What really counts is what you, the user of our product thinks of our product. Since our first moulded props were tested in October 1995 the overwhelming response from customers has been outstanding - most tell us that the Bolly injection moulded propellers are the best available. We agree.
Test Results - Most of our testing information is (like our design information) confidential. However we can give you an idea of the activities behind the scene in testing propellers of our own manufacture and others.
Below is a reproduction of our testing for the Clubman Series 10.5 x 7. There are several test comparisons with other propeller brands, however we have deleted the brand names in this example.
Clubman 10.5 x 7 test results
The above figures show that at 'normal' power levels the Clubman was a touch more load than most and quieter than all. When used at higher power / RPM levels the Clubman outperformed all the rest for RPM and all but one for noise. These figures at elevated levels are interesting as it shows the prop is flexing much less than others (hence transferring more power). Similar results have been recorded for all other tests we have done in comparison between a Clubman Series propeller and other brands.
The real test of any prop is in the air. Most of our testing is done with either aerobatics or racing style models where performance changes are easier to monitor. However with the exception of customer testimonials , it is nearly impossible to publish a commentary on flight performance without being perceived to have a bias.
The real secret to good performance is to select the correct propeller for your model and engine combination.
Having selected the correct propeller, we can guarantee that the propeller will perform at least as well as, if not better than, any competitor's propeller on the market.
The feedback we constantly receive is how much flyers are are impressed with the low noise, strong vertical 'pulling' power and durability. Try one, you'll like it!
And if you think the above is good, wait till you see our new ProGlass releases for 2009. The performance gains are quite special.
