Almost a 5'' Prop but HQ knows what they are doing when it comes to miniquad props. The have developed a new type of 4-blade propeller that was designed for tight cornering and insane grip. The slightly reduced size at 4.8" and reduced pitch pair perfectly with the addition of the fourth blade.
Most 4-blade propellers struggle with durability, but HQProp has made this propeller tough and durable in order to withstand racing conditions.
