Vortex + JR DSX9 & Nitro

[WildWake]

Hi all, has anyone set up the Vortex with a JR DSX9 on a Nitro?

I'm using Speccy sats and the vortex Governor & Spartan sensor on my Trex600n,

Are all of the Gov settings/gains done on the DataPod, with no need for a channel from the tx?
As I've just used the Governor mode on my Tx to match the flight modes on my Tx to the flight modes on the Vortex as explained below...
(my Tx is a JR DSX9, But the menu's shown below for the JR X9303 are the same).
Other Tx's are shown here Spartan RC

Question #138 How do I set my transmitter so the flight mode (Normal, Idle1, etc) matches the corresponding mode of the Vortex? Answer

JR X9303 (as proposed by Bob O @ HeliFreak)The X9303 does not offer individual gyro gain value for four different flight modes. Instead we can use the governor function to control the active flight mode of the Vortex.Hold the ENT button down whist powering on the radio. In the menu locate "DeviceSEL" and open it. Under GEAR change the OUT: option to GOV as shown in the photo. Exit the Setup menu and enter the Function List by pressing the LIST button. From there select the Governor option. Set the percentage value for each flight mode as show in the photo.In the DataPod Home Screen or Setup::Transmitter menu confirm that the Vortex is tracking the radio flight mode correctly. This method has been confirmed to work using satellite receivers. When using a standard receiver with individual channel connections the percentages may need to be slightly altered.

To check that the flight modes were matched I did the following test...
I set the high end of my throttle curves (IN100 OUT100) to the following,
Norm ~ 50%
ST1 ~ 75%
ST2 ~ 100%
Hold ~ -5% with a delay of 2.0 seconds
Then on the DataPod I went to the transmitter live screen, with the throttle stick full up (100%) I clicked through the idle up's and hold, the throttle bar on the DataPod was reading what I'd set modes too in the TX.
When I hit hold in ST2 the throttle bar dropped quickly down 0%, then when I released hold the bar moved smoothly back to 100% due to the 2 sec delay.

So back to the Governor, is it all set in the Vortex via DataPod & the same with the Gyro???

Cheers Guys
(I Think Wavey Davey may have mentioned the DataPod)

Yes. Hook up the datapod and goto the governor section and select headspeed. You will see that the values cycle H,N,1,2. This means, if you can select them you can have 4 different headspeeds. This applies to the gyro as well, you can have 4 different gain values. Basically at any menu item if you see H, N, 1 or 2 in the corner of the screen it is a parameter that is set per the mode you are in.

I thought that was how it was set, BUT just wanted to make sure as it is the Governor, didn't fancy a screaming nitro on the bench in the morning

It works so well Tye, the only thing I've done is increase the ramp up time to 5s, lift your midpoint in your curve to 80 too, so 100,inh,80,inh,100. Set your headspeed and forget

Dave do I do all of this Via the DataPod? you did't mention it?

Dave & Andy Thanks for you Help...

[waveydavey]

Yes apart from your throttle curve Tye, that needs doing in your TX. The headspeed is indeed done in the governor menu in the Datapod for all flight modes N,ST1,ST2,H

Just a few little bits to sort now
I'm Looking forward to tomorrow, will be at the field bright and early...

All sorted, up and running Governor all ok now. When 1st started to set up I had the issue with the DSMX sats and my JR9 (DSM2) tx, I think this may have messed up my attention to the rest of the set up, cuz some how,, I don't know what I did but I must have altered a setting else where.
Any way since then Bob O has posted his Great set up vids, I have watched these a few times & read though the set up guide.
So this morning I did a model rest in my tx & factory reset on the vortex.
Then I followed the video instruction as well as reading the set up guide. Got to the field guv was running sweet as a nut. I'm still a novice and a bit nervous with the 600 nitro so I asked John Watts (my dad,,, well he tells me off like I was his son) to give test flights, he then told me what was happening in flight and u was adjusting the DataPod to suit.
I have a little tail wag at low head speed, but when in st1 & 2 this goes and also when you give big neg pitch the stop it sharply the heli bounces, this could be down to worn dampers. As I have not changed then in 18 months, I think I read somewhere that the vortex works better with hard ones, I have a RJX head so I'll have to find out where to order them from.
We did the trim flight, it came back +75/+10, do I need to do any adjustments or is this ok to leave as it is?
We run out of time today, so roll on tomorrow to complete the adjustments.
John said he was impressed with the tail & the overall feel was good, but he has not flown it full yet ,( only to test the set up).

Hi Tye,
glad to hear you fixed the gov; I was meaning to contact you and I forgot. There was a recent thread where someone said his servo was moving the wrong way and he needed to reverse it on the TX (as he had not seen that it can be reversed later in the gov setup). Then it hit me... if the throttle is not reversed correctly in the TX the gov corrections will operate backwards and will over-rev... go to full throttle in fact.

"I have a little tail wag at low head speed, but when in st1 & 2..."

If the head speeds are substantially different you will need to adjust each tail gain individually. The tail thrust changes when the head speed changes so the optimal gain for the gyro is different.

"...when you give big neg pitch the stop it sharply the heli bounces, this could be down to worn dampers."

If the bounce is on the elevator axis (tail bouncing vertical) adjust the "Ele Debounce".

If it like a random-ish wobble the stabilisation gain may be too high. Reduce the "Flybar Ratio" a bit.

I mention this to John when we got to the field this morning,,, after seeing Bob O's vid and him saying if the servo needs to be reversed change the setting from +100 to -100 for that servo. As we thought the vortex guv would think you are 85% throttle when you are actually only at 15% on the stick.

"I have a little tail wag at low head speed, but when in st1 & 2..."

Yes, I understand this just lack of time today.

"...when you give big neg pitch the stop it sharply the heli bounces, this could be down to worn dampers."

-Angelos

We thought it would be smoothed out with ele bounce, but as before lack of time and I want to make sure I read through setup / fine tuning guide before I make any adjustments.

I just glad that I did the model reset in my tx and the factory reset in the vortex, as I said previously I must have in knowingly adjusted something which cocked it all up leading to me posting problem posts with out cause.

Thank you Angelos for your support and to Dave, Andy, Nick and anyone else who tried to help me out.
Cheers Guys
Can't wait to get back over the field
