Default 40 size gas engine

Just one question is there a gasoline engine with a foot print similar to that of a OS 61fx? If so where do I get one?

You might want to talk to Horizon. They handle OS and also Saito and Saito has a 11CC gas that supposedly uses the SA61 platform. If that OS61FX has a rear needle valve you might have enough clearance for a rear carburetor engine.

I would look at the OS15GT. It's a little pricey but it is a beam mount front carb.
