these are great little servos, I am using them together with the orange micro rx in a 3 oz aerobat...their plug is correct...I used a diode in the return line from the esc to keep the voltage to their spec..
nice and smooth no complaints with these, I have ordered another 6....
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 :-)
I bought at least 40 of these servants and no one gave me any problems. return = perfect, light and powerful for its size and weight they have
I use them for micro-models

My hope is that HC provides them with thorns from 1 mm to use them on HC recipients who are also exceptional
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.
What exactly is the difference between the 282a and 282. I know one uses a screw to hold thecae together, and the other is compression fit.are there any other differences? Why is the one without the screw .2 grams heavier? Thanks
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.
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.
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??
I've bought some.
This one has a micro plug and dosen't plug directly into HK-T6A-V2.
Is there an adapter that I can buy?
is it best to cut of and solder another plug (in this case which plug should I buy?).
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.
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.
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.
i have a question about the voltage.
they say "operating voltage cannot be higher than 5v".
Do they mean exactly 5,0v could it even be a little more like 5,2v?
-> there is a v-booster on hk website that delivers ~5,2v. so will it work?
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 :(
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.
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.
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.
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!
I got three servos and used them on Multiplex Fox.
Positive: the price, a neutral point is kept They look solid (much better than 2.5 gr servos)
Negative: They are 2.45 gr (not 2.0 gr!) If you connect to Walkera rx they wouldn't work: you have to exchange "-" and pulse contacts Maximum operation angle is too small (at least with my WK2401 TX)

I have no problem with the build, or the quality so I can't rank it low.
But the connector is not compatible with my JST equipped reciever.
It is however the same size connector as on the Walkera Heli's so it can be used as a replacement on the those.

I am very satisfied with this small servo. Cheap and seems to work very good.
The plug will fit into Walkera rx. But the servo will not work. Got advice from HK users to change the outer plugs. Thanks. This is easy, no soldering, no crimping. Need a fine forceps or similar to unlock the snap fit which holds the cable with contact in the plastic part of the plug. No problem.
Warning! Bought 4. All servos had switched plus and minus pole!!! Watch the colours of the sevo cable! All the other servos and receivers with jst plugs have the colour arrangement yellow-black-red. These are yellow-red-black. (its quite easy to switch back if you open the servo but only if you recognize it before the servos an the esc go up in smoke)
