I just scored a batch of props off of ebay and in it is a new Mejzlik 14.4 X 13 prop. I fly big gassers and this size is foreign to me-where are they used?

B.L.E.

My guess would be two meter pattern airplanes, F3A. Loading the engine with pitch instead of diameter keeps the tip speed low and makes for a quieter airplane. They test for noise at F3A events and state of the art pattern planes are quieter than some sport electrics.
