Promise Hobby Alloy Magnetic Propeller Balancer – For RC Boats (Gas, Nitro, Electric)

If you're serious about RC boats, you know an unbalanced prop is a disaster—it vibrates, kills your bearings, and robs you of speed.

This Promise Hobby magnetic balancer lets you get your props perfectly balanced.

It's made of alloy, so it's solid and precise.

Works with pretty much any prop for any boat type—catamarans, sailboats, speed boats, you name it.

And it doesn't care about fuel type: gas, nitro, electric, even kerosene jets.

It's a simple, essential tool.

Just pop your prop on the magnetic bearings and see which side dips.

Sand that heavy side down, repeat, and you're golden.

Keeps your boat running smooth and fast.
