Can I use it with my Futaba R6014HS receiver? Is there any gap at the end of arm tip? I want to use it on a fast performance sailplane (200mph) and do not want to have flutter..

In my experience these are rubbish servos. I have bought 5 of these and 3 have failed on a Turnigy ccpm servo consistency master tester and ripmax type tester running on no load for just over an hour on 6V NIMH pack. First one blue one of the chips on the servo amp board. The other 2 just stopped with no visible signs of damage on the boards. I suspect motors are at fault as if you move the arm it sometimes picks up and then stops again - and there are no pots in these servos. I have not stripped them down and investigated any further. I was going to put these in my HK/Trex500 hybrid Heli.
I always do a reliability test on my servos before they ever go into my helis. These have shown a 60pcnt failure rate. I believe if I left the other 2 on test they would have gone the same way. As a result they will NOT be put into service in any of my models!
P.s. I bought 3, one failed so bought another 2 to replace this plus a spare one - both of these failed - I thought the first one might have been a faulty chip and a bit of a fluke the rest speaks for its self or I am extremely unlucky!

Disapointing !

All 3 Servos have noticeable, or even big sloop in the gears, increased by the Ballbearing having a lot of sloop inside the case too.
On one Servo I can easily move the shaft 0,5mm sidewards, the Ballbearing is moving inside the case.
Problem is that the housing seems to be made with high tolerances.

The Hk MG930 Servos I have are BY FAR preciser and stronger !

Whats the Use of precission magnetic sensors if the Gear spoils the Result.
2 Stars as they are working, but not as expected.

Bin von den Servos überhaupt nicht begeistert, da alle 4 Axiales Spiel haben und das nicht gerade wenig! Die Abtriebsachse kann ich bis zu 0,5mm bewegen. Bin sehr Enttäuscht von den Servos

Don't use this servo on the tail of a 500-sized helicopter, it does NOT have enough torque to move the tail pitch slider when the head is at full RPM. The HK28013DMG should be ok for cyclic, but it's not nearly strong enough to be used as a tail servo.

Output shaft on both my servos has a lot of slop due to the bearing being loose in the housing. Pulled them apart and applied CA around the housing and now its fine. But looks like I'm not the only one with this problem, sort it out HK! Otherwise its a fast powerful servo, no other issues.
