I had this EG-380 gyro installed in one of my models (aileron). It worked fine. Now I installed it in my other model the same way I did in the first model (aileron). But now it is giving me a reverse action. What could I be missing? Please help me. I am sure it is just a simple matter. I lost the lost the installation instruction that came with it.

reddwarf (71%)
Turn the gyro upside-down that will reverse the action

hello out there!

Got some problems with this gyro: If i adjust the sensitivity screw, the servo is moving out of its neutral position. And of course if i trim it to neutral* i didnt have the full range oft the servo..

the signal wire for the on/off control didnnt work either. if i try to switch it on, the servo is moving weird and fast.

The basic function is working fine. Did make a test flight yesterday.

Does someone know if i make a mistake, or did i get a damaged gyro? Thanks !

This Gyro does not work well at full gain. You just experience the offsetting neutral. In regard with the signal wire: connect it to the signal pin of an extra channel of your receiver and you will get the equivalent of turning the sensitivity screw when you turn the knob in the transmitter of the said channel.

It is the same problem with every gyro of this type. Too much sensibility screws it up!

Moggs (74%)
Just Test flew my Yak 54 55" span. Model had tendency to stall one wingtip on tighter turns. Using Gyro rudder correction on about half sensitivity sorts it out. When sensitivity is increased rudder moves sideways, so need to adjust sub trim programming in TX to bring TX flight trims back to neutral for flying.. Not game to adjust in flight, rudder moves off centre. Flying in 15/20mph wind was much easier. Also have gyro on elevator.. Works a treat.

I noticed when I change the gain on the gyro, it actually moves the surfaces, i.e., it changes the trim. The more gain there is, the more the surfaces become off. This causes a problem because if I try to turn the gyro on and off in mid-air, the trim is changed, sometimes drastically* obviously not a good thing.
Can someone tell me their thoughts on this? Is there a way to fix this problem?

Also I expected the gyro to hold the control surface until the plane is level but just seems to blip the surface, can't see how this will work to keep the plane level.

I'm using HK 2.4 6ch reciever and hxt900 servo's.

I ordered 2 of these (thought the first was faulty!!) and both are the same.

Any ideas?

GRAHAM (37%)
The blip is a corrective input. momentary input will level the plane

Such Is Life (44%)
This gyro won't put your plane back to level, only 'halt' or dampen any movement on the axis until it stops. That's why it only blips. While rolling right due to a wind gust for example, the gyro will adjust trim left (agains the unwanted roll) until the roll stops.
A headlock gyro would hold the control surface after movement stops, until it returns to level.

Someone on Reviews Tab mentioned something about the servo pulses needing to be in the correct order (for gain and the channel being controlled by the gyro)... does this gyro work correctly with the newer 2.4 ghz receivers which signal ALL servo channels at the exact same time? I have an older Art-Tech gyro that went haywire when I tried it on one of my newer rx's, it didn't like getting the servo signal pulses on both channels at the same instant. Thanks!

kinkonraf (67%)
Please do the test and inform Us.

Marcin (12%)
My TG-380 works correctly with my Walkera 2801Pro, one channel for turning on/off/sens. of the gyro, others occupated by servos.

Grunta13 (50%)
that means when one goes up the other goes down at the same time just to be clear

Marcin (12%)
Yes - byt you have to use Y wire.

Grunta13 (50%)
do i need a special connector to connect the 2 rx outputs to the 2 aileron servos i want to control? ailerons are not independent of input as in one up one down on a left or right stick input so I'm not sure what to do

Runny (41%)
This should be connected between the Y-Cable an the RX.

If you're using mixing on the RX because of a reversed installed servo you will need to turn it 180 degrees

kinkonraf (67%)
You do need Two Gyros, one for each aileron, oriented properly of course. The only way to control two servos with one Gyro is if you use a "Y" cable, or you use a mixer device after the receiver. This is not the case if you mix at transmitter level.

Marcin (12%)
You need simply Y connector

this unit can used anolog ore digital servo?

Malfamartin (71%)
Both of them, but most people recommend digital servos. Fast response is the key issue. Some people also prefer MG (Metal Gear)

kinkonraf (67%)
Can be used in either.

Marcin (12%)
I use analog, and have no idea what about digital.

Whats the single wire for? Gain adjustment or switching it on and off? Its not pictured nor mentioned in the manual.

kinkonraf (67%)
See my reply to Christian above.

Marcin (12%)
On/off, but if you use proportional channel, it can works as a gain too.

radialarm (28%)
Gain control wich also turns it on and off by limiting it's effect.

Hady Esta (49%)
the single wire is for switching on and off

Teddytimo (59%)
I can't realy beleave the single connector for Aileron.
I'm using different mixers in my TX ea. Aileron and flaps etc.
It will not help my to use a V-mixer because all other mixing an my glider ist obsolet then.
Why does the Gyro dont have 2 Outputs?
Overall a single Aileron Airplane does not make my nervos while starting or landing.

bracam1966 (19%)
il faut deux gyro un pour chaque servo d ailleron..et les monte de facon a avoir une correction symetrique haut bas.

kaon01 (67%)
Hi,
I can understand how this would work for AILERON with a Y-cable for 2 servos.
But what if you want to use L and R ailerons on separate channels? (for flaperon/spoileron ability).

Please clarify if this can be used if one uses 2 separate channels for L & R ailerons.

kaon01 (67%)
Oh... not possible without using a mixer between the gyro and the aile servos. Nevermind then.

Marcin (12%)
Than you have to use different gyro (or two gyros). This model has only one channel, so only one separate servo can be use.

bracam1966 (19%)
oui mais deux gyro monte symetrique haut bas..de facon a se quil corrige bas haut..bon vole

Hi I set one on my plane and connected it to the ailerons it works find but I am not able to switch the Gyro off. I am using Futuba T7C and connected the single pin to the middle pin of Channel 5 (Landing Gear). I set the switch G (to turn it on and off) but nothing happens and the Gyro is always on- when I put a servo on the same channel it seems the switch works fine and the servo arm travels according. Please help...

Shahab (48%)
Hi everybody -I found my answer by reading others comments carefully the pin should not be connected to the middle pin the right pin on Futuba Rx is White and as recommended above - happy flying

kaon01 (67%)
I bought two TG380.
One of them turns off as expected. (green LED remains on, but movement stops)
The other one cannot be turned off.
I am connecting the single pin to the signal pin of my AUX1 channel of my AR6110.

martinl (46%)
I am reading mixed reviews here..I have tried it on pitch and roll with 2 units on a Y joint to turn it off and on, I have been testing it for 2 weeks, the response is pretty ***r even playing with the gain..too much gain actually changed the control surface trim??? This is the same result with 2 other club members. There is NO WAY u can use this to stabilize your plane like an autopilot.
It will come good after 3 -4 seconds..too late..crash$##&^
Can any of u guys who has tested it successfully tell me what servos are u using..how fast????

ishady (63%)
I bought this gyro 3 pcs.
Seem havent find a right way to installed it in my coaxial (I installed it cable to the front but led face left), seem a post noted that it dont cooperate well with mixer.
Installed it perfectly in my limbo plane's rudder thou* same as the heli I installed it cable to the front but led face left (I hope I am not installed it wrongly) but I test it first by turning the plane left and the rudder move right and vice versa.
TEst once in a very windy shore and the plane flew straight.
Need comments, guyz! Thanks ALL & HC.

Does the Turnigy TG-380 Gyro have a reverse switch?

kreot (98%)
No, you reverse it by flipping it over

Robert (80%)
Thanks Kreot. That makes sense.

Neutral point of control surface change modifing tha gain exactly as Yosemite wrote:
"I noticed when I change the gain on the gyro, it actually moves the surfaces, i.e., it changes the trim. The more gain there is, the more the surfaces become off"
Someone could show us how fix the neutral point switching on/off the gyro?
Thanks

ishady (63%)
This is weird, it dont happenned to me thou.

FreeStyle07 (86%)
Some people seem to use one gyro on the ailerons even using two different channels for left and right wing. How do you to that? Do correct just one aileron for stabilisation?

kreot (98%)
You connect the receiver to gyro, and gyro is connected to mixer (v-tail, elevon flying mixer) and aileron hooked in to mixer.

kreot (98%)
I tried to hook the wires as i said earlier and i get weird jitter on one servo and the other works fine, no matter if you change servos/channel the jitters continue. It has something to do with the gyros abilities to deal signal to mixer and there to servos. I quess you have to use 2 gyros for 2 servos in ailerons. I tried to reverse channels, add/remove mixes from radio but nothing seemed to help. Need to explore if someone has done it some other way..

pilot_dragonfly (84%)
Is it possible to use three of these gyro's for a three axis control on a vtol aircraft if setup correctly?

FreeStyle07 (86%)
yes of course. Every axes is independant from the other if you place the gyro exactly in a particular axes

laserist (45%)
I bought two of these as well as a GWS V-Tail Mixer II to stabilize the pitch and roll of my elevon delta wing FunJet.

Setup:

-Multiplex FunJet
-Spektrum DX5e / AR500
-Turnigy TG380 gyros
-GWS V-Tail Mixer II

Having trouble getting this mixer to co-operate with the gyros, disabled on-board mixing, when pulling down on the stick the elevons work correctly but pushing up on the stick causes the elevons to move erratically. Same problem when moving the stick left-right moving left the elevons perform normally but moving the stick right causes them to move all over the place.

Someone commented in the reviews of the GWS Mixer that gyros might introduce signal delay which confuses the mixer but I am unsure as to how to correct this problem.

Without gyros the mixer works perfectly. Also with only one gyro (either pitch or roll) it works perfectly, just not with both.

Anybody with any suggestions?

If you have Futaba PCM you might need a Digital Servo Buffer from FMA Part Number: 505SB

Brent (84%)
Hi Yosemite. I ordered 2 of them, and one did the same thing you've just mentioned. I think it's faulty - the other one doesn't change the trim at all. Think you should send it back for replacement, or just order another one.

Flying Goat (72%)
Hi.
I have the same problem, gain can be altered on an Aux channel but the trim also moves as I increase the Gain. Would be interest to know if this is a definite fault. Can't remove this by mixing. Perhap HK could comment (please).

Can I use this also on my airplanes rudder to control yaw especialy during takeof and landing with a taildragger?

Sloperdude (64%)
Sure. just mount it so that it responds to yaw.

Does anybody knows this Gyro has AVCS system like a Futaba GYA350 ?
And is it available mounted on ailerons, elevators and rudders ?

Ludde (60%)
This is not a ACVS gyro, just rate,, ie. it will not retunr to compass heading, it will just stop unwanted movment, you can mount it on any control surface.

Dr. Katana (90%)
Thank you very much, Ludde.
It is as same as 'Futaba Normal Mode' function.

mandis (67%)
i just recently purchased one. now i'm little bit lost regarding the single wire.. i have tried connecting it to the signal pin of the gear ch. but nothing happens.. have i missed somthing?
olmod said it should be connected to the middle pin? isn't he middle pin is the positive pin.
please enlighten me.
where it should be connected and what setting should be done on the transmitter?
BTW i'm using a JR9x2 and been using it futaba gyros and no problem at all..

kaon01 (67%)
I bought two of these.
Turning off using the single-pin works on one of them, but has no effect on the other.
I connect the single-pin to the signal pin of the AUX1 channel of my AR6110.

worldedit (67%)
Is there a reason why i shouldnt use this in a helicopter?

pilot_dragonfly (84%)
You could use it for a heli, possibly something small like hbfp, blade, hbcp2 or similar. The only difference will be that using it on a heli the gyro will have to be mounted horizontally by it's base rather than vertically. Hope this helps!

Sloperdude (64%)
I suspect that this isn't as fast as a heli gyro. They usually use very fast servos, where airplanes normally don't.

Malfamartin (71%)
Why so complicated Marco? I did this for you!
quote: Contrary to the contents of the instructions, this is a dual rate piezo-gyro, i.e. it can be remotely adjusted from a transmitter featuring ATV (much better !). A non-remote gain adjustable gyro has only a trimmer you can use on ground with a screw driver to turn for more or less gain. A remote gain capable gyro has an extra plug (this one) that one can connect (signal pin) for example to the the gear channel (CH 5) to change (on/off) the gain. The gain or sensitivity is basically servo travel versus angular acceleration. Imaging this as a straight line with a certain slope and an intercept on a coordinate axis, the trimmer simply shifts more or less this intercept without changing the slope, i.e., at the same acceleration you can have more or less servo travel. In flight, with the gear switch set to “ON”, you will fully use this servo travel (100 % of trimer ground setup) or, with gear switch set to “OFF”, you will zero it (piezo-gyro transparent). Even more, if you can associate your gear channel to a rocker on the transmitter you can step adjust the gyro response from 100% to 0 % (of the trimmer ground setup).

olmod (72%)
A couple of things buyers should be aware of ,
To the novice there is no diagram showing wich pin the single wire connects too on your RX ,usually it is the centre pin on AUX.
if you alter the sensitivy you must re adjust centering ,i found interaction ,bearing that in mind its ok to go.

Ludde (60%)
Singel pin wire sould NOT be in the middle of any socket unless you use a stoneage Sanwa radio, it should be in the signal pin place, yellow/orange or white on normal servocables, compaer against your other calbes in your rx=receiver, the other middle positive and the last negativ pin is not used since it already got power from the ohter cable going to the rx.

Michael (67%)
Does this Gyro sense rate or position?

Eric1180 (-53%)
Yes they all do.

Motrax (85%)
Rate. I rolled my airplane and left it there and the ailerons went back at neutral position.

Lloyd (79%)
Hi, If my plane has 2 servos for aileron, do i use two gyos set up like this. Reciever to gyro to Servo1 and Reviever to Gyro to Servo2?

Please let me know
Cheers

Ren (78%)
If you are using a Y-splitter cable to run your ailerons then you would need to place one gyro between the RX and the Y-splitter cable.

If you are driving the second aileron servo via an extra channel (programmed on the TX) then you will have difficulty in installing. You could try the 2 gyro method you mentioned but you would have to adjust both gyros to the exact same sensitivity/rate of throw and have them mounted on the same axis.

Dennan (72%)
My Eurofighter have Deltamix so i use 2 gyros, one for each ailron. works great.

Klaus (54%)
The gyro has the standard 3-wire cable plus a single orange cable with a female plug. This single cable is not mentioned in the instructions, what does it do, where is it to be connected?

Ren (78%)
In the reviews, Gene mentioned the following:-
Gyro screw = sensitivity
extra wire = maximum servo travel in response to axis rotation

So it would appear that if you connected that extra cable to the receiver you could
a) switch the gyro in and out (zero throw<->max throw via a switch input on your TX)
- or -
b) adjust the maximum throw with a variable signal from a VR input (like on the Futaba T10CAP VR knobs)

So according to what Gene reported, option 'b' would allow you to adjust the gyro on the fly.

Hello, does any one know when this item will be available again?????

webber (98%)
Almost all of the items are supplied within 2 weeks (max) so sometimes a great patience must be needed )

P.S. I myself sometimes can't wait for more than 2 days and buy a much more expensive products (
