Great servo for micro airplanes. Use one for aileron on NE YaK-54 - 2S BL with ESC 6A, BEC 5V.
Working fast and smooth.
Tested with 1S LiPo - same result. This is my choise for future!
After two weeks, finally I have them.
About "dimensions of the part sticking out under the servo"
In direction:
A = 4mm
B = 6mm
D = 5mm shifted from centre to bottom side if look on image
80 mah battery won't last long with the Rx & 2 servos drawing power.
It'll depend on how stiff/ free your control surfaces are (if the servo needs to work hard it'll draw more power) & how much you are working the sticks.
Assuming everything is perfect, I'd hazard a guess at 15-20 minutes. If stiff tail surfaces & lots of stick movement, perhaps 5 minutes.
I would fly for a timed 2 minutes & then check how much power remaining to determine a safe flying time.
Good luck.
Do these have a full mechanical range of 180°*. The HK-5320 ones only have a mechanical range of about 100°* (caused by the potentiometer, not only the mechanical stop).
On a classic RC system you mostly use only about 90°*, but in this Arduino project 180°* would be welcome: ***********instructables****/id/Zappelin/
In short, I'm looking for the lightest 180°* servo.
Given the weight of some of the new CCTV cameras out there (1-4g) it makes sense to me to take two of these and glue them together then mounting a camera (if it crashes and breaks, who cares, replace them)
Plastic and 0.04sec 60deg *4.2v seems ideal!!
Can I replace the servo lead with a regular servo connector? I'm happy to test if they are OK at 5V and since they arent critical to the safe flight I dont mind if they burn out on occasion!
Any similar experiences or thoughts?
Hi Vlad,
How do they go, I have read some bad experiences about the servos warming up and warping the plastic. Has anything like that happened to you?
Thanks
yah the casing is almost identical to the other servo with less power so the bulge is most probably housing the bigger motor but I would like to know the dimensions of said bulge. I doesn't seem to do the whole thickness of the servo.. Anyway I have another week to wait for the delivery and I'll see then . The dimensions would help with my CAD drawing right now..
Its the motor, same servo in my axe100 cp, but the stock axe cp or rebranded nine eagles 125 servo cost 9 bucks! So this is a sirious bang for your buck!
Is there a way for me to get in contact with the company that makes these servos. I would like to convince them that they should make slower but stronger servos in the 1.9 gram class :)
Most micro servo's draw around 400/500ma peak current,so one servo will be ok,2 will be on the limit,depends on the loads you are putting on the servo's and the type of flying you are doing.
Mine did not work well with that exact ESC, or rather the voltage of 5V. I had to use one or even two diodes inline on the red lead to lower voltage and stop servos from jittering like mad.
Can I use this servo with a 2S system? Are the plugs compatible with Orange Rx R415 $pektrum DSM2 Compatible 4 ch Micro 2.4 ghz receiver?
Sorry...two questions!
No, these servos are only rated for 4.2 volts. I accidentally used this servo with a 5 cell nihm rx pack just to test a 415rx while binding and it got hot enough to warp the plastic case! So remember nothing over 4.2 volts.
Please do NOT use this Servo with 2S! (like me)
This part is designed up to max. 4.2V 1S and not max 8.4V 2S.
You will blow up this Servo with 2S
Remember that a full charged 1S LiPo has 4.2V! and not 3.6V
2 cells are fine, put a diode 1n400x in the red lead with the stripe towards the rx.. this will drop the voltage so all is safe... Ive got 3 of these servos working nicely with a 6A turnegy plush esc, orange micro rx...
Can i ask a question? Today i get these servos and in the manual (in german language) its said, that i can use only batery with max 40C rating. Is there any problem when i will use bateries with C rate above 40? because i already buy 2 pack of bateries with 90C... Thanks a lot.
Micro models and small gliders, which do not require large throws and do not travel at high speeds. Weight is also at a premium, so these servos are just the ticket!
My axe 100 cp also use this servo, the nine eagles 125 also use this servo.

I used this servo on my Blade 130x. So far the results seem very promising http://youtu.be/krH-Hs05KVA
Hopefully HK will come up with similar servo with a little more torque, speckturm compatible plugs and a mount for the 130x. 130x is a VERY popular heli.

Great servo, really miniature and the torque is ok for little planes. I use them for smal depron gliders togther with the FrSky VD5M receiver. RC equipmet incl. battery about 10g! The connectors fit well! Just ordered some more...
