ARRMA 27T 1mmP Safe-D 5mmS Pinion Gear - ARA311057

• Strong and durable steel for long-lasting performance in extreme RC conditions
• Precision manufactured wide tooth profile for smooth operation
• 'D' shaped hole to match motor shaft profile so drive and brakes are not lost if the set-screw backs out
• Suits 5mm motor shaft diameter
• Precision manufactured threaded set-screw hole
• E-clip supplied for motor shaft pinion retention
