WARNING
These servos can be found on eBay and other asian sellers at close to this price, however be warned, they do not contain Taiwan/Japan components. HexTronik (the manufacturers of these servos) have two standards, one is for local sale, and the other is export quality with imported connectors and resin gears from Taiwan and Japan.
Our HXT500 and HXT900 are export only, and not built for the domestic market. You will not find the same quality servo for less, anywhere!

Does this include linkage stoppers?
 EstebanT 697 points
Hi Joshua. No, it does not! It includes one servo with cable and JR/Futaba plug, three servo arms and arm screw, as shown in the pictures. Best Regards!

Joshua what is a Linkage Stopper??? You get all the accessories in Pic2
 EstebanT 697 points
Hi NewToHobby. Linkage stopper is a small device that mounted on the servo arm allows you to fit and set the pushrod end. Examples: Product ID: 1) 016-00503x10, 2) OR016-502x10, 3) OR016-00501.

Hi Esteban. I suppose they come with pushrods
 EstebanT 697 points
No , pushrods are not included with servos. You want to select among a wide variety of types and sizes depending on your model characteristics and requirements.
 NewToHobbyKing 14738 points
Well " Linkage Stopper D2.1mm (10sets) " (SKU: 016-00503x10). I have bought them and used them but never noticed the NAME! Thanks for the lesson! (It seem HK sells the separately)
 EstebanT 697 points
U r welcome! Regards!

Are these the same servo as the Tower 9g servo you see sold on ****??
 sisman 28 points
No, these are Hobbyking's version of them. There IMHO about the same quality.
 RonRC 3899 points
I've torn these down and torn the TP 9g down and the inner workings are virtually identical. If I ever get another TP 9g, I will look closely at the control board and compare it to the HTX900's board to see if they are the same. I've found ESCs that are identical that wear different labels but other than that are exact matches down to the smallest chips and where they are located on the boards. However, in some cases one ESC may cost 2x, 3x, 4x or even more than another.

love them! cheep but work!
 RonRC 3899 points
Yep! I trust them on my flat foam F-22 that hits close to 90mph.
 NewToHobbyKing 14738 points
They are great unless you crash. I have found that used normally, this little servo is mighty, but the shock input, of a crash, seem to break a tooth of the same gear! So if you are like me and always land harder than you should, then do a surface movement check, before every flight! HKR! (Hobby King Rules!).
 RonRC 3899 points
Only thing I've had an issue with is using these on a tricopter. If you only plan to fly around, they should work fine. But when doing Acro, you WILL crash and on those occasions if the tail boom hits first, it will strip the gears. I don't think there is a better servo in this price range and there are some that cost much more that are not as good as these.
 NewToHobbyKing 14738 points
RonRc funny you should say that. I picked up some metal geared servos for the same price (Four Dollars). (Once you allow for postage).
 NewToHobbyKing 14738 points
Also, as I crash less (just flying around), I do fine these servo are fine for every day use. (Hay anything can break in a crash).

One of the best and MOST HOT selling servos... These come into stock and within 3 days are again out of stock... HOT SELLING Item. The performance of this servo is extremly good and fast. Very accurate and there are no centering issues. The gears are resin/plastic and for the money totally worth it.
I have been using these on my foamies for a long time now. A bit noisy but torque is good. Highly recommended. Buy them before they go OUT OF STOCK AGAIN.

These gems are fast and strong, a bit noisy perhaps.

There is a downside of beeing strong and fast, they draw quite a bit of current.
I measured about 550mA when exercising one HXT900 without load. This is an average, it seems to require more peak current. If used together with a linear BEC it will cause voltage drops.

I tried 2 HXT900 with a 1.5A BEC and a Spektrum AR6200 Rx. I could not exercise those two without loosing power to the Rx and cause it to a "BrownOut Reboot".
With four servos connected, I could not even touch the control stick. The BEC circuit also got so hot it melted its plastic sleeve. Still works though, did not fail completely.

I tried with a larger ESC, having a 2A linear BEC, and it worked much better. But I could still force a "brownout reboot" by wildly excerise all four servos. I dare not fly my Pitts this way.

So, with four servos or more and an AR6200 Rx, I think you must use a larger switch mode BEC capable of 3A at least.

This is a combined problem of high current surge, poor power supply and voltage sensitive Rx. And maybe poor filtering of the powerline.
Not really a problem with the servos as such.

Alot of flyers in the area are just loveing these. Similar, and in some aspects superior performance to the famous HS-81 at one quarter the price.

Here's some stats from the forums here at Hobby City:

Results in degrees/sec.:

@4.8V 450
@6.0V 560
Results in sec/60degrees.:


@4.8V 0.13

@6.0V
0.11

Torque Centering
1.3 .2

These HC babies kick Hitec HS-65HB's into the weeds starting with a massive 6:1 price ratio saving and ~identical physical size26.8hx23.2Lx12w mm at 9g. They use their own horn spine type however and good quality copper servo wire, and make a similar noise. My tests show very slightly higher power drain than a HiTec HS-65HB
@4.8v smooth flying/hard reversals/stalls @/speed
HXT900 160ma/290ma/690ma/0.14-60° (side-by-side with Hitec)
HS-65HB 135ma/260ma/545ma/0.14-60°
I have bought more than 30 of these and never did one give a problem with normal park flying/crashes and they work fine at 6v but be aware the current will rise to 190ma/370ma/690ma for your BEC. This servo allows you to own and operate 6 models where Hitec would limit you to one model. You decide. My recommendation is get more for less - they are basically the same spec. Sure we all have a few models that we like to run expensive servos on, but these HXT900 are the base to build a big pyramid on, and spend the money you save on buying more airplanes and helicopters. I don't consider them anything like a HS55 which = HXT500. 5 star performance for a 10 star price.

These are really nice servo, and you get seven of them included shipping, for the price of one in Portugal.
These servant are fast and very accurate, and the price is fantastic.
Five stars.
