Logictech 6100T Gyro Setup Videos

[ferincr]

Please STOP thinking that everyone is wrong and follow the proper setup PLEASE....

Bob
Well, I'm sorry if I gave that impression I never said that anyone was wrong, I just intend to learn and the only way to do so is asking.:o
My apologies is I offended anyone I thought these forums were to clear my doubts and learn about new things.:dontknow
Obviously my way of exposing my questions is not the proper one.
I wish I could live in a country where I could check other people helis but I don't have that option, that is the reason I bomb the forums with questions. It's the only way for my to learn.
Thanks,

No problem.... Asking is OK but ya have to follow the advice too :D

Yes lowering your end points too far will make it look like you are limiting servo throw again this is NOT the correct way and will probabnly cause you to crash as you will have very slow tail control.

Bob

[ferincr]

Bob, believe me I DO follow the advice (especially when it comes from someone that it recognize to give the correct one:noteworthy).

But I didn't see any mention about this subject on the vid and it caught my attention when playing with it that below certain % it reduces the servo throw (which it doesn't happen with my 401 (I think) so I started to wonder if in this specific Gyro this function is different than with the 401 .

Now on this subject (and just because I also read the thread where you "review" someone's authoritative DVD's you have to agree with me that sometimes is even just for safety sake that is good to ask Why:shock:.

As a matter of fact I crashed my 60 due to follow the Futaba GY401 mechanical setup without questioning myself "what is the effect this is going to have on the heli"and I'm a bit weary now.
I watched your video (of the 401 setup on the TRex) and I did it as per the video and I analyzed the whys and it seems to make more sense than the futaba manual (at least it's a lot clearer).

I always say that I never left the 6YO stage (Why, Why,Why????):roll: I know it could be irritating sometimes, but I like to know things from the root and not just repeating somebody's else words.
Hopefully this explain a bit my Q's since the last thing I want to do is to get in anyone's nerves, especially when I depend on all of you guys to keep myself in the hobby.

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.

Bob

OK. I went back and re-read everything, watched everything and looked at my other [successful] setup. I made sure trims and endpoints are 0 / 100%. I centered the servo mechanically, I adjusted the limits, set the gain for 24% in normal (I've tried multiple settings) and tried exponential at 30% and 75% - with virtually the same results. I also tried reversing the gyro and/or the channel. I'm sure it's hard to vision so I also made a short video and put it on Youtube. Here you can see the problem in action. I'm hoping you'll see something and go ohhhhhhhhhhhhhhhh... I see what you're doing wrong - or tell me my gyro needs to go in for repairs!
Here is the link for the video:

I cant see how your rudder stick direction works or how the gyro compensates. It looks reversed! Show me a video of when you give a right rudder stick input which way the slider moves and THEN with the gyro in HH mode and you move the tail which way the gyro moves the slider. To me I think you are reversed!

Just want the folks who read this to know that your info helped me fix the problem!!!! I REALLY want to thank you for your assistance. I had reversed the servo direction in the gyro at one point but, to be honest, did not have everything set up properly mechanically so there were several things at work at that time.

Note to other viewers with the same problem - using the 6100T - I believe I reversed the servo direction (on the gyro) but did not turn it off and back on to "set" it as the Logictech manual suggests. Whether it contributed to my problem or not, remember to power down and then back up whenever you make changes (per the Logictech manual).

Anyway, the heli seems to be flying good in both normal and tail-lock modes. It looks like I even did a good job with the mechanical setup as I could almost let go of the controls in a hover.
Thanks again!!! Problem solved - at least this one! I'll see you in the "next" forum!!!

Hi Bob,
As a newbie I want to say a big thanks for your videos, I followed your series on the raptor e-620 build. I am building the e-550, initially as a pod and boom but intend to install this into a Bell 222 fuse later.
My question is that I see you use the gear channel for the gyro. What is the reasoning behind using this instead of Aux2. I would like to save the gear channel for the retracts on the Bell.
Thanks again
Reg

[Finless]

No reason other then on my smaller helis I only have a AR6100 and it uses Gear since there is not AUX2. Thus all my helis are consistant. But you can use AUX2 no problem if you like!

Bob

[helitaiwan963]

Well, my gyro caused me a hard landing today and breaking my tail


Well, I bring it up right? Then about 2 seconds later, the tail kick out on me(nose going left) and i try and correct. When i do this, it just swings back and forth. Out of control. Eventually, it got to the point where i got nose in:( I'm still a noob so nose in is a big no no for me. So i just droped the throttle. Any idea why this is happening? I'm in rate mode right now. I'm so confused...


Thanks

Hello Bob!
Your recommendations got me through the 6100T setup. Great... Thanks! Sorry to ask in this thread but do you have any recommendations on threads regarding Spektrum cut-out issues? I won't go into details here but bottom line: My helicopters are loosing communication between their AR7000 and R921 receivers respectively and the new X9303 transmitter. Could be a voltage fluctuation/drop issue but I'm not yet convinced.
Thanks!
Mike

[helitaiwan963]

anyone have their 6100T mounted on the side? like the LCD facing left or right? I have that and i can't get the gyro to hold worth a darn? think the placement has soemthing to do with it? I've done everything to try and set the gyro up correctly and this is the last thing i can think of...


Thanks

Well, either you are new or you are trying to pull a leg on us.
If in fact you are new on this and the question is for real, then yes, placement has everything to do with it.
Basically any gyro has to be mounted flat for it to work. If you mount it on the side it would correct vertically instead of horizontal yaw.
So make sure that the screen is facing up, it doesn't matter then if you mount the gyro to be able to read the screen from the rear, side or front of the heli as long as it's facing upwards (or downwards)

Hey Eric,
I recently installed that gyro on a T-Rex 600 and had a bear of a time. I've found that the more I struggle with these issues, the more I learn!!! Finless Bob's words (from this forum) guided me through safely. I just had to read them about 750 times!

That being said (i.e. I'm not an expert), I do not believe you will be successful in mounting that gyro on the side of your heli (as I understand your issue). Keep in mind what your gyro is trying to do (i.e. put yourself inside the gyro and close your eyes). When the tail moves left the gyro has to sense what direction it is spinning so that it can send a signal to the servo that controls the tail rotors and compensate (i.e. move the opposite way) for that movement.

The gyro can be mounted face up or dawn (obviously you would need to "reverse" it's commands if you're mounted upside down. You'll need to find a flat location either on top or the bottom.

Hope this helps!
Mike

[helitaiwan963]

Hey guys. I put the gyro on top and i'm still not having any luck. Can i just have a bad gyro? I have the gain at 85 percent. When i spool up, it just keeps piroing one way. then i move the stick the other way and then it'll spin the other way. It'll just keep doing that. I just thought my gyro was reversed to make sure, i just checked while it's on the ground. Everything checked out...Still the same thing. I'm gettting really pissed. Maybe it's a bad gyro? what do u guys think?

[HoverOver]

Happy Thanksgiving!
Shouldn't you be eating Turkey with your family? Oh yeah, me too. Anyway, your problem sounds very similar to mine. I had reversed the direction in the gyro but didn't turn it off and back on to "set it". Anyway, when I did do that, it started working!!! When I go back a re-read my posts I can see that they were not perfectly clear. However, if you are having the same problem it will probably make sense. I recommend you go back to page 8 and start reading the second post from the bottom. Then read the next few entries. Be sure to watch that WEAK video as you can see that my heli was doing the same thing you are describing.

Good luck!

[helitaiwan963]

I figured it out. I went back and watched finless's video. I realized, this gyro don't do anything if you reverse the gyro fromt he TX. So i went into the gyro and revered. PERFECT! Just some swash leveling and i'm set:D

I can't see anything but 4.8V on Logictech's website--can the gyro and servo run on 6V? Thanks

Did TP get an answer?

I too am interested if the servo can be run at 6V

Mick

[Finless]

I am running it on 6V but using a drop down on the servo just like the 611... Your OK running the gyro on 'regulated" 6V but put a drop down between the gyro and supplied 6100 servo.

Bob

[aussiemick]

Thanks boB

I'll get one before I fire the thing up!

Mick

[aussiemick]

I am fitting this gyro to my newly aquired TRex600NPro and would love to set it up under the canopy up the front.
I have the optional front gyro mount and have stuck the gyro down with the supplied gyro tape. Problem is the canopy wont go on any more. I can move the gyro back on the mount and give a 1mm clearance between the gyro and canopy and still have (albeit limited) access for starting.
Would it be acceptable to mount the gyro directly on top of the cyclic servos (Hitech HS6975's) using the supplied gyro tape?? Would I have to put a copper plate between the gyro and the servos?? If I can mount it on top of the servos this would give me about 4mm more room.
What are the ramifications of putting the gyro on the tail boom block? Will the exhaust smoke kill it or just make it filthy?

Thanks for the help

Mick

[Finless]

Thats a tuff call... I have seen people do that and I have done that with a 611 sensor before on my Vibe 90. I had no problems but I have seen some people have problems doing this. I would say try it and if you get weird tail kicks or drift add a plate.

Bob

[aussiemick]

Cool Thanks Bob

I went ahead and put the gyro down onto the servos and now I have heaps of clearance.

Just wish the blades had of been sent when the kit came ( forgot to get packed in the box) otherwise I would be flying tomorrow first thing.

Have a good day!!

Reporting back after the first day out with this Gyro.

I set the tail up (TRex600NP) so that the pitch slider arm was 90' (end point a 84 end point b 132) to the tail shaft and took the heli to the field.
Started it up and took it out for its first hover, I started in HH and the thing was rock solid (HH Gain 55% Expo 75%) I then flicked the switch into Normal (Rate) mode (Gain 50% Expo 75%) and there was no difference. Looks like I had the tail pitch spot on, I love it when a plan comes together. :)
After a few tank fulls I started to fly around a heap quicker and got a slight (fast) wag in the middle of turns. So I reduced the Gain in HH to 43% and the wag went away.

With a 1750 governed HS the tail gave fantastically consistant piros whilst flying with a goodly amount of airspeed. I will reduce the dual rate and expo the next time I go flying, I am getting a very fast piro rate which seemed to my eye consistant in speed both left and right.

The settings I have thus far using HH:
Expo 75%
D/R 100%
Normal Gain 43%
Idle up 1 (1750 HS) Gain 40%
Idle up 2 (1900 HS) Gain 37%

So far I havn't seen any problems with mounting the gyro directly to the servos!

Unfortunately the day ended early with a radio lockout resulitng in broken main blades and stripped TT gears. I am sure it was caused by my Quick UK base loaded antanae that I took off my HDX500 after it glitched into the floor. Moral to the story "do a range check before flying a new machine!!!"

Awesome! :thumbup::thumbup::thumbup::thumbup:

Love a success story man!

Hi Bob,
Thanks for another fantastic video series.
I bought a mostly build T600 "project" yesterday that had the Logitech 6100 mounted on it, but never flown.
Your videos led me through everything efficiently and giving me confidence.

Two questions:
1. What ESC are you talking about in the 3rd video- "The governer is holding really well". (Just curious- is Kontronik the only ESC with a fantastic governer?)

2. When you are adjusting expo to get piros you like:
Is it true that you can REDUCE rudder endpoints in the DX7 and it should ONLY reduce manual Piro rates, while leaving FULL limit to limit travel for the gyro to do it's work?

I was thinking reducing endpoints might be better than expo, since expo will INCREASE sensitivity in the outsid 1/2 of the stick range. Maybe linear is more controllable, if EndPoints are limited to the fastes piros you want?

Thanks!!
