RUKO Easy-Lock MK3 Quick-Release Propeller Adapter for 6mm Shaft

Changing propellers on electric RC aircraft can be a fiddly, time-consuming task, especially when you need to swap props quickly at the field. The RUKO Easy-Lock MK3 solves this with a tool-free quick-release mechanism that lets you change propellers in seconds without loosening collet nuts or reaching for tools.

Who is it for

This adapter is ideal for hobbyists and pilots of electric flight models and RC aircraft who use brushless outrunner motors with a 6mm shaft and propellers with a 6mm bore. It suits anyone who values convenience and wants to minimise downtime between flights.

Main features

• Quick-release lever on the propeller side allows tool-free propeller changes.
• Collet clamp on the motor side provides a secure, vibration-damping fit on 6mm motor shafts.
• Constructed from aluminium and high-strength plastic for durability and corrosion resistance.
• Compatible with propellers having a 6mm bore.
• Designed for brushless outrunner motors.

Tips

Ensure your motor shaft and propeller bore are exactly 6mm for a proper fit. The collet clamp should be tightened firmly onto the motor shaft before first use, but after that, propeller swaps are purely tool-free via the quick-lock lever.
