A couple times now I have heard that I need to be concerned with the Sling TSI s tail slamming against the ground. What can cause this is two people getting up on the steps at the same time. My Cirrus had a rubber bumper on the rear tie down. I looked at getting that exact bumper but it feels to hard to actually cushion the blow. I tried many different materials until I found the right hardness. This material is just right. It will act like a sponge and dampen some of the impact force from the above scenario. I plan to attach it with some low quality glue. It already fits on pretty tight and I want to be able to remove it if necessary.
If a tail strike happened during take off, this material would most likely not be hard enough to provide sufficient protection but it would help. Any material that would be hard enough to protect during take off would not likely protect from a stationery tip back. It if wears out over time, It is easy and cheap to replace, so no biggie if it comes to that.
