How do you guys mount your 9920 ?

[Dafni]

I use velcro, servo tape or zip ties ..... or all at once:) A little padding won't hurt, because the electronic components on the bottom are just protected by the shrink. Some foam are whatever

Here's an old pic of my Revo, when I still had the 9L. Between the mount and ESC you would find a strip of thick velcro. I also use 2 zip ties on this one.
