720be Governor + YGE 160HV setup issues...
So I spent a bunch of time trying to get the governor setup with my YGE 160HV.
This is on a Logo 700 which has a 175 tooth main gear and a 17 tooth pinion. I basically follow the setup step described here exactly as the starting point. https://www.helifreak.com/showthread.php?t=544882 I setup the governor via the wizard with the following settings shown in the first image. My throttle curve is 0-40-40-40-40 in normal. 60-60-60-60-60 in IU1, and 100-100-100-100-100 in IU2. I then did a bench spool up with no blades. You can see the log in the 2nd image. I started in normal mode and as soon as I hit 40% you can see the rpm jump up to 2700. I sit in normal for 10s, then switch to IU1. No change in RPM. Then switch to IU2. No change in rpm. Then back to IU1; no change, and finally spool down in normal. Clearly the governor isn't really doing anything. The headspeed is WAY over what I specified, if the reported RPM is even correct at all.. Pulling my hair out on this one and hoping someone can offer any advice... |

=] the gov gain is way too high, the RPM1 is set too low, it needs blades on for a more accurate account of logging...

I set the rpm super low in the hopes of going into IU I'd at least hear a change in the motor speed, but got nothing. :/ Lastly, the steps in the procedure I linked clearly indicate that bench testing with no blades should and did work fine for him... Quote:

Ok, Gov gain at 30
Check manage collective. Take it your using the short lead, plugged into a phase lead that you made? Have you calibrated the yge throttle low and high? 1st, make sure your radio is 0 25 50 75 100. Then set low and high throttle as per instructions in skookum software and check in live data you have 0 through to 100. now plug the packs in ( both ) with the throttle stick up, ( no blades ) listen for confirmation, then pull stick down, again listen for confirmation, now un plug. That's the yge throttle end points done. Now you need to do your prog card settings, Start up speed heli middle. Select active free wheel, gov off press enter 3 times. Now go back and select start up speed plane fast, enter. Any more problems then please just ask. I have 2 Helis on yge with skookum gov and have always worked perfecty, in fact there so much better than the Kontronik govs.

Also, a true test needs blades.

Yes. It flies great with normal curves. I should note that I've never flown a governor before; in about 6 attempts, I've never gotten one to setup properly... (2 YGEs, & a Castle) :/ Check. Quote:

Sadly, on mine I had to use a separate Hobbywing phase sensor. It never ran right otherwise. Problem solved and my Yge 160Hv with sink works like a charm with the Sk gov. Brilliant actually.

Very odd. Something's not right somewhere. I will get a video of mine spooling up and holding Rpm in tic tocs. I was demonstrating the difference between 2 helis yesterday
1 7hv with yge 160- ultimate motor and sk gov 1 X7 with helijive ultimate motor and jive gov Exact same ham fisted tic tocs with the jive gov bogging and sk gov powering on through. Can you post all your settings on the yge prog card please?

Here ya go..
FWIW, no matter how many times I set Act. Freew. Gov. Mode to Gov. off, after a power cycle and just looking at the settings, it ALWAYS shows as the picture below with it set to Gov. Store. |

I finally got the Gov. Off to stick.
No better results. I've been screwing around with this for probably 6 hours now. Similar problems I have with all governors. This is 3 seperate YGE ESC's on 3 differnt FBL's (2 720be's, and 1 V-Bar) that have had zero success. I guess it's back to curves once again.. Attempt 7 in the books. |

Ok. From looking at the pics something's nit right. There should be 2 LEDs visable for each line on the prog card.
Also, are you getting a confirmation beep each time you press enter? Can you also tell me how you have it plugged in? And powered.

Good catch!
Can I ask a question? Are you using a separate RX with this? If the prog card isn't coupled in correctly it won't program the esc. I had to run a separate power lead into my card that wasn't powered by the on board bec or RX. Why? Because the card wasn't initializing in sync with the esc. I fought this for days. Now I have a separate power system to power the card before the esc initializes. Also, With the gov off on the esc. Now check through the Skookum setup screen to see if the Sk is seeing the rpm phasing signal when you spin the motor by hand with the system powered up. Hit the view tab. Scroll down 6 until you hit display voltage and rpm data. You should see the rpm dot light up blue as it reads the motor output signal as the motor turns. If not, your Yge isn't sending out the signal or it is not wired in correctly? Mine never did turn out the signal so I just installed the cheap and easy HW sensor. Either way, you can get this working! Hang in there. It is sooo worth it. Heathy knows this system better than just about anyone! I am certain he has the ability to get you sorted out here.

Sure is Randy. Might be worth double checking the phase lead you made is correct too. Also is this yge 160 at least less than a year old?

The ESC? The main throttle connection connects to the IO-A(T) input on the Powerbus. The shorter programmer lead is connected to the programming card when using that, or into the IO-C port on the 720BE via the phase sensor cable I made as described here: https://www.helifreak.com/attachment...0&d=1316003857 When using the programming card, I have the RX connector on the card plugged into an unused port of my Futaba R6203SB receiver and the other port plugged into the the short lead on the 160HV. |

BINGO! The futaba Rx may be the culprit here! There is an initialization time delay from the RX here that allows the esc to initialize before the card does! I had this same issue. You need to bypass the Futaba RX power connection with another alternative. By the time the esc sees the card programming, it is already locked out due to the card not powering up in time. The RX power up signal delay is the cause! I wrote about this in the Yge section about a year and a half ago when guys were having problems. It also happens with some Spektrum Rx's also. Also, as Heathy asked, is this Yge less than a year old?

As an aside, Im using the PowerBus with the switch conencted to a 2s LiPo, so I power that on (everything except the ESC gets power) before i connect the ESC to the flight battery. This seems to allow me to enter programming mode successfully. I'll try your option anyway, but I suspect what I'm doing circumvents the "Slow boot up" issue you describe. It's a YEP card (HK) that's about 3 months old. |

720be Governor + YGE 160HV setup issues...
What prog card is it? The 2 needs power from a enloop or 4.8v nicad. The 3 can take HV.

You will need to plug the short 4" lead ( without phase lead plugged in ) into the left plug on prog card. Orange wire on left
Now throttle lead ( long one ) disconnected from power bus / sk. Now take the extension lead ( servo plug both ends ) and plug into right port on prog card and throttle port on sk. Now, if using prog card 2 you power it through a spare port on sk so un plug your bec or 2s lipo. And go there Power on tx, then plug both batteries in, now prog card should come alive, now you go through prog options.
