Recently getting into quadcopters I was sick of my lock nuts and base getting scratched up from bouncing off the concrete and figured these would be less drag in the grass.
I have an extremely strong double sided (low profile) foam tape that holds these skids to the base no problem. The clearance holes are big enough for me to take off the base with a Traxxas T-wrench.
I may work on a Version 2 that uses screws instead of tape if you guys want, but have found screws just end up splitting the plastic.
