Vess 27B Stealth Carbon Propeller

It’s as easy as A-B-C! The “baseline” prop that most people will start with in a particular diameter series is denoted as a “B” pitch (“B” is for Baseline). So, if you have a 100c powered 33-35% aerobatic airplane, you will start with a “27B” prop. It will most likely give you the tremendous vertical performance, great acceleration, and low noise that was designed to deliver. If you have an aircraft that is heavier, has more drag, or is larger than a typical 33-35% aerobatic model or has less horsepower, you may need to go down to a “27A”, which has less load. Conversely, if your airplane is lighter, has less drag, or is smaller than a typical 33-35% aerobatic model or has more horsepower, you may use a higher loaded “27C” to properly absorb the power and keep the propeller quiet.
