Actuonix PQ12-R リニアアクチュエータ 20mm、100：1、6V、RCコントロール

The PWM versions are a bit sus. Actuonix simply soldered a pwm cable to their 3 pin ribbon cable coming out of the servo (minus 1 star)... Like why is there this fragile ribbon cable on my $70 servo?? Worse yet, the solder connection is lined up so it bumps against the side of the servo. So if you "slide" the servo into a 3d printed slot... you better have made a huge tunnel for that solder joint! The price makes zero sense. They do work well, and don't jitter. But goodness they are absurdly expensive for what they are. (minus 1 star) Where is the competition?

First time using this type of linear configuration. It is installed in a 1/48 scale submarine model to activate the forward dive planes and works GREAT ! See Video at 6:05 to see it in action. https://www.youtube.com/watch?v=8R86uuW7j4Q&t=89s

Easy to setup and pretty powerful. Used it to actuate 3 fingers of a flexible robotic gripper.

This linear servo is easy to use if one needs a linear motion. Just simply plug need normal servo signal, full stroke takes about 2 second. The precision with servo pulse width seems to be good. I have not put it into real action yet. Need to design mounting properly first. The only one thing I do not like about this product is that it is very difficult to get mounted since it has only one 3mm hole at the end. If Actuonix folks sees this review, could you please make more mounting in the next model.

I do not have a lot of experience with this yet, but in a quick test, it seemed to meet the thrust and slew rate specs (Most RC servos I have tested do not have the claimed stall torque). It seems pretty smooth, although there is a bit of backlash. Overall, I will be using more of these in the future.
