BOAT TYPE AND USE: Different boat types and uses require different propellers, for example, a speedboat may be better suited to a two-blade propeller, while a boat requiring more thrust may need a three-blade propeller. POWER SYSTEM: The power system of the RC boat (e.g. motor and batteries) will also affect the choice of propeller. High-speed, low-torque motors may be better suited for two-blade propellers. MANEUVERABILITY: Two-bladed propellers typically offer better maneuverability, while three-bladed propellers may offer better stability in some situations.
