These shock absorbing skid collars are made from high density, high quality NBR foam, they are perfect for absorbing the energy from that not so perfect landing with your multi-rotor.
Outside Diameter: 32mm
Inner Diameter: 10mm

Excellent quality, lightweight, smoother landings when you go down harder than expected.
Just watch out for when the ground is wet; it will soak up water and mud.Very big and very good. I use it for my retracts on copter, and it is working well
These guys were much larger than I had imagined, but thats not bad as it means more shock absorption. Anyways, the collars easily fit on 8-10mm tubes. I use them on 8mm landing gear tubes so they are a bit loose. I just zip tied around it to make it tighter so it wont fall it. Useful for larger quadcopters, especially landing on hard surfaces.
