PROPS FOR .45 SIZE MODELS
The world's most common size of model is the .45, being used in trainers and general sports models.
Whilst a specific prop is not produced for trainers, the use of a Bolly prop will help that marginal model perform much better.
The original Bolly .45 prop was the 10 x 6. This prop will out perform any wood or nylon equivalent.
Further developments have led to the production of a 10.5 x 6.5 and 10.5 x 8. Both of these narrow blade props will offer an improvement. The 10.5 x 6.5 is better in vertical or load carrying and the 10.5 x 8 will offer top performance at lower RPM with decreased noise levels.
The 10 x 6 and 9.25 x 7 are best when wanting straight line speed - also available is the 10 x 6SP, especially designed for Australian 40 Sports Pylon. All the above props are suitable for use on .40 engines, albeit at lower RPM..
Also available, the 9.5 x 6.6 4B and 10.5 x 6.25 3B.
For modellers wanting a less expensive product, the Bolly clubman series propellers are perfect for the sports 40 / 46 market. Some of these are the 10.5 x 5. 10.5 x 6 and 10.5 x 7.
PROPS FOR R/C PYLON
The Bolly Racing propellers have been developed over many years of flying and testing. An extensive range is available for almost all classes possible.
Please note: We are changing all our newer props to a number code
For FAI we have our base 8" range and the variations moulded from the base types. For models using a 2" spinner, we have found it best to use the 8" props at 7.75" diameter. And for models using a 1.5" spinner, we use the 8" props at 7.5" diameter.
8 x 6 Now out dated unless used with an older engine.
