actually a number from last year. The reason for setting this first is make sure your heli is geared correctly. As Finless said if the gov doesn't have headroom it cannot work correctly. Finless did make a slight mistake in the vid as we recommend getting the headspeed you want in gov mode at the 75% throttle setting in 'Heli: Fixed Endpoints' by gearing accordingly. You would then match this headspeed in gov mode where throttle % doesn't really mean anything. Whatever % you get that headspeed on gov mode is OK. My understanding is that Mr. Finless is going to make this change in the coming vid. The reason 75% is now oldschool is as batteries get better the gov needs less headroom to work correctly. With new GOOD batteries the percentage can be increased to 80% - 85%. The better the batteries, meaning the faster they can discharge, the higher the 'Fixed Endpoint' gearing percentage to get your desired headspeed can be. We greatly appreciate the effort Mr. Clintstone and Mr. Finless have put into figuring out how our ESCS work in helicopters and then making this information available. At Castle Creations we feel that because helicopters are complex devices the user should be able to set their ESC up to work correctly with their helicopter and set up instead of only working with specific equipment. The pilot should be able to choose their motor and batteries independent of the demands of the ESC. This makes setting up a CC ESC a little more complex but enables it to work with what you want in a helicopter, not what is dictated by a single component in the helicopter. That it took people like Clint and Bob to figure it out is not a problem. That they are so willing to contact us, figure it out then share the info in a way anyone can do a good set up with their stuff is more than great! We thank them for it. -- Bernie Wolfard |

Thanks Bernie!!!!
Really good seeing you guys here supporting users I am right at this moment compressing the updated vids I shot this weekend. I think they will correct the current videos by clarifying how to set up the head speed in gov. Anyway the new vids going up tonight should help clear things up (I hope). Again thanks Bernie for stepping in and helping users... It's AWESOME to see support like this by a manufacturer on a forum! :mrgreen: Bob

OK I updated Part 1 and Part 2 and I also added a flight test to show how the gov works... I am NO hot 3D pilot but I think the flight test shows how well this gov works!
Anyway I hope this clears up using the gov mode? Let me know what you all think. Bob

Great job, Bob..
I kindof figured all this out over several months, but your new videos should make quantum leaps in everyones learning curve.. Thanks, Sandy |

Thanks for the updates. That makes perfect sense to me now.
I have an idea on programming your DX7 and the whole throttle hold / throttle cut deal. I forget the exact term (my TX is at home), but can't you program mixes between channels on the DX7? Could you program the mode switch to add throttle? Code:
Mode Throttle Setting Programed Throttle Add Notes ---------------------------------------------------------------------------------------- Normal 67% Flat (gov) 0 1860HS, throttle hold = 0% Idle 1(2) 67% Flat (gov) + 5 1960HS, throttle hold = 5% Both Normal and Idle Up modes would all be at your low gov setting, and you add additional throttle with programming mix to get the increase HS you want for each flight mode. Hope that makes sense! Jason (edited to fix format of table above) |

Just to share, heres what i have found out for my setup(z30a-1110kv, cc85hv,6s packs, gy401+9254). I have tried v1.55 and v1.56 both with same gain settings (20) ,however, i find that the v1.56 still gives me the pulsating throttle. The pulsating throttle is not as hard as before, but its becoming more frequent on v1.56. I noticed my tail can't hold as well as compared with v1.55.
Heres how i would sum up the differences - V1.55 compensates more with each change to hs but its frequency is lesser. V1.56 is vice versa, compensates less but gov cuts in more often, resulting in a tail thats not able to hold. Personally i prefer v1.55 with my kind of setup and i feel the gov bugs are not completely eliminated. *Note that frenqency refers to how often the gov cuts in to compensate for drop in hs. Appreciate if you guys can share your findings too. |

I have Trex600 and xl motor with HV85 and 611 gyro with gain of 36..
I got a chance to work with v1.56 and found the tail is still twitchy, but it improved the further down I went.. I stopped at 7 (v1.55 was happy at 20) and twitch is slightly noticable.. I added throttle response to 3 without any change.. How low do I go? Back to v1.55? |

FYI, Bernie from Castle told me 3.0 is going to be out if not already. He asked me to try it and I will do so this weekend.
He said there are HUGE changes and fixes for GOV mode. He also said it wont change your settings but the gov mode values will be very different than 1.55 and 1.56 so I assume that means we will need to play with gain again. Bob

Just to share, heres what patrick from cc reviews on the v1.56 and v 1.55..quoted from RCG.
"We found that earlier version were actually applying gains incorrectly on one side of the setpoint, so what was happening was that gains were stronger if the RPM was below the setpoint, and weaker if RPM was above the setpoint. This prompted many users to use a higher gain than was required, and also caused more oscillations. In 1.56 we fixed the gain application, so that gains were correctly applied. This will mean that most setups will require less gain than on previous versions to get a good RPM hold. But from the reports I've seen, it seems we may have to lower the integral gain across the board to get rid of the oscillations. Patrick " So chances are with v1.56 your gain has to be much lower compared with v1.55. |

With v 1.56, I have taken gov gain down to 3 and finally got rid of the twitches and holds the rpms on the elogger. So, at least for the trex600, XL motor, 611 and HV85 the very low gov gain figure works fine..

Can anyone advise if its ok for gov gain to go as low as 3 like sandy's setup? Is gov gain at 3 going to be as good as a setup with 60 gain, will performance be the same?
Thanks in advance. |

Wow... The wires to this thing are like telephone poles!
What kind of bullet connectors are you guys soldering on, and how do you get them to fit? So far I have just soldered stock Align wires and bullets... Everything fits. |

I used the bullets from Align for the 600. They just BARELY fit the wires.

Thanks... I'll try that.
Edited... Tried it... OK, Ill just have to bow to the master on this one. Getting those suckas to fit the Align bullets is just beyond my soldering expertise (lack of). I did have one large NEU fitting that fit like a glove. I'll just have to order two more, and use those. THANKS! |
