109E3 has no slats, that is right?

No springs at all. Its just there on roller slide or, in case of before the late 109F, a swing arm. The slats are simply sucked out into their open position by the airstream pressure due to their aerodynamic form.

You can actually push them in or pull them out with a finger on the ground.

I've always thought it might have been a good idea to reduce the deployment angle of the slats and then run a small cable between them to make them deploy/retract together, but then they wouldn't have been operating as efficiently ...

Interesting stuff. Thanks for enlightening me guys.
