Thanks for the input.

I'm down to 2 planes for this...... a Q500 with my fx46 or my 60 size curare with a jett 90 or ys 1.1.

I am going to go out on a limb here:

In my small and overworked mind (inbreeding can do that) it comes down to thrust minus drag equals speed.

You can have the most thrust in the world, but you will eventually "max out" the airframe.

Conversely, you can have the cleanest airframe in the world and be limited by the thrust produced.........

Don't get me wrong, I LOVE the sound of a 2 stroke screaming at high rpm on a high-speed pass......but I also love a burley 4-stroke twisting a lot of prop.

My only point is that a 4-stroke with the right prop should produce comprable thrust to a "similar" 2 stroke, and therefore yield comprable net thrust on the same airframe..........

That should stir the pot pretty good.....I'll probably NEVER get into The Brotherhood now!

Now......we wait[]
