Logictech 6100T Gyro Setup Videos

[528hemi]

I think my BETA release is causing me grief...I agree I only went to BETA because others said it fixed a problem with the GOV but I see you are not having problems.

It come down to me testing and seeing what works...everyone runs a slightly different setup and to many variables are in play....I think it has to do with the A123 cells and how they drop alot of voltage during a load...the headspeed must be dropping (pitch is 12/12) and the added pitch causing excess torue that the tail/gyro cant handle...

I guess for a sport setup I should not be running 12/12 pitch to start...IF I want to run 12/12 pitch then the headspeed needs to be probably closer to 2100RPM...

Going to test mroe this weekend but I think I am now on the right track

Bob,
I really want to see your videos on the 6100t gyro setup, but for some reason I can not access them. Do they expire after a while? Can you repost them?

Hi Bob,

Thanks for going throught the trouble to make a video on this gyro. I have one on my Trex Nitro Pro, and this weekend I am going to set it up in normal mode like you said to see if it improves my tail control.

I have 2 questions.

1. You said in vid 1 to try Standard Performance in Head Lock mode, but then you said in vid 2 that you found out it worked best in Highest Performance at the field. Why did you have to go to Highest? What did it do or not do in Standard??

2. Just out of curiousity, why does this gyro need to be set up in normal mode, whereas all others can be set up directly in Heading Hold/Lock???

Thanks again!

[Finless]

Actually most gyro's are suppose to be set up in rate mode first! Even the Futaba 401 and 611.... For most people they perform fine not doing that but for best performance you should set up in rate mode.

I found high performance locked the tail better and have less of a bounce when coming out of a piro.

[Rockohaulic]

Thanks Bob.

You mentioned setting gain to 50 in normal mode for the hover flight.

Is this the max gain setting (i.e for my Futaba TX that would be norm mode at 100), or is this the mid setting???

[Finless]

Gain of 50 in the DX7 is 0 on the gyro. So with futaba set it to 0 or whatever until the gyro show 0 and is in normal mode.

Bob

[Rockohaulic]

Got it.

So a gyro will operate, and you can fly at zero gain??

What happens to the setup if you have to increase the gain in normal mode?

Sorry for all the questions, I've never set a gyro up in normal mode.........

[Rockohaulic]

OK I went to the field and tried it in normal mode. I set my gain at 3% in normal mode and tried to bring the Trex 600N into a hover - it was a handfull! It would go one way and then I would overcorrect and it would go the other way. I could not get it to stay still at all. I quickly gave up because I did not want to put the heli in (I was worried about tipping and putting the blades in).

So I bumped the gain to 25%. This was better. Now I could get it into a hover, hold it steady, and tell which way it was drifting. I changed the length of the tail rod, tried it again, and she was holding fine. At this gain I was able to comfortably set it up in normal mode.

So, as an experiment I tried 2 things. I kept it at 25%, and turned the link 3 turns to set the tail more or less back to center. I wanted to see if with the 25% if this would still show me that I needed to adjust the tail, or with this gain would it hold the tail. Sure enough it told me I needed to adjust the tail as the nose turned left due to torque.

Then I added the 3 turns back in. This time I wanted to see what it would do with the tail mechanically correct if I brought the gain back down. I brought the gain down to 5%, brought it up into a hover, and it was all over the place again! It was very very difficult to control with the rudder stick - even though now it was set up correctly.

So, in my opinion, with a Trex 600N, you need a bit of gain even in normal mode to control the heli!!!

Just my 2 cents worth.........

I have this gyro in a Hurricane 550 and set it up in NORMAL (RATE) mode, on switching to Tail lock mode the servo will not return to neutral after deflection in any direction.
Luckily I tried it on the ground

Using Spektrum DX7 radio with 7000 RX
TX Settings: input select Gyro to AUX2
Gyro Sense Rate mode(0) is 35%
Tail Lock (1)is 52% or higher

All the trimming flights and settings were done in Rate mode as per the instruction book and the Finless Videos . Test hovers in that mode were good

Now when I want to fly in Tail Lock mode the tail rotor stays where ever it is deflected too. Yes I have tried flicking the mode switch(rudder Dual rate on the Spektrum DX7)but the neutral setting just seems to be NOT there, In Rate mode it always returns to neutral

Do I have a faulty Gyro or am I missing something in my set up.

Urgently need help, PLEASE

[Finless]

on switching to Tail lock mode the servo will not return to neutral after deflection in any direction.



This is normal for any gyro with heading Hold (tail lock). It wont work like this in the air!

[krakerjak]

Hi Bob,

Thanks for that info.

I used your 6100 videos as a guide while setting up and have hovered in NORMAL mode as a beginner again after 35 years of other activity, planks etc. (see my profile)

If I initialise the gyro in NORMAL mode and then switch to TAIL LOCK the neutral setting is different,
Should the neutral settings be the same?

Should I reset the neutral in Tail Lock and never use NORMAL again?
Or, is there a way to get both neutrals the same
DOUG

[Finless]

On the bench NO you wont get the same neutral points. In the air in a hover YES... Realize that in HH mode the gyro will do whatever it takes with the tail slider to HOLD the tail while the stick is at neutral.
The reason you want to first set up in rate mode is to get the servo arm 90 and the pitch slider where ever it needs to be to hold the tail in a hover.

On the bench HH mode will not make sense and do weird things that you as a person looking at it doesn't look right. Just remember in the air the tail OPERATES and the gyro COMPENSATES. On the bench you cant see this operation.

I hope that makes sense.

Hi,
I just bought a LTG6100T to mount on my Millenium 2.

I am wondering where and how to mount it. Does it have to be in a certain position to correct on the right axis?


Antoine

[Finless]

As long as it is level withb the top main shaft bearing you should be fine.

Bob

[nimco]

OK thanks,
So the following setup should be ok (see attachment)?
Antoine

[Finless]

No... the display MUST face upward. Also make sure it is mounted on a hard surface that wont move around. I dont think a fuel tank is a good place. Then when attaching to the surface use some 3M foam double sided tape to act as a shock dampener or the gyro will pick up vibrations from the engine.

Bob

[nimco]

Ok thanks, This is a carbon plate, just below the fuel tank.

Hi Uncle Bob (Thats the name I gave you after you unknowingly helped me set up my T-Rex 450) or "friends of Bob",

My Setup:
• 600CF - 600XL w/stock ESC/BEC
• TP Extreme 5000mAh (6C)
• JR X9303 & matching receiver
• Logitech 6100T

My Problem:
Following your instructions per the 6100T setup video (i.e. setting up in normal mode): I have done my best to get er' set up mechanically but nevertheless the tail wants to go left (hard) when I start to bring it off ground. FYI: I hooked the gain lead to Aux 2 port (instead of port 5) on receiver and use the gyro menu to adjust the gain. I have tried every combination of "mechanical trim" (i.e. a little left, centered, etc) and increased / decreased gain but still does the same. I can [barely] control it by applying a ton on right rudder... So, for now, I have simply increased the gain until I am solidly in head lock mode (showing about 35% on the gyro) and am able to get her off the ground safely. I hesitate to do much more than a low hover until I figure this out.

Anyone have any ideas?

[Finless]

You need to reverse the gyro direction NOT the rudder channel reversing. Sounds like the gyro is set for the WRONG direction.

Bob

[HoverOver]

Thanks Bob,
I tried your suggestion and no change. I went back and watched the videos and re-read through all 7 pages of this thread and tried most of the suggestions and ideas posted here but it only gets worse... Another strange phenomenon I noticed today: As I spool up (i.e. before hitting positive pitch), I notice I have no rudder control. Now if I gently (and I mean GENTLY) add positive pitch AND add maximum compensatory rudder, I am able to at least get it up without pirouetting wildly.

This is my first big heli so the thought of this thing pirouetting without my consent scares me to be perfectly honest.

One more thing... As I spool up - and then add rudder (still on the ground), the heli power fluctuates greatly. Strangest thing I've ever seen. Anyone know any RC Heli experts near Santa Barbara, CA?

Thanks!

[Finless]

OK please understand if your spooling up on a hard surface the initial torq will cause the heli to spin a little. This is because the tail rotor is not going fast enough to compensate for the initial torq. You need to be almost up to head speed before that will stop. I assume you have soft start enabled on your ESC? If so try spooling up on a piece of carpet or on grass. Now once the heli is up to sped try very lightly lifting off the ground. If your gyro reversing switch on the 401 is correct it should not try to spin.

Thanks for your help Bob..
Do you have a paypal account? I'd like to contribute to you - maybe start a trend? How about a brand new Pelican Case for one of your radios? Your stuff - even if not Hollywood production perfect - is helpful to so many people that there should be a way for us idiots to reward you. Now when I go back and listen or read, I feel like I'm hangin' out with an old friend (hence the comment: "Uncle Bob").

In any event, I've done nothing to the ESC (factory settings) but I'm not convinced it is just the initial torque. I'm not an expert by any means (I've been flying/building for about 3 years). but I have built several 450's successfully and have always been able to work through the issues... this one is different. That is me on the court shooting from the bottom of my T-Rex 450SE.

This time I am not sure what is going on. I'm starting to wonder if there might be a problem with the Logitech 6100T???? I think I'll throw a 401 I have on there and give that a try. I'll also go through the ESC and make sure the settings look good. May not happen for a couple of days - I'm scheduled to go back to the Firehouse for the next couple of days...

Do you recommend Governor mode or use of a throttle curve? What settings?.
Anyway, thanks again and let me know about the offer!
Mike

[Finless]

Cool shot.... Yea OK if you have set one up before and know what it can do then yea... something is not right! Could be the gyro. On the bench if you move the tail by hand do you see the servo adjust for yaw in the proper direction?

If so do you have the plastic belt pulleys on this heli? If so check that one is not stripped and slipping on the shaft... Just an idea.

As far as donating. Thank you but seriously no need for that! But again I appreciate the thought.

Bob

[ferincr]

I just watched the video and did the normal mode setup (I'll do the test fly this weekend)
The question I have is: On the TX (Futaba 9CHPS) the ATV is it the same as for the GY-401? I mean it just adjusts the piro speed? or is it different with this gyro?
I'm asking this because I noticed that if I lower the values quite low (around 45% in rate mode) it does reduce the servo travel but over that value it doesn't.
I just want to make sure what to expect next time I fire it up so I don't do with my R90SE what I did with my R60:o.
Thanks,

[Finless]

YES it will do that but your tail will be SO SLOW you WILL have problems... Please STOP thinking that everyone is wrong and follow the proper setup PLEASE....
