## Description

This is a left-handed RC boat propeller with two metal blades, measuring 40mm in diameter and 4mm in shaft size. It weighs 6.2g.

Review: Too fast - I put this on my 24" barbwire XL2 after grinding off part of the tube the blades are mounted on to make it fit. It is bigger than the OEM plastic prop and it made my boat run way faster than it ever has, incredible speed! Afterword when I opened it up the motor smelled like an electrical fire. I don't think I can run this prop very long without burning out the motor.
Review: Works perfect - Works great on UDI Arrow 5 . 27 mph with a 3000 mah battery going about 6 minutes
