Is there any chart available with the thrust force (in newtons) that differnt engine/prop combos put out? OR any formula to roughly figure it out on my own?

There are thrust calculation routines available... but they will only give you an estimate.

You can build a fairly smple static thrust meter... or just tie a fish scale to the plane's tail and measure the pull. You'll find that the output changes with the slightest change in atmospheric conditions.

What are you trying to calculate the thrust for? This would point to how accurate the estimate needs to be.

I wanted to attempt to create some vector force diagrams. They are really just for my own use and entertainment. I would like to see how accurately I can predict flight characteristics for various planes. Nothing too super critical [img]i/expressions/face-icon-small-smile.gif[/img]
