rubber "cushion" on flap support tube and flap spring questions

[DBeaulieu]

Is the rubber bumper just to prevent metal to metal contact between the tube and the flap push rod when flaps are retracted...or is it somehow used as a travel limit and has to be an appropriate thickness?

Also, does anyone cover the springs with a protective sleeve of sorts?

Thanks so much!

The rubber (or any kind of cushion) is to prevent metal to metal contact. I have used silicon engine baffle material. But other materials work fine also. Mark

Thanks Mark, I used 1/8" rubber strip glued in place with 1300CL
