And what are the odds of ALL 3 "DS" servos failing exactly at the same time?? This would be a new spin on Murphy's Law.
Does not mean yours are bad. Mine are. If they are steppy and chattery IMHO I would say they are bad. I didnt say they would fail. I said they were impossible to set up properly, therefore will not get used.
Your bad experience doesn't equate to everyone else. Fine....you have bad servos. Does that mean the 3 DS 610 and the 4 DS 620 are all bad?? Should I return them before I totally lose my heli's??

How about everyone else that owns Align servos, should they return theirs as well??? What about all the problems with JR or Futaba?? Should we quit using them as well??
I certainly NEVER said "because mine are bad yours are too". If they behave the way mine do I would say YES they should all be returned. Let Align know shoddy electronics for cheap (even though specs are good) will not be tolerated, as with any companies product.

And believe me, if I ever had a Futaba or JR servo behave like this I would most certainly say so. The good thing is I am not sponsored say I CAN say my experience with this stuff.
Should I return them before I totally lose my heli's??
Your call. I dont tell ANYONE what to run. Its your money, not mine. If you are comfortable with them, enjoy..

just butting in
ive got the ds610s running direct from a 2s lipo for the cyclic and regulated 5.2v ds620 for the rudder.

my cyclics does glitch on the bench.. sometimes just one sometimes all three. but i read sumwhr its because due to the high speed and voltage the electronics try too hard to find the centre and they overshoot. do not quote me.

once (just once out of maybe 50 flights) during a flight the cyclic went slightly haywire just after taking off for a hover. landed, cut engine, off and on tx/rx, restarted and it went away. never found out why though.

as off tonite, the ds620 coming off and will be replaced by an old 9253. it just wouldnt stop wagging no matter how. crashed hard last week, boom snapped in two. guess the 620 was hit hard. no physical damage to the exterior or tell tell signs of stripped gears.

im keeping the 610s on because 1. ive got no more servos 2. apart from dat 1 incidence, or on-the-bench glitches, they performed 100% no matter how hard i push them. 3. its on my practice heli so if it crashes (again and servo beyond economical repair) i have an excuse to buy n try the new savox/align servos that i heard is coming soon. hehe

Geewiz, never thought my simple comment will bring the blood to boil, look, what i meant is sometimes servos may sound weird and may look weird but when you fly they work extremely well. My 8717's "glitch" on the bench with the ar 7100 rx, lots of people have experienced this but seems it does not glitch in flight, perhaps the rx is too close to the tx on the bench who knows.
Good thing is we are all entitled do do as we please so if you want to throw out your aligns for something else good for you, my comment to go fly and not worry too much about behaviour on the bench is based on personal experience where bench behaviour does not neccessarily relay to flying.
One thing though i guess it's important to look at alternative causes that may cause steppiness, for one the rx resolution may be too low, for instance on spektrum ar 7000 resolution is half (1024) of ar 7100(2048), the higher the resolution the smoother the servo, obviously if the servo is matched. It would be interesting to get some data on type of equipment that relates to steppines.
Baddraptor what radio setup, regulator etc are you using, maybe we can find a tendency or compatibility issue here.

9303 2.4, 921Rx, Scott grey Reactor reg, 3600mah lipo. It isnt and equipment issue IMHO. I run the same set up on all 3 of my 90s. Pix are in the gallery as far as electronic placement.

If its an incompatability issue, almost everyone would have the same complaints. As I have said in previous posts, I know Savox makes GOOD servos. I have used them in the past on a couple planes. I am certainly not new to RC been, flying for 30yrs (4 yrs heli). I have had bad electronis before, it happens. THese are bad (my set).

Didnt get my "blood to boil". It was a weak comment that sounded like "dont bother to do a proper set-up, just fly". I am a perfectionist that likes to know about interactions and set up issues. I can get rid of any problems before ever flying. Never had an isse like this with ANY servo in all the time I have been flying.

I agree with you Stolla. It is my choice as to which manufacture I use, good or bad. I wanted to try the Savox/Align servos because of price, speed, and torque.

So far the set I have is working fine. Yes, I too have noticed a servo glitch on the workbench, could be due to working too hard or the type of receiver (AR9000). But this hasn't stopped me from using them.

I would like to see if these servos will become the alternitive to the over priced named brand. Let's face it, $200.00 for a servo that can run on a fully charged 2 cell LoPo (8.4V), with no regulator??

I guess....if you have that kind of money to throw away, why not.

I've had 5 flights so far on my Trex 700N with 3 Align DS610 on the cyclics. Due to a Dean's connector failure, my 700 crashed. It's almost fixed, and should be ready to test fly tomorrow / Friday, providing it doesn't snow......again!!!

I think your misunderstanding my issue with the servos. IMHO a glitch is an intermittent twitch or so that happens OCCASIONALY. mine is a CONSTANT severe "notchiness" in the range of movement in the servo. It made set-up totally impossible. I could not even check for max pitch or cyclic without the servos (all 3) moving at least an 1/8 of an inch up and down. THey do this at rest or when moving the sticks. IMHO the set I have is totally unflyable.
I agree with you Stolla. It is my choice as to which manufacture I use, good or bad. I wanted to try the Savox/Align servos because of price, speed, and torque.
Your right. And I have said as much. But at the same time, in your first post, you asked for experiences good or bad with these servos. I posted my bad. In a thread asking about stuff like this, They take on a life of there own and doesnt always follow simply the OPs question. Sometimes they start following others experiences ad this one has. So dont get upset with a semi high jacking as it is STILL about the Align servo, just not only yours.
..if you have that kind of money to throw away, why not.
LOL, if I did not have "throw away money", as in money that cannot be spent in much wiser ways like true investment, I would not be in this hobby.

Baddraptor, just to rule out any compatibility issues have you tried using a std 4.8v nicad instead of the SG regulator?
Btw if you described the steppiness at first to be so severe that you can't set up pitch and cyclic i wouldn't have made the statement that gave you the impression you should'nt bother about setting up your heli......or whichever way you want to read it.
So who else has this problem with the align (savox)servos. The fact that they provide the option to get 8717 performance at a fraction of the cost is the real attraction but if there are problems or compatibility issues it would surely help to be aware of them. It's not about throw -away money cause if you do you won't have any

rcnut what's with the dean connectors, it's not the first i've heard of, could you explain in more detail.

I'm at 150 flights plus with the DS610's and there are no issues.

Brushless 8v servos are not that far away now either.

I tried to make an "Arming" switch, like that of MPI's (before I knew MPI had an arming switch setup). Only my arming switch has no wires other than the jumper wire to turn on and off the heli.

I took two Dean's, male and female, and clamped them side-by-side in a vice. Then soldered a third, female Dean's, to the other two, making this a very ridged connection, allowing for no room to move.
This was probably my first mistake. Had I used some wire, like that of MPI, this problem would have never happened.

How I was able to get 5 flights this way is beyond me. This time I ordered an Arming switch from MPI.

This whole problem started with trying to make some type of on/off switch. I used Fromco's Sahara regulator instead of the Arizona. The Sahara doesn't have an on/off switch connector like that of the Arizona.

I have been flying 620 on my 600NP cyclic and I must say I am impress. They replaced 8717s and did just as well.

I will be putting together my 2nd 700 in a month and using the 610 servos. My 1st 700 has 8717 so this should be a good comparison.

Reading this topic post did give me some added confidence.

Thanks

You just said they a bad set also,I'll give you $17

If they are bad again as you say I would take them back on the heli and show them and make sure I get the money back.

You sure got some bad luck with them.

I put a set of 610's in my T700 last week, replacing a set of S9451's as I was suspecting my elevator servo was loosing center.

They were drop in and fly on except for the few clicks of subtrim I had to remove on the elevator (which was already suspect) and some de-tweaking in the linkage compensation menu. After going through a lot of setup in the linkage compensation menu originally for the 9451's, I found I had to remove most of it for the 610's. (I am not Futaba Bashing I love my 9451's) But I was very surprised to have to take out any changes here, I really would have figured it was configuration not the servo that dictated this settings. Anyway the changes made brought it closer to zero than the original 9451 servos in the airframe.

I read this thread a few times before I ordered them but thought what the hell they are inexpensive enough to at least try. I will tell you this for bench performance they are a hit. I don't have any stepping or notchyness they are smooth as butta! I put on my swash leveler and setup for center, had to remove some elevator sub trim.. I then ran it to top and bottom noticed I had some air on the Pitch servo arm at top, 2 clicks EP adustment there and no discrepancies at the bottom.

Put the head back on and pitch throws were exactly the same so no changes there. Took it out flying it performed flawlessly, No issues, no real changes other than they are slightly quicker than the 9451 and amazingly I could feel it.. I wouldnt of thought that I could but it was evident.

Now with successful bench run and a flights on them I was trying to think what would cause a notchy servo movement.. Bad servos for sure, but two sets of bad servos is hard to get unless the whole line is bad and mine are not notchy so whole line is not bad.

I ended up trying a few things to replicate a notchy setup but it wasn't easy to duplicate. Because I have them in a T700 and on the QUK servo wheels I could not easily mess with mechanical advantage, if someone is using their own wheel dimensions for another airframe and has the "notchy" behavior please post ball to center measurements so I can try to recreate it there too. So anyway, I dove into the radio and I found only one way to make my servos semi-notchy. If I increased the end points above 130% of servo travel and decreased the pitch percentage in the swash menu I could cause them to exhibit some steppy behavior. Especially when near the top or the bottom of the pitch scale and adding either elevator or aileron. But that is the only way I could make them notchy. As soon as I put the endpoints back to 100% (except elevator was at 102% for top of swash travel) everything returned to normal and there was no notchy behavior in the servos. I can go fast or super slow and the servos simply follow my stick movement.

I can easily see myself loving these 610's if they stand the survival litmus test for longevity. Especially for the price, if they wear within the same experience as other servos I can see these being my new very fast friends..

Oh last thing I forgot all of the testing was only done at 6 volts.. I dont run at 8 volts so I couldnt help ya there.

Wow sorry to hear about you're bad luck with the servo's Baddraptor. I just got my 2nd set installed and no issue's they are really good servo's.

But you never know when you'll get a bad batch.

I'm running unregulated about 20-25 flight so far on the 1 set. I just finished my 2nd set install so no time on them yet.

I wouldn't mind trying out the upper line Hitec's on 8v. I'll have to pick some of them up and give them a shot.

I don't crash... I land with style

the problem isn't whether that are a bad set of servos or not.

Its gotta do with the compatability of the setup. It probably doesn't like a certain setup eg. Spektrum VS FASST or 1024 VS 2048 resolution.

If thats the case, what should I change?
It is on 2048 res. x9303tx with Jr 921 Rx. I have tried 6v, 6.8v and unregulated.
I have tried Ar7000, ar71000r, and 921 recievers. In order to change anything to suit a servo, its going to cost more than the set of servos themselvs.

My endpoints are all at 100% with 0 subtrim and swash menu at 60. I am out of ideas for these things. I have already put the Ace servos back in and she is perfect once again.
If they are bad again as you say I would take them back on the heli and show them and make sure I get the money back.
Would love to do that but they are mailordered..
