Biela Hawk Eaglewing

Propellors and Tools

Biela semi scale and other high quality CFK propellors.

Both the wooden as well as the Biela propellors are factory balanced, however for optimum performance and longer lasting engines, all props need some balancing especially after drilling.
A few light dabs of clear acrylic or polyurethane paint from a spray can towards the tip of the lighter blade is normally the best way.
