HK-282A Single-Screw, Ultra-Micro Servo 2g / 0.2kg / 0.08sec

 Mal Bond 12 points

The rotary servo has Torque: 0.2kg at 1cm 90deg from the center. The Linear servo has Torque: 0.08kg in a straight line. So the rotary servo is 2.5 times more powerful at 90deg to the thrust line.

No they are analogue.

 Mal Bond 12 points

They are so cheap it is not worth trying to source and fit gears. Just economics and logic I am afraid :-)

 __bare 714 points

Agreed BUT the Brochure Babble above says: "the gears are replacable"... But they don't sell them :-)

 Mal Bond 12 points

If you could order gears it would take time to get and probably adding up costs would be costing near the price of the base servo. I see they will sell them at $3.81 each. I ordered 6 when I needed 4 to cover off such losses with no extra shipping cost. If you do break one you would have some spare parts from a broken one too. Besides, I would not want to be opening one up and refitting parts at this size :-) Sadly this is a throw away world and $3.81 is not even worth bothering about :-)

 e_lm_70 431 points

Just order it ... this will give you precedence once it will be back in stock ... else ... there are many similar micro servo that you can buy faster in HK

No apparant differences...

 Palle_Plutt 5 points

Hi Difference is that one is screwed and the other is glued. So if it's screwed you can change gears.

 magnusEl 1215 points

The case is hold together with one screw on this version. on the other one the case is simply pressed together, not glued.

 louigi600 218 points

I was shipped the pressed version for the screwed one. But I can confirm that the unscrewed are pressed and not glued as I opened them up anch saldered different servi leeds. As for the gears: well maybe it's possible to change then but where would one get the replacement ? and would it be feesable to replace them (time and cost) ? I would tend to think that it's not feesable to replace anyway, at least not on this servo.

The only difference is that the 282a has one case screw and 282 has 2. Products were molded in orange plastic rather than black as pictured

 Sergey 54 points

No, I got in black.

 MegaTesla 576 points

Good for you. Let me rephrase: They CAN also come in orange.

 e_lm_70 431 points

Mine way black to, just received few days ago ...

 MegaTesla 576 points

I just got another batch, orange again...

 Sergey 54 points

I bought a 282a and 282. The difference is not noticed!

 e_lm_70 431 points

there is 0.2g difference due to more screws in one type then the other

 trueblue2k2 10 points

The screwed cover one (282a) requires a standard 4.5 to 6.0 volts. The other one (282) requires 3.5 to 4.5 volts as available with a single LiPo cell. Don't exceed maximum voltage rating to avoid erratic operation or even worse, permanent damage to the servo chip.

 davereap 4 points

no the quoted voltage specs are the same... only their torque is quoted different, the 282 is quoted at .22 the 282a is quoted at .2

 Sergey 54 points

Buy this "PRODUCT ID: MOL125M-LEAD". And fasten the other end of this "SKU: AM-1021Ax10"

 Papy Solex 10 points

Hi,
Why not, you have just to pay attention to the color of the connecting wires..*o) Good flight..*o)

 Richard 2 points

I bought a crimping tool at my local electronics store (Torrance Electronics) for $10 to crimp the pins they sold me to insert into the plastic housings they also had that match the HK 8 channel receiver.

 Sergey 54 points

Yes, this servo works fine on 5 volts
power receiver.

 Jeff 28 points

But the 3s batts push out 7.4 volts... Won't that be too much?

 Jeff 28 points

I meant 2s batteries put out 7.4 volts... Shouldn't my Rx limit the out put of the power to the servos though??? I am so confused. I have both the nano orange Rx from here, and the nanolite Rx from $pektrum They use the little JST plugs. I need to be able to use servos with them, and a 2s battery. What servos will work??

 Fluggs 79 points

Your ESC will limit the voltage to -5 volts which will filter through to your Receiver and servos

 davereap 4 points

If you worry about the return voltage from your esc...put a 1n400x diode in the line with the grey stripe poiting to your RX, this knocks the voltage to about 4v instead of the usuall 5v

 magnusEl 1215 points

The case is hold together with one screw on this version. on the other one the case is simply pressed together.

 ohnjay 57 points

Thank you, very helpful

 respawned 12 points

Yes but you will need to solder a JR plug onto it, also this servo is actually for 1 cell lipo but should handle up to 5.4 volts although you may risk damaging it. I have bought 4 already but using them on 1 cell with 4 channel FM receiver that works on 1 cell. They are very good little servos, 5 stars.

 NitroCharged 303 points

The original batch used to twitch when using them on 5V. The last lot seem to sit quite still on 5V now. I used a 1117 3.3V regulator to lower the voltage supply to the servo from 5V to 3.3V (on a a 6100 rxer) and they work extremely smooth like this.

 sklenar 127 points

My do work well on 5V - but that were only tests on tester, no real flying yet.

 magnusEl 1215 points

I have run them in a 30mm EDF Draken on the controlers Bec a few houre. Still working.

 magnusEl 1215 points

The distance from hole to hole is 23,5mm on the largest one.

I would use it in planes up to 100gr flightwight and yes these servos are strong.

 xsteal 59 points

i use it in the Event 3d from Jens Kröner. www.link 185gramm. Perfekt Servo. Works also on little windy days!

 Matias Enrique 4 points

yo lo uso en un modelo de 3d de 26 inch foamy para los alerones.. hasta ahora funciona perfecto .. y a soportado mucho golpes jaja

 H-KING_SCOTT 5161 points

Not directly, no, it will burn out, the BEC on your speed controller will supply the correct 4.8v via the reciever.

 sidd232 647 points

Hi Jason5001 thanks, i am planning to use it with the mini yak that comes with 7 amps esc, they recommend 2 cells, so do you think the esc will provide the right voltage?

 H-KING_SCOTT 5161 points

Yes, the ESC will supply the right voltage to the RX and servo, the voltage of the Lipo [7.2v] is reduced by the internal BEC in the speed controller, so it will work fine.

 Thomas 10 points

No, I tried it with a 2S lipo and the servo got really (!) hot. You will need a BEC, if you have a 2S lipo.

 hudsonvx 60 points

No. this servo ist only for use with 1s Lipo. Greetings Olli

 one-flight 55 points

Yes I use them with a Turnigy 6 A esc - still no problems, they seem to be quicker and stronger then the 2,5 Gr blue arrow

 shaneroo 43 points

you can use any servo with 2-cell Lipo as long as ESC has BEC. Only Servos listed as High Voltage should be used with anything over 6v.
Be sure your reciever can handle anything over 6v if you don't use BEC.

 Matias Enrique 4 points

este servo es para usar con 1s lipo..

 magnusEl 1215 points

Just remember: red is always black/brown is always - yellow or orange is always signal If not, something's going wrong.

 ottod 24 points

If it is orange, red, brown in that order* orange is signal, red , and brown neg.

 Andreas 34 points

Hi, don't care about 0,2 volt more. Under load the v-booster will sink down to 5 volts.

 petran@in.gr 8 points

It is working with no problems with mine!

 ad01974 5 points

it will work on 5.2v, but the lifespan may be reduced. it may last only a few seconds, but more than likely will last for .5 to 1 hour

 Wilhelm 255 points

You don't even need the v-booster. I use it in a very small Fokker D7 with a 1s lipo without problems. Wilhelm

 Roy_T 134 points

No problems, your receiver will limit the output voltage to the servo. I'm using the Turnigy 5A 1S ESC (w in-built voltage booster) with this servo for a micro flyer.

 davidTs 142 points

Which Walkera receiver?

 ankurkaul17 111 points

No they don't at the moment. I think they should start stocking micro rx as well.

 gsnflyt 123 points

A $pektrum DSM-2 compatible 4-6ch receiver with plugs to match would sell well for these servos and the Ultra Micro 1.7g linear servos. It's a ***mer that HK is selling these tiny servos with plugs that almost all cannot use...I am still trying to hunt down reasonably priced micro JST plugs for the HK-282 and U.M. 1.7g linear servos.
I've had these servos for months and would be nice if I could actually use them someday soon :(

 gsnflyt 123 points

Is B U M MER a bad word that HK has to censor? :/

 DiaLFonZo 74 points

Is this work www.link

 DiaLFonZo 74 points

sorry link aint work. X8 R4 4Ch 2.4GHz Receiver (Mini JST plug)

 gsnflyt 123 points

DiaLFonZo,
No, the X8 R4 4Ch 2.4GHz Receiver (Mini JST plug)(PRODUCT ID: X8R4P) will NOT work. I have this receiver and the HK-282 and U.M. 1.7g linear servo plugs are too small. Electronically these tiny servos will work as long as you change the plugs to the larger size micro JST plugs.

 Straight Up 743 points

Use a voltage booster on the supply to the Receiver: /uh_viewItem.asp?idProduct=11784 Power the servo(s) directly from the 1S Lipo, run only the signal cable(s) from the Rx to the servo(s). The voltage booster ensures the Rx runs at enough voltage despite 1S battery. Don't reply "this won't work" - I've tried it and it DOES work. Since the servos and battery run on a common negative wire there is no need for anything other than the signal wires from the Rx.

 Camboui 134 points

Replying to OP (originale poster), yes the OrangeRx DSM2 are supposed to work with 1s.

 magnusEl 1215 points

But does this servos plug fit the reciver?
I dont find any Orange Rx that use this plug...

 BiplanNorway 19 points

Good question, I've searched the web site and I did not find any micro receiver. Guess this servo a replacement for micro helis that comes complete with receiver and everything. It's possible to replace the connector with a regular one if you can solder. Pulse width is identical to Futaba and other brands.

 salat 73 points

anybody know who sell compatible sockets for these servos plug?

 Jackrr 224 points

it looks exactly the same, you're right. As the title says "single-screw" they propably found a screw that isn't necessary and now sell it as a new product…

 Ramir 715 points

The weight is identical for both servo types : 2,4g with cable and plug but without lever and small fixing screw. So, as usual - no correct info from HK.
And be careful - this servo is possible to use with ASSAN X8 R4 4Ch 2.4GHz receiver (Mini JST plug) only after plug change!

 magnusEl 1215 points

The case is hold together with one screw on this version. on the other one the case is simply pressed together.

 maro89 5 points

Yes is different! the weight is much important in r/c plane especially in micro airplanes.

 Ramir 715 points

May be without cable and plug. Together and without lever and fixing screw 2,4 - identical with weight of HK-282

 davidTs 142 points

See my review (~2.45 gr without a servohorn)

 BiplanNorway 19 points

Weight is about 2.5 grams with servo arm and 3 screws.
