That looks great! Already Flite Testing too. I am WAY behind.

Nah - you're not way behind, I just let my over-eagerness get the better of me. By taking a very simplistic design approach in sketchup and a pretty basic build approach I was able to move to a flying bird pretty quickly.

I am trying to picture a 3* bend at the end. It might not look too bad?

Thanks - another solid technical solution and I could definitely model the rear part of the exhaust to do this. Initially I thought that this would be too tricky for other builders (i.e. having them check this angle which by eye would be harder then just getting them to confirm that it was straight). But if I model the part that way and they assemble the pieces correctly (i.e. the glued seam of all the tubular sections is at the bottom and lines up between all the sections), then the angle will be there and will rely on how accurate they cut the part.

How scale is your model actually to the real thing when considering the distance above the main wing.

It's pretty good. The only significant scale "deficiency" in the model is the fact that I modeled the rear of the plane to be symmetrical top and bottom (which is not the case in the real model) and the details of the canopy.

The side view in your original picture shows (by eye) the angle to be closer to what the 2 degree representation you just posted appears to be.

I tried measuring this angle on the picture a few times but the tube does not seem to be 100% symmetrical so I got values of 0 degrees to about 3/4 of a degree down thrust. But you are correct, if you stare at it long enough there seems to be a down thrust angle in the pic. So I tried a different approach by overlaying the various thrust angle models over the three view profile and it seems that a 1 degree down thrust is about right.

So I will model in 1 - 1.5 degrees down thrust
