If you want a ABC prop for your hydro let me know what one you want. If it is a ABC prop I should have it in stock. A lot of the guys here on this site might not know who I am, but everyone on Jim's RC Boat Dock dose. I have been a ABC prop guy for about fifteen years now. I sell a lot of props on the Boat Dock. I have always catered to the gas market on the props. I do stock almost all the ABC props done in 1/4" shaft sizes. You can see just what is hanging on the pegboard. In the larger ABC props I do stock more than just about anyone in the USA. Sometimes I might run out of a size prop, but I try to stay up on my inventory and not let it happen very often. If you want a high pitch prop I have all the 2.6, 2.7 and all the way up in diameters in all the pitch's made up to the 2.3 pitch. I even have the ABC 2727/2 and 3027/2 SAW props in stock.
