I've just spent the last hour reading through old posts concerning the StatorGator and GV1, both of which I just installed my new(bought used/crashed) gasser.
I've never run a govenor before and I am a bit confused about several things but hopefully someone can answer these first few questionsfor me.
1) I think that I may be getting the "cart in front of the horse" by trying to setupthe govenor at this point. I've just finished rebuilding this heli and have not even flown it yet. Do you recommend trimming and flying the bird prior to putting the govenor in service?
2) I've read a bit about the gear ratios, but is that still relevant while using the StatorGator? Seeing as there is no pickup on the fan, but I can understand that the stator rpm would be the same as the fan rpm and therefore rpm still comes into play. Is this correct?
3) does anyone know the gear ratio for theXCell gasser, I believe it is the 1005?

Thanks for your patience. I'm sure that I'll have more questions as I try to set up the GV1.

The Stock Xcell 1005 gasser has a 6.4:1 gear ratio.. Thats a 90 tooth main gear and 14 tooth pinion gear.. Yes you will need this info.. As far a the gov. setup.. I would make sure that your curves are close before putting the gov. into play. buts thats just me,, XGM formally known as John Crotts

Thanks again John,
Thats pretty much the same ratioI came up with, (6:4.3, I rounded up). I didnt think the ratios on these were that high, I was expecting something in the 8:5 range. And yes I think you;re right that it is going tobe better to get the heli dialed in with curves before I bring the govenor into play. I have it mounted and connected and figured out how to set a switch to keep it turned off until it is time to use it.

I have been changing the frames on my Xcell gas, MA made me a new set of lower frames, So I could use the newer clutch stack, and be able to change the ratio's,, I now have 8.45:1 but I can go to 9.3:1 if I need to.. I'm building a AP heli,, with a Broadcast 360 mount.. Got to fly it last week, for the first time, and I'm haveing glitching problems, I think I have it fixed, but today will tell the story..
With the 6.43:1 gear ratio, You will have a pretty high head speed, Before all the changes, 690 blades,I was running a head speed of 1800, normal, 1900 idle up 1 and 2000 in idle up 2,, I know that sounds high, but is sure flew great at that speed,, I think, that got the engine rpm's up to 12,000, or somewhere around that.. But I'm now running MAH's 810 blades with a gear ratio of 8.45:1 with a head speed of about 1550 to 1600,, Hope that is right,, thats what I'm shooting for.. XGM formally known as John Crotts

Install the gv-1 now, you can always turn it off remotely
Print this:

Set the gear ratio to 6.43
On the gv-1:
Plug in the aux on/off into the gear switch
Plug in the aux rpm into the idle up channel, aux 3 probably
Plug in the throttle input into the throttle on rx
Plug in the stator gator into sensor on gv-1
Plug in the throttle servo right below that, be careful not to plug into mixture slot by mistake.
Turn on gv-1
Set idle, full throttle, and kill on gv-1 screen.
Click + on gv-1 until you see speed 1. dial that in to 1500.
Move switch from normal to idle up 1, dial speed 2 to 1620 rpms.
Move switch to idle up 2, dial speed 3 to 1740 rpms.
Go to Stsw screen, enable it (push + to change INH).
Go to SwCD screen (this is you gv-1 monitor). Verify the following:
Throttle up, does Swcd change to ON, then good. If not toggle gear switch, it should change to ON and OFF when you toggle it.
If you don't like the on/off position on the gear switch, go to channel reverse and reverse channel 5 to flip the switch on/off position.
Hit idle up 1, assuming you have full throttle full up and full down for 3d, gv-1 should remain on all the time no matter where you move the throttle stick. Same goes for idle up 2.
In normal mode gv-1 should go off when you throttle back all the way.
Also, at any time gv-1 is on, if you toggle gear switch or hit throttle hold, SwCD should change to OFF.
If you have this, then you are good.
Proceed to B/FS and active it. On the next screen is the B/FS % screen. If you set idle, and full throttle on gv-1 properly as 10th line above, % should change from 0 to 100% as you move the throttle stick up and down. Set % to 20%. This will give you a low power 2 minute warning if your battery is dying. Remember this, very important, when the engine loses power, LAND, check BATTERY not engine needles as gv-1 may have throtttled back on you.

That is about it, Since you can't check the sensor, start the engine and look at the gv-1 display. If the stator gator is working properly you will see rpms changing as the engine is running on the gv-1 screen.

In the beginning turn off the gv-1 with the gear switch (= to not installed) so you get dial in the engine and throttle curves. Once you are happy with that you just flip the gear switch and the gv-1 is in action for you.

Enjoy,

Hey Raja do you know a fix for this?
In normal mode gv-1 should go off when you throttle back all the way.
Also, at any time gv-1 is on, if you toggle gear switch or hit throttle hold, SwCD should change to OFF.
Following your setup info in this post the gov works perfect except in normal mode no matter what I do I can not get the SwCD to show ON.
Idle up 1 and 2 work great. I am using the futaba 9Z

Any help would be appreciated,

Thanks,
Lou

Throttle hold?
Make sure throttle hold is not on. As you throttle up the gv-1 should show on in SWCD function if the gear switch is on, throttle hold is off, and you throttle up past 20%.

Its a function of the gv-1 so if its working in idle up 1 and 2 it should work the same in normal until you throttle back all the way and turn it off. You can do the opposite and make throttling back all the way NOT turn it off (stick switch disabled) but you don't want that as you want throttle hold to disenguage the gv-1 in any mode.

Raja,

With the heli on my bench,
throttle hold off
normal mode
SWCD screen is off and never goes to on

throttle hold off
Idle 1
SWCD screen turns on past 20% throttle

throttle hold off
Idle 2
SWCD screen turns on past 20% throttle

In idle 1 and 2 when SWCD is on and I flip the throttle hold it turns to off just like it should. It just won't turn on in normal mode for some reason.

Lou

Throttle curves?
Do you have your throttle curves set?

Normal operation on the SWCD should be as follows:

Throttle hold off, gear switch on to enable gv-1;

Throttle up past 20%, SWCD shows on. On all the way to full throttle back back down below 20% and it shows off. This is in Normal mode.

In Idle up 1 and 2, SWCD should be ON all the time, from idle all the way to full throttle. This is because your throttle curves should be as follows as an example:

N: 0, 20, 22.5, 27.5, 100%
ID1: 100, 30, 25, 30, 100%
ID2: 100, 32.5, 30, 32.5, 100%

Anytime SWCD shows ON and you enguage the throttle hold, it should go OFF in any mode (N, ID1, and ID2) every with the throttle stick anywhere.

Anytime SWCD shows ON and you turn off the gv-1 with the gear switch it should go OFF in any mode/throttle stick position as well.

STICK Switch should be enabled in order for the gv-1 to turn on and off above and below 20%.

RECHECK your throttle curves and once you have that set and ATV's set for the throttle go back to the GV-1 Limit Idle screen and rememorize idle, full and kill.

Try again and it should work for you.

Everything is working just as you described except in normal mode, The SWCD will not change to on. My throttle curves for normal, idle 1 and idle 2 are set all the same.

Throttle curves should NOT be the same.
Then it had to be something in your particular radio setup, or the way you plugged in the gv-1. Recheck that but the throttle curves should not be all the same, see above.

Thanks Raja,

I changed models in the trans and the gov worked correctly, I went back the the gasser model and ended up resetting the conditions and now it is working There must have been something that was disabling the switch I had set to turn it on when the mod was in normal mode. You need a 4yr of schooling to operate this 9Z.

Thank you for the help.

Lou

Glad to hear it!
And tell me about those radios! Sometimes it takes a few months before you understand why you need to do something in there, or what that feature is actually good for!

I am not using the gear switch, That still works the gyro....I just assigned another switch to turn the gov on and off.
