what I wanted to ask you, and am always forgetting to do, what transmitter/reciever system are you using?

That is what I do and I said this to clarify:

By controller I mean transmitter. I set the dual rates on the transmitter. I always set the max servo end points and leave them at that. So with my "Rudd Rate" at 0.6 (which is = to the 60% I am setting on the transmitter) I am getting small bounce. Its really small and isn't something I am bothered by. I just wanted to pass on the info that at "Rudd Rate" 1 I get perfect stops and at "Rudd Rate" 0.6 I get a little bounce. Maybe you can try this out and confirm the same thing is happening?

FlySky 9x with er9X firmware. Same as the Turnigy 9x.

OK, thanks. I will add this to the list of working recievers.

EDIT: sorry, I missed your second last post.
Thanks for claryfing the 60% rudder thing. It is interesting that you get a small bounce with smaller maximal piro rate. I have never done that since I kept my Rudd Rate always at 1.0. But I will try it for sure.
Do you see a difference if you set RuddRate = 0.6 as compared to RuddRate = 1.0 and a 60% dual rate in your transmitter?
Thx for reporting this phenomenon!

wau, I was just flying another 5 packs... and it may be that the stops are not absolutely perfect and it maybe that there are better gyros around... but I am flying since 2 years CP heli and had some configurations (tail servo/gyro) in test, and I stand to that, this is by far the best gyro I had ever installed (I don't mind if I will be the only one having this opinion ). I am going to sell my GP780, this is now darned clear to me

But that's actually not why I am writing. I can't fly backwards, but since some guys "cry" for testing the gyro's performance in long tail slides, I researched the web to figure out what this is, and thought that maybe that's a stunt I may try. So I did today. I can't of course claim that I can do nice long tails slides, but in few cases I could let the heli drop for easily 30m or even more (and in one case to almost crash ). Now, as much as I can tell, I couldn't see ANY indications that the gyro would not hold the tail. So, from that I am kind of convinced that it will also do it's job in such stunts.

Hopefully a better flyer than me will ever test this gyro. (HINT HINT HINT you have heard that, you flying cracks LOL)

Another point: my heart was really bumping and my knees where shaking due to these long tail slide tests... that's why I like heli flying... I am sure I will continue on practicing these tail slides, they are fun LOL

Thanks for the feedback, i'll wait for the next firmware upgrade, hopefully by then the bounce will be totally eliminated.

cheers

Maybe I am not doing things right or maybe my setup is at fault. We really can't tell exactly how this gyro is performing by just a few people testing who can't even fly 3d. If I were flying these for longer and had better gyros to compare to then that would be fair. But I consider myself a beginner. I don't conclude that my testing or reporting is as accurate as someone who is not a beginner and has knowledge about testing gyros on helis.

I'm just saying that you or someone else may get different results than I.

ahh I see what you mean. I'm waiting for Holgib to test the gyro out first with a couple of long tail slide video. I gotta see if this gyro is worth all the trouble in configuring and installing. Once I see a successful video I will proceed with the assan ga250 olliw firmware, and start with some tail tests and hopefully some 3D manouver ie: piroflips(to check if it has a constant piro rate etc).

pitchp,
this gyro project is most likely nothing for you...
you are always waiting for others to test the next firmware for you
you are crying for people to spend their time to produce videos to save you time
you are crying for people to risk their helis in doing long tail slides but you can't fly them yourself (if I am mistaken, there are YOUR videos?)
frankly, if you are not willing to spend a minimum amount of time, then this project is simply not the right thing for you
IMHO you are certainly better of buying a commercial one

this is what i was wanting to hear. i have no problems buying equiptment to make something work but then if the results arent there (aka the program parameters )and it crahes , then between all the programming hardware and time i could of just bought a quark .
i am with pitchp , let others crash before i test something unproven

well, all people who have used it so far have not had a single crash because of the gyro...
some even report that it performs much better than anything (cheap) they had before even in version below v0.16
but YOU will never know, and your claim that the results are not there is a pure claim
you don't even know about what Rob is talking, how wposisbly would you, hugh?

try it, test it, and O N L Y then you should make any claims as to its performance

but somehow you guys seem to know everything without even having any clue
what is is your problem? if you are not interested in this project, no one forces you to participate. So don't do.

As I said, you are certainly better of buying a commercial one.

Um die ecker bringen?

Come on OlliW, let's just keep this thread on track - you guys are doing great work, and there's no need to get involved in a flame war.

For all its faults, everyone has to admit that the GA-250 has opened up new possibilities for enthusiasts such as yourselves, to turn a low-cost, good value but somewhat basic gyro into something that can compare favourably with far more expensive name-brand products.

It's inevitable that most users won't have your electronics skills, so you are bound to be the ones doing all the heavy lifting on this project, but that simply does you great credit. So just keep on with it! (and do FBL controllers next!)

Come on 2Doggs, I think to have clarified that judgements about the performance/reliability of this gyro by folks who didn't even had this gyro in their hands and even less in their heli are not appreciated will help to keep this thread on track

THAT's perfectly fine, and wouldn't be any problem! Anyone with an interest in this project AND a willingness to make a serious effort WILL get here the help she/he needs.

Some users, i.e. HolgiB and scottyvisco, have in fact already put together some very usefull info which should provide a good start.
