"Perfect" clunk tank

yeah, I was just sitting here thinking about that run of clunk line and my fingers betrayed me and I had to type that out,,lol.

It would have to be some really supple thin wall tubing like the small texas timers stuff and a heavy sullivan clunk to make that kink-turn. That happened to me on a small tank and that certain TT small line. It looks like your run is thick and short enough to stay were we see it there. It should follow those edges quite nice.

Again, good job on thinking "outside the fuselage" and prompting ideas to the rest of the peanut gallery.

But for simple daydream flying, it looks to be a very good setup, Congrats!

It won't fold forward unless it hits something.
If the aircraft is held nose up for a full power check (in case the plane took a knock on the way to the field)
and shaken for 5 secs it should never happen.
