These servos can be found on eBay and other asian seller stores 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.

Because we order direct from the factory in large batches, the servos can sometimes be red, blue or green, depending on what our wholesale customers requested. Do not be alarmed, the colour does not indicate that it is a different servo.

does anyone know what servo horn spline these are?? I want some really long doubled sided arms to work the ailerons on a foamy and the supplied ones are too short for what i want. WHAT SERVO HORNS ARE YOU GUYS USING WITH THESE????
 MTL_Greg 108 points
Use the supplied servo arm and glue or screw a popsicle stick on top. Then it can be as long as you need.
 MTL_Greg 108 points
But if you need to use a longer arm than the longest one that is provided, this tiny servo may not have the torque required to counter the increased leverage.
 gixerfien 29 points
sounds good, do you happen to know what spline they are thought, even for just replacements

um I bought some of these about 3 yrs ago. And now I tried them and 2 of them are dead from just sitting there...which I think is unacceptable. They were kept indoors. ( a third had stripped but I didn't think that was so unusual) One was in a plane that was unfinished. The other had been working the last time it was flown 16 mos ago or so. Now dead. Maybe something corroded, idk what would do that. but I won't be buying these again. Some turnigy 5.5g I bought are still working.

I built a 30" lightweight flying wing on the weekend and used these servos. They are working great on it. I usually use the 9g HXT900's, but for this wing I wanted to keep it as light as possible.

Thanks for producing and sharing this video! I will try to make one of those wings soon with some spare parts I have on hand. Is it better to use more expensive foam board (like the one sold in hardware stores) or dollar tree foam is the best? Mine will be slightly heavier wing as the motor and esc I have are bigger.
 JohnnyCanada 112 points
This is a very lightweight wing. If you are use an ESC and motor that are a fair bit larger you probably either want to go for 1/2" XPS (pink or blue) for the top step...or double up on the Dollar Tree foamboard. I've used a single sheet on the bottom step with motors up to a 2826/6 200kv with success.
 Bobo22 6 points
Thanks Johnny! How do you determine the size of the wing, prop size, motor size, lipo ratings on a scratch build? Is there rule of a thumb for it, or one can use whatever parts they have?

Buy 4 servos. Arms & screws was included only with 2 servos.

do these work straight of 1s lipo. 4.2~3.5volts, going to use this for dlg
 Gerry01 4398 points
No, it will work bad. Voltage has to be 4v or more.
 (Mike) 621 points
by bad, you mean less torque or continuous jittering, poor center etc
 (Mike) 621 points
I will be using this on a dlg and don't need more than .2kg of torque

Use with "TURNIGY Voltage Booster for Servo & Rx (1S to 5v 1A)" PRODUCT ID: DMDL-VBoster
 Gerry01 4398 points
It'll be jittery and as battery voltage drops, centering will not be consistent. I had one of this in a small electronic device feed with 4.8v batteries and, as voltage droped, servo became unstable.
 Gerry01 4398 points
Thanks for the credit!
 JayCUk 11 points
I have used these on a Nanotech 600 1s and had no problem at all. No voltage booster, in the 1000mm composite dlg. Needed nose weight so put in a voltage booster just to bring weight forward. I do no agree in "waste weight"
 MTL_Greg 108 points
In your DLG, use 2S power with a separate UBEC. Then everything will work just fine.

I think it is the best servo in this price and weight range! They are really fast and without problems to use!

Super Servo! Sehr schnell und eine super Rückstellgenauigkeit! Benutze für Servos in dieser Größe nur noch die HXT500 und bis jetzt ohne Ausfall oder irgendwelche Probleme!
Sehr zu empfehlen!!

These are basically TowerPro SG50 servos.
Their characteristics is quite good.

plus no play (dead band). Not even mechanical (teeth wag) nor electrical (by off-tolerance el. components in AA51880 ref. design)
plus highly accurate (results from the above)
plus fine-stepping (highly suitable for micro helis)
plus fast movement (.10 sec/60deg/4.8V), which makes them perfectly suitable even for heli rudder servo applications
plus weight. It is a bit above the spec about 6.5g incl. the connector wire
plus durability
plus withstands quite high load compared to its size

- their servo horn shafts are placed somewhat more to the middle of the servo face, which means that slight collective non-linearity may result with heli's eCCPM heads, as most designs need the horn shaft positioned closer to the servo upper bottom. However this is becouse of larger horn shaft gear diameter, which results in higher load handling (that outweights this flaw very well).

Money very well spent.
These are by far the servos with the best price/performance ratio I know to date.

Perhaps the best server ever for models with weight below 500 grams:
1) Very light (it may weight a bit hevier but you can handle it by replaycing the wires and drilling holes in it)
2) Very cheap (please show me a server on the market with the same parameters and with a less price - unreal)
3) Very good quality (it IS precise, smooth and well centered, best if used in foamies under 300gr. weight
4) Need more? I once was out of servos and given an HXT 500 by a friend - from that time I order only them and HXT 900 for my hevier models. Oh, by the way, in Russia this servo would cost 10 times more!

Just received 4 of them from friend who got them through United Hobbies.

I was little sceptic with pricing bellow 4$ and installed them on low wing
30's racer on OS 25 egine. With wing span of 40" I could install 2 of them for wings and still have total weight for all servos at fraction over 1 oz !
Response is very positive and no usual "dead band" around center as found on other "cheaper" servo models.

They definitely get my vote.

Next order I am getting some more.
