Precision cast from Copper-Beryllium-Titanium!

The best upgrade for every boat!

Give your boat a new burst of speed...it's as simple as bolting on a high-quality GrimRacer metal prop! Racer-designed, USA-made GrimRacer Copper-Beryllium-Titanium props are now available almost everywhere R/C marine products are sold — making it easier than ever to get the metal prop advantage.

The most accurately cast metal propellers available.
Ultra-clean casting and true center-bore hubs mean that each prop is near its balance point — right out of the package.
Material won't crack or shear like plastic — remains sharper longer, with less dulling and chipping, and is safer too!
Can be fine-tuned with less effort than stainless steel, while holding shape better for balancing, sharpening, and changing pitch.


Flex-resistant but not brittle, these lightweight metal props feature raised lettering on the hub for easy size identification.		GrimRacer High-Performance Metal Prop technology gives an even greater competitive edge to high-performance boats such as the AquaCraft SuperVee 27 and Miss Vegas hydro.		Each prop comes in a reusable plastic parts box to protect it from performance-robbing pit box damage.
