Great little servo

Arm splines are very tight. Nice package with isolator mounts, servo is precise and strong. This is gonna be my go-to servo for parkflyers.

Great servos accurate, fast and strong. Gears are a little weak under shock loads. Look like gws pics servos but a little taller. Recommended.

I just did a bench test, since the servo seemed to be stronger than the specs say, and the torque (dynamic) was really 1.25kg/cm at 5V!!! Great servo for the buck...

Overall great servo for small electric planes, though are not suitable for 1.5m DLG as the gears dont hold up to hard launches. Small,light,fast and with almost zero slop.

Seems to be a good servo,
I have 2 in my blaster dlg wing and so flown 30hrs on them, fast and precise, torque seems adequate for the job but no stronger then it needs to be, so as long as .82kg/cm is enough for you these should be good.
BTW they have survived a crash and still work.

Bench tested only but seem good as has been said, fast enough and accurate not sure how strong they are but time will tell. Gonna use them in my blaster dlg wing and will report again how it goes.

Over all in consensus with Fireball. New benchmark for cheap DLG solution. Servos are extremely fast with very good response and centering. No noticeable slop. Nice super thin wiring with a total weight of 6.44g with servo arm. Nice set of supplied servo horns and even rubber grommets.

Overall it is good servo: fast, precise, not so strong but sturdy for it size.
Inspection reveals this is GWS pico servo with new electronics.
