Ok so we are to the point of installing the pipe in the TGA F-15 conversion.

I decided to go with a straight pipe install and a P-60.
Well now after looking at whats going to happen to the rear fuse with a straight pipe, I really don't want to bucher it this much.
It looks like the whole plane ready to fly dry going to be right around 14-15lbs.

Am I going to lose too much thrust for the P-60 to move this plane out with a bi-pipe?

Tam does great work but man I really don't want to sink $350 or more into the pipe on this plane.
Anyone have any 12lbs turbine sized bi-pipes laying around?
Or any other idea how to tackle this?


Here is what the chop will look like......
