My post above was mostly in fun. This can be a hotly debated topic, and we all have our own opinions.

However, lets please compare apples to apples.

Claiming 50% more power from a .56 fourstroke compared to a .46 two stroke is just plain untrue. Please explain this one to me. Most .56 fourstrokes I have seen, are pretty close in power to a .46, and normally most people will use a .72 4 stroke in place of a .46 two stroke.

Another point I would like to make is cost. People seem very willing to spend big bucks on a 4 stroke, but overlook a premium 2 stroke engine. Compare a Saito .56 to a Jett .50, or a Webra .50 and you will see no comparison in power.

I have seen identical planes, one with a Saito 1.80 and another with an O.S. 1.60 and the power difference was remarkably in favor of the 1.60. All this, at $150 less dollars.

I'll agree with just about everyone about the sound of the 4 stroke, but the sheer power per $ numbers of the 2 stroke are hard to beat.
