Bolly Optima Series Propellers are perhaps the best range sports aviation propellers available. We started with a clean sheet and designed the best prop we could. Using the latest in design and construction techniques.

The Design: is from 25 years of design experience combined with computer analysis and computer aided drawing. Available in 5 Series (types) of propellers for many different applications from 15hp to 180hp.

The Construction: CNC Milled tooling for optimum accuracy. Genuine Carbon Fibre-Epoxy construction. Unbelievably light and strong .All metal components are CNC machined from aviation grade alloys to exacting tolerances.

All Optima series blades now feature our DuraTuff leading edge. And the series 5 with its full-length Dura-Tuff protection. Incredibly smooth, Incredibly Quiet, Incredibly Powerful, Incredibly Efficient, Incredibly tough. The result of this process is the Bolly Optima Series range of propellers.

Bolly Optima Series

Bolly Optima Series Information: All Series 2,3 & 4 blades are sold as digital weight matched component sets, although the user is responsible for the Final balance of the assembled unit. Our Digital Weight number takes into account the blade weight and C of G. All BOS components are manufactured with appropriate documentation. Please note we always quote our prop pitch as per actual geometrical pitch at it’s most common size. The common practice of quoting blade angles is useless information, unless giving the radius and a scientific calculator at the same time.
