Since I'm more or less making things up as I go, I expect to have to make several versions of parts before I get them right. This stab is pretty good, but it may be heavier than it needs to be. And one thing I've learned about myself is that I tend to over-build, so I'm challenging myself on this model to make things as light as is practical, particularly in the tail area.
BTW, I found a mistake on the fuse. The vertical formers just in front of the tail post shouldn't be there! Looking again at the diagrams and other references, I realize that the line represents a single vertical steel bar in the middle that supports the skid.
VonJ, greatly looking DrI, by the way. Feel free to post photos or details.
