Similar looking servos can be found on eBay and other asian sellers, 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!

fitted in my small glider and electric plane, do the job* RAS

I stripped some of these servos and made micro brushed forward and reverse ESCs out of them.

I'll try to post a video.

I need servos that turn 180deg to use on a tilt-rotor VTOL.

Have a look at "Turnigy™* TGY-R5180MG 180 Degree MG Analog Servo 2.0kg / 0.12sec / 12g" PRODUCT ID: 9399000001 or if you want to tweak the HXT900 to do 180 degrees (which I am not sure if it can be done) you have to start to add resistors to the two tips of the feedback positioning potentiometer. If you are lucky, the resistors may have the same value if you reach 180º*. Sometimes you end up with different value resistors for the servo to move 90º* to each side. I would use the metal gear servo for the wing tilt task.

Gotta say these are nice and smooth. I rebuilt two from busted ones I had tried to use on a tricopter (mistake, need metal gear for that) and they worked fantastic for my KK2 driven servo gimbal.

I also find these servos quite a lot with high satisfaction.

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

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.
