Question: when the bird is idle with battery on it, do you see any jittery/shaking on the servos? I am having these issues on the 5 servos I bought, even connected to a servo tester. Thanks guys!
 LasseK 1752 points
What kind of bird is it? If it's an airplane, are the control surfaces jittering? This may happen if you have a low-friction mechanism and there is some play in it, or the surfaces are simply to heavy for the servo to hold. You might reduce the problem by introducing just a little friction in the hinges. If it's a heli, then the servos really shouldn't jitter. But if they do, I would use an oscilloscope and check how the voltage to the servo looks (the BEC may be overloaded). How many amps is your BEC rated for? HTH
 Leonardo 54 points
Hi mate! It is an Align T-Rex 450 Pro. I use the stock ESC, but not sure how many amps the BEC is. But as I mentioned before, the servos jitter even connected to a servos tester only (no ESC involved). Perhaps there is something to do with the metal case (interference)? Maybe these is something to do with the servo gears not have enough grease? Thanks
 LasseK 1752 points
These servos require more power than the Align ones. I would use a stronger BEC instead of the one built-in into the ESC. I use this one: 9171000496-0 (Q-BEC 10A). It's not really a 10A unit, but it copes well up to 9A (measured, refer to picture "BEC comparison" under the FILES tab on the Q-BEC product page). This modification is recommended irrespective of any jittering, to make sure you have enough power to the servos, and to avoid receiver brownouts. But back to the jittering. Do the servos actually move their arms back and forth visibly, or do they just "hum" in a solidly kept neutral position? Because the latter is normal for good servos with a tight deadband. The humming only means that the servo is holding its position tightly. If you try to move the arms you should hear an increase in the humming, and when you release pressure, the humming should subside again (but it will not go away, and again, this is normal). HTH

Yes, the servos actually move back and forth visibly ( /- 0.6cm) each jitter every now and then (~30 seconds). They seem to try to find the right position or something like that. They do hum, for some seconds and then suddenly jitter without any input. I have done the circuit board insulation before turning them on for the first time. When I apply pressure to the servo arms, it hums louder and when I release, it comes back to normal hum. I will try to record a small video tonight showing this. Any more ideas?
 LasseK 1752 points
Do they behave the same way on the servo tester even if you only run the test with only a single servo? Do you power them with the align BEC when you do this test? Are you really sure the BEC on that ESC is OK? Can you perhaps test with another BEC, or maybe a 6V battery (so you can rule out the BEC as a problem source)? Have you checked inside the servos to see if there are any shorts? Some users have had problems with that, solved with a piece of insulation tape (search in the reviews for "short" after clicking "click here to view all reviews"). HTH

I see reference to the head screw size to be M2.3x.5 in the discussion below, but I have found no-where to buy them (HK or otherwise). Anyone able to provide a link? Thanks
 James 435 points
try your local hardware shops, these screws may be common

Eh, I lost my question. Let me repeat. I am looking for its arm accessories and found out that its accessories titled kst 115/215 servo arms from helifreak forum. The only accessories I found is this: https://alofthobbies****/kst-ds115mg-ds215mg-g
ear-set.html and
it seems that the connector is a gear instead of gear hole. Can anyone advise me? Actually I am looking for: mounting accessories arm accessories to make the output a gear with module of 1. Thank you!
 James 435 points
Have you tried moulding your own arm? and customise it? seems like a good idea
 Agustinus 2 points
*James, thanks for the recommendation. I tried to come to my local manufacturer company and they can't make it because the hole will be to small. Also, the item in the alofthobbies link is wrong.

try this one

How many teeth must have a servo horn for this servo??
 ghostW 11 points
you can use hitec arms for this servo

is there a way to get replacement gears for these?

Arrived boxed up and with full accessary set. Good length on the lead. The case is well finished and looks good. There is zero slop in the gear train and the output shaft is free form wobble. The whole servo feels solid. The servo is fast on my servo tester, and basically I cannot fault it. I will be putting this to the test on a 450 tail, I figure it would also do equally well on a cyclic set up.

Цена этих серво машинок просто замечательная, относительно других производителей! Что то подобное видел по цене не ниже 30 долларов. Думаю качество не будет на высоте! На наклейке написано, что сервы сделанны в Тайване, возможно их производят на том же заводе, где выпускают сервы МКС, например DS95, но в серве MKS DS95 используется немного другой редуктор по описанию, там стоит титановый, здесь же описано, что редуктор металический, не думаю что это полная копия! Как придут дам более полный обзор. Я их покупал для 450Про вертолета с безфлайбарной системой, для управления ротором.

All gears are metal (some looks like aluminium, some - brass, and main gear is a bit different color as other aluminium gears, probably different alloy). So far so good, very quiet, no slop (well, compared to 3 other 20-30$ servo i have here) and very very fast. And by telling "fast" it's not only numbers (for example, prod id 14279 "on paper" has the same speed, but on tester looks like turtle compared to 306G). I do not fly heli, so can't tell where it could fit or it could be easily stripped away (like someone told in discussions tab), but i'm going to use it in very fast wing. Overall - very good quality, and good price. Will buy more.

pour mon futur 450, mais j'ai pas le temps de le monter maintenant, donc pas de review pour le moment, mais rien qu'à les voir, je suis sur qu'il mérite 5 étoiles.

So far so good. Works great on tail of an older 450 v2. Really wish it came with a round horn as well. I have read about stripping the metal splines on a crash so I notched the horn just a little hoping it breaks if I ever crash. It's quite heavy for its size - but lighter than the mini servo I was using before it by just a few grams. But for cyclic I think you would be weighing down the heli quite a bit. Might be worth it though if using a FBL setup.
