Spent some time on the build and I have nearly completed the tail feathers. So far, it has been very straight forward. Just some simple gluing and light sanding. The only observation I would make is that it would be nice for them to include some kind of template to help lay out the sheeting to keep it down to the 7 sheets they provided. I ended up using an extra sheet of balsa I had to make all the pieces fit easily because I couldn't quite get the jig saw puzzle solved of how to maximize the usage and minimize the waste of the balsa sheeting. Very minor problem though and someone that has built kits before could probably solve the problem very easily. I also used a scrap piece of balsa turned 90 degrees for the vertical fin to easily sheet the extended length that part R-1 adds to the structure. If you look at the picture associated with step 6 in the manual, you can see something similar was done but it was not pointed out in the text.

My plan is to start the fuselage tomorrow night and if all goes well and time doesn't get away from me, I hope to get most of that structure done by the end of the weekend.
