WHY BALANCE AND SHARPEN YOUR PROPELLER?

Model boat propellers typically spin at the same RPM as the motor or engine. Any vibration that comes from the propeller can

rob your boat of both power and speed. It can also ruin electronics and even break metal parts. It is always best to balance your

propellers. Likewise a dull propeller can upset the handing of the boat.
