Radio Active 45mm 2-Blade LH Water Screw H-RMA3009

The Radio Active Ripmax 45.0mm 2-Blade LH 4BA GFN X W/Screw, part number H-RMA3009, is a glass-filled nylon water screw for model boats. It has a 45.0mm diameter, two blades and left-hand rotation. The moulded glass-filled nylon construction provides strength and stiffness for high-speed electric drives, performance internal-combustion drives and fast planing hulls.

A tapped brass insert is moulded into the water screw for the 4BA connection stated in its name, and the required screw is included. This propeller is intended for applications where a left-hand, two-blade water screw is required. Its dimensions, rotation and material make it suitable for comparing replacement or build options for fast model boat setups.
