I am scratch building an Airbike from plans sent by Jordan Lake. I am to the point of just heating and bending up the bottom fuselage. I sort of followed the way Scrapper did it on his legal eagle video, I ran a line from bend to tail and wanted to cut boards at the correct angle to keep the tubes from sagging. I come up with about 82 degrees but the plans have a dimension of 85.

So, I popped the dimensions into solidworks (I don't have the brain for the math) and this is what I get.

So the question is... Should the tail post be 90 degrees to the top longeron or 85 degrees from the bottom longeron? It can't be both!
