Larry seems like a decent bloke and is quite passionate about his prop design, but he’s saying the rotary only needs his lighter hub design (80-125hp VP-1 series), stating that the smoothness of the rotary negates the need to go for the heavier hub. Has anyone got experience with these props or know of anyone flying with one? 

other option is electric MT, but about double the cost down here.
