Just flew this servo on my 550E 3G. Couldn't ask for more from a tail servo, just amazing. Prior to this, with the DS620, I had wag in large heli mode on the gyro, had to set small heli mode to get rid of it. Now on large heli it's just solid with not even the slightest movement. Used the same arm and grommets, as the DS620, but had to raise the servo slightly, using a 1.5mm packer. Absolutely brilliant for the price!!!!!!!!!

Mine worked fine (on a HK500) for about 10 flights.

Then it gave up in flight - just did not respond at all.

The motor inside seems still powered, but does not turn servo arm - feels like something cracked inside. Maybe some missing teeth on the gears..

Will not buy any of these HK Mi servos again.

Just as fast as the S9254 tested with my JetiBox.
Partly aluminium body.
Almost no slop in the gear train.
Long term testing is yet to be done.

Recived my servo a few days ago, but because of work I havent been able to test it until now and it was dead.

The build quality isnt the best either, the shafts holding the gears are supported by the plastic top without any bushings and will probably wear rather fast and cause play with the high torque.

Another thing I wasnt to fond of is that the servos dosent have an end to their rotation, and mine started to spin uncontrollably after a few seconds connected. So if you dont test it, or it some how fails when your out flying, at best it will rip off your controller arm, or you will have to land with one your controller surfaces at full.

So my recomandation is: Stay clear, or order more then one incase one dosent work.

Got this servo and first impression is great. Use it for elevator at the moment and there its ultra fast, precise middlepoint without any overshooting. Perfect for all possible manouvers. Definitely first choice compared to other products specially for this price. Also much more expensive servos cant beat this servo.
