Need GV1 governor help badly

[Mike SVOR]

Yes, I know.

It says Zero.

I can spool it up, click the idle up 1 position, rpms go through the roof, quickly click it back to normal, spool down, kill motor using kill switch on transmitter (switch H), scroll the gov menu to Max and it says 0 (zero).

I have repositioned the sensor and it didn't change anything.
It reads idle or current rpm while I'm watching it idle and while i'm starting it.

Max doesn't record for some reason.

Can you hover well enough to read the rpm screen with the canopy off?
Just asking.

I would suggest taking the canopy off and hover the model and read the rpm on the GV1 screen. Then click into idle 1 for 10 or 15 seconds and read the rpm screen. I have done this before and it is not difficult to do. It helps more if you have someone that can help you look at the RPM screen while hovering. I can read the screen at 15-20 feet distance usually.

I would suggest to get the model flying in idle ups without the GV1 being on. It could be you have a tuning issue on the motor. Only way to check that is to setup some throttle curves and fly the model with the GV1 off.

either the head or the blades are going to explode if I leave it in idle up 1 for more than 3 seconds.
I darn sure ain't gona get anywhere near that thing when clicking the switch to idle up 1 either.
It is fairly difficult to hover when the engine is accelerating like that. The tail is torquing over, head speed is ripping up, changing pitch as it accelerates rpm....
I don't think it's good for it at that high rpm.

I even tried lowering the gear ratio on the screen to 3:1. No change. it still goes ballistic.

This is/was a perfect running heli. I'm on my 6th gallon of fuel. The motor is tuned perfect.
I had all my curves set up perfect the way I like them until I put this governor on.
If I turn the gov off and set it all back to how it was, it kinda defeats the purpose of buying it. :D

I really think its broken.

damn, another week down the drain.....



I really do appreciate your help through this. Thanks man.

And your reason for putting on the governor was what?

I have not used a governor in over 5 years now.

durring forward flight and then doing a forward flip (or backwards flip) while maintaining forward flight, when pushing negative to keep momentum going on the forward travel, the head speed goes up.
This is different that the loading required to just hover inverted.

Also, I wanted the luxury of changing tunes without having to reset all my throttle curves every time I richen or lean the motor.

It was something I wanted.

[DavidH]

You should set the throttle curves when the motor is tuned properly.
So why would you have to change the curves when the motor is richened or leaned? Why would you be changing the mixture if is perfect?

David

[Mike SVOR]

getting a little off topic, but I guess I'm gona have to send this governor back anyways.

I did, It was, and it still is.

So why would you have to change the curves when the motor is richened or leaned?

If I go and lean it out 3 clicks, I have to lower the percentages across the throttle curves. The rpms go up.

Why would you be changing the mixture if is perfect?

If it's a hot day and I want to fog some mosquitos out, I'll richen it up a few clicks every now and then.

Quick question.....Did you set the Throttle Limit Settings? Governor Idle/High/Stop points?

[Mike SVOR]

Quick question.....Did you set the Throttle Limit Settings? Governor Idle/High/Stop points?

Yep, about 15 times.

[wren1702]

One more quick thought, did you install 1 magnet or 2? If 2 is one installed opposite pole from the other?

[Mike SVOR]

What does this mean (taken from the GV-1 manual):

MAX speed display - This function displays maximum engine speed or rotor speed. It can be used to check engine power. However, the maximum speed when the throttle stick is 95% or more from the high side is memorized.




'maximum speed is memorized when the throttle stick is 95% from the high side'????? What in the world does that mean? does that mean it memorizes everything from 5% throttle up or only memorizes rpm when 95% full stick is given?

[Mike SVOR]

installed two.

only get a reading once every revolution. they're in there correctly.

[Mike SVOR]

Got it to work for a second.... then it ran out of gas (i only filled up the header tank), and now it's dark out.

I set it up so that it's turned on by the collective stick at ~20% in normal AND I set the normal rpm to be 1100. I set the idle up 1 to be at 1100 also. (just for testing).
It seemed to hold the rpms.

Is there an issue with having it off in normal then having it on in idle up 1?
Are the throttle curves throwing it off?
Again, they are:
Normal: 0, 25, 50, 75, 100
Idle up 1: 100, 70, 40, 70, 100
Idle up 2: 100, 70, 40, 70, 100

I have no idea as to the reasoning behind this programming.
Does it need a flat throttle curve when it's turned on? Say if I program the idle up 1 to be a flat curve as 0, 25, 50, 75, 100... will it work fine then?
God only knows..... ugg.

It still didn't get a max rpm. Is this because I didn't give it full positive pitch?
I can't understand that manual at all. I'm a course designer/author and that manual turns my stomach to read it.

[wren1702]

This may be a silly question, but why such a low RPM on the head? I wouldn't go lower than 1600 in normal mode, 1850 in Idle 1 and 1950 in Idle 2. Your motor will be much happier.

Your throttle curves are just fine, you need the set like you have them so that if you have a gov. failure you can still fly fairly normal.

[Mike SVOR]

I like it that low for landing/taking-off. It softens up the collective a ton so the heli isn't bouncing all over the ground from the slightest movement of the collective stick.
It's not a setting for power, it's a setting for smoothness.

As shown by my previous throttle curves in Idle up 2 were: 100, 80, 55, 80, 100
It sounded like it was reving good on that curve. So I'll have to see where the rpms pan-out once/if this thing records max rpm tomorrow.

[wren1702]

Good luck with it, this kind of stuff can drive me crazy! That's why I fly all electric now! :smokin: :YeaBaby:

Personally, I wouldn't fly a nitro heli without a Governor.

Well I went out to do my first test and I couldnt get the GV1 to come on. I am not using the ON/OFF MIX line and in my video I said to set that to ON as the manual leads you to believe that is the way it needs to be set if not hooked up. Well it didnt work. I had to set it to OFF and then the gov started working.

I will correct my video to state that.

Bob

[Mike SVOR]

Thanks Bob,
Here is the latest seting that I recorded.
It records MAX rpm when given full positive collective, but still won't regulate the rpms at all.

[Mike SVOR]

I just tried both On and Off for that function and still nothing.

[Mike SVOR]

Just got off the phone with Futaba help line. They have instucted me to send it to them for repair/replacement.

That kinda blows. Ya order a part, that is broken, from a store, and you have to instantly send it into another place to have it fixed because it didn't work at all from the beginning.
What kinda nonsense is that?

Anyone wana buy a brand new governor? I'll sell it to you for full price, but as soon as you get it, waste a week trying to make it work, then send it in to Futaba for it to be repaired.
Sound good? Let me know. Paypal me and I'll ship it right out.
LOL (more like: crying out loud)

[Mike SVOR]

Futaba sent me a brand new GV-1 governor and I installed it finally.
This one I think is working. I hope.

Before, when I turned on the old one, it always defaulted to the throttle high/low setup screen, even though I set it many times.
The new one, now that I set the high/low/off screen, now defaults to the rpm screen when turned on. So I guess that is how it was supposed to work?
I'll find out maybe tonight if it works.

Mine always came up on the RPM screen, hope it works OK!

Bob, can you ellaborate on this? I am to inhibit which one?

[Mike SVOR]

ok, I got it.

SWPt = OFF
StSw = ON

It works now.
