This is a replacement propeller for the Moster 185 2.87 is available in sizes ranging from 135-140cm. For the SP140 V2 frame, the maximum allowable propeller size is 140cm. Using a 140cm prop maximizes efficiency and thrust. A smaller 135cm prop offers more clearance, reducing the likelihood of a propeller strike during a crash or faulty takeoff/landing. A good overall size for balanced between the two is a 135cm tri-blade propeller.
E-Props are a manufacturer in France they develop and make high-tech props for Airplanes and paramotors. They are the leading manufacturer of Carbon fiber propellers for paramotors because of their lightweight, high power output, efficient props. E-Props are the lightest propellers made, which in turn give great power output and efficiency. These props are full carbon fiber and include a pair of blades (full prop ready to use)
