The Gemfan 1614 is Gemfan's 40mm ultralight release for the 2025/2026 indoor season! It's a polycarbonate prop designed to balance stiffness, durability and weight. 

This is a strange 1.2mm shaft prop for uncommon brushed motors. 

Shaft size: 1.2mm.

This could be enlarged with the 1.4mm drillbit we sell to fit on 1.5mm motor shafts.
