The Prop Guards for 3DR Solo from PolarPro help prevent the propeller blades from coming into contact with objects during flight. This adds a layer of protection in the event of a collision as well as an added safety element. The guards quickly slide onto each Solo arm and have a retaining clip, which locks in place. They can be easily removed for storage by simply unclipping the retainer and sliding the guard off.
