I so far run two of these in two 450 size helis as tail servo, no problems so far and am happy with their performance.

I bought this servo for my Copter X 450, and I can say that I am satisfied, the servo works well, and runs cool, but the finish on it is awful, plastic parts have whiskers sticking out, metal case is skewed a few degrees in relation to other servo parts. The overall feel of the servo is far worse than much cheaper servos I bought. Performance wise it is satisfying, and works with no problems so far.

Fitted in my Gt12 for club racing. I have used it for 4 weeks now without any issues at all. Extremely fast and strong servo at an exceptional price!
Shall definitely be purchasing again.

Worked great while it lasted. Very similar to the Align DS520 in size and performance and picks up exactly on the standard align mounting holes. I was very careful to set mine up to prevent any binding of the tail mechanism. It lasted about 50 flights then failed with no warning, tail just stopped responding. i was just hovering around doing nothing taxing. Luckily I landed with no damage. Tested the servo with servo tester and it was dead, no response at all.
Thought i must have been unlucky, got another one, checked again for no binding and changed ESC. This one also lasted about 50 flights before failing in an identical way. Stripped them both down and the problem appears to be the brushes burning up.

Two of these servos has stopped working for me.
In both cases the servos suddenly went to one end stop witout any apparent reason and after that the servo do not work. The servos had been used in 450 helis with a total running time of less than 3 hours each.
In one heli an Assan GA250 gyro was used and in the other a HK401 gyro
