I have a question about the flex header & pipe.
What is the procedure for installing and/or removing a one-piece wing ( I assume the great escape is a one-piece wing) wiht the pipe under the wing.

I have a new 90 size pattern plane wiht a one-piece wing. I am goping to put a YS 91AC on it & I have a header and pipe. I'd like to use it because of the same reasons you mentioned.

But how to put the wing on without disturbing the pipe set-up?

Thanks for the help.
