Radio Active 45mm 2-Blade Waterscrew M4 LH – H-RMA3042

The Radio Active 2 Bladed 45mm Waterscrew SR Red Nylon M4 LH (H-RMA3042) is a practical model boat propeller for general RC marine use. Its tough red nylon construction helps keep weight down while providing reliable durability, and the two-blade design offers predictable running for a wide range of setups. The M4 left-hand (LH) thread is suitable where a left-hand rotating propeller is required; always verify shaft thread and rotation before installation.

The bright red finish makes the prop easy to identify in your spares box and on the bench. Ensure adequate hull and rudder clearance for a 45 mm diameter propeller and secure the prop with the correct hardware.
