Compatible with: Rockslide RS10 

This part was acquired in a large lot of RC parts and I do not own the model that this part could go to. So other folks who need or want these parts for their RC models can get a great deal on them. 

Many of these parts have simply been stored for a while so the packaging may not look new but the parts have never been used.
