RE: Bob Cat Copy Falcon 120 Jet
The whole point of having the tube go through the fuse from one side to the other is so it has strength. Cut the middle out & you might as well not use it at all. You could hysol the outer parts of the tube to the fuse sides, but I would not trust it. The forces would probably be to great.
I suppose a better idea would be to hysol the tube in the wing, leaving about a quarter of an inch to locate in the fuse.
