RE: Zingali prop
Ah, my dearly departed friend William Robinson had the answer way back in 2003.
Thanks Bill. I don't know if you have Internet accesses up there but rest assured that your still helping people out down here!
"I don't have any Saito .56 engines, but I'd start with the three balde Zinger/Zingali/J&Z 10x8, possibly going down to a 10x6 if I didn't get the rpm I wanted with the 10x8.
Reason for the "Slashed" brand is they are all the same prop and the same company, J&Z Products, but depending on the time of the month or whatever, you will find them listed as any one of the three brands.
Bill. "
