What great ideas for spoiler setups. Thanks for sharing, this will come in very handy for my refurb job.

All great ideas... but I've a doubt!
In case of a (n electrical) servo's failure, not so frequent indeed, you woun't be able to access the vane to replace the servo, because the spoiler is mechanically locked;
you should force to opening the vane, probably damaging the spoiler.
Has anyone thought to use a piece of rubber or a spring to keep spoiler closed, and use the servo's arm just to push upward the spoiler?
Is it a good idea? Could it work?
Thanks, Piero.

My spoiler linkage has evolved to no linkage at all.

In most of my sailplane wings I mount a HS-55 servo (with long stock arm). This servo arm pushes directly against the bottom surface of the spoiler.

The spoiler returns to closed position by a small rubber band attached from lower surface of spoiler to lower surface of wing. With this arrangement there is no possible binding of the servo when in the "down" position.

The Truth is Not Forgotten
and add a little lead to the spoiler to keep it closed

They work well, keep them at 6.0v or less for longer life.
