Yes, at such a part there is no need for using the MTI hose around the perimeter. You can use it on one side or at both Wnds and infuse across or from the center to outside.

Yep, that's pretty much exactly how I do all my infusions with MTI.

I would put resin line in center ( perpendicular to length) then put 1/2 meter of mti hose on each end in a "u" shape. You will half the mti hose and won't infuse downhill ( unless you rotate mold as you infuse).

Yes, fold a piece of infusion mesh around the resin line and make a " flying resin line" to eliminate print thru from resin line.

I would recommend the setup like Hanaldo mentioned of running the infusion lines out the outside, running on the perimeter allowing the resin to run the shortest distance.

The benefit is that when over, the lines are on the excess/cutoff, and there is no print thru of the line in the part.

Running the way that is mentioned in the post above this one, with the line running inside has the negative consequence that the infusion line can become trapped inside the part at the deepest point because resin may begin to pool at that site.

I build wings very similar to the on that you are building, like I mentioned before, I have tried both ways of running the infusion and because of the sharp angle of the top of the wing, and because of the spiral being stuck inside because of resin pooling in the tightest portion of the wing, I can only recommend the first setup as the best setup for a type of wing like this.

Both ways will work for the infusion, but what I've learned is that running it straight through will leave you with a clean part, whereas the other method with the spiral inside may leave you with remnant spiral that is have stuck inside the wing.

The mti hose will only be on your vacuum feed.
