The KO Propo 35517 Metal Gear Set offers a combination of metal and plastic gears designed to replace ageing parts in a PDS-947FET. It is a practical kit for restoring dependable servo movement and extending component lifespan.
Metal gears withstand higher stresses and wear more slowly than plastic alternatives. They help avoid stripped teeth during heavy use, so the 35517 is well suited to anyone who pushes servos in competitive or demanding models.
Swap-in is typically manageable with standard hobby tools. Work cleanly, follow the PDS-947FET disassembly instructions, and check gear alignment and smoothness at reassembly for reliable operation.
