The ? was which is better. The 8717s are by far I have owned both i hered the the 620 where as good so i bought them and they arent!!! that is not to say that they are bad servos because at $70 they are good servos but they arent as good as 8717s!!! And jr warr support is the best in the heli market!!!but if you arent into hard 3d most people wont tell the diff.
Sorry to pick on you dude but again you make a statement with no qualification....just that the 8717's are better.....better at what?
If you say that they are faster or that they hold better or at least something to qualify
but they arent as good as 8717s!!!
We have all heard the 8717's are less noisy but use more power. Have you had any of the align ones break? Do they have more play? Do they not centre correctly?

I am a JR user but looking for new servo's for my trex700 and looking at this thread for useful information for a servo replacement and so far I am thinking the align ones may be worth a try.
So if you could qualify your statement I think it would be appreciated.
Cheers

I have the 8717's in my rappy 90 and the 610's in my rex600. They are both pretty fast as the 610's are on 6 volts and the 8717's are on 8. For the money the 610's are great. I have not had any problems with them not centering and they get the job done for what i am asking of them. Mild 3d and what not. The 8717's are great in my 90 but I could not justify the cost to put them in my 600. If you want a good servo that is fast and not a power junky then go with the 610, If money is no big deal then get the 8717's. Plain and simple, no one knows how you fly better than you so it is ultimately up to you as to what servo you want to use in what heli.

probably the most important aspects are

1. longetivity/reliability
2. operation
3. centering
4. speed/power
5. gear play
6. power consumption

If all the above are satisfied and 98% of pilots couldn't tell under flight conditions then it makes sense to at least look at the cheaper align offerings.

I think we have covered no 2,3 and 6. 4 is there for everyone to see.
Noise has been covered.

So how much gear play does the align servo's have compared to the 8717 and has anyone thrashed these align servo's hard enough to cover point 1.

I fly 610's in a Trex600N with OS70SZH. I bang the sticks pretty hard on that bird and am completely satisfied with the performance. FWIW

They are as tight as anything else I've seen. Rumor is that they are titanium gears. Dunno if that's true or not, but they are tight, smooth and have 0 backlash. As for longevity, I have no idea, they haven't really been out long enough to tell at this point.

Also, just to go back to this:
but if you arent into hard 3d most people wont tell the diff.
I'd LOVE to see something that you can't do with the Align servos that you can with the JRs. I guarantee that there isn't a single thing that one can do that the other can't. The only people that might notice the difference in flight between them when run at the same voltage are the FAI/F3C guys. Of course at 8v that 8717s are noticeably faster, but even then I'd bet that there are less than 1 in 1000 people out there wou can exploit those increased capabilities.

Guys

Check out youtube.

There is a video on there for the align ds620. It was tested to destruction. When striped the gears look brilliant.

Do a search, its worth a look. It convinced me to go and buy. I am now installing 620s in my Trex 600 snp.
Interesting that some are using the 610s rather than 620s on cyclic.
I figured at 6v 10KG of holding power was more than enough and they are slightly quicker, not that you would notice that.

Be interested in your thoughts why you would favor the 610s over the 620s

Hi Helinutz,

I wrote that on rcHeli Resource. Just to clarify, the Hitec servo I was referring to are not the DS610 OR DS620, but the 7975hb.

I believe the DS610 and DS620 are savox servos rebadged and I believe the rumour that they are savox servos was started by that article. I have no proof or evidence about that, which is why I said I was not very certain about it.

Saying you wont be able to feel the difference between the 8717 and lesser servo's is bullsh!t,you dont have to fly as good as Alan or Jason to feel the difference. Maby a newbee might not feel or know the difference but anybody with with a little bit of time can easily feel the difference. Ar they worth the extra price,thats up to the person who is paying for them and how they want their heli to perform.It's not a matter of can you feel the difference.it's a matter of whether you want or can spend the extra money for them.

Yes, I am saying that if you take 2 servos that have very similar specs like the 8717s and the 610s, you are not going to notice the difference in flight. It's awful tough to see those labels in the air. Just because JR's marketing says "Feel the difference" doesnt mean that you will.

I would hope that 17 years of flying helis might qualify me to "feel the difference" But for the life of me the only place I can feel it is in my back pocket when I sit down.

What a laugh
If you really think that Aligns servos are just as good as the JR servos you either A) have been living in a cave the past 20 years or B)You just got into this hobbie and don't know any better, which I hope is the case. JR has been making servos ohhhhh.....I dont know, since the beginning of RC planes, cars and helicopters. And Align has been making what over the past 20 years? I wouldn't put those servos in my helicopter if you paid me to.

the align servos are good but the 8717s are great the 8717s center better, are faster, dont move like crazy when they are stalled, can be run on 8v and have a FULL 3 YEAR WARR!!!! alot to you just want to hear what you want i own both of them as i said before the align 610s are good for $70 but they are not the same or even in the same ball park I can feel a huge difference while flying hard 3d that the 610s dont center spot on and you have to correct more in flight also when setting up my 8717s are no more then 2% off in my travel %s and the 610s are 8% for the 3
Once again i am not saying the 610s are bad they are the best $70 servos i have flown but they are no where near the 8717s

OK, from a specs standpoint the Aligns look to be more than adequate - fast and plenty of torque. If you all say they center well and have little slop, I will take your word for it. After all, a servo is nothing more than an electronic device. It either does what you need it to do or it doesn't.

However, how long will they last? And if/when they break, what kind of warranty service are you going to get from Align? Certainly not as good as you'll get from Horizon.

For the price, I may give the DS610's a try. Though I will probably wait for the brushless version to come out. My 8717's are the last standard size servo with brushed motors I bought except for 2 throttle servos. I think Futaba is on the right track with the BLS series. I have 14 of them so far. When are the other manufacturers going to step to the plate.

Servo
Well I guess its ok to put a cheap Align servo in a cheap Align helicopter, but I wont be running to the store to put these in my Stratus thats for sure.
