Servo's SG 90 generics

(1/2) > >>

Brian60:
Is this really the smallest servo available? I need something half this size ideally, anyone got a clue please?

Allnightin:
If I understand correctly, the SG90 weighs 9 grams

You would do much better if you look at component shop offerings:

Brian60:
I've actually managed to locate one on the Hobbyking website, a nano size weighing just 2 grams, physical size along with weight were my considerations, but as they were only £2 each I ordered a couple of varying dimensions, I've a feeling the smallest will not have enough torque to move even the rudder which is only a 10mm by 10mm blade, but we will see.

Subculture:
More than enough torque for a small rudder that size.

Hi all, there is a point to watch with these small sevos.  The first time I fitted one I involuntarily moved the rudder and it stripped the plastic gear in the servo.  So be careful.
