It's simple, if you want the best performance - use a Bolly Prop.
Strongest, toughest blades available --- NOT fatigue life limited.
We have been designing and manufacturing carbon composite propellers for over 25 years, from 5" to 80" diameter, 1 to 5 blades.
Bolly Props are famous for delivering extra performance and efficiency. And they are smooth and quiet.
"You just don't know what your aircraft can do, until you've hauled it around behind a Bolly", although some props are also pushing !
Recreational pilots have discovered the benefits from the top shelf of propeller design, with our Optima Series Propeller range becoming increasingly popular. Tested to mach 1.001 tip speed.
The Bolly “IN FLIGHT ADJUSTABLE Propeller ” (I.F.A.) is entering the final stages of testing. We are most satisfied with the overall performance of our IFA and after several years of testing and a sizable financial investment we are very pleased with the results as we near completion. Although we don't have a firm date for when we will be offering this product into the market place, expectations are pointing at mid 2009. Bolly Aviation would like to thank all of the pilots and ground personal who have been involved with the development over this lengthy period.
New for 2009 will see more Aerofoil being added to our existing range of props which have been specifically designed to meet the performance capabilities of the faster range of LSA aircraft on the market today. Adding to this ambitious program we are looking forward to trialing our all new Composite Prop designed specifically for higher RPM Direct Drive engines such as the Jabiru and VW, as an alternative to the traditional fixed wooden props. So stay tuned.
