Default Adjustable endpoints on HS-75BB retract servo?

Does the Hitec HS-75BB retract servo have adustable endpoints? I currently have an Airtronics 94734 which does not. It would certainly make setup much easier.

Thanks,
Chris

Default RE: Adjustable endpoints on HS-75BB retract servo?

Most retract servos are designed simply to toggle between two points 180 degrees apart and have no provision for end-point adjustment.

This is because, when connected up properly, they rely on the fact that they exert the greatest pulling/pushing power at the ends of the travel because the effective torque radius is reduced right down util it actually becomes zero at that point. This also means that they kind of "lock" the retract linkages into position (either fully up or down).

If you played with the end-points you'd lose an important part of this mechanical advantage and risk stalling the servo or having it damaged by landing loads.
