The sample I tested is smooth and quiet in operation. The size is similar to New Power XL-16HM/17HMB but slightly taller, so bespoke wing servo mounts will require minor modification.but heavier then describtion: 20.8g without lever/screw. Smoothly and low noiseBought 4, all OK. BUT: Weight is 20.8g without lever/screw! 3.3g heavier than described. 4*3.3g=13.2g. Good centering, low noise.Bought 4, all OK.

The 6th works also, but the manufacturer forgot a minor detail: the output shaft bearing...
So the servo is not usable, but for that price, I will not complain.credo e spero che sono ottimi e la prima volta che li comproBe carefull.The servo is very bad and dangerous cause when is back in land looks ok. When the servo is working a lot the first plastic gear (on the motor shaft) starts to fail cause the servo motor becomes hot and the first gear starts to drift on the motor shaft (when the servo colds down the servo looks ok). But in the air you loose the plane.Good price !! excellent quality !! will buy more.
