I have read many article about Setting up HH but a lot of confusion. At last I have got the solution and managed to set My Trx and this gyro to HH mod. I take back my word from previous statement. GA-410 and Corona Syn 8C35mhz and Imax-9x matched. Video next time. Setup see: Gyro Sens
   Yesyns (27%)
Even though I managed to set My Trx and GA410, the tail still wags little bit. I use HXT9311BB servo (SSV-9311BB)for the tail. When advance throttle faster,the tail swing to turn head to left, made me a bit shaky!. Anybody who SAID this gyro was rock solid could tell us what SERVO are you using...any original video?
   Yesyns (27%)
Since nobody reply, today is my last attempt to prove this gyro is HH but FAILED(disaster). My heli crashed 4 times already and the problem is still the same. It is more stable in normal mode flight and hovering. I have to get other new brand gyro. I have practiced on simulator almost every day! What can I say? Now I beleived on what other friends complaints about this gyro.. Good friend helps others.... :{

Short Video: htt p://ww w.hobb yking****/hobb yking/store/HK_movies2.asp?idmovie=8c01cadf73c04185828ad2a0fcc1bfd5 . GA-410 and Corona Syn 8C35mhz is not good combination. Tail will not Hold when you push powerUp quickly. Still can fly at normal flt. HXT900 is not for heli tail servo.... See me in the Video

I have tested this gyro(combination of Imax-9Ch(Trx), Corona 8Ch 35Mhz(Rx), 4000kv motor, GA-410, 4pcs HXT900 servos). The result is not HeadLock and crash twice. HXT900 servo not last long about 30min life. Corona 8Ch not match with GA-410.... here pic of the setting I have done: HH setup

I tried this gyro with Imax9c RX not working(led blinking red). After I received Corona 8C 35mhz, connect it to this gyro it initialized, steady red led on and the led lite off after 3sec (probably TRX setup normal mod). Shake the tail, the tail servo move too. Seem working. This website might help: ht tp : //ww w.assan.cn/main/index-news-12-en.html
   Yesyns (27%)
For Original Imax Rx, set back the Imax Trx to CPM. The gyro will initialise. For Corona set Imax Trx to PPM. I did not find the LED light on when gy is set to AVS mod. But the servo responds to the movement of the tail... and also I can adjust the gain from Trx...

How to reset factory settings in GA410 gyro? The issue with mine is that I'm not able to switch it to the HH mode ( led ON), I have Eclipse 7 transmitter and led is ON only when Gyro is between 47 -51 then above 51 led is off and below 47 it is off. Is it possible that Gyro is broken becouse when initiated it in normal mode ( below 50) I switch it to the 90, whenI do this the led is on but nothing works , please advice how to reset this gyro or bring back factory settings, thanks a lot

Great ! Just received the new GA410 PRO version ! It as Delay and Limit adjust potentiometers and switches for servo selection (normal or Digital)and normal or reverse selection. Really the same as the Futaba 401 !
Thanks a lot HobbyKing !

HI GUYS! CAN ANYBODY TELL ME WHAT IS THE DIFFERENCE BETWEEN TAIL LOCK AND HEAD LOCK GYROS? THANKS
   Jonathan Ott (47%)
No difference, just different wording. Head lock is short for Heading Lock, and tail lock just means the gyro locks the tail into a heading.

Incredible response and tail holding on an old T-Rex HDE450xl.
Make sure to use an on and of switch when using a Synthesized Receiver

dear all,
works this gyro with a 2,4ghz receiver like corona v2 or assan?
thanks for your help
   Kees (63%)
hi,

i use this gyro with a HK450 and Assan 2.4 receiver and it all works perfectly well ! Even with a cheap analog servo the tail is quite stable.

In fact I don't see any reason to buy it's much more expensive cousin with a very similar name ...

good value for money !
   woolf_66 (63%)
hi kees,

thanks for your response, so i will use this gyro in my trex 500 and corona v2 2,4 ghz receiver

Hi, Friends, If I don't have the transmitter with gyro setup, how I can choose the tail lock mode? this gyro work with the hobby king 2.4ghz transmitter? Thanks a lot for the help.

I'm looking to build a HK450 using this gyro. What servos are confirmed to work well with it? I keep reading about people having problems with certain digitals and analogs?
   rossco34 (70%)
Ino-Lab digitals work great with this gyro!

Andrew (86%)
Does anyone know if it is ok to mount this gyro upside down? I want to put it underneath the boom on my HK450 as is recommended to avoid it getting hit by the blades/paddles in a crash. I'm Unsure as it has the 'up' arrow on it
   Roadrunner666 (80%)
It doesn't matter if you turn it by 180 degrees on X axis or whatever degrees on Y axis.
So yes, you can mount it upside down.

sorry, but the weight of gyro is 15gr, but in the package it's weight is 110.....
ok stay safe, but so too is

Biggles (85%)
Plug it in and the servo and gyro were dead, no LED not servo action. any ideas
   Roadrunner666 (80%)
Are you shure you have it well conected to reciever?
There are only a little of bad pieces of gyros, but it can happen.
   Biggles (85%)
Yeah even checked for stray plastic in the connectors.
Re attached my old one and it worked fine..
It looked as though it was used so I have my concerns.
   Biggles (85%)
Sent it back and eventually got an email that they've sent another after other one tested bad..
   Biggles (85%)
I take it back, not shipped yet, it's "Waiting Management Approval" ???

Roadrunner666 (80%)
I've been using GA410 with HD-1810MG digital servo and it didn't drift on howering but in and after flips it drift even to diferent ways, so its was pretty hard to corect. I swiched to HXT900 and it was suprisingli better but still making same kind of drifting. I made few flips with it but dont recomend to do so. Can recomend for howering and begginers flying. Now ill be getting GWS Park HPX and on recomandation of jpqabz MKS-480 so ill let you know.

Roadrunner666 (80%)
Please with which servos can i fly 3D with Assan GA410? It would be nice to make some list here.
   jpgabz (76%)
the mks ds480 works perfectly with this gyro
   Roadrunner666 (80%)
Thx for answer. Could you specify works perfectly?
Can you do flips or rapid cyclic pumbing without tail drift?
Thanx a lot.
   jpgabz (76%)
yes I can, there is no drift, this servo is very fast and fully compatible with the GA410. follow my instructions for setting mentioned above, no trim / sub in the boot trim, neutral mechanical 0 ° and the gyro will be fully operational. This is a very good combination and this gyro is absolutely remarkable for its price!
   Roadrunner666 (80%)
I've got my ds480 and i really was surprised with the performance.
You write that there is no drift but it seems to me I won't be able to get rid of temperature drift which is pretty strong even in small temperature changes.

Ce gyro fonctionne remarquablement bien avec le servo MKS-480 et le AR6100, j'ai eu du mal ā comprendre comment le régler au début mais en fait c'est assez simple, voici ma procédure :
1- ne mčtre AUCUN trim ni sub trim
2- régler le palonier du servo ā 90°
3- régler le neutre mécanique avec un pas ā 0° et régler les limites
4- initialiser en mode HL
5- ajouter du rudder trim si besoin pour stopper le rampage du servo.
6- pour chaque réinitialisation il ne faut aucun trim ni subtrim, refaire 5 ā chaque initialisation.

on peut initialiser le gyro depuis le TX en basculant de HH ā HL deux fois de suite rapidement
Grâce ā cela il verrouille parfaitement, c'est un super gyro !!!

This gyro works remarkably well with the MKS-480 servo and AR6100, I had difficulty understanding how to adjust at first but in fact it's quite simple, here is my case:
1 - NONE trim or sub trim
2 - set servo 90 °
3 - set the neutral mechanical one step at 0° and set he limits
4 - initialize mode HL
5 - add rudder trim if necessary to stop the drift of the servo.
6 - to initialize each one should not trim or subtrim, repeat every 5 for every initializations.

can initialize the gyro from the TX switch from HH to HL twice quickly
Thanks to that it locks perfectly, it is a great gyro!
   Roadrunner666 (80%)
Thx a lot.
In step 3, do you mean neutral mechanic as non drifting in non-headlock mod with low gain?
   jpgabz (76%)
the neutral mechanical must be 0, to have a perfect symmetry for setting LIMIT, the gyro correct the drift continuously. Therefore, we use only the headlock mode.

can i use mks ds480 with hk 500 thanks

jezza (87%)
Ok I have a HK45 and the Assan GY410 with a Futaba T6xas and I can not get the gyro to work and tips would be greatfully accepted, Many Thanks and a thousand points to your credit
   jezza (87%)
OK THE GY410 IS NOT COMPATABLE WITH THE CORONA DUAL CONVERSION RECIEVER
   jezza (87%)
Does any one have a work around
12/04/2009
Bret (51%)
Ant trick to getting this thing to work. I have it all hooked up per the manual, but all it seems to do is limit my servo travel to about 50%. There is no response from it at all when I swing the tail of the heli. I have tried this with both digital and analog servos and both react the same way, no response from the servo no matter how I movethe heli. HK-450 on Spektrum Dx6i with AR6200 RX, gyro on rudder with gain lead on gear channel. I am totally new to heli's so I am guessing that I must have something setup wrong and the gyro is probably fine.

Southbend (89%)
I have been using this Gyro on my HK450, I can't seem to get rid of the Tail Wiggle on windy days. I have turned down the Gain to about 30% that makes it better but still present. With the gain up higher it is even worse. I have tried many servos .07 speed all Digital with no success. I have made sure my servo horn is as close to center as posible and have a very straight line on the control linkage to the Tail Rotor.

Any suggestions please?
   Southbend (89%)
Something I forgot to mention is that sometimes I have to disconnect the power and reset the Gyro from wanting to spin left or have to hold right rudder to keep it from spinning, I wouldn't say this is drift because it really pulls left hard.

kamikaze63 (54%)
can i use this gyro in my raptor 30 v2,?
   jcer93705 (58%)
You better use the hobbyking gyro. http://hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=10113&Product_Name=Hobby_King_401B_AVCS_Digital_Head_Lock_Gyro_

It is a xmhobbies g401b which is great gyro, i cant tell the different compare to futaba g401b. I have xmhobbies g401b which is the same of the link i gave you, its on my raptor 30v1

fr4nk1yn (50%)
I've been looking for info for a few days now on setup.
I set up according to how I understood the directions.
It is on a planes rudder.
Once initialized it pulls the rudder to one max right.
The only way to make it even appear to be functioning is by then using the TXs trim to ceter the rudder.
Mechanical centering doesn't work.
A Fututaba HH works as is expected.
Either this is not HH but "dual rate" or my setup is totally wrong.

Ideas?
   shogun19 (72%)
You have to adjust out the drift. Use rudder sub trim. put gyro in heading hold mode adjust trim till it stops drifting go to hh mode for 30 sec or so switch back to rate if it moves add more trim go back and forth till it does not change when switching from hh to rate. One of mine took L25 to stop drift seems to depend on your servo.

Assan GA-410 Tail Lock Gyro or GR302-AD - Telebee Head Lock & Standard Gyro (Digital/Analog)for a HK450
The price is similar but so fare as to what I have read is that the Telebee look to better solution, any comments please

Hi
I'm looking for a good tail servo to work with these gyro, there is any at hobbycity ? (on trex 450)
   jpgabz (76%)
the mks ds480 works perfectly with this gyro

Michael (63%)
I'm considering to buy this Gyro for a Zoom 400. Will it work with a Hitec Eclipse 7 Transmitter?
   Nicolas (88%)
No problem, it works.

Just received a GA-410 and plugged it in with out the LED coming on and it would not work.
Plugged it into the RX and servo with no action.
Any thing I'm doing wrong?

is this gyro GA-410 work better then G110 is the original from the blade 400? any one please thank you
   telang (75%)
I replaced the original gyro on my Twister Storm3D which I beleive is the same as yours, and the 410 works alot better.
   Flyextreme (91%)
Just about anything is better than the G110. I ordered a GA410 to try. I have 401s on all of my other helis....we will see.

MAKSIM (88%)
Is it head lock gyro?
   frebor (86%)
Yes it is

ketnet (67%)
does this gyro has a remote gain and so on? i'd like to use it on a trex 500 E

regards
   ppxav (83%)
yes you can adjust gain from your transmitter, you adjust end points on the gyro itself
cheers

kerim (79%)
I want to buy futuba 401 but it is expensive. This gyro works like futuba 401 or not.
Sorry for my english
From turkey

frebor (86%)
I believe itīs a Piezo gyro. Just another way of describing it. I just ordered one as a test.
   motorhead (87%)
thanks for the reply. I was really hoping it would be a SMM gyro. It looks so much like the Futaba 240!

do let us know your test results!

motorhead (87%)
is this a SMM gyro (like the GY401)? or only Piezo?
   dankers (100%)
No. This is a Piezo gyro as stated "Quartz vibration sensor".


lyclyc (59%)
can do invert funnel with this gyro?
i am sure it can do pirouetting flip as i can do it on my esky headlock gyro.

slumberjer (88%)
Basic and Intermediate 3D sure can..digital servo not supported. Performance wise gy240
   ppxav (83%)
sorry to interfere but digital servo are supported, probably not every digital servo, but mine is perfect with it..
regards
   Southbend (89%)
Yes correct! I burnt one up, it was a Spectrum 75, smoked it immediately.
