Bumpers! We don't need no stinkin' bumpers!
EPP is also a good material. I think EPP stands for Expanded Polypropolene.
I use EPP to pack my radio gear in my R/C airplanes. It doen't transfer vibrations to the radio like foam rubber does.
It can also take a lot of abuse. Guys in our club build planes out of the stuff. You can take a glider and slam it into the ground and the plane will just bounce with no damage.
