????? ??? ????? ????????. ??????????? ?????? ?? ??????????.
Seems fine with Orange RX415 micro receiver but watch out for wiring of the servo lead plug. Mine were supplied wrongly wired if it is to be used with the RX415. I had to swap the connections around at the plug. I have posted a more detailed description under the Discussions tab.
These are pretty good quality and lightweight
but the downside to this type of servo is that
it slides forward and back rather than rotating
on an axis like standard servos, so you dont
have as much travel for control surfaces. Like
You would with a standard servo.

One thing I don't get is why there is 3 "Adjusting" holes
on the horn they don't speed up or slow down the speed
they just raise and lower the control rod which is also pointless.

This servo worked fine with a 2s but sometimes if you move
you're stick from lock to lock really fast the servo tends to
not be able to align correctly and stutters back and forth really quickly.
no plan for use very nearfuture.nice product. just weighted- shows 3.0g not as product description but looks nice product.
Installed this one in my Nine Eagle Extra 300 for rudder when repowered with brushless engine, works really greate :)

" In one direction goes fast like first one, on other direction it goes little slower and servo shakes very badly ."

Ive had the same problem with two servos.
I solved it with a little bit of Sonax SX90 multifunction spray (a kind of contact spray), sprayed into the potentiometer.
Now the servo is moving precise and very fast in any direction and position.
Good value for $$ work great!!! Can mod for MCPX use.
i was prepared in advance and changed the wiring to be correct but now both burnt out! and damaged 2 20A ESC's while trying to sort it, also a hole in my pants from the servo chip melting. i still dont know if the wires were in the wrong sockets or just used wrong colours. can someone please sort this out, i cant keep buying more and burning everything.
HK please send me 2 more that have been tested and proved to be working and have correct wiring and correct colours. (i waited 3 weeks for expensive courier and now have a plane that i cant fly until i get some that work).
