I have been testing a few different props lately and wanted to share my results with you. I tested these props on a Byron AT-6 running a Zenoah G-62. The results are shown below.





TBM.............................................To p Flite............................................. .... Bolly

22x10............................................2 2x10.............................................. ......22x10

RPM's.........6330................................ ............6900.................................. .....................6750

Weight.......4.5 oz..........................................4.0 oz................................................ ......4.6 oz


The TBM and the Bolly prop seem to unload and pull about the same in the air. They also seem to have about the same amount of noise coming from the prop. The Top Flite prop was the noisiest of the 3 and did not seem to unload as well in the air. The Top flite prop flexes a lot more than the TBM prop did which is why I think it lost a lot of pull once in the air. I would not hesitate to buy the TBM prop as it performed just as well as the Bolly.
