Pull-String Servo Pulley, 10/Pack

Overpriced perhaps , but…gets the job done, fits into a small space, improves torque, improves to a more linear control range.
Sorta hard to fit it onto the kstx06 but it does fit with a bit of struggle.
Should come with a diagram or some simple instructions for the price.
Works though. Would probably buy again If I have to…for space constraints.

I'm using these on all my F3K & F5K planes now. The rudder and elevator movement are uniform throughout the servo's travel. These should essentially never wear out with proper intallation and use.

Tried with wire throug servo arms first and had trouble centering the control surface, these were much easier to fine tune. I also like the constant torque output that these provide throughout the servo range. Used on KST06

Received them quickly but since there's snow on the ground haven't had a chance to install them yet spring is around the corner will be testing them shortly happy New Year to all

I bought these pricey lil buggers with hopes of them working with the Bluebird 101DMG servos I have, not the same size shafts.
