There are a number of ways you can go. You could go with a pushrod setup, like this:

Where you have a short pushrod and a short plywood control horn on the spoiler and short servo arm. This is what I used on my BD.

Or, some guys have used magnets on the spoiler and then just have a long servo arm and that pushes directly against the spoiler to lift it. This is what I have on the Allegro.

hi,
i just did a couple for customers here lately.

the first pic is on a Victory.

here is how i just did a Saphrano RES on the other three pics.

the servo screws to a ply plate, that has some rails glued to it,
so i screw the servo to those rails.

then i run screws up from the bottom into the ply plate.

so the whole unit can be removed if you ever have to replace a servo.
