maybe my skills have caught up...or lack of skills made me not notice but lately I am really starting to be dissappointed with the G90 gyro on my HBK...it just constantly drifts...the tail servo is always creeping...I'll spend a few min at the beginning of a batt and get it set right...then half way through it starts drifting again...when I swap in a new batt I have to start all over....Now that I'm doing some more advanced stuff I want the tail SOLID...the LOGITEC 2100T on my MINI is awesome, holds perfect....I want that on the HBK...does anybody out there have any tips or tricks for the G90 that I'm not aware of????..if not, SANTA may have to bring me a new gyro...I'm also thinking the tail servo may be dying a slow death...may have to swap that out for a test

Welcome to the G90 sucks club

Sounds like you're just the candidate for a new combo coming out probably around Febuary

http://www.hitecrcd.com/servos/show...3+digital+servo
http://www.horizonhobby.com/Product...ProdID=HRC41920

And likewise I hear Logictech will be coming out with their own matched servo for the 2100T soon too

My trusty ol' GY401 is still my favorite though which is likely going on a new Trex next week

I love my GY240

I've done side to side fairly fast and The tail holds like a champ I do loose a few degrees hovering over a minute or two you can get rid of it by upping the gain but then the tail wags. Its almost like it doesnt know what to do when theres nothing messing with it cause for FF its awesome stays where you put it But Im still using s75 E-flite servos. I never would of got into FF like I am now with a rate gyro.

the 401 has remote gain and works with digital servo but the combo is $230 wow. Hind sight is 20/20 But now I know I would of paid the extra 20 bucks for the 401 so I could use digital servo and have remote gain.

No Really I am the club President!!!

The $230 401/servo combo is for 600 size helis - You wouldn't want to use that behemoth servo on a 300 - A 3154 should be a good digi for a 300

One of the reasons I went with the 2100t was all of Micro's ranting about the G90 Don't worry, you weren't the only one. My first reaction to a HH gyro was pure shock. This coming for the stock rate gyro on the Blade, it was a whole new world of tail control.

Now that I'm hovering fine, I get bored and start staring at the tail. Any little wiggle and it grates on my nerves like finger nails on chalk. I went with the HiTec HS81 since it was fast and cheap. Not digital, but I didn't think I'd need that for some time. Now that my thumbs are more precise, I can start to see the weakness' in the tail. I suspect the servo is the weak link. I have a couple DS285 servos from the DX7 kit. I thought I try one out on the tail. Its slower than the HS81 but, its digital and perhaps more precise. Ultimately, I think I will need a faster digital servo. If I can get by with the HS81 or the DS285 until the new HiTec servo comes out, that's probably a good option.

I have no other HH experience so I can't compare the 2100t. But you already have a 2100t on your MT so you know what its all about.

What heli are you talking about? If it's a 300 the 3154 is probably best suitable - If a 450 the HS-5082MG should be out around Febuary for around $35 - If it were out this next month I'd try it myself on a new Trex but I can't wait until Feb so I'll probably be going with a JR3400G ($75) - Oh there's also the new 9257 which is .08 sec 4.8V only though

I have a HBK2. Gyronut had commented in another thread earilier today that he likes his 3153. The 3153 is a few dollars more but slightly slower than the 3154. Any ideas what the differences between these two are?

I don't know what the difference is between 'em but yeah you reminded me that people have been toasting the 3154s but not the 3153s - I don't know why that is - I guess the 3153s are the way to go instead

Alot of the guys were burning up their 3154's by running them at too high of jolts and they couldn't take it thats why I made the change to the 3153.

thanks for the replies guys...that new hitec gyro is a LOGITEC 2100T,they have a licensing agreement with logitec to make them...but that new servo for 450 and up helis is supposed to be ALL THAT.......its so funny guys are so brand loyal....I see posts where guys REFUSE to consider a LOGITEC gyro but are waiting patiently for the HITEC.....HELLO????.........I think if I do anything It will be to get a new LOGITEC(hitec??)for christmas...the one in my MINI has been FLAWLESS since the day I got it,I put it on months ago and haven't touched it,the tail holds like a champ..in all weather and for 105.oo new with warranty how can you beat it...now some new, small, fast, tail servos to consider???????

Careful....
I paired a 3153 with logictec 2100T thinking it would be more robust that the 3154, which it is. However, I am not sure the 3153 was meant to be a tail servo. Although it is only marginally slower than the 3154 I could not get the tail to hold with this combo. I switched the servo to the new s9257 and problem solved. Just an FYI, your results may vary, but mine were less than stellar.

I dont get it I guess either my flying skills are not good enough or a futaba gyro is just awesome. I love to punchout or make a quick movement just to watch how dang tight the gy240 grabs the tail and wont let go. Considering I'm using E-flite servo from BCPP I don't see how it does as good as it does. Why has no one even mentioned futaba gyro's especially you fender I'm a little disappointed?

BTW fenderstrat

The G90 seems to recenter itself each time it's booted up so rebooting when swapping packs starts it all over again - When it starts to drift you could land and reboot it but who'd want to interupt their flight a time or two to do that when you can just use the trim tab until the next flight

Real piece of junk IMO - I can't believe I actually flew with it for so long myself

Which heli was this on? Is the s9257 too big for a 300 class heli?

I think it's a bit big for a 300 myself (weighs same as 9650) - But I also think the torque is rather marginal for a 450 too unless you were to reduce the load on it with boss weighting

Here's some leakage on the new Locigtech 3100G servo for ya fender

Why has no one even mentioned futaba gyro's
Micro still loves his 401. For me having just recently went through the purchase decision here's what I found. The 2100t costs less than the 240 and has the features of the 401. In Brovic's 2100t setup video, he commented that the 2100t its "more advanced" than the 401 which is larger and costs $35 more.

At our level, any of the three gyros provide more tail holding than we need. So you can't really go wrong. Pricing, size, and your tail servo can be the deciding factors.

The one area where the 2100t seems to be lacking broad compatibility with servos. Even in this thread there doesn't seem to be consistant results even with thre same servos. I don't often see the Futaba owners with the same complaints. The one constant seems to be the 2100t really needs a fast, digital servo to work well. Which offsets the cost differential between 401.

Last night, I swapped out my HS81 for the slower digital DS285 and the tail wagging stopped. Go figure. I need to replace my tail servo, but with which one?

Gregor and Micro,
I was using the s9257 on a Trex. I was merely trying to point out I did not have good success when using the 2100T and 3153 combo. The s9257 (although bulky) is actually designed for use on 450 class heli's and works quite well.

Tyran,
I will agree the Futaba gyro's are top notch products, but I think the reason not many mention them here is that they are a bit porky for a 300 class heli. I think they are a little big for a 450 myself. Lighter is better in my book, especially with a heli of this size.

I personally have been very pleased with my $38 Esky HH gyro! For the money you can't beat it. It take a click or two of trim at the beginning of each flight, but once trimmed locks the tail very nicely.

I had the 240 from when I built my ECO8 I kept the gyro when I sold it so it was the right thing for me to do. I cant give an educated opinion of other gyros or gyro combos. My only experience is the rate gyro 3&1 of my BCPP and the 240. But after all these conversations I think I'm sold Ill only use futaba gyros.

The Futabas do seem less finicky about setup and servo choice than the 2100T - Even gets along perfectly with my direct drive system on my BCP whereas my 2100T holds it great in hover and mild aerobatics but not so great in 3D where it has a hard stop-&-go during piro combo moves issue that won't go away with any adjustment - And I think we're all realizing the G90 is just a drifty piece of junk - So I've been recommending people to either go cheap with an Esky etc or go all out on a GY401 etc depending on heli and preference

I prefer the logitec because its cheaper, smaller, lighter,performs flawless for me and I love the set up functions....I hate the limit function on the 240/401.......I'm gonna get another 2100 for the HBK and be done with it

the futaba stuff are great gyros(perform good/easy setup) I just prefer the 2100
The one constant seems to be the 2100t really needs a fast, digital servo to work well.
I have a 9650 on my MINI TITAN and it works AWESOME with the 2100.and the 9650 is a rather slow servo..I saw guys this summer doing extreme 3d with a 2100 and it didn't blow out no matter what they threw at it....one T-rex guy even flew mine TRYING to blow out the tail(comparing heli's, he was looking for any flaw) and he COULDN'T...since it has MORE set up options you just have to take the time to really fine tune it and it works well with all types of servos...especially the "rotate rate "function...you must take your time and dial this in with your servo and epa/atv settings to get the most out of it...I'm NOT saying anyone here doesn't know what they are doing but I think a lot of guys dont take the time to properly set up a 2100 which is why they aren't getting 100% of the performance they could

this was originally to see if I could pick up any tricks or tips with a G90...but its time to move on......hey...... my skills have finally outgrown a piece of equipment......cool
