I still have not had time to do anymore testing with the B Y&O props. I want to try a 10x4 on my HP.40, as the 11" props were to much load. I think the 14x4 will work well on the Saito.72, but I still need to flight test it.
Kevin, every B Y&O prop I pulled from the package took a lot of work to get it balanced. I don't know if the hole is off center a little, or it is just that far out of balance. Tom
