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 4 Series (types) of propellers for many different applications from 15hp to 120hp.

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 Series 2 and Series 3 blades now feature our DuraTuff leading edge.

Incredibly smooooth, Incredibly Quiet, Incredibly Powerful, Incredibly Efficient, Incredibly tough.

The results of this process is the Bolly Optima Series range of propellers.


You deserve the best in propellers, and here they are ....



Bolly Optima Series Information: All Series 2, 3 & 4 blades are sold as digital weight matched component sets, although the user is responsibile 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 full Quality Assurance 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.

PLEASE NOTE : Whilst it is our job to supply our customers the best performing propellers for as many applications as possible, it is the aircraft owners responsibility to determine the suitability and legality of the propeller they choose to use. It is an accepted industry standard that propellers are not returnable / refundable, especially once they have been fitted.

 

In development : Bolly In Flight Adjustable Propellers. We have been testing since late 2005 and showed our first pre-production version at Narromine 2006. For more details, se the IFA page.
