I see now. I like the tie offs. It appears that takes care of the x and y movement. Nice job.

Finally, you are all done. Then it's time to assume you overlooked something that will eventually fatigue the tubing. So you super glue some pieces of thread from tubing to fuselage. If thread breaks, you have advance notice of fatigue failure down the road.

 

When I do creative stuff, similar to what you've done, I force myself to sit back and say: "It's going to fail. Now, where and why?". "What action will reduce risk?" Computer monitoring of coolant pressure is good one, as pressure will drop long before you run out of coolant.

 

Good job venting rad btw.
