prop size
I am putting a 55 AX engine on this plane,but not sure what prop to use in a 3 blade or 4 blade.
The engine calls for a 12/7 or 8 13/6or 7 Not space for a two blade prop. Carey

RE: prop size
Biela makes 2, 3, and 4 blade props in many different size/pitch combinations. They also have some pusher props. The material is carbon fiber with a wood hub. All the props are balanced individually just before they are put out for sale.
In the interests of full disclosure: I do not work for Biela, nor do I receive anything from them for any sales that they may get from my comments.

RE: prop size
What's the biggest prop you have room for?
I have a pair of 55AXs on a B-25. I finally settled on 12x6 MAS 3 blade props. These let the engines turn about 10,500 rpm on 15% Cool Power, good for around 60 mph and gobs of thrust. They never liked any of the various two blade props I tried, including the ones recommended by OS.

RE: prop size
It's hard to find a lot of info on the Laker, it's an old Laddie Mikulasko design from RCM Magazine. The listing on RCM plans calls for a 40-46, and I'd bet that Laddie put that engine pod down low so that an 11" prop is probably as big as you can go.
You might want to think about a 46AX, or even electric power. I used a Turnigy G46-670 turning an MAS 11x7 3 blade on five cells in a Mikulasko "Arrow" flying boat, and it wails. The nice thing about electrics in "pod engine" flying boats is that the battery pack makes it a lot easier to balance the dang things. They really want to come out tail heavy.
